Re: Most hp out of 7.3? Whats the max... 450hp?

Yeah 220,000 is quite a bit but not horrible. Depends on how the engine was taken care of too. Rebuilt kits vary so you'll have to search the internet but www.blackwidowdiesel.com (BBunting) sells a kit I think and many others sell long and short blocks.

Hey, you've really got your "stuff" together. Just think, for around $12k, you can install a 500-600hp Cummins. Add another $3800 and you get a beffy tranny to hold it. What would you rather have?

Re: Most hp out of 7.3? Whats the max... 450hp?

Yeah! Lots of people are pumping high HP and torque out of a 5.9 Cummins. It's good to be different sometimes.

You won't see 369 rwhp without injectors or aftermarket hpop with stock injectors. Good programming is the key, but 369 rwhp with stock injectors and hpop will not happen on #2 only.

I run stock HPOP and injectors and have dynoed my truck numerous times and have constantly seen 365 rwhp! Darn, 4 HP short of 369, dyno's must be lying again! ROFL [img]/ubbthreads/images/graemlins/biggrin.gif[/img] [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

I just want to say something about drivetrain loss.
A stock auto is 250 at the flywheel, they usually dyno 210-215, so lets say you lose 40hp through the drivetrain, that's 40/250 = 16% of what you started with...

[/ QUOTE ]

I do not know how Ford measures or rates horsepower, but 210 wheel HP versus 250 rated HP seems to pop up often enough to be accurate.

I just wanted to point out that the missing 40 horses might not be all "drivetrain" losses. Manufacturers have been known to measure engine horsepower with all the accessories off the engine (alternator, airconditioner, power-steering pump, etc...), even to the point of removing the fan and water pump. And the fan alone might account for 20 horses or so at redline.

Nice list, and pretty close to the parts and $$ I've added up myself.

I'd like to see a list like this made into a sticky post or something, for easy reference. One of the Dodge sites had a list like this once (maybe still do, but I forget which site). Makes it easy to see what it costs to play.

I'm glad that PSD bombing is finally getting mature enough that it is finally possible to make a list like this that people can generally agree with. [img]/ubbthreads/images/graemlins/grin.gif[/img]

There are good reasons to stick with the PSD ... <ul type="square">[*]You don't have to worry about changing the entire mechanical, electrical, and plumbing interface between the engine and the truck/accessories[*]Bragging rights (some Dodge owners are a little too snooty about the Cummins engine, as if it were actually a Dodge engine)[*]For moderate power increases, it's much more cost effective to stick with the PSD[*]The challenge of making a 7.3 PSD competitive with the newer common-rail rigs[*]You just like V8 engines better than inline sixes[*]You're afraid that you'll end up with a 5.9 that was actually once in a Dodge, and it will give your Ford cooties[*] (Insert your favorite reason here) __________________________________________________ ______[/list]
On the other hand, there are also good reasons to switch to a 5.9 Cummins ... or maybe a Navistar DT466 (commonly used in tractor pullers) ... <ul type="square">[*]At some level of power, it will likely be less expensive to switch to one of these engines[*]You may want the increased reliability of a well-built, non-electronic engine (especially if you've had an electronic component, like a CPS, die and leave your truck dead on the road)[*]You may want the inline-six engine configuration (e.g., to more easily fit sequential turbos, or additional accessories like air compressors or welders for off-road rigs)[*]You windowed your block and have to replace the engine anyway (this removes much of the cost advantage of sticking with the PSD)[*]You like the inline-six so much that you're willing to remove a perfectly good V8 just to have the six in your truck[*]You have money to burn and can't think of a better way to waste it[/list]
No matter what the individual reasons are, I wouldn't worry about it. We're not going to see a mass exodus of PSD owners willing to dump a perfectly good Navistar V8 just to swap to a 5.9.

you don't need to spend $2500 on injectors. you can run stock 530s (for less than 2500) and from what i understand (note: not what i know) you can push 450rwhp.
rods are about $1500-$2000 swap (what i've been quoted) unless you can do it yourself- so don't let the $475 price fool you.
I am pretty sure there are several 300+ rwhp trucks without a full tranny build as well... a TC would be good, however. I know gregrob is 300+rwhp with a stock trans, and there are others.

Re: Most hp out of 7.3? Whats the max... 450hp?

does that rod quote mean cost of good rods or stock forged with install? cuz install will cost about 2k if you have someone do it not including the cost of rods.

Re: Most hp out of 7.3? Whats the max... 450hp?

Those numbers were just a guestimation of what I would do (installing all the stuff myself). Rods are no big deal you just have to pull the engine is all. It's not right for everyone. And I was talking about bulletproofing the tranny and engine (you can cut back on some things I'm sure). I didn't know about cheaper injectors until I did some more searching. Thanks for the input!
