Help with dyno results

NuclearMuscle523 · 09-28-2009, 02:31 PM

Went to the dyno. Came back with ~270hp ~270tq
Airfuel pretty much 12 straight across. I have the Hipo kit with 2.8" pulley
Wet-x kit also.
Shouldn't I be getting closer to ~350 for both?
Car is making about 7lbs of boost when it should be around 11. Even put a brand new belt on 10mm smaller to eliminate chance of slip and it is still making 7lbs.
And this was on a dynojet this time.

A DynoJet will read lower than a Mustang Dyno. Not sure why your boost is low, but I've never seen an X-Charger produce 350 rwhp on either dyno.

Someone correct me if I'm wrong, but don't you have the 2 dynos backwards? I believe the Mustang dyno reads lower than the Dynojets do.

You're right. It's the mustang Dynos that read lower than the dynojet dynos.

Your boost is low for the 2.8" pulley. I suspect there's still some belt slip going on. You should be around 8-9lbs with the 2.8"
