LS3 Vette Procharger Dyno, 752hp/662trq
I finally got my Procharger on my Vette. I installed the same clutch at the same time so I was breaking it in for the past 2 weeks and doing some street tuning.
I did most of the tuning on the street with a wideband but the car was making good power and I couldn't hook on Invos, so I couldn't take it to redline.
Well after swapping out to a fresh set of plugs I strapped the car to the dyno for some final tuning.
First pull I pulled it to 5400RPMs and the car made 686hp.the AFR showed 14:1 but I had thought the dyno's wideband was fishy, so I swapped it out for a new 02. I added some fuel to compensate and sure enough the pull was dead rich. Shutting off at 6000 It made 721hp.
I took the fuel I added back out, set the timing at 14* peak and let it rip. AFR ended at 11.0:1 with the methanol active.. and the car made 752hp/662trq!!
To prolong the life of the shortblock, I decided that was enough for today.
Not bad for a D1 Procharger @ 10psi and some pump gas w/ meth!

And another dyno sheet for comparison's sake:
Since it's a little damp and humid as hell down in Houston, I can't get any traction whatsoever so I haven't gotten a chance to even enjoy the newfound power!
