2004 Cobra Single 76 Turbo Auto SRA 9.19@154 813rwhp
Hi guys,
The short version: 04 Cobra with a Precision 76, Built 4R75W, Solid Rear Axle. I've driven the car two hours to the track, swapped the rear wheels and tires, ran 9.19@154, swapped the tires back, and drven two hours home without a hiccup. With a fresh set of tires and a little more boost this car would be a serious contender for Hot Rod's Drag Week small block power adder class. Made 813rwhp on a peak boost of 23.8lbs and could make more.
EDIT 3/15/2015: I've received a lot of questions about returning the car to "street" trim. I'd like to be forthright and say that this car is closer to a race car that can be driven on the street than a street car that can be raced. Are there things that can be done to make it more "streetable?" Absolutely. I'd recommend replacing the solid suspension components with urethane, and installing an automatic valvebody and a US Shift kit to replace the manual valvebody that's in there now. Unfortunately, things like the A/C, ABS, airbags, and rear seat would require extensive work to reinstall, and I would not recommend the car to anyone looking for any of those things. That said I'm lowering the price to $19k. If you have any questions feel free to ask!
The long version: It's a 2004 Redfire Cobra with just under 47,167 miles on it. The turbo kit is the On3 performance hotside leading up to a Precision 7675 turbo and a custom downpipe that flares out to 4" and dumps under the car. I have the On3 after-turbo parts in case someone wants to quiet it down on the street. This car is a monster street car with loads of power.
Race weight this past year was 3165 with me in the car (175lbs) so the car is quite light.
Timeslip below, 9.19@154 with a 1.37 60ft on a set of used Hoosier 28x10s. Backed it up with a 9.21@152. I expect nothing less than 8's out of the car with a fresh set of 28x10.5s, it has the MPH to get the job done, just need to bring the boost in sooner.
