UL, nothing to read coolant temps and I have no idea about load time. Can you explain this?
Thanks
UL, doesn't 195 seem a bit low? Also, do you need to push the car to the revlimiter to get the most accurate reading? Will doing so cause any damage? What is your protocol for dynoing?
Thank you....

Does your exhaust have a silencer installed in it? A silencer cost 13 RWHP on a friend's NA S2000.

Also, who adjusted your valves, and are you sure they were done correctly. I did mine wrong the 1st time I did them. I accidentally set the clearances WAY LARGE by measuring between the cam lobe and roller rocker, instead of the adjuster screw and valve spring retainer. I lost significant HP from that mistake.

Gernby,
no silence, but they did have that damn hose on the end of my exhaust. I know it was restricting b/c I blew it off twice, despite the fact it was attached with bungie cords (no one else had that problem, but they are all running duals). I had the valves adjusted at the dealer.
Thanks for you input. Its appreciated.

With a Dynapack you have to set the load time. Within reason, a longer load time shows more power because less energy is expended overcoming the inertia of crank, flywheel and other rotating drivetrain masses. Most important is consistency in load time, but a quicker load time could have reduced measured power. I usually use something in the 500-600 rpm/sec range.

I've always felt like my IK24s provided benefit.
