That is amazing! Just so I know how big it is.. What's the flow rate of the compressor?
Will the rear housing fit on my garrett turbo ?

There are a couple of compressor options we are investigating...
The turbine housing will only fit on a VNT center-section.

The current test-mule compressor is very similar to a GT30r:

The size is close or the same to a gt3582.
Seems very interesting!

Talk about needing a strong clutch to hold that bottom end torque!

Haven't had any problems with it... we are also exploring ideas with a new design.

Yeah! The scary thing with Sid's build is where to stop...? He has made a ton of power through a stock-valved head - a 16valve head is going to make even more power. Then couple that with a faster spooling turbo that makes even more top-end power!

Where to stop? There is only progression!

Bottom end, clutch and drive-train better be right.

Out of curiosity, what is the inlet EGT at the tubine entrance? Have you measured this value during normal operation? From the Garrett site it reccomendations staying under 1050 C or 1922 F for their VNT's.
