Rick,

I put in your numbers at the TCI site and it looks like 15.241% slippage if i put everything in right.Try it also and see if you come up with the same thing.

Later Mark.

That's way too much IMO, 8" has no place in there.

I agree Jon,I finally listened to the video last nite that Sooz took from the stands at half track and it slipped all the way through. I will order a new 9.5 as soon as my RC budget builds up

Same Problem here, My 8" is at 28%..... . RC budget is low here this year too, No O freakin' T at work.

also what kind of rpm drop on the shift?

MINE COMES OUT TO -45% what im i doing wrong

X2, that's exactly what I got as well. Our 8" Chance converter had 5%.......

I MUST JUST HAVE A BAD AZZ CONVERTOR

..or you rpm number is wrong, hard to read a tach at the speed...................this is where a playback type is very usefull.
