Default dyno'd my 03 s2000

i dyno'd my 2003 s2000 23000 km on sept 11 at SNK's race dynojet in richmond, bc and did 2 runs with mods: Spoon air filter, Spoon CF airduct, T1R testpipe, T1R exhaust, T1R epower voltage stabilizer, T1R grounding kit, and street tuned VAFC...

1st run at 77.8 degrees F
max power=199.8 whp max torque=134.5 @8300 rpm

2nd run at 77.8 degrees F
max power=204.4 whp max torque=136.0 @8300 rpm

both reaching speed at 78mph and both plot #'s are corrected

from all the other s2000 i seen dyno'd here i guess i should be impressed with the #'s but in a way seems a little low from what i see online..

Do you have a baseline dyno? If not, you should get a friend w/ a stock '03 to go up there with you and dyno on the same day. That way you can take out dyno calibration issues, and see where you really stand vs a stock car. Those numbers definitely sound low for a car w/ a test pipe. What did your air fuel ratios look like? Maybe you were running rich/lean? Also, maybe it's possible your engine was heat soaked. I found that I lost >15hp when my engine was suffering from severe heat soak.

will have pics of plots once scanned and uploaded
well considering that there were 7 other s2000 at that dyno day and most of them got lower #'s than me 195whp-200 whp etc...there was one s2000 there that dyno'd 197 whp with mugen intake/exhaust/header and other mods done like mine also so i guess maybe its the dyno that needs calibrating or maybe its right..i dunno...also my friend dyno'd his s2000 in bellingham bone stock and got 186 whp..so maybe here in vancouver we get lower #'s who knows...well here are my plots

Thats stock around stock #s but its normal, I mean MODs dont really add much to the s2k. Maybe at most 1-6hp with basic mods i/e/h etc. Dont sweat it man. good dyno.
