VE pump timing advance
VE pump timing advance
Yesterday I finished up a device that allows me to accurately measure injection pump timing advance on the bench. The test mule was an intercooled first gen "205" pump.
Anyway, the stock pump only allows 9 degrees advance at the crankshaft!





The maximum timing available from a VE is supposedly 24 degrees, But appears to be 34 degrees with a hack on the timing piston. For those who don't know those are numbers that the p7100, idle surge, sled puller crowd talk about.
No wonder we're advancing pumps to the head in search of top end.
Just thought you might like to know.

so you cut a bit off of the timming piston, like 2mm's?
and did you have to modify the case to let the conecting pin go farther or is there enough room,
I really should get an indicator setup, anyone know where I can get the adapter?

9* advance?
Is this the amount of mechanical advance in the pump?
im assuming that the 24* is the base timing + mechanical advance?
