Fast 92 vs 102
FWIW - on my 383 LS1 with a 229/229 cam, the whp difference peak hp in a Fast 90/92 and a 102 LSXRT was 1 whp. And ~3-5 wtq this was on a chassis dyno same conditions etc. Not exactly an LSXR but in the ball park. With a bigger higher revving cam, I suspect the LSXRT would have been ~ 5whp to 10who better than the smaller intake. Neither intake was ported. The Fast 90/92 was better drive ability wise.

Hio, how much do you port on the 102s? Do you just do the insides of the runners, or have you ever tried shaving the "ribs" off the outside of the runners such as in these threads?

The references I posted were on the 102's where they shaved the ribs on the outsides of the runners. My Mamo ported 102 doesn't have the ribs shaves off so obviously Tony doesn't mess with doing it on his ported intakes. Just wondering if that's for time/money reasons, or if it doesn't provide much gain for all the trouble.
Oh, dang, it would be interesting to see what kind of difference it made. You hurt the FAST or the whole engine?
