I have a 2.3 Whipple gen 2 with a 3.0 upper and 2# lower. Car is only making 16lbs of boost on dyno, 520whp. Any ideas what could be causing the low boost readings? Changing to a 1/2" smaller belt as we speak. Other ideas?
Longtubes, 2 1/2" exhaust no cats, stock longblock. Was expecting to see 20-21psi.What other mods do you have? Headers, stroker, ported heads? How much boost do you think you should see? Belt slip?
Those are STD numbers. The SAE numbers would be around 500-510. That is real low for his setup. How old is the blower? Whipples are famous for needing to be rebuilt after not too long. You may have a boost leak somewhere also.
I had an issue like this before. It was down on compression in two cylinders. Wound up being worn valve guides. Hopefully that's not your case but do a compression and leak down test. Good luck.
That's good to hear. Hopefully, it's something simple.Did a compression test before I went to the dyno, 140-150psi across the board. I talked to a tech at Whipple, he gave me a few things to try/look for. Hopefully its something simple.
Nope. You lose maybe 1-1.5 lbs of boost with headers. I dropped only 1 psi.You lose a few psi with long tubes that's bout where you should be with 17 degrees of timing.

Op, did you ever change out your intercooler tube o rings? It's maybe not the problem, but it's happened to some.
But I also wouldn't want to run anymore than 17lbs on 92-93 fuel.
