Lessons learned in Nashville

Coming into the second Eastern Division round of the Redline Time Attack series, a great amount of anticipation surrounded the outcome of Round 4 at the Nashville Superspeedway.   Round 3 in Joliet at Autobahn saw me lose by a second in the Street FWD class, and from the moment I finished my final lap, there was a nagging frustration in the back of my mind of knowing that I could have run faster.

All in all however, 2nd place was still an encouraging result given the circumstances.  I had the privilege of being a groomsman in Greg’s wedding the evening before.  While one would suspect my late arrival at 10:30am on Sunday was the result of being over-served (only partly true), much of it was due instead to a faulty nav unit which invited us to explore beautiful downtown Joliet.   If that weren’t enough, a weak/defectitve pin in the rear brake calipers of our tow vehicle decided to engage the e-brake at 70mph, causing the truck’s rear brakes to catch on fire. 

At this point I must express my gratitude to the Redline organizers who were gracious enough to allow me to get on the track, albeit for a mere 2 laps of practice.  I discovered I was nearly 8 seconds of the pace from the front runner in my class; a well-built, well-driven Dodge SRT-4 with twice as much power as my RSX.  Not having a clue what I was up against, but feeling that it was a bit of a David vs. Goliath battle, I decided to see how close I could push towards a 1st place finish.  After all, I was still the reigning champion for my class.  How hard could it be?

Running 8 laps on a track I really hadn’t seen in 2 years with a car I hadn’t even driven in almost 10 months was a big test for me.  Could I run balls-out lap-after-lap and hopefully get it right?  By the time I had run through my 6 competition laps, I had knocked off nearly 9 seconds from my first lap, with my fastest lap naturally occurring on the last one.  My friends and family were in awe as Todd (Redline’s announcer) rattled off my rapidly improving lap times with every pass.  It made me feel like an absolute rockstar and even I was pretty impressed.

It wasn’t enough.  Doug Wind and his SRT had run deep into the 1:39s. 

I wasn’t upset finishing second, but I was irked that I hadn’t been better prepared.  Finishing about 1.1 seconds behind with a 1:40.49 was acceptable, but I needed redemption.  I vowed not to let the SRT rain on my parade again.

The GT Motoring/Challenge/Seen It! Crew ventured back out to Autobahn a few weeks later with plans shake down Greg’s new S2000 which only saw 6 laps and for me to obtain a piece of mind.  Redemption came quickly in the form of running a few mid 1:38s.  Granted, most of my laps were around the 1:40 range, but this fueled a misnomer that would eventually take me out of the running for 1st place in Nashville. 

By midday at Autobahn, I was feeling comfortable with the South Course, knowing my lap times would have been sufficient to win.  With an egotistical charge of confidence I was now braking later and later, throwing the car through corners and the braking zones, getting back on the throttle earlier and earlier and forcing the sticky Bridgestone RE-11s to scream for mercy at every possible moment.  In my mind, I was driving like a man possessed.   However, had I only bothered to pay attention to my lap times I would have realized that with all the extra effort, I was actually scrubbing off time rather than improving it.

Round 4 took us to Nashville Superspeedway; a track I felt very comfortable with and was confident about despite my lack of power for the long straightaway.  I knew full well that my closest competitor had double (or more) the power of my car, but I was convinced that all I needed to do was throw the car around the tight infield portion of the roval and all would be fine.

In 2008 I had run a 1:11.9 at Nashville.  For 2009 it was determined that 1:10s would be a simple task despite the fact that the RSX was essentially unchanged.  All that was needed was for me to simply drive faster and more aggressive.  Corners that I had breathed off the throttle last year were to now be taken with a flat foot fueled with something to prove.  I kept telling myself that it was necessary to push like mad through the infield and that my efforts would far outweigh the time lost on the straight to higher horsepowered competitors.

