Awesome numbers...but are you saying the turbo was pretty much out of steam at 1 bar? Great setup...1.06 AR on T4 Twin Scroll isn't shit really, bigger is better...love the powerband.
What was your base FP???
I think you would max out the turbo around 20-22psi...in the 600whp range...goes to show how absolutely awesome the F20 motor is...it take 30psi to make that power on a 4G63.

Base Fuel Pressure is right around stock...~45psi
Yes the F20/F22 motor flows very well. As we increased boost pressure, the top end of my graph was getting very choppy. Tuner said we were getting a lot of back pressure at higher boost levels (probably due to my 70mm exhaust). Could I swap my exhaust and hit 600...probably, but I absolutely love the way my exhaust sounds so no plans on switching that up anytime soon. Car has been down so much the last few years that it's time to drive it and enjoy!

You cannot run this turbo on this manifold with stock motor mounts, it will hit. I had to buy Innovative mounts to gain clearance (also had to fab a heat shield to protect the motor mount from the turbo heat.
Once you think you're in the clear, you realize that the compressor housing hits the side of the engine compartment. I had to clock the turbo and shave/grind a little of the housing away so it wouldn't hit.
Hope that doesn't steer you away, it's a great turbo!....and atleast you know now in advance

Very nice numbers. Was it a pain to fit that turbo on the ram horn? I have the the same manifold want to switch to gtx35r once my 6262 goes out.

I wonder if the smaller turbine wheel got in your way or the t3 flange. Housing is ginormous. Regardless power band is bad ass.
