INFO : R35 GT-R turbo - Get to know your turbocharger

Today, my mission was to weigh things, and to take a good look at the turbochargers. We pulled the outlet off one turbo, and the inlet of another. We wanted to see what the potential was for this IHI turbo. Some rumors were that it was good for 700 whp.

Compressor wheel

There is a step in there. This measurement was just to help eyeball the inducer diameter.

The exhaust wheel exducer is pretty small.

The wastegate puck is pretty large.

Another picture just so we can eyeball the exducer diameter.

Real similar to the size of the "special Nismo" turbos we had on the racecar for a while. The compressor blade design is interesting. Its also interesting how much power the car makes at 11-12 psi of boost that it runs. On paper, the stock turbos look like they are good for about 600 hp, however we are seeing about 520 hp at the engine at 11-12 psi. The size of the wastegate is also something to consider. Its large, and the exhaust wheel is small.
