Went back to the same dyno yesterday, that I used way back in Sept. 2009 for the original dyno session, with Marshall (92TypeR on honda-tech) to see what the results of my current setup would be and try playing with the cam gears a bit. We were short on time, so only had a chance to try two different cam gear settings. Our first dyno pull before any tuning netted us 231whp and ~160wtq, if I recall correctly.
Setup changes worth mentioning since the last dyno are:
-Private Label Mfg. Tri-Y 4-2-1 Header (previous was GReddy Header w/ 2.5" modified collector)
-3" Short Ram Intake w/ Blox Velocity Stack & Filter (previous was 3" Fujita F5 Cold Air Intake, no velocity stack)
And here is a before/after comparing one of our graphs from our previous dyno session back in 2009 to yesterday:
I am definitely quite pleased with the gains. Clearly this setup is working pretty well....better than I had expected
Thanks! I didn't expect the header to make such a difference honestly. I figured my GReddy 4-2-1 wouldn't be too bad since I had modified the collector to 2.5".
Nice numbers Mike! I plan on getting a set of 11.5:1 CR Mahles pistons too to get that power. I have the same setup you have except I do not have the pistons yet.
Nice! Did you find a good shop that has the proper tooling to hone our FRM cylinder walls? I wanted to go with those pistons too, but no machine shops in my area seemed to be able to hone FRM cylinders.
Thanks! Definitely most of the gain was from the header. I think we only gained about 4-5whp peak from tuning the cam gears. We only tried two different cam gear settings on the dyno due to time constaints.

lord oh MIGHTY, you gained 22whp from tuning with the new header and cam gear adj. thats insane. i can't believe that header boosted hp that high. can't wait for a legit tune with no time constraint.