For much of 2008, I was still trying to find the limit of the RSX’s capabilities.  The last time around in Nashville, I felt as though I had left a lot on the table.  So naturally the underlying instinct was to drive harder, brake later, accelerate sooner and throw the car around as much as possible until it was necessary to dial back a few notches.   Unfortunately, I maintained that mindset going into Nashville and the infield track tore me, my ego and my lap times to shreds because of it.

All of Saturday and most of Sunday saw me running in the low 1:12s at best.  Of course, I became frustrated and discouraged.  The car was understeering more than ever, forward traction was nonexistent and I was constantly finding the tires far greasier than I ever had in the past.  How could this be?  The Bridgestone RE-11s were reported to be a step up from the RE-01Rs and I was completely perplexed.  While there was a change in that my preferred Cobalt XR pad compound wasn’t available, there was no weight transfer under my late braking, the car just seemed sluggish and all the while I pushed even harder.

Following the first competition Time Attack session on Sunday, I had experienced enough torture.  Convinced that the new pads were the scourge of my poor performance, I swapped back to my Cobalt pads, which were on their last legs.  Greg’s S2000 had ripped out a wicked fast lap prior to the aging OEM differential blowing up, so with his day of driving finished I asked Greg to ride with me during the final practice session to see what was ailing my performance.

In years past, there had been a few occasions where Greg had either ridden with me or driven behind me so that he could pick up cues on where to push further or where to alter a driving line slightly.  I was always the faster driver/car.  I wondered what it’d be like when I’d have to ask for driving advice, but when the time came, it wasn’t awkward in the slightest.  Surprisingly, I didn’t find it the least bit ironic or humbling that I was now asking Greg for his assistance.  I have always regarded him as a consistent and smooth driver who always drove very well.  I had always assumed the difference between us was directly related to the fact that he had a higher regard for life than myself.  In retrospect, I learned that he was the faster driver for most of the weekend NOT because he wasn’t as crazy as me, but more because he drove in a much more cool and composed manner.

The Cobalts definitely did help set the car up better, as the stronger initial bite worked much better with the Bridgestones, allowing me to finally drive deeper and get on the throttle sooner the way I liked.  However Greg quickly pointed out that my inputs were far too aggressive.  I was over-driving the hell out of the RSX to the point where I was scrubbing off speed and inaccurately setting the car up for just about every corner. 

3771962941_703e0ee449_b

Greg’s advice wasn’t overly-technical (then again, my nickname isn’t Cole Trickle for nothing) knowing that the simpler the delivery, the better when it came to my level of comprehension.  He merely suggested that I try being smoother, try to take as straight a line as possible through the corners and encouraged me to try braking a bit earlier into the first high speed corner off of the banked straight. 

rsx-2-med

His advice was priceless.  It was almost embarrassing to witness how much it changed my driving.  My instinct was to barrel into the first corner, slamming on the brakes as late and as hard as I could until the rear end had almost completely rotated around.  By braking only slightly sooner and smoother, I was able to cut a tighter but faster line through the first hairpin, plus I hadn’t over-cooked the tires, providing me with the forward traction I was missing and even more lateral grip.  The first turn made all the difference.  The rest of the track seemed to slow down and the car seemed entirely more responsive.  Despite the noticeable changes, it still came as a surprise that I had run well over a second faster than the rest of the weekend’s times.       

3764809420_370c621dd1_b

 The problem was that it would have been nice if this revelation brought about a happy end to the story, but unfortunately it didn’t.  I didn’t learn of my fast practice lap of 1:11.0 until after a mistake-ridden final Time Attack round where the fastest I could muster was only a 1:11.8.  During the final Time Attack session, I once again lost my cool as I thought only of simply out-grinding the SRT-4 in the corners.  I misshifted, put too much heat in the tires and went off-track on my fastest lap.  While I didn’t completely throw out Greg’s advice, my own fighting spirit got the best of me and I lost sight of the task at hand. 

