While the 7.3 PSD is good to about 450-500 before dumping serious coin at it
^This is what I'm talking about.

Injection Pump 2000
Injectors 300
Turbo kit 2000- can be built much cheaper
fuel system 250
Studs 500
Intercooler 200
W/M 200?
Here is a recipe for a 450-500 horse idi, $5550 not 10k.

Dyno was 401hp without an intercooler, so pretty close. He also didn't have it timed exactly but there's no way of knowing if that would have netted 2 or 20hp. I grant that what it takes to be reliable at that level hasn't been perfected yet but obviously the average guy wouldn't take a wore out 7.3 re-ring it do the above bolt-ons and throw 50psi at it.

you proved my point, NOT 450-500hp. and not proven either

Ok, intercooler does NOT make power. It makes cooler air

And yes,I'll say it again, Unproven.

Saying you can build an IDI to 400+hp just because no one has done it YET, is like saying you can go to Mars, because no one has done it yet

LOL, Brad you're losing it.


....and cooler air makes power, as well as allows for more fuel in a diesel, which again makes more power.

From diesel power magazine:

500hp 7.3L Recipe
Although we’ve added many parts to our ’97 F-350 over the years, this is the list of modifications we used to break the 500hp mark.
John Wood Automotive Street Performance E4OD transmission
Unlimited Diesel Performance 238/80 hybrid injectors
DieselSite Adrenaline high-pressure oil pump
DieselSite CPR electric fuel system
Walbro lift pump
Irate Diesel Performance T4 turbo system
Fleece Performance S366 turbo
Spearco intercooler
ARP head studs
Comp Cams 910-16 valvesprings
Hamilton Cams pushrods
Gearhead Automotive Performance chip
MBRP 4-inch exhaust
K&N air intake
Total Investment $14,300
Subtract a generous 5k for the E4OD and its pretty darn close to 10k isn't it?

It sounds like a decent buy, I'd probably drive it as is for a little while. Make sure it doesn't have any big hidden issues before sinking money into lifts & mods. Just my 2 cents

And saying you absolutely CAN'T because it hasn't been done is like saying in 1968 that we can't get to the moon.

Intercooler makes cooler air, which intern allows for more fuel(which makes more power)

The intercooler itself does NOT make more power

And if the internals of the diesel engine would allow 1600* it would make even more power since THAT temp is where a diesel fuel is at optimal burning . but not too many things would allow those temps very long

I thoroughly enjoy the mechanical theory and physics behind engines making power, gas or diesel. At the same time, without taking sides I don't think it's possible to prove a negative in the course of the debate.

And in the end...

Every heat engine makes more power when the delta between the temps is higher.

So tell me again how an intercooler makes more power then?

No, you're just being argumentative for your own entertainment.
