745hp/679tq @ 39psi

Postby redlineracer21 » Sun Mar 30, 2014 1:29 pm

Finally took my car to get dyno tuned. Very happy with the numbers, especially for a mustang dyno. All of the pulls were done in 3rd since 4th gear overloaded the dyno...

Heres a video my tuner put together for me.

I just noticed the dyno says 29.97. did you mistype or did u run 39psi if so 745 seems low compared to the 609 u made on 20psi.

Fuel setup is dual walboros, -10 feed -6 return. Precision 95lb/hr primaries and 165lb/hr secondaries and e85.

Clutch is a 350z specialty z clutch. 5 puck with d21 flywheel.

The dyno only went up to 30psi but aem was showing 39ish.

The reason the numbers are low was because we had to do 3rd gear pulls instead of 4th. We tried one pull at first in 4th and overloaded the dyno by mph. We did a back to back pull in 3rd and lost around 30hp just from switching gears. This was also on a mustang dyno that reads low compared to dyno jet which is what the 609hp was tested on.

So your easily making over 800whp. 39psi on a s366 is def 800+

I request a spedo video of 3rd and 4th :) . Pleaase
also if you can get a 4th gear pull somewhere with a bit of tweaking , i think you would have the first 700wtq ka. Better beat kedbmx to it he should do the same with his new 10.5:1 setup.

Sorry i was wrong. This graph was a 4th gear pull and apparently he changed the mph limit for this one. The reason for low power is most likely due to the t3 backside is getting restricted. It really needs to be t4...

That's awesome.

Looking at the chart it seems like the HP peak is a little low in the RPM range.
Do you think that's a result of the T3 exhaust housing?
What cams are you running?

The t3 def is restricting the power in the upper rpm range. It starts falling off at 6300 when it should keep climbing to 8k+. Still one of if not the best powerband I seen on the site. I shift at 7 n only made 630whp n ran 10.5 he should be deep in the 9s!!

It peaks early due to the small housing. Builds boost quicker so hp comes on sooner. I run the bc 272s cams.

Thanks rosadoracing! My goal is to just see a 9.99 sec pass. If i can get further that would be awesome.
