Anyone running a 66-1 please sure your experience on it. Very curious to know what to expect out of it.

 

well if its anything like the 66mm we run on our Z..... small block chevy powered of course.... that and looking at the compressor maps, the turbo comes into efficiency around 20psi and doesn't leave until around 3bar..... its kind of a wierd turbo to be honest. I don't like it on the street, unless you have a large displacement motor... plus one that handles lots of boost

 

anyone else would like to share there insights

 

Anything using the TO4R/T67 compressor wheel would be a better choice at lower boost levels.
