I hear you on this bro. I'm messing with stuff to try to eek out the last bit of HP on my car but I'm thinking that we are on the limit with the 650 kit.

You could upgrade your fuel system (pump, injectors) pretty easily but no one's tuned for it yet so that's the issue. Who is going to try that? If you are already 560-580 to the wheels with a 650 kit, then an e85 tune would theoretically put you beyond the limits of a stock CR M3 motor. The tuner would be running the risk of blowing your motor for 30-40 HP so there won't be any reputable tuner that would want to do this.

As I think about what I want from this car vs what I can do with other cars, I toy with the idea of doing a build and raising both boost and redline. I'd love to have this car rev to 9,200 RPM or beyond and make 650+ wheel...but then I think of what I can do with a 911T or R8 V10 and I struggle with what I should do next.

My car makes 560whp......i think it is the fuel system that is the hard part ess said on there post on this they are testing a new vt3 fuel system so it's best you wait till they get that right

Do you use your car everyday? I think build a motor use it everyday and get something else for the weekend

With all this boost on a stock motor and driving it hard it most likely will have to have a build one day just depends on how long you plan to keep the car
