Mustang Dyno Run

Dynoed my car on a Mustang AWD Dyno on a cold day in January.
I am/was impressed with the results.

574WHP = 700CHP(assuming 18% driveline lose)
620WTQ = 750CTQ(assuming 18% driveline lose)

Car running on E85/Protomotive Tune and driven daily this way

Note:
Dyno shop had no fans to blow air onto the intercoolers, saw an IAT of 70*C
in the logs made of the runs.

Yes Champion Gen1 Modded VTG Turbos(63.5 Billet Wheel) untouched hot-side.

What surprised me was not seeing the drop in power past 6500 rpm that I have
seen on most other modded VTG turbo dyno graphs.

Car feels awesome and boost start building by 2000 rpm, afraid any upgrade my introduce lag.
Need to upgrade the fueling system if I run bigger turbos on E85, so am leaving the car as is.

Looks like a great setup! Interesting to quantitatively see the importance of moving air over the ICs as well.

You can actually run a kit with tial A28s with less lag. Look at this volumetric efficiency graph from TTDude. He runs proto modded VTGs.
So you might consider a kit like a Switzer P800 if you ever want to upgrade without introducing more lag. Like you said you would have to do a new fuel system to continue with E85 though...

One of these days hope to take fan's to same shop and re-dyno with them blowing air over the inter-coolers

Had spoken the Todd and he had recommended Alpha 3071 with upgraded fueling.

I am pretty sure A3071s will have more lag than VTGs. The A28s with good supporting mods can match power of 3071s with much less lag.

Yeah, the A28s are darn impressive on Mike's set-up. You get more all across the range from down low to up top. A 5.5s 60-130 with no lag is like the ultimate street machine.

Thanks Scott.

The torque hits hard peaks and holds from 3500 - 4500, makes the front end go light and the rear steps out when I get on it.

Congrats on your build! One question, did you dyno your car in Houston and if so where?
