I'm curious about the alternator pulley form rotary innovations.

I have a racing beat unit and I'm tired of having low voltage at idle with the lights on and my power converter on when I installed this unit. THis unit is an underdrive pulley.



Is the rotary innovation not a underdrive pulley, same as stock right? I'm curious about your opinion.

If the pulley you are considering is the same diameter as the std one it will behave like the std one

If it is bigger, it will underdrive, smaller will overdrive

Thanks Rob but that's the question I"m asking, if some has comperated the pulley to the stock one?

OIC! Sorry https://www.nopistons.com/forums/pub...O_DIR#>/11.gif

No it is not an underdrive pulley, it uses two of the stock belts. I have one on both of my rx-7's.

Is ok rob, Don't worry, be happy! :wave:



Did you have any voltage drop at idle, more than usual phinsup?

No, no change at all on either car. Just my belts stopped squealing at high rpm.

The pulley is a great investment. I love it, belt doesn't screech and its doesn't drop my amps even with stereo and sub on at idle.

same size as the stock pulley......great buy and cheap too!

Sounds like is sold. Is price just right. Now who wants to by my racing beat one. lol

Sell it on ebay.

i have one on my TII also. works great!

U do. didn't know about it.

I would love one of these, no slippage. But like vosko said, is not 20 bucks.

C

the pulley's? Yes they are only $20.00 from rotary innovations.

I'll be going back to belts. Gilmers look & sound cool, but cops are getting heavier all the time here, so I am going 'full stealth' this rebuild.

Plenty in STOCK!
