Bret....I guess it also depends on how much duration you have on the cam. The more duration....the higher rpms needed. Like stated above my hp curve was climbing and then the pcm shut it down. So....I know I will need to spin the motor higher than 7250 rpms to see the full potential. But like you stated...this intake will work well at lower rpms as well.

 

True....

3 years ago I put a 214/224 cam teamed up with a Super Vic and made 570hp out of it. TQ peak was 5000rpm HP peak was 6000rpm. Throw more duration at it and your going to get the same TQ peak and more rpm on the HP peak. The problem is the higher you want to move that HP peak up the more duration it needs.

Now if you just look at the intake manifolds, say a Vic Jr. It has smaller cross section runners and shorter runners. It also has a listed RPM range lower than the Super Vic. Problem is the shorter runners don't help make more TQ. The smaller cross sectional area is one of the reasons why the listed RPM range is lower. Now I'd want to see the proof that the guys who claim the Super Vic is too big for a street car have on the dyno? I've tested a Super Vic that was ported vs. one that had the runners epoxied up to cut the cross sectional area down and there was very little difference, enough that most guys wouldn't find enough to justify the cost of doing it. Wasn't just my idea either, when I thought about doing it I talked to Keith Wilson about it and he agreed as well.

yep, a buddy of mine here in town runs a Vic Jr./elbow/90mmTB/TF twisted wedge.. fed by a Novi 2000 on his '90 LX...thing makes some freakin power and it is no where near optimal tune

P.S. if anyone on here is looking for a TB too use on one of these conversions, i have a new in box Accufab 90mm for sale $225 shipped ($250 new) never used (pm or e-mail me)

EDIT:
"fast 93 z" , that looks awesome man. nice work!!
