I know a lot of us JRSC guys having or had problems with our belts and pulleys and a lot of time we hijacking other threads because of it, so I thought it was a good idea to start up on a thread just about jrsc belts and pulleys. The thread is not only for current jrsc peeps but also for the newbies as well so they won't get us frustrated asking the same question over and over again.

I'll start off with one question, I read around and found a member who is using a goodyear 070775 belt which is 7 rib and 77.5 inches long. I tried a dayco belt that was 77.5 long and it wasn't even anywhere close to fitting onto the 3.4 pulley. The dayco 78.9 belt fit extremely well for the purpose. What I want to know is that anyone else tried the goodyear 77.5 long on a 3.4 pulley or is it because different makers make belt a little bit different in length.

Go nine psi and make sure the belt is tight. Looks like your picture they are a little loose. You get buildup on the belt if it loose. My belts are smooth and clean (well not literally) but you get what I mean.
Sonny are you on K20A? or K20A2?

If K20A How'd you lower your compression? I wanna lower mine 2 11:0 instead of 11:5 Im at..Cause I wanna push 9PSI.

and How do you tighen the belt? with out taking out the AC Pulley LOL
Son-U think I should be cool w/ 9PSI on 11:5:1?

People are telling me to lower compression..and some are telling me its ok, as long as my tuner is good. Which he is..Im on the Hondata K Pro.
