My friend runs a vortech charger at 8.7 psi with stock injectors and piggyback with HUGE inter cooler... producing 240 RWHP!!!! Its been running for that for about 140 000km with NO issues whatsoever... It runs stock compression as well....
The inter cooler makes a HUGE difference to get the temps down...
I prefer the roots charger as the centrifugal ones has a turbo like lag...

This is my build....
Hope to crank it in the next 2 months...

We have done one for a guy who tows a big caravan, used stock ECU & injectors, added a 7th injector and controller, boost 7.5psi and 245hp on our dyno on 33" rubber. Intake temps were up, an intercooler would make a big difference and probably some more hp as well. It goes hard with no load!
