I changed the idler pully location to give more belt wrap, recently, haven't got it tuned yet so don't know if it will help much or not. It's also the smaller 1.6? non blowzilla unit.
there are different length snouts on various different other brand applications, personally to try to find and then make it all work correctly, you are better off just going with a different blower for intercooling etc. IMO.
I think someone in Texas had a separate belt set up done on a KB, not sure it ever went into the truck, but I did see pictures of the motor all done on an engine stand.
Seems had a screen name KBzilla maybee or something, was a popular guy from before I joined, then dropped off, or got banned??? don't know.
