Fast 90 Vs TPIS oval 90 LS6 Fast 90 Vs TPIS oval 90 LS6
Does anyone have and info on comparing rwhp and rwtq or track times of the two intakes on a stock cubes ls1or ls6 motor?
What one do think will make better ET on stock cubes?

Does anyone have real results of the difference between the Fast 90 vs the TPIS oval 90 LS6 on a heads/cam 346 engine? TPIS claims more low end torque vs the Fast 90 and about the same power in the upper rpm range vs the Fast 90.
Both of them move a ton of air, I would seriously doubt you could find any notable difference in performance between them. I went with TPIS strictly because of the problems I've heard about with FAST.

But you are using the TPIS 90mm TB on the 90mm Fast intake not the TPIS mod to the LS6 intake with the oval TPIS TB correct?

They were both the same as an Ls6 until you go to the upper RPMs, and then they both pull away. You gave up nothing on the bottom with a FAST.
The FAST was ~+10 on HP and TQ over the TPIS modified LS6 intake....
