[Luca11]

Hey Guys, anybody know what kind of engine 99-04 saleens have, and whats the most rwhp it can handle.

 

[saleen556]

4.6 sohc just like the GT.Most agree 400 rwhp is the safe limit.

 

[Luca11]

More power

What would you need to do to be able to at least 550rwhp.

 

[Jonsey]

You would need to forge the bottom end, upgrade the tranny and clutch and upgrade the rear diff if you want absolutely no issues.

 

[SyberSaint]

Tranny

You would need to forge the bottom end, upgrade the tranny and clutch and upgrade the rear diff if you want absolutely no issues.

How or what would you upgrade the tranny to??? Just want to know

 

[Saleen87-65]

t-56 6spd or tko transmission, you will not reach your HP goals on the saleen supercharger, you'll have to go aftermarket. Built bottom end is in store without question

Find an S281-E car or a Saleen Cobra as a starting point. It can be done with a
2 valve but it's only a matter of time before something grenades.
