I recently bought a low mile '86 T type, that has a TE 52 turbo with 009 injectors and ATR dual fuel pumps. I am not familiar with deciphering the flow graphs. Could you tell me at what point of boost this turbo starts to fall off on air flow. I have boost set at 18# for street. I want to think this turbo might handle up to 23# boost with racing gas if I were to take it to the strip.
In the parts box that came with this car was a spare yurbo with stock sized impellers. The inlet is a TE style and that impeller is more cylindrical compared to the stock impellor looking like a truncated cone in side view. Is this turbo any appreciable gain over the stock turbo ? Is this what Eastern Performance used to call a " CHEETAH" turbo ?
Thank you very much for your time !!

The 52 turbo should work well at 23psi. It will start to lose effeciency above 25psi. Above 20psi run good gas and keep an eye on knock! As far as the box turbo....you lost me.
 
I don't know about a 52 loosing efficiency above 25psi. I've never seen a compressor map for a 52. I can tell you from experience that a 52 will really wake up at 26-27psi. At 29-30 PSI holy $hit, Hang on!!
