GUYS! Don't forget this is on a different brand Dyno. So, while it gives a FAIR idea of what to expect. He could very well net 10-15hp on the other dyno. And look at the possible % of error just in the last 2 runs. Did they stop at 5900? If so, kinda silly since we can go higher. The limited is like what, 6300? If they did dyno higher, for both cutout runs, and the difference is 4hp from 220rpm, that's quite a change. Based on that, we could be looking at 5-9hp. Tack on the differences in Dynos, and there you go.

What would've been interesting to see was how ice packs in the gap of the intake helped out, if any.

Do you have a graph of the last dyno run as well? I was hoping the longer runners would also shift the graph a little lower in the RPM range.

Thank you very much for posting this stuff. It's obvious that these were very rough numbers considering it was two different days on two different dynos. At least there was SOME gain. I'm sure you could get another 10 or so hp/tq from fully porting it.

I have a printout of the previous dyno. I will post that tomorrow when I get it scanned. The peak seemed to move up just a bit. I had them run the car to 6200 today since it wasnt making any more power up past 6k anyway.

If I recall, the days were similar temp wise and conditions but my old printout isn't very detailed as the one I got today.

My exhaust is hooker lts, mufflex y and dynomax muffler.

Peak moved up in the powerband with the cutout closed both times? Interesting.

The cutout was closed on one run. The 370+ ones were open. I just realized I goofed in my previous post. EDIT TIME!
