here's the setup

02 rsx-s

stock crank pulley
comptech supercharger
comptech auto tensioner

pulley boys 3.0 inch pulley

makes about 10 psi...I'm running a k070776 belt that I was running before I installed the auto tensioner...before the auto tensioner install, the belt would slip in the higher rpms and higher boost levels (usually past 6psi)...now that the auto tensioner has been installed the belt screams at idle but holds/doesn't slip and makes 10 psi all the way to redline...a quick shot of belt dressing quiets it up at idle for about 30-60 seconds but then it comes right back...I've double checked all my pulleys (they are all tight) tried adjusting the belt a few different ways (pre tensioner maxed out, half way, and all the way in) to no avail...

long story short...anyone running this setup have a belt part number I can try or has anyone ever run into this before?

 

Who's belt are you running? Different belts have different rubber compounds....I like goodyear and gates....daytons suck.....

your belt is k070776.....this means it is a seven rib by 77.6 inches long....ask a shop for the next shortest size.

 

take a string and wrap it around. Tie it off... measure it up

 

I believe it is a good year belt, and I had planned on grabbing the next smaller sized belt, I was just wondering if any one had a belt that they were using that worked well...because just looking around on different forums I've got a lot of different answers as to which belt to run, and pulley boys has no recommendation for their pulley, and comptech's smallest pulley is 3.15" so I was just trying to avoid having to order 3 belts tomorrow morning

 

Ok set up has changed... Again. It is now...
--Comptech supercharger with stage 1 boost pulley (3.6)
--Comptech auto belt tensioner
--K24 crank pulley

Any idea as to what size belt I should run?
