    Modify 7.3 idi vs cummins swap

    IDI! Even an na 7.3 will make that power with just a few modifications, you build an idit youll already have a turbo kit to start with and can reliably run more power than the na 7.3. Studs, turbo upgrade, 110 or 130 pump and youll be there with a 7.3 IDI. Price out the parts just to swap the...

    HP/Torque- When things start breaking...

    6.9s: Head gaskets are the first limitation, 8-10 psi without studs is doable, they have held 15-18 psi without studs but will blow at that level. Studded the clamping force should have them good up to 30 psi without going to a 625 hardware. Bottom end is just at strong as the na 7.3 parts. All...

    7.3 pump in a 6.9

    There’s more of a difference between the 6.9 calibration than the 7.3 and 7.3t calibrations for fueling. 6.9 runs smaller plungers and fill ports, you’re probably over fueling slightly, if you don’t have a pyro I would recommend getting one.

    Fuel leak on injector nut

    Either the injector threads are cross threaded or the nut/line is cracked, pull the nut off and get some pictures of the inside flare and threads on the top of the injector

    Building a better db2

    This is 400cc running through a stock injector, (.5mm O/P) 1700 pop. Itll be running with a set of my stage ones on the engine so itll likely pick up some more fueling with the higher flowing nozzles.

    Need site help

    @snicklas would know more on this but I believe the site certificate expired Sunday and it didn’t come back online till Monday night, google is probably still catching up and not showing it on search results everywhere yet.

    Building a better db2

    This ones from awhile ago, waiting on a billet driveshaft to push it further. Max effort .370, lots of EDM work. 400cc at peak, 210cc at hp peak, should be good for 500+hp out of a fairly common head. I have five .450 rotors on the way for a special project, good stuff to come. I believe this...

    Which turbo is preferred?

    You’ve got two non gated turbos there, an 088 and a banks first gen, arguably very similar turbos with the parts being better built IMO because of the antiquated carbon style seals the early banks turbos came with, but all that can be updated to a factory turbo style cartridge and step gap rings...

    blakpete91 88 F-250 IDI Build thread

    Brakes are flushed and bled, and boy even with no power assist from the engine they will stop a 9k lbs forklift in its tracks with ease, stoked on that since the brake performance was a little lackluster despite the four wheel brakes, going to the larger master sure helped. Today I’ve been...

    Some more progress, acquired 4x4 crossmember and transfer case shifter linkage for the truck, and stumbled across a spare skid plate cover I forgot I had that ended up working perfect as well. Got em cleaned up and painted chassis black, and got the 20 micron steel serviceable prefilter...

    Hypermax Smoke Puffer Limiter

    Thanks David, always pushing the envelope with these love what I do. Saw 430cc out of a two plunger today, never thought I’d see that.

    Hypermax Smoke Puffer Limiter

    Better off spending that money towards a pump designed with a flat fuel curve.

    Because winter's coming and (and there's no forum for other idi fords)

    Let me back and explain that further, lets establish a few things. -Housing pressure being zero advances the pump. How? Housing pressure and transfer pressure are basically acting against each other. When you have a worn out pump that wont hot start that is because the tolerances in the head or...

    Because winter's coming and (and there's no forum for other idi fords)

    Yes we have a mechanical advance, it’s the arm on the side of the pump actuated by the face cam on the throttle shaft. Return is almost nothing at cranking, timing will change with throttle position even at cranking, I see this first hand daily running the stand. Engine will start about the same...

    New champion radiator installed, now ready to run charge piping and set a final location for the battery tray. This champion rad seemed nice and straight, no weird bends in the cores like others have reported recently. Good looking cooling stack through that brick grille.