The moral of the story?  Be prepared mentally, run your own race and never, never, NEVER forget the fundamentals.  I spent the entire weekend worried about fighting the infield to make up for being ridiculously outgunned on the straight when I should have been concerned about taking the weekend one lap at a time. 

I must admit, I’ve even fallen victim to griping about the massive discrepancy in power compared to me and Doug’s SRT-4, but the truth is that he deserves all the credit for his wins.  Driving a front-wheel-drive car with that much power is no easy task, and while it’s easy to say that he simply won the race in the straightaways, the fact of the matter is that his car requires very steady braking, precision throttle control and management of such power, which is no simple task.   In noting that, I will be the first to say that he unquestionably deserves the wins and competing against him has been both a pleasure and a learning experience.

My mindset was all wrong from the time I had wrapped up Round 3 up until seeing my practice times only after the final Time Attack round had finished in Nashville.  While I have no doubt that both races could have been won for two completely different reasons, the underlying lesson was that they weren’t.  I didn’t drive my own race and instead psyched myself out worrying about my competition and completely overdrove the car.

Just when you think you’re starting to become a good driver, it takes lessons like these to give you the reality check that is sorely needed.  I’m just thankful to have such helpful teammates to point out what should have otherwise been blatantly obvious.   

A special thanks goes out to the rest of the GT Motoring/Challenge/Seen It! Crew including Nick Weir and my brother in-law, Craig Moore for keeping the car in top shape.  Also a big thank you goes out to Bridgestone for allowing us to look like rock stars in their big display and for all their support.  Also thanks to Enkei for their backing and to J’s Racing Japan for shipping out a much-needed tie rod just in time to allow me to even compete in the first place.

Wish us luck this weekend in South Carolina as Greg looks to finish on top once again and I try to get my head on straight at Carolina Motorsports Park; a track that appears to be both technical and very high speed.  It should prove to be another fun weekend and hopefully we’ll come away with even more fun stories to tell!

On a side note – All three top drivers in the Buddy Club Eastern Division Street RWD Class are running on CHALLENGE coilovers AND Bridgestone RE-11 tires!  Congrats again to Greg in his 1st place finish in Nashville and to David for 2nd place!

New GT-R Y-Pipe Prototype Review

Author’s Full Disclosure: I do not own, nor will I probably ever own a GT-R and I’m insanely jealous and envious of any and all R35 GT-R owners to an extreme and infallible fault.

Now that we’ve gotten that out of the way I’d like to provide a slightly biased outsider’s point of view regarding the race version of the prototype GT-R Y-pipe in development that Greg had alluded to a few posts ago.

Anyone who’s had the privilege of seeing an R35 GT-R in person can attest to the fact that despite the car’s heavyweight status on paper, Nissan’s engineers definitely honed their tuning efforts around the car’s bite factor as evidenced by its massive performance figures.  After seeing a few out on the road now, it seems as though they neglected to give the beast any bark.  Simply put, it just plain doesn’t sound mean enough in my humble opinion.

Here in the Chicagoland region, we’ve recently been treated to some nice weather (relative to the frigid abuse we’ve been subjected to for months) and that means everyone breaks out their toys.  I’d make a reference to the exhaust tones of the springtime air beckoning to fellow gearheads parallel to the mating calls of songbirds, but that’s excessively lame and I’ll spare everyone the pathetic analogy. 

Well, on Sunday that meant being treated to the sound of a well-ventilated Ferrari F430 running alongside my Honda Fit (not all of us can drive GT-Rs).  Being stuck in the typical I-94 Chicago Sunday traffic see-saw of 20mph to 45mph back down to 20mph, everyone was constantly on the brakes seemingly as soon as they had hit the throttle.  While at first the Ferrari’s V-8 was music to my ears, after awhile the resulting sound from the incessant “look-at-me” barking engine coupled with overabundant (and unnecessary) gear changing of the flappy-paddle-gearbox (as Top Gear’s Jeremy Clarkson has so affectionately pegged) from the middle-aged guy in the top-down F430 with the backwards Ferrari ballcap and matching Prancing Horse polo in 45-degree weather began to wear on my nerves.  BUT, it made me think; as much as it annoyed me it didn’t really matter because at the end of the day this man was driving a Ferrari and he could do as he pleased.  He was driving a supercar and no one else in the general vincinity was.  Most importantly, it SOUNDED like the tremendous supercar that it was, and that notion alone stuck with me.  (In retrospect, the sound wasn’t annoying.  The traffic was.  One such as me could never grow weary of such a sound.) 

