I got dyoned this weekend at church automotive. I thought i had a 7# pulley but the dyno read it at 10 psi boost on CTSC. My numbers were 329rwhp 200 lbft tq. Those numbers look right for 7 lbs but not for 10. Any one know the reason. other than the SC and AP2 exhaust, i am stock.

 

hmmm no idea. My vortech with just testpipe and spugen 63mm single dynoed 348.5 rwhp and 215 rwtq on just 7.5psi. It read 7.5 on shawn's dyno.

 

could it be that im being restriced by all the stock parts? i.e exhaust, injectors, cat and so on.

 

maybe...what was your afr?

 

dang, i cant remember. I got AEM EMS tuned by church so i know im good. forgot to mention that

 

Your AFR's were pretty much right on 12.0 throughout the RPM band during full throttle pulls.
I'm guessing but I bet you could get more power with a test pipe.

 

^^probably but i think i will wait for a few more mods, throw them all on at once and get tuned again. looking for injectors, test pipe and single 70mm exhaust.

 

i was going to ask.. if you dont have bigger injectors you wont be able to run 10psi.. stock injectors top off right about at how much power you made.

 

He was running higher than stock fuel pressure. (Your comptech FMU was bottomed out )

 

would i need anything else besides bigger injectors to safely run 10 psi. im non aftercooled right now. i think that should be another addition along with the rest
