nice numbers! what's up with him having vehicle speed in the bottom instead of rpm? That might change the numbers a tad iirc. I bet she was screamin tho!

I was thinking same thing when I was down the road and I looked at my print out. The belt slipping would change the numbers. I think he messed the page up when he showed me the smoothing factor difference. Not sure though

Looks take care of that belt slip...and get that thing running at 100%...What part of Louisiana you in? I'm in Monroe area I have tvs @21psi I'm about to get it retuned for 22 degrees of timing.

I'm in Raceland-Lockport are close to houma. yes I ordered a belt yesterday lol. as long as it slips at 6300 i'll just shift before lol.

If you have belt slip then it's not a short enough belt. Your new belt should NOT be easy to install.

There's no need to fight a belt....get the adj whipple tensioner and quit sweating the belt fitment and sizing issue

Good numbers OP

lol funny story, the box from the belt I have on the car must have the wrong measurements on it. I went to napa and bought an 81-3/8, went i go home took belt off car it ended up being 81-1/4. so the one on car was actually smaller than one I bought lol.

napa is getting me an 80-1/8 today, which i think will be too small but I'll give it a try. the closes 80-3/4 was in tampa florida. i believe that is what i will need.

but I put old belt back on and no squeak lol...

 

[03cobrajc]

to be honest Tim, i have so many napa green belts that the belt on the car was probably in the wrong box to begin with on my part. lol:shrug:
