I have been in discussions with NonStop Tuning regarding the prospective pulley products they will be releasing for the TRD supercharged tCs and they are interested in knowing what we would prefer. Which product do you want the most?

Supercharger Overdrive Pulley--this would swap out at the opposite side from the snail, and is the pulley driven by the crank. An overdrive pulley here would be smaller than stock and weigh less, but installation would require breaking the warranty seal. The only part of the car being updriven would be the supercharger.

Solid Crank Overdrive Pulley--this would be a direct swap for the stock harmonic damper, but would have a larger overall diameter (~10% overdrive) and weigh less than stock. Everything driven by the crank will be updriven. This won't affect the warranty of the supercharger (I am unsure for the rest of the drivetrain).

They and myself will be watching your responses to this thread carefully; please post any comments you can regarding your choice, if you could, besides voting on the poll as well.

Thank you!

Are there any serious negative effects to overdriving the other accessories (a/c, power steering, alternator) slightly?

 

supercharger pulley becasue the crank pulley will not retain the stock harmonic balancer which raises some concerns with me and heavy vibrations in the crank.


but thats just my .02

 

at a 10%, or similar overdrive, there would be no negative effects to any of the accessories, just more boost

 

This is the same feeling I have, and the reason why I put in the, "Other," option. I expressed my desire for an overdrive harmonic damper, but so far they have indicated no desire to produce such a product (also, it would be fairly expensive, more than twice the price of solid pulley options).