Had that same car been a GT-R alongside me, would it have had the same effect?  Provided it was stock, absolutely not.

The day before however, some of the GT Motoring crew had gotten together for some karting action and Greg broke out the GT-R.  Upon firing it up, the sound was amazing.  The exhaust manifold on the R35 was the same, the rear exhaust section also remained unchanged, yet having just a subtle change in the Y-pipe switched out to the prototype race version made all the difference.   The sound was not overbearing by any means, but upon start-up, the R35 had a distinct throaty growl to it that compelled just about everyone to instinctively go “oooh” upon hearing it. 

At constant highway speeds I drove behind the GT-R and couldn’t pick up even the faintest of droning noise.  The sound was unmistakably noticeable, but by no means obnoxious.  Upon heavy acceleration and wide-open-throttle, the GT-R let out a howl that made the hairs on the back my neck stand up, yet the remaining stock exhaust components prohibited the noise from getting out of hand.  Hearing it in person is the only way to experience this, as I doubt any sound clip will do this piece justice.   While sitting at an intersection at idle, again, the sound is distinct, but not demanding.  

Overall, the prototype Y-pipe by itself in either the race or street application probably won’t be the end-all-be-all power modification by itself, but it’s definitely a phenomenal place to start from the sound alone.  While I’ve always preferred a louder car, I believe that this particular application will do an excellent job at fulfulling the needs of someone looking to make a very streetable improvement to their GT-R.   The sound is unmistakable, yet it won’t leave any bruises on your eardrums or those around you.  It also incorporates a design that is a departure from the norm of other Y-pipe designs for the R35 thus far.  However, the most important factor though is that this piece by itself provides the GT-R with the auditory signature that’s sorely needed for the car to make its mark when driving on the streets.  After hearing the prototype version in action, NOW the R35 GT-R at last sounds like it matches the supercar status it wields on paper. 

Check back on the GT Motoring blog frequently as we’ll be testing these designs on a number of different measurements - namely performance (horsepower) and sound, as well as for the official release of the product.

RSX Weight Reduction

As mentioned in my previous entry, while GT Motoring’s capabilities are endless, our personal budgets are not.  Therefore, some creativity and hard work were necessary to try and squeeze out even more performance from the RSX. 

 

Unlike its thoroughbred Japanese counterpart, the Integra Type-R, the Acura RSX was an Americanized, middle-of-the-road, watered-down, version with a slight identity crisis.  It was a bastardized Integra with Acura badges and overdone sound-deadening, sloppy Macpherson struts, heavy leather seats and brakes that would show signs of fade after only a few laps among many other deficiencies.  The Acura RSX appeared to be built to not necessarily appease anyone but to serve more as a stop-gap in a larger marketing plan that had just done away with the Prelude, DC2 Integra and other somewhat similar cars.

 

Yet for some reason both Greg and I saw potential in the car.  It did have a brilliant drivetrain with wide-ranging possibilities.  Its suspension and chassis, while initially frustrating, exhibited a night-and-day difference once coupled with better dampening, spring rates, a slight change in geometry and a good locking limited-slip differential up front. 

 

We were running out of time before the start of the 2008 season, and we had already added a significant amount of weight by ditching the ultra-light titanium J’s Racing 60RS exhaust for a custom designed 3” steel exhaust with a muffler and catalytic converter welded-in to comply with Redline Time Attack’s new Street Class rules.  To mitigate the weight changes Greg and I determined that a quick, cheap and easy fix would be to cut out all of the useless sound deadening tar that coated the interior even thicker than Line-X bedliner job gone horrifically wrong. 

