Any before/after LSX 78mm--->90mm results? Has anybody gone from a 78mm LSX Intake to a 90mm LSX and dynoed the results?
I lost 1hp going from a ls6 intake to a 78mm lsx with bolt-ons, and I'm sure a 90mm lsx wouldn't have helped either.
If I had gone with a 85mm lid and maf, 90mm tb, and a 90mm lsx intake which would have increased the flow but lowered the velocity anybody think I would have gained anything with just bolt-ons?
I have the Hotcam in my car now, so I'm going to test the 78mm Lsx and the ls6 intake again and try to test the 90mm also.
With Godspeed's results it looks like the lsx isn't worth it until you have at least a large cam and even then you should go with a 90mm lsx instead of the 78mm for the most power.
