Oh yeah... I LOVE my 67. I am SO glad I didn't go with a smaller turbo (was considering a TE62). I've only had one serious track day with it, so I still have plenty of tuning to do... but I made several 11.0x runs at 20psi (race timing & race gas). I didn't want to go home without that 10 second run, so with a heat soaked motor and 24psi it went 10.97 @ 120mph.
I can't wait to get to the track again and see what it'll do at that boost level on a cool motor
Also, I have no problems spooling the turbo. In fact, I've even been thinking what it would be like with a .85 exhaust housing on it?? Might be fun!
