As long as the 75 shot doesn't give you 150 hp .

LMAO I dont think it will. Maybe 100 or so but a grip load of torque from what I am hearing.

If you don't get into the 6's it's gonna be super low 7's that's for sure!

I've been reading articles from a few different mustang magazines using 8-10 boost as a forced psig. They all attempted to run the blower with 24lbs injectors at 400HP and were running out of fuel. Even at 80psi fuel pressure, they had drop off at the end of their dyno run. Once they shifted to 30lb injectors, they were able to run at maximum HP without the excessive fuel pressure. I'm going to give my 30s a try and see where I end up. They also tried the 42lb injectors and the cars did not run well on the street or at idle. Of course, a lot depends on the tuner. Can someone please find a tuner that I can trust!!!!!

I don't know why they stopped making the 36lbers. That's what I just sold to papatom. I think they would give you a better cushion and don't cause the hard starts and part throttle issues. You may be just fine, but it would suck to find out you weren't while you are on the dyno.

I've decided to go back to Swanson performance in Torrance Ca. Once my tune is finished you can decide if you want to go there or not. You could always tag along. I plan on going up there with papatom next friday if my injectors ever get here.

I start my travel on Wednesday and will be gone for 1 month. Let me know how it goes and please ask some question for me. See how much it would cost to chip and map my car for the new blower.
