just an fyi, you did get the correct length belt. The 112.5" belt is used for various pulley sizes. Now, the real indication of a properly sized belt is the amount of open distance on the tensioner pulley, should be around 1", if this is what you got, you'll be just fine.

 

Great, Thats what I get for listening to NakedAV and go bashing a Mod in the head. I'm ruined. A real pile of

 

Gonna check it. Kinda what I thought. Just didn't know the distance. Thanks!

 

if you want all the data on that belt look here , NakedAV was also correct saying 112", just forgot the "effective", as belts sizes are generally expressed in outside circ.

 

Grippy and Naked AV

I'm now officially a post *****!

 

Noticed a little bit of belt dust on the pulley and the blower today while cleaning the truck. Ran her hard at the track Saturday, didn't notice any boost drop (not that I watch it like a hawk while running) and the times were consistent. Hopefully just belt break in...

 

I just installed a new cam and had a loss of 2-3 lbs. of boost as well just like KySilverado. I went with a Comp 220/226 .581/.585 on XER lobes. So has anyone ever decided if this was because of too much overlap or because of flowing a lot more air, and less restriction was measured by the boost gauge? Or maybe a bit of both?

 

Now you didn’t give all the spec’s, but chances are the overlap is bleeding off some of the boost and oh by the way, great way to dig up a five year old thread (just FWY).

 

Nostalgia....What's the LSA on the cam?

 

Wow, holy old thread batman.

Ummm... I think then it was the 5.3 with a 114 LSA.
