Looking to hit hi 280-300 with mild internals on an LS. Is this possible or am I dreaming...

setup:
Rev hard turbo kit with t3/t4b
hondata s200
3" exhaust
440 cc injectors
v-afc boost controller (boosting at 15 lbs)
Crower pistons and rods at 9:2 ratio

 

very possible

A dyno, and a reputable shop. Get that **** tuned.

 

get bigger injectors. Yep you can get 300whp, I would get as different turbo as well. I'll be making over 300 next year. Now im making close to 270 on a cold day who knows .

 

hey hybrid, did you change your LS head at all? what kind of setup is yours. I love those numbers of yours with just 11psi.

 

with the right set-up 300 whp on a ls is pocket change.

Nope everything is stock. completly I keep the revs were they belong, my moto: the more you rev the more you tear. I just put the right things together and made great horsepower. I just looked at other people set-ups and seen what they were making and i knew what i would get. I looked at an old post i made a while back, before i was tuned people asked me what i would make i said 260ish.I was right on the money when it came down to it. Jus tput good products together and have a great tuner, and a have a healthy enigine you'll have fun.

 

yes, you could have done it on stock internals fine..

 

12-14 Lbs should do it with some good tuning. It varies depending on the condition of the motor ...

 

Get it tuned by Jack, and you'll end up walkin home

Typo? Did you mean the AVC-R? cause afc won't control your boost as far as I know.

 

Hmm, I didn't know Crower made pistons... Are they decent?

 

what turbine on the turbo? i have a t04b/t3 w/ a stage 2 .48a/r housing and hit only 230 at 10psi. to hit 300 your gunna need at least the stage 3 .63 housing.

otherwise, yeah, it shouldn't be that hard.

 

I hit 260+ at 9.7 PSI on my stock LS with a T3/T04E 60 trim .63 AR, with very conservative timing... Tuner thought we could have gone for 275+ easily if he had a knock sensor, he didn't feel comfortable tuning timing much more aggressive without a knock sensor