 

We pulled out all of the interior components of the car, picked up about 60lbs of dry ice, broke it up and spread it around the car, shut the doors and rolled up the windows and went to lunch.  Upon our return, we grabbed paint scrapers, chisels and gloves and went to town.  Most of the sound deadening pulled up with little to no effort, making the initial removal an absolute breeze.  A good number of smaller pieces took up the remainder of the day.  To remove the final portion of excess seam sealer, epoxy and additional sound deadening, we attached a steel wire wheel to an impact drill and scraped up the rest.

The sound deadening by itself probably weighed between 25-30lbs.  Additional components such as airbags, seatbelts, rear windshield wiper and motor probably took up another 15-20lbs.  Removing carpeting, audio and electronic and other interior components probably saved another 15-20 lbs.  Swapping out to aluminum suspension parts, lighter brake calipers, wheels and exhaust manifold may have conceivably saved another 20-40lbs.  The biggest weight loss probably came in the removing of the heavy leather front seats.  Both were additionally weighed down with side-impact airbags and weighed nearly 40lbs each.  By swapping out to lighter seats we saved at least 40lbs, if not more.  More weight could definitely be removed from the car, however most of the basics have been covered for now.  While each part by itself may not be much, collectively it all adds up and does make a difference.  Especially in a car which is not particularly fast in a straight line by any stretch of the imagination. 

 

 

If I were to do it all over again, I would have been much more liberal with the dry ice by picking up at least 80-90lbs.  Being able to thoroughly freeze more of the sound deadening would have allowed Greg and myself to work much more efficiently.  It should also be noted for anyone interested in taking on a small project such as this that proper gloves and ventilation are crucial.  Dry ice can be very dangerous if applied to exposed skin.  As it evaporates, it also depletes the abundance of breathable air.  Therefore thorough ventilation is an absolute must.  It’s an easy project and can be a bit tedious at times, but if someone like me can do it, anyone else can too.  Just remember kids, safety first! 

 

I’ve also included a link to a video outlining the brief process undertaken in doing the project.

Time Attack-winning GTM RSX Development Summary

When building our RSX, Greg and I knew that we didn’t want to cut corners, yet it was financially irresponsible for us to dump massive amounts of money into a car whose driver still had much to learn.  We didn’t have the resources available for any fancy chassis improvements, infinitely adjustable suspension components or massive amounts of power.  We did have a decent amount of trial and error invested in building the car and trying things out on the track, not to mention an unyielding drive to improve our on-track and off-track capabilities.   

 

In fact, many of the parts on my DC5 originated from Greg’s immaculately-built RSX.  When he decided it was time to graduate to a more advanced platform, I volunteered my virtually bone-stock RSX’s components in a trade for much of what was on Greg’s car.  We spent a humid, 90-plus-degree weekend swapping parts from one RSX to another in his apartment complex’s parking lot.  It was also around this time that Greg discovered that I was the most technically inept, uncoordinated person to ever pick up a wrench; essentially he did all the real work as I sweated, grunted, bitched and moaned while trying to break even the simplest bolts.  Why he decided to keep me around is still a mystery.

 

We focused on components and parts that would deliver the best bang-for-the-buck, paying attention to covering the fundamentals more than anything else.  Good brakes, solid handling with improved suspension geometry and a responsive, yet affordable drivetrain package laid the groundwork.  Granted, the J’s Racing aerodynamic package may infer a completely different story, but we felt we needed to invest in a little bit of form coupled with some function to separate the car from the rest of the crowd. 

