Just like the subject says, I am looking for dyno curves before and after a stealth ram swap. Preferably on a mostly stock L98, and not using a chasis dyno (ie. flywheel #'s). Also, preferably no other mods made at the same time, just a manifold swap. This is what I would ideally want, but I would be interested in any stealth ram before and afters just out of curiousity. I am trying to compile before and afters of some of the various manifolds so that I can compare them to each other as far as what effect they have on the power curve. I found this which has exactly what I am looking for, but I feel that the stealth ram could do better than this.

So, whos got some for me...

The best I could find is a hi-flow TPI base verses a HSR.

Thanks John, that's a good one I hadn't found yet. When compared to the other one I posted above it shows that the stealth ram is not happy on a otherwise stock tpi engine. It needs heads and a cam before it starts to really shine. I also found another one here . This site also has a ton of other info on the stealth ram for anyone who is interested.

Still looking for a stock L98 before and after with a stealth ram. It's not looking too good, but we'll give it one last try.

Anyone

do a search, there was a topic a few months back about someone who swapped the tpi on his stock L98 for a hsr and actually went slower in the 1/4 mile. i would only go with the hsr if you plan on changing, or already changed the heads and the cam. if you dont plan on touching the heads or the cam, just stay with tpi or go with long tube runners. lt1 intake might be something to look at as well.
