The Forbidden Supra·
I don't really care now, since my car is no longer bpu... but I was just curious, how dangerous is it to run say 25-27 psi with the stock turbo system w/stock computer and no fuel management? Because that's what I used to run all the time in the high gears and never had any problems at all. Several people I know like to run crazy boost like that too on stock turbos and they haven't had any problems either. I'm just curious... because everyone makes it seem so incredibly risky to run more than 18 psi and more than 15-18 degrees of timing with a single turbo setup... yet there are people running 27 psi with small inefficient turbos at potentially up to 22.5 degrees of timing! Why is it that they are not blowing their motors to pieces? I assume part of the reason is because bpu cars run quite rich, but I know one of the cars is fairly tuned, at least in the 11-11.5:1 range.
