howzabout a helicopter turbine engine?

The 10" exhaust pipe might be a problem though, passenger seat would have to go...

I haven't had a passenger seat in 3 years, so that's no biggie. Hm, I don't imagine defrosting the windshield would be much of an issue either! :lol:

IF my calculations are right his PWR Pwr to wgt ratio is 1000 and the Ferrari is only at 266.67.

Ferrrari is 1.6 Tonne, cart is 0.1 tonne.

Formula: Hp / Tonne

300 ft/lbs of torque at 0 RPM :twisted:

lmao... turbjet diesel engine... I'm lovin' it!!!

that would be one hell of a sleeper... just have it directly bolted to the wheels... 50:1 gear ratio... the torque would be insane.

300 ftlbs of torque at 0 rpms....uhhhh im pretty sure that isnt possible.. but whatever

Absolutely possible. Electric motors, gas turbines and steam engines are the only ways to make torque at shaft stall. Dang infernal combustion engines gotta be rotating...

SMOKEYDUB · « **Reply #21 on:** September 23, 2006, 09:08:34 pm »

but all of those motors or engines have something turning some rpm to make power... no ?

what would have to be done about fuel tank and capacity? how much "running" time would be get out of one of these turbines?

Torque is not power, torque is torque, the amount of twisting force imparted on a shaft. The shaft may be stationary or moving. Twist a bolt with a beam or dial type torque wrench, note that the bolt can be stopped but torque still reads on the scale.

Power is torque over time. To make power there must be both rotation and torque.

In a turboshaft engine the gas producer always runs at its governed speed but the power turbine stator vanes can be turned to reduce the torque on the output shaft turbine and it can be stopped. If the shaft is held by a brake, the stator vanes can be advanced and the engine will produce torque even though the shaft remains stationary. An electric motor can produce torque even though its shaft is held stationary, likewise for the steam engine.

you make a good point. One thing i noticed today to was when using a cordless 14.4 volt drill, i tried to hold the end with my hand and apply power...Damn those things can make a lot of torque. SO then i thought, now i just gotta find a motor big enough to move my car, then im set!! even diesel wouldn't have anything on this bad boi!!

lol braindead for a while (g/f on the brain) torque : twisting force around a fixed point. DAMN BROADS!
