Your best bet for launching your car should be at about 4500 to 5000 w/drag radials. But on stock tires your not gonna get much traction out of that if you go over 4500 your just gonna keep spinnin and lose valuable time. Traction is everything you can have a 300 hp car and still get spank by a car with less hp if you cant catch traction.
If you want pwer boosting is the way to go. But on a stock motor dont push your luck by boosting over 6psi unless your planning to build your motor or swap. You can go more than 6psi but the wear and tear will eventually catch up sooner than you think.
