Anyone got one of these Harrop intakes on a LS7? How big a gain did you see over a ported Fast 102 intake? And where there any tuning issues?
Hi, I cannot speak to gains over a FAST, only the OEM LS7 intake. Gains in peak were 10 rwhp, however we had to lift off the gas at 6000 RPM as my car started to spit oil onto the headers' collectors and was smoking quite a bit. I think we would have had another 5-10 rwhp till about 6500 RPM. So in peak it is probably around a FAST, maybe even the MSD, however you do not gain anything with these below 5000 or 5500 RPM.
With the Hurricane we gained 20+ rwhp (at some locations even 30+) everywhere. Am I allowed to post links to another corvetteforum page here? I put up my results about a week ago with some images...
