The ported Fast 92's we've installed and dyno'd have shown an average of 10rwhp gains on moderate LS1 H/C combos and about 15rwhp on the 400+ci engines. The fun part is, that it takes less timing to make more power with the intake ported correctly!

I assume those gains are with an out of the box FAST, not a ported version?

i picked up 20 with my home ported unit on my mild h/c setup stock cubes too.If you put on a PROPERLY ported unit to match your heads i bet you will see a 25-30 rwhp gain,probably closer to 25.There are so many factors though,your cam,heads,who ports it etc....

We've seen 10-15rwhp from porting the FAST over what it did out of the box. Sorry I wasn't clear.

Oh that I would say definitely seem worth it then. Maybe I will be springing the extra money for the 92-92 setup.
