GZE pulleys NEW question

[bozu]

A bigger crank pulley will increase the revs of the supercharger pulley, add to that a smaller supercharger pulley and the supercharger will spin even faster.

But as Lauren said the supercharger will generate more heat and become less efficient as they weren't designed for high rpm. (that's why a supercharger delivers more down low and less in the higher rpm's)

Again as Lauren said you'll need some sort of cooling to keep air temp's down and get cooler and thus denser air in the engine. Denser air = more power with same boost level.

Those are the basic's.

Now If you want to be really precise you would need to determine/look up the the diameters of the stock pulleys as these will give you a ratio. If you then determine the new ratio's with only the crank, only supercharger or both pulley you can determine how fast the supercharger will spin with either set-up. If you can then find some sort of efficiency graph of the supercharger you can see how efficient it will be at certain rpm's.

Simple option is just to look at other people's set-up, see what they're using, what power they're making, with or without intercooler and take into account any other mods they've done. Quick google: http://www.twincam.org/topic/15515-what-...what-mods/

I can't give you advice what to do as I've got a turbo on my 4agze and haven't got any experience with the supercharger but if you keep the boost below 14psi the motor should be fine (if it's a good motor from the start). Keep in mind though that by increasing power you also increase the stresses on the rest of the drivetrain...

Just my 2 cents.
