I'm using the unorthodox underdrive pully.

 

humm i'd say the unorthodox has the same outer diameter then all underdrive pulley
but could you measure it just to be sure?
so far obx sytem, aos all use the same outer diameter, but in you case since i've never worked with those i'd like a double check ;-)

 

It's 4 1/2 inches

 

I'll take one if it will work with my Beta 2 engine!!

 

how are the brackets coming along Denisst99?

 

i made a few, but forgot to order smaller belts for you guys with underdrive pulleys
should be getting them in the beginning of the week
so everything should be allright ;-)

Dm,
i'll be able to make them work for the beta2, just 2-3 small things to change,nothing major

 

sweet!

 

i forgot to update the topic....

founda good matching bet for the ones who are running underdrive pulleys
and comfirmed the fit with various underdrive pulleys, looks ike we got a kit working for everyone!
