What size belt do you guy run with the March 2 pully setup?

 

Is it the "power and amp" 2-pulley set, with the overdrive alternator pulley, of the "performance" set with an underdrive alternator pulley?

 

power and amp #4485 comes with the alt overdrive and the crank underdrive

performance #4050 i believe only comes with the crank pulley

I've heard good things about ASP underdrive pulleys.
They offer a haus that's about 34% crank and 15% alternator for the kit. Their site looks like a 5 year old designed it and it's very hard to navigate. I'm going to go for these boys soon.

AND i believe they issue the belts that are required also.

 

yes its the "power and amp" 2-pulley set

 

The belt size straight form mach performance they say. For the 4050 kit we recommend a 59.5 inch belt. For the kit 4485 we recommend a 59 inch belt.

 

good looking out
