I have a 60-1 upgraded CT with a 10 degree clip on the exhaust wheel. Like a couple guys already stated, I love the SUPER fast spool. I can break the tires loose all through 1st and half of 2nd and can get em to break loose from a roll, depending on how fast Im goin. Its crazy loud and intimidating. So loud, that Ive had several people tell me that it hurt their ears when I spooled up next to them in traffic. From what Ive read, since mine is clipped it actually spools a little slower than non-clipped ones, if so, thats insane because mine spools quick as hell. It makes great power, Ive made 371 RWHP on a terrible tune. It pulls hard all the way to the redline with ease. Ive been running the turbo HARD for about 3 years now with no probs as of yet. Ive always warmed it up before boosting and cooled it down properly, so Im sure that has helped. Overall, Id recommend it to those of you guys who are on a budget. I wasnt ready to spend 1-2 G's on a "real" turbo setup so I went with the upgraded CT. Its a cheap, fun, and easy upgrade.
