Dyno : 1995 Dinan (Powerdyne) Supercharged M3
Got a chance to finally dyno test the M3 over the weekend and figured I'd post this up since everyone seems to like dyno charts . :)
- 100+ degrees inside a closed off dyno room
- 88 degrees outside temp
- Cooled off about 5 minutes with the hood closed after a 2hr drive
- The choppyness up top is probably the belt slipping a bit since I really didn't tension the blower pulley all that well after rebuilding it a week ago.
- No AF graph since I didn't have a wideband bung :(

Re: Dyno : 1995 Dinan (Powerdyne) Supercharged M3
comments... the jagginess is probably NOT caused by a slipping belt; most supercharged E36 cars producing strong dynojet results, with a smoothing factor of less than 3 on the Dynojet software, will produce a somewhat jaggy plot.. dont worry about it; the only time you need to be concerned is if you see 'spikes' of greater size than this.
Also, you should post your plots showing SAE correction factor; not Standard.. You cant compare your results to anybody without doing so. In addition, the STD correction factor produces results that are higher than what the SAE factor does. Its the SAE results which people compare; not the STD result.
