Here is the final whp chart from my L15A1 engine dyno run on a Mustang Dyno.

174whp @ 10 psi

Now the fun part; We did a little testing so on my 1st dyno runs we did it with the intercooler uncovered and hood opened also in 4th gear. The next run was done in 3rd gear and you can see that horsepower dropped from 173whp to 164whp, I believe this has to do with the speed compensation being used on the dyno software.

To me, the more important bit of information is that the horsepower dropped another 4% when the hood was closed, this means the intake is sucking in hot (less dense) air and can’t breath (flow) enough on the top end… and you can pretty much see it all along the boost curves (blue lines)."

174whp is about 210 CHP

“No more upgrade for Mickey” Yet here we are with a new gt3076 turbo in place of the t28😐
