Compression numbers in relation to dyno numbers
 

Hey guys

Got the car dyno'd today, after a few weeks ago getting it compression tested by go48. It got 175, which is a little low for what I thought it'd be getting. It is stock except for a tanabe exhaust.
The fuse was not pulled, he said he turned off the dsc though.

When I did get back in it after the pulls, traction light and the abs light were on. Had to disconnect battery and the traction light was still there, car wouldn't hold idle either(stalled). Finally all the shit cleared out.

Either way, here are the numbers. Seems pretty low so I wanted to get your guys thoughts. Looking at the sheet, doesn't seem like he went up to 9k. It was a dynojet

a bit low, but not unheard of.

wow! a tanabe exhaust will get you 8whp?

mine is stock! a k&n drop-in isn't exactly a intake... and RB duct, well.....

but '07 with 167~whp iirc. but its mustang dyno and i don't think he did it right as i don't haave a graph with a curve.

ouch, im gettin mine dynoed this upcoming week, with my mods im hoping anywhere between 180-195 whp... not even sure what a stock one puts but thoose are the #s im hoping for atleast..

are you driving an auto trochoid?

i havent dyno'd my car. but im pretty sure im putting down more than 167whp. we have seen rx8s run 14.4s in the 1/4. you need more hp than 170whp to hit that in a car that weights 3180 with driver.