 

Could we have gone with a high-priced, 6 piston brake caliper system with two-piece rotors?  Or possibly thrown together a hybrid head and bottom-end engine package with high-priced internals and forced induction topped off with hours of dyno tuning?  Could we have engineered our own aero and other components out of lightweight composites?  How about running the lightest, strongest wheels we could get our hands on?  Sure, we could have.  GT Motoring distributes the finest parts in the market to epitomize both function and form and we would have loved nothing more than to capitalize on the full arsenal available to us.  Yet simply getting on the track to learn and drive was much higher on the priority list.  Therefore we made sure our homework was done and we used what we could to still be competitive, yet also ensured that we could make more than one event in a year. 

 

The end result and ongoing development couldn’t be better given the circumstances.  At many events the RSX was of the more underpowered entrants in the field.  Yet by laying a solid foundation coupled with some helpful driving hints from both Greg and GT Motoring’s technical director, Jae, I surprised even myself with the results.

 

A lot of work has been invested into the car, yet there is a still a significant amount of performance still left on the table.  Our development is by no means finished, however this next season will focus further on driver development and my own ability to help communicate to Greg and Jae the nuances of the car so that we can perfect our current setup and improve the functioning of the race team.  By doing so, it’ll also help us to develop an even better means to design and engineer new products.  One of which that I’m infinitely excited about is our new suspension offering (see Greg’s post from a few days ago about our suspension prototype).  Even more exciting though is GT Motoring’s new, from-the-ground-up S2000 time attack entrant.  As things develop, Greg, Jae and I will be certain to brief everyone on its progress.

 

While the challenges never subside, things are definitely shaping up to be very encouraging for the GT Motoring race team.

Old Skool - Tokyo Auto Salon 2007

You all know you’ve seen this sight a million times before;

You’re at a car show. You see girls. You see guys looking at girls. Some guys will make a little more effort than others. You may have even cracked a joke amongst your friends about the dude who is on the verge of irreversible paralysis from the embarrassingly extreme levels of spinal contortion as a result looking so hard. OR, you may be that guy.

Well, regardless stateside perverts can take solace in the fact that of course, they do it in Japan as well (like you figured they wouldn’t?!).

I had forgotten about this picture until last night I was going through a bunch of old files. I still remember when we got back to the hotel in Shibuya after a long day at TAS and Greg and I both started rifling through our pictures. When we landed on this gem we both laughed hysterically because niether one of us had noticed these guys the first time around.

Who is this guy? (Michael’s introduction)

By now I’m sure most readers know who Greg is (quasi-iconic figurehead of GT Motoring, I know) and so you’re probably wondering why anyone else would ever post in GT Motoring’s blog section.

I’m one of GT Motoring’s Time Attack drivers who helps as a part-time volunteer employee in numerous aspects for the company…not all necessarily good, mind you.  I did however bring a championship and a number of records to GT Motoring via a Redline Time Attack 2008 Season Series Championship for the Street Front Wheel Drive Class  from behind the wheel of  the RSX that both Greg and I have been building for quite some time.  Does having such a distinction qualify me for instant e-cred?  Could I maybe get some authority around these parts of the interwebs?  Absolutely not.

I’m nothing more than an open-minded novice driver with only a couple of years under his belt and a TON of things to learn.  My purpose in blogging on GT Motoring’s site (aside from a means for Greg and Jae to humor me into thinking I’m “special”) is to communicate to the general and interested public just how easy it is to get into road racing and motorsports in general.  In talking with so many people, there still exists a perception of disproportionately high barriers of entry into the sport, which couldn’t be farther from the truth.

In sharing my exploits and learning experiences my aim is to encourage people to become more active in the sport and to shed some light on what the guys do over at GT Motoring in terms of motorsports initiatives.   My feeling is that if someone can take notice of what I’m doing (or not doing), they should be able to think to themselves, “if that moron can do it, there’s no reason I can’t do it better.”

I’ll be the first to say that I’m not an authority on hardly anything, but I’m definitely learning as I go and I’ve got a phenomenal group of guys to help me out.   My posts are done with the intention of creating an active dialogue where people like myself can contribute by posting comments or questions, and more knowledgeable authorities can feel free to chime in whenever, so don’t hesitate to speak up!
