Was wondering what kind of power people have been making with this turbo, have see a few posts that are years old, but wanted to see if anyone else would tune in. Posting after having my car tuned yesterday with exciting results 800whp and 550tq off this turbo.

 

Accurate dynos read about 745whp. Forgiving dynos read about 800whp.

Those are the limits for that turbo, mainly for du the limitation of compressor wheel, not exhaust wheel and shaft. This turbo had been on H-T for almost 10 years.
