hey guys, whats a good a/f ratio at redline? or wat should it be at?

Raven SS

what are u running?

usdm08

its that i was runnin a 2.7 wit 42's n i know i was runnin lean but i wanna know how lean i was runnin now when i change the pulley

Raven SS

ur injectors prolly went static...if ur not running meth i would say 11.5-11.7 is safe zone

usdm08

yea becuz wit the setup now around the 6000 something rpms its around there but when it starts gettin to bout 7000 its starts goin up n at redline 7200 it hits 12.0 or 12.2

Raven SS

who tuned ur car?

D4u2s0t

if you don't have a great tune, i expect a boom runing the 2.7 on 42's.

usdm08

i have the gm stage tune


n i been runnin my car like this for over a year now

D4u2s0t

yea, that's pretty stupid. actually, that's VERY stupid. you either don't drive your car hard at all, or are doing alot of damage even if you don't realize it. get rid of the 2.7, OR get a tune/bigger injectors.

your injectors can't keep up with the amount of air you're moving. a 2.9 on the stage tune is the "safe" limit, many people have blown up their cars with a 2.8 and stage tune. 2.7 is just asking for trouble.

also, what cooling mods do you have?

usdm08

thankz man

D4u2s0t

you're welcome. if you don't have any, i would also get some cooling mods. you may be losing power AND doing damage with all the heat that 2.7 is making.

usdm08

i do have a h/e. hey let me ask u something whats the normal coolant temp on that car wit the h/e ?

D4u2s0t

not sure. mine runs around 179 without it. what does yours run at?

usdm08

the lowest it been it 180 wit it n its always around there but somes times it will go to like 220 n then drop. but i live in miami hot as f*** always lmao

ShortStack

I live in west pam beach mine never goes about 187, and thats only after i turn off the car, let it sit for like 30 min in the sun... then it drops right down to 180... 183 if im pullin on it on i95..

brett5

the coolant temp has nothing to do with your H/E
