ok guys i want your opinion on this i got a rp performance main drive pulley and i got a midpipe on and i want to get rid of the airpump.Chris from rx7.com said that it would be wise to take of the main pulley and put the stock pulley back on and get the greddy pulley to remove the airpump since it comes with waterpump and alt pulley.
thanks for your help.

 

does anyone have pulleys...

 

why do you want the main pulley for??? just get the greddy pulley set. works great

 

that greddy set is just 2 pulleys correct alt and wtrpmp

 

I run the Unorthodox Racing single belt main pulley AND the Greddy WP and ALT pulleys. The only challenge is finding a belt that fits for that combination that I have.

I used a Goodyear 4060290 belt. THIS BELT HAS 6 RIBS. This means you need to cut one off with a pair of scissors. Not hard.

I think that Max Cooper's website also lists a 5 rib Gates brand belt that works.

There is some dimming of the lights at idle, but other than that I haven't noticed any downsides to running this setup.

I dunno if the RP and the Unorthodox pulleys are the same size, but you might have to get a little creative like I did

I spoke to chris at rx7.com and he said put the stock main drive pulley and put the 2 greddy pulleys one with the stock main drive pulley.

 

Just a Q for you guys with pullies... is there any effect on the A/C? Mine blows really hard and cold and I want it to stay that way, though I don't want to be tied to my air pump.

 

I took off my A/C.

I took of my Pettit crank pulley for the same reason, the belt barely touches the water pump pulley. I just bought my greddy pulley kit and will be installing it. I would have loved to run the stock pulley set, but i could not find a belt that would fit, i did find a 4 rib, but i wanted something to fit well.

 

I have pulley's. The Greddy Pulley set. That's the only one that will EVER go on my car.

 

I run the unortho main pulley and Greddy pulley set. There is plenty of contact with the Greddy water pump pulley. I also use a 4 rib belt with no problems.

Like Brian, I run the Unorthodox Racing Pulley, with the Greddy Pulley kit.
I removed my AC, Power Steering, and Airpump.
