came across this article that states some supercharged toyota 100 series and V6 Holden Commodores came stock with M90 High Helix SC Rotors. Is this true and where can i find them. Click on this link Cruiser 100 Supercharger

 

It's actually not called a M90 High helix its called a TVS by Eaton TVS Roots-Type Superchargers
It's not fitted to the V6 commodores but to the HSV V8 commodores

There is a guy here in Australia fitting a TVS 1900 supercharger to his XJR6 am currently speaking with him he has made a plate up to adapt it to the XJR6 car

It actually moves 1900CC per rotation I.E. 115.94 cubic inches per rotation so slightly larger than the M112 s/c

He is fitting it as he got a brand new TVS S/C given to him from what I gather

Next time I am in Sydney I will be looking at what he has done he has also had custom pistons made and a ported and gas flowed head shot-peened rods with heavy con-rod bolts so a bit of money spent already

I am not sure if he is on this forum I would say so he knows a few of the guys

Very interesting project though

I am having headers made for him copying the set from my XJR6

 

wishful thinking. One day a pair of high helix eaton M90 rotors that will slide into the case will be invented.

 

This is an old thread, but did the project mentioned above ever come to fruition and work out?
