I took my Yukon Denali to the dyno today and I made 412rwhp and 464 lbstq this time on the dynojet. I'm running 7psi. Its intercooled, with jba headers and corsa exhaust. I should have my new pulley this week and I am hoping to get around 10-12psi with it. These numbers were also with my 24" wheels. Any guesses on how much more power I will get out of my setup with more boost?

 

Very nice. Please keep us updated.

 

I redynoed this week with a new 4l80e lvl5 instead of my olf 4l65e flt lvl5. I also rasied the boost to 10.5 and I dynoed about 400whp and 425trq on a mustang dyno. Thats about 445-450whp and 470trq. on a dynoject. Im also only running up to 5200rpm. I need to get bigger injectors and a new fuel pump.

 

What size pulley on your whipple?
Is your setup 2 belt or one belt?

 

Its a two belt system. I just had a 7.5" crank pulley for the blower installed. This took my boost from 7.5psi to 10.5psi. I forget what the blower pulley is though.
