Not Just Another GT2 Build..

So March seems like GT2 month at Champion Motorsport. Our yellow GT2 from last month is back for round II of mods, a white GT2 is on the way, and in the meantime, this amazing meteor gray beauty is only just beginning it's transition into a true race car. A race car that will compete in one of the most legendary endurance races in the US....the One Lap Of America. One Lap is 8 days of grueling races and testing that push both the driver and car to the limit. It not only requires a capable car, but performance that's both reliable and repeatable, principles that we've based our entire tuning program on.

The story begins about 3 weeks ago when the owner of this GT2 contacted me looking for some guidance on building a powerful race car to compete in the One Lap of America event for 2012. He had already decided on the GT2 to be the base platform, and after some lengthy discussions about the possibilities for improving both power output and, perhaps more importantly, versatility and reliability, the search began for the perfect GT2. As fate would have it, this meteor gray gem was for sale about 20 miles from our location. Only 1900 miles on the odometer, bone stock, completely loaded with carbon fiber and deviated stitching EVERYWHERE, and even a full leather PCM....we'd found our car! Within a short time, we took delivery and the fun begins! Here's a couple pictures on delivery...







This will be one of the most complete turbo builds we've done in a long time, where we'll be addressing both power and handling, along with a few other precautionary and reliability-based mods. The team here knows a thing or two about endurance racing , so some of that expertise will definitely be coming into play. The power package of choice will be our 68mm VTG turbochargers with complete power package. Maintaining low end power will be key to staying competitive in several of the One Lap events. Because One Lap uses a variety of venues, from skid-pad testing to road course racing, we'll also be creating a suite of ECU programs using GIAC's flashloader technology to accommodate high power and low power programs in both race and pump fuel. This will be one heck of a fun build, and I'll be making updates daily or whenever possible.

Work began a couple days ago as the engine and trans come out for round I of mods. Stay tuned for more as the build moves on...

Never get tired of seeing a gt2 (or any porsche for that matter) with the motor out for mods. Looking forward to the results.

It definitely will, from both a drivability and reliability standpoint. The GT2 Pro LSD is offers lockup on acceleration and deceleration for a much more equal delivery of power at the rear wheels. They're made from hardened 4340 chromoly billet and rated to handle 1000hp.

The owner of the car will be sharing driving duties with a "co-driver" who is a friend of his. Sorry...no names...not sure if they're OK with posting that online.

Sounds good will stop by.

When do you plan to have it done for testing?
One Lap is just around the corner.

This one's for One Lap in next year. He's done a few of them in the past but had to skip this year. It'll be good this way, so he can accumulate some seat time in the GT2 before the event. But we should have it ready and on the dyno in a week or two at the most.

Oh darm that is too bad, this years One Lap is shaping up to be a banner year.

Either way it is a great event not to be missed if you love cars and tracks.

Nice work Tom cant wait too see the results.
How does that ram air intake from gt2 wing compared to your air intake system with 997tt wing? I think that gt2 wing gives a lot of advantage on rolling acceleration because it pushes a lot of air in to the air intake. How can we get it work with your Carbon fiber air intake.
