idi?
Hi I am not by any means new to ftef. I have always and will always run fords. I am strongly looking at competition pulling and dragging. I really like to keep things simple and was wondering if anyone has really built up 7.3 idi and if they are capable of high horse power or am I wipping a dead horse. Please any good feedback would be greatly appreciated.

doubt it. the problem with the idis and all of the powerstrokes before the 6.4L is the lack of ability to flow enough fuel for high hp engines. truthfully find a 2nd gen 12v cummins from a dodge. those p pumps can pump like limitless fuel. it is possible to build up an idi/powerstroke, but it costs a ton

Best thing you can do for an IDI is turbo it. You can get a moose pump and moose injectors i believe. Open up the exhaust and make or buy some kind of ram air intake, and youll be in good shape.

No experience here sorry, but I have been tossing the idea around myself im looking for a 250 with a 6.9 to play around with but Im not to serious. Personally I really like the idea of a performance IDI just because of their simplicity reliability and the rarity.

Get on idi forum on here. And post similar. If your serious about this and have done that much all ready. U can push more fuel then these motors will handle with a modded DB2 pump. A stock size idi turbo is not gonna run it with that amount of fuel. Probally go to something like the first gen strokes had or larger. Lag wont be a huge issue if ur comp only.

I know of a guy in northern IL with a 6.9 in a 67 half ton that would run high 8's on the strip. Has so much work done it doesn't even look like a 6.9 anymore. But with alot of money it can be done.
