Kingpin-2

Well I put on my new parts yesterday. I have a 2011 gt500. We installed a new upper pulley, cold air intake, heat exchanger, cooling tanks and a tune by John Lund. It made 601whp and 575tq
Does that sound right about what it should make

Sounds great..I am wondering what your max. boost PSI number is?

Kingpin-2

It is making 14 psi. Their is still a few more things that will be going on later.

My 08 is making 14 also with the pulley change and high flow plenium...I was curious if the 11's were different...

Kingpin-2

What kind power is yours making

Lifter583

Ran 520 rwhp with an air density of .0679 and then another time 547 with a .0749 AD on a Dynojet dyno...your cooling ability will help a lot...after the air running through the blower reaches 130 degrees..starts to pull spark...I am wondering what got you to 600...

Nice numbers for sure... Those 11 are nasty with power... Mine only made 547rwhp and 544 torque.. With my future upgrade in 3-4 weeks I'm shooting for 650++ rwhp.. Keep it safe and have fun with your power

Kingpin-2

I don't no but I know the heat exchanger really helps out a lot. Plus it put down 530rwhp bone stock on the dyno

What brand name of Dyno was it run on?

Kingpin-2

It is Dyno dynamics it's twin load bearing Dyno
It's the best Dyno we Have here that's where everyone takes their car here to be truly tuned.
