Nice this is perfect. I can cruise around town and just shift around 3500 RPMs to keep things low key. Then when feeling saucy I can mash on it and take it up to 7000!
If you had ran against the Mad Scientist...you would have gotten an idea the power of the GT30. Did you see how fast he pulled away from the GTR
.....It was not even close!!!! You ran against the GTR.....It was a drivers race!!!Get the GT30

I plan on taking a ride up to Rancho Cucamonga on Saturday to see GTM's facilities. I come to Cali occasionally on business and would love to see their operation, especially since I'm definitely going with their Stage 3 kit!
Those GT30's are sounding better and better!

The Mad Scientist lives in my neck of the woods

Which GT30's did u have on XKR?
GT30 will not take you to 1000whp. The GT35 twin will, but it will be a dog at just 450whp, IMHO. Very laggy. That is a big dawg turbo setup, and very much a top end turbo.
There is no turbo that will be fun and responsive at 450whp, and still provide airflow to 1000whp.

I've decided on the GTM Stage 3 (Garrett GT3071R .64 A/R, .800 BAR @ 11.6psi) twin turbo kit for my initial "boost fix"! I'm building out my internals and supporting mods so I can easily upgrade to an S5 or S6 down the road...
Thanks again everyone for all of your help and guidance.

ya running 4 wastegates would be sweet! But i wonder if this would let you run a gt42 or something that much bigger and still have decent streetability.
I gotta do some more research on who this guy is. If he's an E85er, he's got to be running a ProEFI setup
