331 Dyno #'s Dead @ 5100 RPM (Long)

red82gt · 04-15-2005, 12:17 AM

First off, what type of dyno (mustang, dynojet, etc..)? Next thing, what does the A/F do when the power falls off? Also, how much timing are you runnning?

It was a Dyno Jet, total timing was at 28, the AFR dropped slightly. I'am going to get a new MAM and TB and hope it frees up some power when it's retuned. I know full potential will not be achieved with the GT-40 Irons, cant afford new ones right now though.

Does anybody have an estimate on how lean it will get with a 73 mm MAM and an aftermarket 65 mm TB. Once I get those on I will not be able to get it tuned for several weeks.

Thanks For The Help!
