Boosted f22

[93exsedan]

I have a f22 that was rebuilt pretty recently, and I've been reading a lot about boosting it. How many pounds would you say is safe and still gonna be reliable for a stock f22(stock rebuild)? I've seen some people saying 8 lbs., but I want to hear from some people who have actually done it. What kind of gains should I expect? Will I keep up with h22 cb7's? Thats really all I want. I have a buddy with a h22 cb7.....and I'd love to smoke him with a f22. That would just kill him...lol. Thanks

8lbs is about standard on a stock F22A. 10lbs can be done. If your motor is freshly rebuilt, with good parts (and done properly) then it may be able to take more... but I wouldn't risk more than 10lbs if you want it to last.

Of course, this depends greatly on what turbo you use. If you use a little hairdryer like a 14b, or worse, a t25, you're going to be blowtorching your motor at 10psi. Don't get a small turbo. Something along the lines of a t3/t04 hybrid is best (trim and specific details are up to you). It'll be safest for the motor, and it'll also make more power. It does cost more, though (but less overall than blowing up that new motor would cost you!)

TUNING is most important. You MUST tune a turbo motor. Without question. You can get it running on a basemap, but that is not meant for regular driving, and certainly not for hard driving. It's meant to get it to a tuner, and then tuned properly. My ECU is tuned because the guy that paid to have MRX flown out to Philly blew his motor, and I slipped into his timeslot


The general rule of thumb is that turbo will generate 10hp for every pound of boost. So, 8psi = 80hp. Now, that's highly dependent on many factors... it can vary greatly. However, if you gain 80hp over the F22A, you'll be putting down more power than the H22A. Torque will be significantly more as well... turbo torque KILLS NA torque. The only ways you're going to lose against a stock H22A is if you can't drive, you can't get traction, or you break something.
