What size is that impeller? 56/82?
Reaching 475hp with that 6cm^2 hotside?
I'd say 430-450hp on pump gas. But this thing gives full boost only 100 RPM's later than a RS2 turbo, and makes 80 more horsepower.
Compare that to to a K26/K27, which spools 300 rpm later and makes 70 more, and it is apparent why this thing rocks.
This is very close to a GT3071R/0.63. It's less like an on-off switch, and 100rpm later full boost, but it does not run as hot to redline.
I like the fact that it can be rebuilt easily and cheaply. I would not want to fit a bigger hotside on this HX35 though, this is perfect for a car with stock rods.
