Man

Those are good numbers. I figured my corrected HP by the following:

I assumed that my car was performing per the Stage1 figures, so my assumed HP was 235. I then took the WHP lets say 185. and divided that into 235 and came up with a factor of 1.27. I then used that figure to multply my WHP by, in order to get my actual HP. I then divided the 185 by the 235 and got .787234. I changed this to a negative number and added 1 to it, which gave me.212766 or a figure of 21% for pwr train loss. So if I took and subtracted 21% from the published HP (215HP) for the PT cruiser I would get a WHP of 169.85 which would be what I would expect a stockPT GT to produce. If I took and subtracted 21% from the 235HP figure for S1 I would expect to see 185.65 at wheels when I dynoed it. If you have a stick, I think that you should use a figure of 15-18% for drive train loss which would make you come out to 182.75WHP stock. Keep in mind that I was under the impression that higher math meant that I could count to 20, using both hands twice.

Sounds Good to ME! My daughter is in her last year of engineering school @ CMU and I can appreciate you response. Especially as it relates to a previous DYNO TEST.Your a TRUE gearhead.

All I know is he hurt my brain.....I believe the dyno has a feature that spits out a CF for each run based on ambient temp and humidity, elevation, etc., which is what I used in these instances. What I would really like to do is see what it lays down after icing that intake down for 45 minutes like a I do at the track. This usually nets me at least 1-2 tenths.
