If a person put a AAZ pump on a AHU tdi.. how far could they push the pump as far as torque output? If I wanted more Power, what would I have to do as far as swapping out parts to make more along the lines of 230lbs of torque?
I am doing reserch, into doing a MTDI and what pumps I can use..

It will be a laaaame weak engine with an AAZ pump. The AAZ pump has a smaller pump head than a TDI and won't even come close to stock TDI power.
You'd be MUCH better off using a Land Rover 200TDI or 300TDI pump. They bolt on with a little work, have an 11mm head (which is the "big" size for TDIs) and already have a suitable advance curve to run a TDI. Getting 230 ft-lbs will be reasonably easy with that pump, provided you have the other supporting mods you need (turbo/injectors).
-
so there is not way to turn the AAZ pump up or mod it easly to make that kind of power?
-
no its not designed for direct injection it can not create enough injection pressure to properly run a tdi.
-
It's more a matter of fuel quantity than pressure. Regardless, the combination of the 9mm plunger, control collar lever assembly, accel lever offset, inadequate dynamic advance, etc... all combine to make for a poor mTDI pump.
-
With an unmodified pump the setup will return very little power and good mpg.
-
i have decited to get a pump made.. as i need to make over 200lbs of torque for the TDI to work.
-
Sounds like a good plan. The Rover pumps can often be had somewhat cheaply but if you have a definite power goal and can afford a custom pump that will be a good way to go.
