Every car, motor setup, intake setup, etc is all different. There is no certain mark for what your boost or power will be, everyone will tell you that with these blowers, including ati. I have a 45 and 88 yes. My Car made 901 hp on 22.95 psi at 6200 rpm. The car then made 24 psi at 6900. car ran out of fuel. No more tuning till I upgrade fuel issues.Originally Posted by 98blownsnake View Post
What cog pulley combo are you running upper and lower ?
Upper is the super sprag, designed to save the headunit and crank. They only make it in one size, Ill have to look, lower is biggest they offer. Hit 24 psi at 6900 when it ran outta fuel. Car is going to be maxed at 7200 rpms, no telling whats left for it to make.
I have the ATI Sprag upper pulley and it's 45t and I have the biggest lower you can fit 88T. I make 26lbs of boost @ 7K 687rwhp.
45T upper and 88T lower = 26lbs @ 7k F1a blower speed = 73920 rpm
45T upper and 88T lower @ 6200 rpm F1a blower speed = 65472 rpm about 16lbs. of boost (from my datalogs).
So your making 901rwhp @ 16lbs of boost ?????????
Im sure it will be fun, its still in the trailor, I have amillion things going on. Now that it is getting warmer, I will go out and play in it sometime soon.I do envy you as that is some serious HP for the streets as well - Would love to go for a drive in that car
