:shock: damn
81lbs of boost :shock:

The M1A1 tank has 1500hp and 4000 ft/lbs tq. :notworthy:

with 300hp, and 600 tq.
I know of several well tuned cars that produce higher tq then hp. One is a volvo, and it produces almost 100 more lbs of tq then hp.


Hp is derived from torque and rpms, if you have an engine with a lot of torque but can't rev very high then you'll get a very torqey motor with a low peak hp output. Another way to look at it is that you have an engine that is very efficient at a lower rpm than at high/redline rpms.

The WRC cars most likely have a very different hp and torque band than most street cars. Largely due to the restrictor and different design changes to work around that.


Yep Yep! Agreed! :)

Because they are measured at different RPM.


They aren't measured at different rpm, they just occur at different rpm.
Torque is of course the circular force the engine is producing. Max torque is when the engine is pumping air most effeciently, and hp is simply torque X rpm, so max hp is simply the point where the torque x rpm is the highest #. So you could theoretically have max t and hp at the same rpm. Never seen a engine that way tho :D

And here I eat my words.

I've seen ones on Navy ships, but not that big or that good.

"Even at it's most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour."....man i just got back from the gas station and it was $1.99 p/g...i would not want to fill that thing up...

"Some high-performance auto engines have a similar feature where an oil squirter nozzle squirts oil onto the bottom of the piston. " what engine has that?

right...

Hence the reason I asked " Are you serious "

Pretty difficult to judge sarcasm on the internet buddy... I was trying to help, thinking you may not know. Have a nice day.


Peace
