Now running 14 psi supercharger with 93+water/meth on stock EJ253... trying to figure out how to go more. I am on the smallest pulley I can find so I need to rev higher to get more boost! Waiting to get on the dyno with the current setup.
I think it's maybe 300whp if I'm lucky, but will have it on the dyno soon . It uses the stock ECU re-flashed which works pretty well. It's not bad but because it's a centrifugal SC the power is all top end , a bit of a dog in the low end.
