I'd be interested to know how much $ these HP/TQ increases cost? Maybe HP per dollar to get an idea what power costs. Thanks!
In my case it works out to between $16-20 per horsepower. With a larger DP, if I could fit it, the price would be around $10 per hp assuming I could get another 30 hp on top of the 570 hp we did @27 psi today.
Dyno today with 50/50 Meth/water. 557 whp and 400 lbsft Tq. @21 psi, 93 octane.
Didn't check ambient temps, but it wouldn't have mattered, the meth/WI cooled things down nicely. Upped the boost to 27 psi and did 570 whp and 425 lbsft Tq.
2-1/2" dp getting to restrictive. It wasn't worth running another 7 psi for 10 hp and 25 lbsft Tq so we dialed it back down to 21 psi and this it where it stays. More than satisfied.

What turbo are you using that only netted you 10 whp on a 7 psi increase? That's horrible and it must be way out of it's efficiency range.
