Anyone have the specs. for the V8 supercharger? If I'm not mistaken we use the same TVS 2300 supercharger like everyone else does. Specifically I'm looking for:

Pulley ratio/diameter.
Supercharger drive ratio.
And any efficiency numbers you may have.

Thanks!

 

The V8 uses the Eaton TVS R1900 and the V6 uses the TVS R1320.

 

This may help:







The dashed lines are SC rpm and the contour lines are isentropic efficiencies.

 

On the R, stock upper pulley is 66mm, lower pulley is 152 mm, so SC speed is 2.3 times engine speed.


The smallest upper pulley that will fit is 60.5 mm, the largest lower pulley that will fit is 170mm.

 

Where were you 8 months ago when i had to do all this research myself?

 

Just taking delivery of the car.

 

Unhingd did you modify your upper or lower yet?

 

Yes. Upper was reduced from 62mm to 60.5mm (hardly worth doing). The 170mm lower (which I already have on hand) will go in shortly. I was hoping the short shifter would be available to install at the same time, but looking very unlikely now.
