No, but if we calculate the fuel in the map etc. it was 400 whp on 1,25 bar boost.

On which engine was that?

On the 2.5 8v turbo engine.

Nice, that’s strong for sure. How was the spool up and transient response compared to the gt3071? Also, were you running stock exhaust manifold, out of curiosity? Thank you!

Gt3071 vs gtx3576, it wasn't very much difference in when they spooled, 2-300 rpm. I have no log to verify, but the 35 was more responsive above 6000.

The biggest differences in GT, GTX and no G35-900 is how little inner energy they need to make boost. 20 year of evolution.
