My name is Adam Pintek. Welcome to my Project GT90 Supercar.

Ever since I can remember, I have been addicted to supercars. Unfortunately, the price tag has gotten in the way of fulfilling my childhood dream of owning one. Then one day not too long ago, I thought to myself, “Why not just make my own?”

I grew up in Porterville, Calif., where all my friends worked on cars. This was a great environment to ask questions and learn. And throughout high school and college I was always tweaking cars; doing fiberglass bodywork, engine swaps, and building turbo kits.

Project GT90: By the numbers
Engine 6.2L V8 twin-turbo
Engine layout Mid-Front mounted
Power (projected) 1,000 bhp
Frame Steel tube frame
Weight <2800 lbs
Wheels (front) 9.5in x 19in
Wheels (rear) 13in x 20in
Suspension Rocker-arm
Brakes 14-inch, 6 piston
Transmission 6-speed, RWD

So, here we are, some 10 years later – after building some confidence in my knowledge in auto –I’m setting out to build my dream supercar from scratch. Literally.

My goal is to build a supercar that will outperform a factory-built supercar from the likes of Bugatti, Koenigsegg and Lamborghini. Once complete, my car will have a mid-engine twin-turbocharged 6.2L V8, pushing approximately 1,000 horsepower to the ground through a custom tubular frame and 13-inch wide rear wheels – all of which will complement the aggressive look of the car’s design.

Coming from NVIDIA, it’s somewhat appropriate that this entire project was inspired by a video game. Need For Speed 2 introduced me to the 1995 Ford GT90 concept supercar. I instantly fell in love. Inspired by a stealth bomber, the GT90 had a look that I have never seen before or to this day.

The GT90 concept never made it into the production line, which drove me to become obsessed with this car. The fact that even the most well-heeled car enthusiasts could not own one made the car that much more elite.

I am currently in Stage 1 of this project. Mostly focusing on fabricating body panels and in parallel I am working with a Formula racecar builder to fabricate the final tube frame and integrate the engine and racing suspension.

Stage 2 will be all about getting the car drivable, beginning initial suspension tuning, and also finalizing body panels. The fundamental aspects of the car should be in place at this time. Hopefully this stage will begin in early Q1 of next year.

Late next year, I plan to start working on Stage 3. During this process the engine will be completely rebuilt and turbocharged, along with the more suspension adjustments to assure the power of the engine is effective. This step will be the game changer.

Expect updates from me periodically.

[Update: Rear wheel is 20-inch in diameter, weight is <2800 lbs. Text edited to clarify]

    I’m confused. You say you’re in stage 1 of this GT90 car. Then what is this white car shown in the pictures?

    Some of your proportions and the flow of the rear quarter into the back of the car are not correct. If you’re not too far along it might be worth it to contact ford and see if they cant send you some scaled exterior blueprints for reference only.

    Christian:
    At this current moment the car has a mockup frame to allow me to fabricate the body panels.  In parallel I’m having a tube race frame built for this car.  Once the frame is complete and functional I will then put the body onto it.
     
    Rick:
    Yes, the rear body is mostly underdeveloped at this stage..  I have a big checklist of things to do for it.  :)

    Thanks for your comments!

    I want more info on your powertrain. Where’d you get the 6.2L? It looks like it’s from GM, which I find curious because this is a FORD sports car…

    What transmission is that? What’s your differential’s gear ratio? What bell housing did you use? What turbos will be used and how much boost with they be pushing? 

  • Bill Conan

    do you want to put a tegra 3 driven central control into your car? digital dashboard? like that of tesla model s?

    Being a fellow car build

    The engine looks like the LS series. It is hard to tell which one from these pictures. As for building a Ford with a Chevy engine, well, pistons know no logos. Use what works.

  • http://pulse.yahoo.com/_M6Z3PWFLBWSSK66QNX6BBBQHMY Shane

    That would not be hard to do. The OBD II engines already give out all of the dashboard information and it is easy to send that via Bluetooth. The HVAC will take more work, but with modern microprocessors (like Arduino) it is doable.

