Like I already said... the X IS an evolution of the IX. It's like saying the VII wasn't an evolution of the VI (which is somewhat true, lol) or the IV wasn't an evolution of the III. It's a better all around car... there's no arguing that. There's no arguing that it's better on the track than a IX... anybody that's ran both at any kind of event will tell you this. Of course it's not as fast/quick as a XI on the drag strip, but that's a moot point since drag racing is NOT what the car was built for.

I'm glad your motor is still running strong...just be VERY careful.
This taken from Forced Performance's website:
Forced Performance Turbochargers: FP RED Turbocharger Evo IX
"The FP Red turbocharger for the EVOIX is the only stock format turbo capable of delivering 550+whp with some examples recording over 600whp. Typical installations of this turbo result in mid to upper 400's on pump gas and mid to upper 500's on race gas depending on ambient temperature and related mods to the car in question. Typical boost threshold is about 3700RPM with some cars spooling up slower or faster depending on camshaft selection and other variables.
The turbocharger should be operated at 22-24psi on pump gas and about 30-35psi spike dropping to 25-27psi by redline in race gas applications."
My cause for concern on this has stemmed from my conversations with Robert Young at Forced Performance. I am sponsored by Forced Performance with my STi and had considered the RED for my build before I had built internals. He strongly swayed me away from that as for both the EVO and STi with stock internals. Even with Cosworth internals, I upgraded my Green to the HTA Green and I run 100 octane plus meth!!!
I have seen 3 evo ix's go "Kaboom" in the last 3 months out here using the Red with stock internals (with race gas) pushing 30psi!
And as far as the Evo 7-9 vs X on track...i have driven them all on track...X is faster hands down.
