Hi all, planning an xud compound build, just wandered if anyone could advise as to the best way to build an 11mm pump for an xud. Am I best off fitting an 11mm head to the 9mm body, or starting off with an 11mm and modifying governor? If fitting 11mm head to 9mm pump, which camplate should I use?
Thanks, Jack
you use a standard xud9 Bosch pump the only parts you used the transit 11mm pump (normally this is the pump used for an 11mm head) is the head, plunger and fuel control sleeve.
use the cam plate, shim and delivery valves from the xud pump the transit injectors are of a totally different design and are not compatible. hence why would have to use the xud items.
do not be tempted to use the Cam plate from the transit it is for a direct injection engine.
For the gov mod use the xud item the transit one is longer

Definitely use the delivery valves from the transit, along with head, these flow literally 30hp more fuel...... use the govnor cradle from transit, all other bits from XUD.
Interesting build engineengineer, do you have a project thread? there are a few guys around the forum who have compounded the xud.
