700 hp tow rig? lol

i have a few hypothetical questions here for a hot rod tow rig.

so what are the limits for reliable power and boost pressure?

what keeps me from making 75-100 psi of boost reliably and regularly.

also, what says i cant have a 700 hp motor in a tow rig, and use it too. aside from the rest of the drivetrain reliability concerns.

please no responses of why do i need that much in a tow rig. this is just a because i can type of question.



lets assume that there are no cooling troubles with a big enough radiator and lets say i have studs and an oringed head, stock pistons, and maybe even a + 0.020" head gasket.

what is the max boost and timing i could run reliably like this?

what parts could fail in a situation like this?
what are the limits?
 
being in the 700hp range, i would hate to tow anything more than say 3K lbs

i dont think it would get very hot, engine temp wise

exh temp will be a different story, lots of factors there
 
Are we imagining that you have a large enough radiator to use that power for long periods or is this real life?
You can use the right turbos and fuel system to keep EGTs in check but around 450-500hp people are finding that the cooling system can not dispose of the all of the energy that it is absorbing.

700hp isn't too much for the stock long-block if the added components are chosen wisely and tuned well. There's a lot more to keeping an engine together than just max boost though.

yes we are imagining a perfect radiator.

in a situation like this with good tuning, with a stock longblock what is the week link?
 
Most people use the radiator from a Mack truck under bed and put hydraulic driven fans to help cool it.
 
I would like to see how long the driveline would hold up towing 12K using the 700HP frequently!

Better double check your ricer math, and be sure you are counting all the stickers.LOL

ricer stickers are multipurpose: not only do they add power, they make the car handle better, and can be used to cover up paint bubbles and rust spots...
 
lol. this is pretty much where i figured this thread would end up when i originally posted.

everyone pretty much missed the point. :bang ha ha


i am just asking the limits of the longblock under sustained high output use.


lets try this again. this time pretend it is in a kenworth and forget about cooling of any kind. it is all perfect. or a boat with unlimited cooling. :Cheer: lol
 
Since I do not see a truck mentioned from you or in your sig, Lmm duramax, built motor/tranny, efi live dsp5, twin turbos and two stage nitrous. 700 hp and can tow all day long. Just flip the switch from tow to race. Still not the smartest thing to do.

i got an idea y dont u build a truck with 700 hp and tow with it and you tell us what breaks first haha lol.LOL:badidea:
 
lol wow. my truck is a 97 f350 that i am putting a 12v in.

but, my question is simply a hypothetical one and has nothing to do with my truck. :bang :bang


oh well. i give up. ha ha. time to go build something.
