H\C\I and now Headers Dyno
Strapped the car down today at Boost for Boobies. First pull since installing the headers, previously made 375/352 with the H\C\I setup. It made 414/376 today, I also didn't realize the printout was STD, previous dyno's were always SAE. That put's my real numbers at 398 and change. Not exactly where I wanted to be, I'll probably get it retuned for the headers and see if I'm closer to where I expected.
UPDATE: Strapped it down again after tuning it, 414/380 up from 398/372.

I'm not sure of the specs on that cam but I would say you should be in the 400-450 ballpark with that. Some people say that a 102 and large diameter primaries slow down the intake and exhaust velocities but I haven't really bought into that. I feel that it's mostly in the tune and how aggressive you want to run it.

I would get it retuned also. Def don't take offense but I would have thought with those mods you would have pulled harder on me being I'm stock except for muffler delete. Also, if I saw correctly, your still running the stock cat back. How much hp is being left on the table vs a full exhaust?

So u have a ls2 with ls3 top end? Lsa actually flows a bit less due to wings than the ls3 heads unless you cut the wings out. Lsa and ls3 are virtually identical other than that. Fast102 on a ls3 is pretty much no gain over a ls3 intake. But I really think you should be showing a bigger number than that with that cam. If the heads are stock...430-450, yeah, possible. Pending tuning.
