Any idea on who built his auto trans or what upgraded clutches he used ?

This thing would be 800+ AWHP if it was on a dynojet. Super impressive, this car hauls!!

I felt like something was off on this thing. I have a near identical build except I am a stock compression and Speedtech bottom.

Did you dyno yours? Got a log?

Shit mine isn't even built yet. Should be getting my block back from machine shop next week. Already have everything to put together. I estimate it will be running before end of month.

Oh, so why did you think something was off with this if you have nothing to directly compare to? lol.

35 PSI on a 6466 and built head...those are low numbers. Impressive build!

Not for AWD mustang dyno.

For example a TT e92 M3 on Gintani's mustang AWD dyno did 747whp.
They went to Specialty Z (same dynojet we use) it put down 860whp LOL. Huge difference.

I think he was referring to 726 awhp being off as a low number considering the engine build and psi. Most people think in terms of Dynojet numbers and don’t realize the Mustang dyno has more than earned its reputation as the heartbreaker.

This is an XI record if I am not mistaken. It must be fast as hell out of the gate on a 40 roll!!

Bring on the front LSD’s!!

Is something up with that dyno? first that weird dip ~3800 and only seems to have revved out to 6100? Hard to read the rpms/left axis but looks to have made more than 725 whp at 5750(?) more like 750?

The spool setting on JB4 is way off. boost is overshooting by a lot and correcting back down to under target. Then going back up to target

Hard to tell exactly whats going on without a log, but that could be the case because it's on a dyno instead of the road.

That was my fault guys. The graph had those dips because I was rolling into boost rather than matting the pedal to the floor. Anyways, I've attached another pull with the pedal to the metal and the graph looks much better.

Probably would have made more awhp but only had one heat treated o2 in bank 1 for testing and kept one eom Bosch o2 in bank 2. That bank 2 with the Bosch sensor kept giving me troubles so we had to let off sooner than what we would have liked. I have since ordered a second heat treated o2 for bank 2. The heat treated o2 in bank 1 handled 35 psi without a hitch!
