TDR Supercharger Nose Pulleys
How Much Boost will I gain over my current pulley setup?

For each 2.5mm reduction in pulley size, we gain approximate 1psi of additional boost.

For example:  If you have a 70mm pulley and installed the TDR-PUL4-65, you would see about 2psi increase. And 3psi for the 62.5mm pulley over the 70mm.
For increased boosted application above 7-8psi, install the TDR Intercooler kit for the M45/MP62.  As the supercharger boost increases so does the intake air temperature.  By installing the TDR air-to-air intercooler, intake temperatures are dramatically reduced.  Read more about the TDR Intercooler here.

Cone Style Pulley

 If you have the older style cone-shaped pulley, (see photo at left) the TDR Supercharger Pulleys will not work with your application. Our TDR Crank Overlay Pulley is your only option for added boost.
