HHi , guys im new in this forum. anyway I am running a t3t4 hybrid with 50 trim, and I would like to know how much boost should i run safely but to make power. I dynoed 285 hp @ 14 psi on stock injectors im getting 720's next week. how much boost can i run ? oh and i ran with a nx 50 shot on the dyno 348. hp

Our engines can hold 20PSI+ from what I have heard. I run 17PSI on my FP Big28 no problem.

i'm running my 50 trim at 20-21psi on a bone stock 2g motor--327hp 310tq, its burns oil and needs a rebuild.

another 2g guy with a 50 trim on his stock motor is runnin 24psi--387hp, ?tq

anyways, you can run 20psi, probably not on stock injectors though. with your 1g head you should be getting real nice numbers since you can flow more than us 2g guys stock for stock

well i dynoed 285 at 15 psi on stock injectors and it was runing rich. i didnt boost more because i am afraid it can run lean ? also in colder nights should i run more fuel or less fuel ? and what are your o2 reading for the o2 sensor mine are at 70-80 volts and i heard thats lean but on the dyno it was off the scale rich ???

my timing is getting pulled way back cause the duty cycle on my injectors is pretty high, need bigger injectors

my AF ratio is pretty good though, 12:1, safe

 

[sarge]

are your numbers crank hp? they gotta be, cause a buddy of mine put down 387crank hp at 24psi, i put down 327 crank hp at 20psi

you definately need bigger injectors though, another one of my buddies was hitting boost cut at 14psi on the 450s

no the hp was at the wheels, this was at twilight performance down here in miami, fl. i hit fuel cut in 4th gear. really bad....
