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.

Wow, nice. That thing must pull pretty hard. Any engine management?

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.

Will it be worth my effort to install the Delta 1500s on stock motor with 14psi supercharger? Or should I just wait to put it on built motor with 20psi...

Cams will be on hand here shortly. Built motor is a year away....
