Can you run on GTiR T28, 370 injectors @ 3 bar and stock maf?

In my car, anything above 9psi on 91 octane pings. I've hit 10-11 psi with race gas and the car ran just fine. I'm sure I could've squeezed out a couple more psi but my maf (stock) and injectors (370's) were pretty much maxed. For a track (1/4) run I think it would've been okay. If your looking I have a T28, 370's in fuel rail for sale.

Ok, just checking. I just got done reading over on Greg Perry's site about him running his best 1/4 mile of 12.80 @110mph and I quote "According to the Techtom CMX-100 monitor, I only used 92.3% of the 370cc/min injectors capability on that run". Was running 11psi.

Was looking and found a T28/manifold and J-pipe. BB setup in the car right now. Upgrading the turbo, then will work on the maf, injectors and reprogramming the ECU. Just needed to get an idea of what kind of boost I could run. Thanks for the offer anyways.

Greg was on the 4 bar fuel system on that run and I can't remember if he had the S3's in yet or not.
Sure was, just re-read the article. He ran 13.25 @ 103 9.75lbs boost on 3 bar. So I will stick with 10 for the time being.

Good call, Josh. With race gas, you can go a bit higher. Your O2 sensor won't like it, though. :(

I did not have the S3 cams in when I made both those runs in June of last year. The cams went in about 2 weeks ago. Hope this clears things up.

I run 12 daily on the BB setup and have run 14-15 @ the track without any problems on 93 octane. Although the turbo looses its effeciency after 14lbs.

I'm not sure if my motor is 10:1 or 9:5:1 but that should'nt matter right

Yes it will matter. My motor is 8:5.1. Higher the compression, the greater the possiblity of detonation!!
