LS1 w/ TR224 and truck manifold
Sorry the graph is kinda blurry, but I don't have a scanner and did the best I could w/ the digital camera. The truck (which weighs 4450 btw) has gone 8.9 @ 82 in the 1/8th since I added the headers. I'm really happy with the torque curve, and there is definitely some hp to be had with a good tune. It's running a little rich, but I've only had the tune changed for the bigger injectors, never had a dyno tune done at all.

In my point of view, there looks to be a restriction up top. I think it may be the last two words in the title of this thread.
The reason I think this is because most LS1s w/ a TR224 & LS1/LS6 intake show peak power @ 6000-6200rpm. Yours flatlines at 5400rpm.
Hey, could be wrong tho!

Interesting...anyone else think the truck manifold is choking the truck up top? Could it be anything else? I know first and foremost I need to get a tune and lean it out a little bit, but anything else?

I could be wrong but I think the truck manifold has been compared to flowing as much as, if not better, than the LS1 intake. Parish (jim) would be the one to ask on this as I think he used his truck manifold on his setup's all the way up to the 408.

Yes, it does flow better than the LS1, but not as good as the LS6 or FAST. I would think that Jim's application is a litle different since he's forcing air through the manifold with that huge turbo.
