Anyone got the part# of the dual pulley from mitsubishi that works?

Thanks, Gonzz

P.S. Also anywhere i can get one..

 

Racing Beats has them, thats where I got mine. These are the part numbers.

Double Sheave Alternator Pulley - 11479 - $65
Double Sheave Main Drive Pulley - 11469 - $42

You can use these on all Rotary engines from like 74-92.

The configuration of both Underdrives the alt about 40%, and the water pump like 15.

Unless you rag on your car all the time, and I mean like redlining every gear all the time. The main drive pulley is not for you, your charging system will be messed up, and your cooling will be affected.

You could try an electric fan, but still if you drive city all the time, you will most likely overheat.

Its better to get one stock size if you are using on the street, The racing version such as Racing Beat sells underdrives the alt as peak revs would burn out the alt bearings and anyway they are not seeking that much electric power as on a street machine. The Canadian Racing is more appropriate and under half the price!

 

Let me give you a tip that works in a slightly different way... DISCLAIMER: I am a 2nd gen guy, and this works on 2nd gens. I don't know positively if everything is sized the same on a 1st gen or not.

You can use a LAWNMOWER belt, Part # 3L220 (220 mm long) around the eccentric shaft pulley and waterpump pulley. Some 2nd gen guys do this when they remove the airpump. It's a pain to put on of course... but you don't have to change ANY pulleys. CHEAP and effective.

 

I did the same thing that rx7_ragtop did on my 1st gen. I got the idea from pratche and rx7carl's rats nest removal. It was kinda hard to put on but I have no belt slippage at high revs. I got mine from O'Reilly Auto. They said the partnumber was on old Gates belt part number.
