Does anyone know how many Static degrees of timing a 1/8" bump is???

 

Figure the math.
What is the radius of your timing mark from the center of the shaft?
PI R square. No Cornbread square, pie round.
Distance around divided by 360. 1/8 = .125.
A SWAG, but I'd say close to 1°.

 

I dont no about the 1degree How did you get that degree sine up there any way the more timing the smoother it runs on top

 

Dial gauge is 35 bucks and worth every penny....

 

I was going to say it depends on the internals of your pump. I've had a few trucks that the standard 1/8" on the pump flange took me from ~1.4mm to 2.0mm. Others have moved from 1.25mm to 1.5-ish with 1/8". Like IRoss said, a gauge is not expensive, and worth it to know EXACTLY where you are.

 

I did a 3/16" bump, by ear, and it wound up being around 2.1mm, so backed it off to 1.8mm and found much better lower end pickup...I beleive it is around 1 degree per mm....

 

definitely worth it having the gauge. I sure do miss the dynamic timing of the VE, but I can't whine about my new pump

 

The question of degrees of timing on the VE's has been asked online on various sites many, many times with no real good answer. I believe it is not possible at this point to determine a degree of timing with the VE like you see for the inline pumps. It is because the VE is in a constant variable state of timing depending on case pressure etc.
