I’ve owned two 7.3L’s and two 6.0L’s The last 7.3L I just traded in on an 07 6.0L and it had 180K with nothing more than oil and coolant changes. My 03 6.0L had over 80K with many mods and no problems. If I could balance a 7.3 to turn the RPMs and turn the boost up to 40psi I think it would kick @$$. I smoke my 38” tires shifting into second on my 07.

 

Where is gale banks?? LOL

LBZ's with light mods (turbo and twin fuellers) are putting down 700rwhp.

Built max's are over 1000rwhp 2000lbft on #2.

Bring on the 7.3.

I have a friend that has a built 7.3 that is well into 650rwhp range. It needs some good computer tuning. Is there EFI Live for a ford?

 

actually nastygirl is at 1980 ft lbs i believe... so no dmax has broken 2k tq yet... no there is not efi live for fords, i think that's the main reason we're so far behind

 

um I hate to burst it, but they have more they haven't shown. it is reserved for merchants. but ya no "posted numbers."

If ford have EFI live, it would make would give them 100hp more than they have now at every level per mod (if that makes sence).....whether the motor holds it is all would be the question.

 

oh yeah i know that, but they still haven't done it officially there is no dmax over 2k ft lbs, BUT there is a dmax that can achieve that, it's just a matter of time and not blowing fluids everywhere (i forget what they blew during that 1004 hp run, intercooler hose or something?)

 

oh ya, it blows everything... I expect a show. On that same note, Farmboystoy.....roger zeedyke lives 5 miles from me. wow is that a ride, he has blown about eveything on that also....including blowing the exhaust clamps apart. It is getting rediculous.

 

Kinda redefines the term redneck, don't it.

You honestly think a 2 valve head can flow as much as a modern 4 valve head??



Honest question to all the people living in the past who want a new 7.3.

Wouldn't an EPA legal 7.3 have essentially the same electronics/fuel delivery etc... as the 6.0/6.4???

Isn't the above mentioned electronics the MAIN problems with the current PSD's??


Enquiring minds NEED to know!!

 

cough 12v cummins... your point makes absolutely no sense

 

Don't worry DOHC, just chalk it up to the Mack truck syndrom. Ford released the 7.3 for the same reason Mack started building trucks, so any idiot could have/drive one. He forgets the 12V cummins has not been EPA compliant for years, and as of this year the 5.9L version is dead all together. Were not talking HP/TQ out of what was, were talking HP/TQ out of what is available now. Besides that, wasn't this thread about the Duracrap vs. the 6.0?

 

Not withstanding mrxlh's spot on post, school me on the difference.

Is the 12v making more peak power because the head is better/more efficent? Or does the non-EPA mandated fuel systems have ANYTHING to do with it??

I've been reading on some common rail 24V motors making as much peak power but with infinitely more drivability.


So my point (which was really a question) still stands:

Would the 7.3 having to basically run the same electronics/fuel system as current motors have a snowballs chance in hell of making the same numbers as a 6.0/6.4 or even a Duramax for that matter???

Do you really think if it would have been that easy, Ford/Navistar would have just refined the 7.3??


I assure you these are legit questions, I'm not trying to start an argument.

 

well your original statement about a 2 valve vs 4 valve didn't mention EPA regulations so i didn't include those in the discussion (not an arguement, a discussion) and sorry about being so mean when i wrote that post, i was really angry that day at lots of stuff and had to vent a lil

 

I'll offer anyone here who is a self proclaimed expert this challenge. You show me flow numbers off a 2 valve head that exceed a 4 valve head from an accredated flow bench/operator and I'll kiss your *** and give you 30 minutes to draw a crowd. As bad as I hate to use them as a reference, does a 3valve triton ring any bells?

 

It's cool...........but I honestly am perplexed when people say, "bring back the 7.3."

Having to meet today's regs, I believe the 7.3 could not touch a "modern" motor.
