realistically makin 800hp non - nitrous 7.3
 

Now I know without nitrous this is almost impossible without doing a P-pump conversion or a CR (if beans or hypermax have put into production yet). But i was wondering if theres another way with the HPOP. Say money insnt an issue (it is but this isnt going to be an over night build ether) now it is a daily driver also and id like to keep it that way as well. Any thoughts? or is 500- 600 the limit. Now i know i dont need 800 hp but its just what i would like to see it happen

If Money is an issue, I wouldn't even think 800hp...

man im not a stroker guy but you almost NEVER hear of a 800 HP powerstroke and it would be about impossible to keep an engine that is so on the edge road worthy, it would be a quirky S.O.B to drive. if money doesnt matter build what you want but in all practicallity your wasting good money on a poor project. my .02

There are a few out there... The problem is the HEUI Fuel injection system that the 7.3 uses...

Turbo 2332 why would it be quirky? There's plenty of cummins guys thay drive 1000hp rigs as DD's. I know money is the factor like it is in any circumstances but say it wasnt can the heui and Hpop pump handle it or is a p pump or cr modification the only way? I love my 444 but really am looking into a 12 valve just because of its easy horse power capabilities but as a last resort to finding a way to keep it i posted here

If money wasnt an option and you had an unlimited budget, you cant close but it will be hard. You would need to do extensive block and head work to make sure everything stays together. Casserdy can make you custom injectors for whatever you want and the gen3 pump from swamps willl be more than enough to supply those injectors, and tuning is as simple as getting ahold of dp tuners. If I had the money thats what i would do

99xlstroker- what do you mean by extensive head work? I know studs and fire-ringed head but do you mean more things than that? balanced and so on? I mean i hate beating a dead horse and all but what makes the 5.9l so much more reliable than the 7.3l? I've read articles and spoken to guys with a stock bottom end pushin 700hp -800hp with no gridle. what makes our block so much weaker? (if it is weaker) :humm: is all this feasible for $10,00 obviously not including tranny or turbos? but just the fueling aspect?

quirky meaning tricky to drive. an engine cant be built for everything. so decide what you want. if you want all out power bar none then all but mark off driving it on the road. power will be on or off at these numbers so all of your drive line will suffer. power wont come on where it needs to come on for a street aplication. in my honest opinion 500 HP is about as far as you SHOULD go if you drive your truck on the road often. it will be managable, CRUSH most everything stop light to stop light and still be resonably reliable.

as far as the head work. monster valves and porting, compression ratio will most likely have to be fiddled with to accomadate the extreme amout of boost you would be pushing as well. the rods on the 5.9L are monsters and can handle way more power then a fords.

Thanks for all insight guys come Christmas hopefully ill have the money for what i still cant decide to do :tttt:

figure out what you want the truck to do. then figure out if you need a play truck and a DD truck!!! LOL lets us know if you have any other questions good luck

Well I don't need a play truck I can get in trouble on my own but hey if you go out go all out right :bat: lol but thanks guys and im sure ill have plenty more quesrion so don't go anywhere Hah

Your not going to DD an 800hp PSD without running into issues now and then.

Your looking at a large HPO system, 600/400 injectors, VERY large single or compound turbos, all the bottom end work you can come up with, and possibly a mild fill on the block.

the bottom end on our 7.3l that weak where you would have to fill the block to an extent? how about cryo treatment? Thanks for the info. :argh:

All of it. It would be nearly impossible to DD an 800hp 7.3. Not saying it can't be built, but to DD it... mmm probably not.

There are probably a lot of cummins guys who think they DD 1000hp trucks, but probably realistically very few. I don't think any of the cummins in diesel power recently have been at that power level and drive on the same settings. It's just not realistic and serves no purpose. 800hp on the street would be downright dangerous.

There are 6.0's making 800+ on fuel with stock HPOP's BTW :tttt: In fact there's a few over 1000 (spray of course) and even one that's about at the 1200rwhp (lots of spray of course) mark on a stock HPOP. No 7.3's doing that.

Its not that there weak, the dodge guys dont tell you but they do the same damn thing.

Cryo will not do much if anything at the 800-1000hp without a filled block and billet rods and a girdle...

Well thanks again for the insight fellas! I learned a lot!

what do you mean filled block?

the block is filled solid to help with cracking. so cooling efficiencies go down because less antifreeze is in the system and around components.

ah, yeah they do fail to mention that i suppose. Just for sake of argument though how about "the prince of power" i was reading an argument and its a 1200hp 12 valve with over 10,000 street driven miles on the motor, he even sees 100 pounds of boost on the street and brings it down to 80psi when he drags...:humm: with a over 10,000 miles on a street driven 1200hp rig i cant imagine his block being filled. Is there something im not seeing :s:

reading an article****

i have heard of some 650-850 cummins daily driving, some are single massive turbos but most have twins, and they just run a daily driving tune,

imo a 500 hp 7.3 would be awsome for daily driving, really thats all you need, or get ya a daily driver mostly stock and make one a high hp 7.3 for racing or pulling. :rocking:

a very high hp truck makes lots of power, but will not be as realiable driving everyday as compared to a stock truck.

a 12ver with 1200 hp would be a smokey sob till the turbos lit.:scare2:

its all what you want to do with your truck. how you build em, gotta pick and choose the things you want it to do, and do well.

oh I know the reliability part I was just mainly wondering if a 7.3l is capable and to even DD it was an option. I guess now my other question is how come the 6.0 guys can. I mean there runnin HPOP's as well and as previously stated some even on stock HPOP on fuel only?!?! :argh:

im out...:rocking: something i will put in your head though. most of the time big HP numbers come in the higher RPMS. ive never known a 7.3 to be an RPM king that could just be a bunch of BS (who am i to say) but if it wont rev you wont see those big numbers. i think 6.0's rev out much higher...i think but im a cummins guy lol

I think I might be one too pretty soon lol :tu: probably on now the 7.3 guys are thinkin :bat: but thanks for the info man

no problem
