Squeezing more power out of an already maxed out 11mm bosch pump

[Dave]

Delivery valves are a must, I used to use the Transit delivery valves gives heaps more fuel, you can actually grind the stock ones down too, just have a few spare incase you f*ck it.

Transit cradle, harsh Govmod, 11mm head, advajnce piston grind, you can modify the LDA swining arm inside to allow a further throw when the LDA drops, this will give you more on/off boost fuel. Grind out the inlet ports, add an extra 2 slices into the valve pump,

Have good free flowing fuel lines, and filter (probably best sack stock filter off).

There are heaps more mods you can do get at it with the grinder.

You must have a fairly heroic setup be be maxxed out with an 11mm pump, good one! Get an internal pump gauge on there so you can see what its doing - if your pump is clean it would be good to know what IPP is, and if it drops after a hard pull. Mine used to pull hard, then empty itself IPP die and have to play catch up with the fuel lines.