    Are you going to mold your own lens? Now days with 3D printers and silicon molding, they are not hard to make.

  • http://www.facebook.com/people/Adam-Pintek/602391425 Adam Pintek

    A Tegra dash system is definitely the game plan.

    It’s an LS3 all aluminum engine bolted directly to a 6speed TR6060
    converted for a true mid mount setup.  I chose this combo because it
    allows the engine to set directly between the front and rear wheels for
    optimal weight distribution.  The transmission and engine will be fully
    rebuilt and turbocharged boosting in the area of 18-22psi +or-…  I
    guess I will find out those details once this hits the dyno shop.

    Thanks!

    I’d like to donate my arduino. :)

    So can you upload some pictures of the current process your at? i’d like to see everything from mock frame, to panel forming, to final product. Good luck

  • Chen testaR

    Would you please allow me to use the fotos in my report?
    I’m from Asia, and work for a auto website, sure i’ll give you the link after done.

    Funny to see a car story at the NV blogs. Hopefully this guy spreads the news to some actual car sites.

    I have always wanted to do a build like this but since I don’t have the time, money, or space yet, it’s exciting to read about your build.

    What kind of engine management system are you going to run to push that kind of boost, and how are you going to clear the motor with the BAR referee in order to get the car registered and street legal?  It was my understanding that CA is pretty strict about aftermarket FI parts and engine management and everything has to have an Executive Order number, so unless some large company makes a kit and fronts the money for the E.O. certification it is a no go?  That kind of stuff has successfully deterred me from custom FI setups so far.

  • Will Park

    I could be wrong here, but I don’t believe emissions will be a problem with getting this car street legal. There is a “hobby car” registration option available to the most enthusiastic of hobby car enthusiasts in CA.

    An Arduino isn’t the best choice for OBD2 work.  While it’s pretty easy to add a MCP2515 and transceiver to a shield (I’ve done it a few times, including for an EV DC motor controller), there are many tasks that the 8 bit processor takes too long to do.  You’ll find yourself spending a lot of time to tune and test the code for real-time response.

    And if you want to use the Arduino/Wiring language, forget it.  It took me about 30 minutes to get a working environment (Win!) and decide that it wasn’t capable enough.  The really great thing about Arduino is that it loads a correctly-packaged C language environment so that you can immediately move onto productive use.

    I’ve now switched to using ARM microcontrollers.  The cost about the same, while being far more capable.  The peripherals tend to be quirky (buggy), but the ARM core is well understood.  And there are quite a few that have built-in CAN controllers.

    If anyone is interested, my code for this is up on Google Code under ‘obd2-instruments’.  I implemented full OBD-II reporting over CAN bus, a series-DC motor controller PI feedback loop, and a few other pieces.  There are versions for the AVR/Arduino hardware w/MCP2515 as well as a few others.

    And anyone working on automotive, EV, or CAN bus that would like to chat, I usually sit in SC C12.  I’m interested in everything from fabrication through power electronics.

    Great work man! This has been one of my all time favorite cars and yes I remember the good old days of need for speed 2. Although my favorites were the Lamborghini’s and the Mclaren F1 I always had a place in my heart for the GT40. You should post up your good work over on http://www.madmechanics.com The boys over there have been following your build apparently and we would love to hear from yah. Jay aka VF1.

    So this is why the Tegra 3 Kal-El processor has been pushed back three times. All the engineers are outside in the parking lot drooling over this.

  • Aaron Hoy

    Well I hope you’re right, but some of the accounts I’ve read from other custom cars seemed to imply that basically the same laws as regular motor swaps apply.  Meaning you have to provide proof that the donor vehicle was junked, and the motor has to have all the same smog equipment as the original car, not have any modifications to the intake, exhaust, etc., and still be OBD2 compliant if the motor was from a 1996+ car.
