ok so this is my first post cause normally i search and find my answers but cant seem to find anything to my inquirery. a little back info i actually own a 240 not a rx7, but my friend owns 2 and we are just about to turn over his s5 in a s4 car. anyways on to the big question, i have seen pictures in magazines, and few other places of people running, the big 3in supercharger pulleys for their crank, alt, and water pump pulley. i looked at the pulleys and it almost looks like they could line up with the stock mounts, or do you have to re-drill them. any help would be great, thanks remington

They are Gilmer drive pulleys and are available from several vendors.

Really they don't offer any advantage over the v-belts in normal use. And the constant whine is often louder then the engine and very annoying to many people.

ok thanks for your help, id imagine they wouldnt offer much, but they look kinda cool lol. the whine is tolerable, i guess it just depends on how hard core you are, its just like any thing else some people cant handle a welded rear end, so i guess it relative lol. but again thanks for your help

I'm probably harder core then 99.9% of people on this site and I can't stand the noise. When the belt system is louder then the engine, it constantly sounds like a bad alternator bearing...

ok thanks, knowing that your "hard core" is assuring thanks.
