850 Dyno Run (2.4L Non-Turbo)
8/10/19 Straight Pipe (w/ Cat) + IPD Filter
Low results... The dyno they use is an AWD Superflow WinDyn "Heartbreaker" style dyno (usually reads around 20% lower than a dynojet) that reads WHP. Put down a pretty terrible 61.6 WHP at 6000 rpm and 65 ft/lbs between 2500-5000 rpm. What I didn't know going in was that you are meant to run the car around for a while or warm it up on the dyno prior to making pulls. (Coolant was up to temp, but oil and transmission fluid weren't, increasing losses) Engine has good compression (around 190 psi on each cylinder), new-ish plugs, wires, distributor cap/rotor, etc. I'm going to do a full stage zero and put a muffler back on it. (Thinking the cat-only exhaust system may be a detriment to exhaust scavenging)
Any other ideas tune up wise as to the cause of the low output?
