Stock motor on 93 octane pump gas @ 23 PSI, my car made 374.17 HP and 358.43 TQ.
After building the motor on 93 octane pump gas it made 391.27 HP and 369.45 TQ @ 26 PSI on Fynetune's dyno.
Lastly is my old race set-up that was a 50/50 mix of distilled water and M1 meth on my stock motor at a 29.5 PSI spike. It made 413.21 HP and 434.80 TQ.
My new race set-up with my built motor and meth are going to come soon. I hope to shatter the last meth numbers, but I'm already chocking the stock turbo out pretty damn bad..

I will also go for 400 HP on stock turbo on pump gas as well...

Later on I will add my dyno of Buschur stages 1-4 @ 22 PSI, I think it was like 320+HP and 302 or so TQ... I can't remember, but that was on CFT's mustang dyno... I thought of adding it to assist with this thread if you guys want to see it...
