9mm vs 11mm pumps

[Dave]

true... but did u do this due to not being able to increase the dynamic advance any further? i would have thought that even with the static at standard with a well set up pump that the dynamic advance can be altered to do enough?

Yeh thats a good point, however the pumps dynamic advance system isnt capable of advancing anywhere near 6,000 in stock form, then when it is setup properly with cage pin and spring modifications the advance needs to be more exponential at those sorts of rpm's rather than the linear system thats used, which is why more power is made with abit of static tweaking aswell.

Off you trot and get 30* of dynamic timing from a stock Bosch VE then

Good luck!

Just FYI - 600hp Mercedes OM606s run with NO dynamic timing...
