[quattrorunner]

I have one. I like it but can't compare to anything as It's the first turbo I've had with this engine.
I have a 76 3.0turbo 930 engine. It spools, but not quite as fast as I expected. I have the euro heat exchangers and expect thats my issue but full boost of .8bar is realized by about 3200 rpm.
It does push very hard to 6000 rpm (sc cams).
