they said probably like 22whp-28whp on the cams with no tunning so you assume with all that possiably 200whp

 

intake+exhaust+tune = 160whp, add the estimated 20-25 for the cam, thats only 180-185whp, (see brandon and jerryg's dynos for 160 esimate)

Based on these estimates, we'll need headwork and forged pistons (maybe 11:1 CR) to tip-toe into 200hp NA.

 

tune before cam yah...180-185, after cam, I think MAYBE 200, more then likely low 190's.

 

dont forget those guys did not have header/DP,none of you guys mentioned this now maybe you have 2hundred

 

I thinkk Sushidog already has the dp/header so whoever gets the combination of either the cams and header/dp will be the first to hit 200hun

 

one good thing about the cams on you car, that you won'thave to worry about that I had to, is the boost by pass valve.

I gained more boost so as soon as my boost passed the preprogramed level, the boost by-pass valve blead all my boost .

but as soon as I did the by-pass mod, holy power. hope everything goes well.

 

Yessir, I'm ready with full I/H/E. All I need are the cams. I've also got a Wester's "hot" tune, dual e-rams (good for an unverified 9% hp boost) and a set of 34lb SC injectors anticipating the need.

Cause I've got the need, the need for speed....

G5mike, do you have any other valve train mods ie: springs or retainers? Did they give you any advise on the rev limit with a stock valve train? My auto is tuned to shift a tad over 7 grand. I hope this is not a problem.

 

Im ki8nda curious of this too. I know my stock 2.4L manual will rev to 6800, but I want to replace the springs, retainers, and valves for higher rpms oh say around 8K or a little less. What wont hold up to this? I've posted questions before and no one answers them. What has to be replaced from stock before 8K rpm is realizable?

 

Don't know if you've seen this -- The GM Sport Compact book mentions aftermarket valve springs, Retainers and seats on page 69 for cams up to .500" lift without any head modifications. It's interesting that the book says if you use cams with .466" lift you need to use these aftermarket springs to prevent coil bind. Note that this book lists only 2.2 and 2.0 modifications -- maybe the 2.4 has redesigned valve springs? Anybody know?
