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:
