too bad, cause then you would of had the easy answer

ive got a stock turbo froma 2002 power stroke 7.3L. It would definately be an upgrade.i got some measurements if your serious

HomeMadeTurboz

It was a filled block, and had custom rods, pistons, head, ect... AND iirc it ran a sigma fuel pump and JD sticks as well. So yes unless he is willing to put $20K into it I stand by it being fragile.

If you really want to try an upgrade, an S300 57mm would be a good one, as would even a stock HX35-12cm. I think your truck falling on its face up high has far more to do with fuel, and timing, then it does turbo. The HX35.12 would spool quicker and moves enough air for ~300hp that is cool enough to drive. This depends as much on timing and driving style as anything though.

A powerstroke turbo won't work. Already looked into that idea. Due to it being a reverse rotation there's just no easy way (or room) to do it.

Also, the engine is not "fragile." It's running boost on top of 21.5:1 compression and that's where the problems come in, because if boost goes past 15 psi you seriously risk blowing the head gaskets, and that's not a job I particuarly want to do if I don't have to.

2nd, you can play with timing on a diesel, but I don't really know how to set it (it involves advancing or retarding the injector pump and I don't particularly want to screw it up)

3rd, as far as I have calculated the engine should be moving about 25 lb/min at 2500 rpm and 30 lb/min at 3000 RPM. Somewhere in that range.

And finally...Ford engines are fragile? right. How about leaving the brand-bashing BS out of this thread.

oh kayyyyyyyyyyyy!!!

So you just want more boost but you are scared to turn up the fuel or advance the timing?

1st) Brand bashing WTF are you talking about? I have built everything from VW, Ford, Chev, Cummins, to DT's, to JD's ect...

2nd) From what you just wrote I know you don't have a clue about diesels at all. How they make power, how they work ect... You should get a basic understanding before you mod anything. (Example: Unlike a gasoline engine where it is kept at a fairly fixed ~ 10:1-15:1 A/F ratio, therefore when you add boost you add power as you naturally add fuel. On a diesel A/F can run from 6:1 to over 100:1, Fuel makes power not air, so if all you do is add air, you don;t gain ANYTHING. This is why I said start with fuel and timing first, as that is where the power is to be found.

3rd) The CR has very little to do with how much boost it will hold, vw idi's run 23.5 CR and I have run 45psi+ on those.

4th) If you are afraid to change a HG, don't ---- with adding power.

5th) As far as you calculations imagine this... The stock turbo is right there.

6th) Get educated before you start running your mouth about what you think you know. Start here: www.thedieselstop.com

Finally if you ask for advice be prepared to accept what is said. Including in stock form the 7.3 and 6.9 (almost the same motor) idi's are fragile, and take extensive work and $$$ to make any sort of power.

Alrighty nevermind then.

I have plenty of a clue about how diesels "work." I know that you add fuel to make power.

I don't believe I was "running my mouth" about anything but whatever. **** off.
