stock LS1(internals and all) with 317s, ls6 yellows and 7.4 chromemoly pushrods. I was going to just run stock WG spring, which is 5.8psi, but now that I have lowered CR due to the heads I feel like I can get away with more boost. Would it be feasible to be able to up the boost to lets say 9psi??

You can go for around 550rwhp and be alright on stock internals.....as long as tune is good

cant stock ls1s boost 10psi? and u have a lower compresstion since u have the 317s.

I was told beyond 8psi, they have issues with blowby but since I lowered CR that should allow me more boost.

I ran 10psi on my stock motor with a cam and headers

Awesome! Did Frost send you a base tune and you modify it or did you actually bring your car to him?

He tunes my car in person, but he does do tuning by email if you buy hp tuners. You basically keep sending him logs.

Yes with the boost it will be alot of logs!

He is doing a 228 cam car for me now.

You will probably come in just under the limit of those valvesprings. Much more boost and you can expect float. As long as you don't up the rev-limiter too much it will probably be fine.

and just remember it's all about the HP you are throwing at the motor not the amount of boost. Yes a lower compression is good to avoid other harmful things from happening (detonation, cyclinder pressure issues, etc). But you are a step ahead of a lot of people.

Hey if you ain't tuning it yourself have Frost do it he'll steer you in the direction as far as whats going to work and what won't. He is VERY knowledge.

FROST=MODULARTURBO approved LOL

Haha, my plan was to have him do the base tune and have it dyno tuned locally. Lol, good to know you approve of his work!

Mods in sig..... Stock block, heads, cam and 9psi

10 psi with a good tune is nothing, mine has seen 15. Only difference being a cam, better valvesprings, and head studs(which are probably not needed).

XtremeDime

iTrader: (16)

Do you guys run 9-10psi all the time or do you run a boost controller to drop the boost down for daily use?

MUSTANGBRKR02

I plan on running 10 on mine. Should start today if i get the tune.
