Anyone have any experience or comparative results with the TPIS modified LS6 Intake Manifold and their oval 90mm TB vs The FAST Intake Manifold and a ported LS2 TB? Tuning info would also be helpful. Best,

TPIS Oval 90 TB on a 346 is the best all around combo. I dont have data on me, but i would not go with a Fast intake unless i had big cubes.

TPIS did a comparison awhile ago. Do a search on LS1tech.com and it should come up. The FAST intake with a 90mm TB has consistently proven to be a worthwhile addition to a Heads/Cam car.
