2 engines, woudl that be more or less horsepower?

Question

i am still learning about all this engine horse power stuff for cars and i was wondeirng if you took two 140 horse power 4 cylender engines, conected them with a drive shaft and both worked off the same gas pedal, would there be more or less horse power? would it be 180 hp? or would it still be 140 but a heck lot more torqu?

Answer 1

This is not an efficient solution. Even if you get 100% of the horsepower and torque of both, you have 100% of the WEIGHT of both, along with the trouble of sychronizing throttle response and all that goes along with that.

A MUCH more efficient solution is to build an engine with double the displacement or double the cylinders in a single block; or increase combustion efficiency with forced induction (supercharger/turbocharger), or Nitrous Oxide.

Plus, if you use a single larger engine, fewer people will laugh at your car, and you might even be able to sell it!

Answer 2

Sounds like a MASH episode where two people got under a blanket and tried to make "196 degrees."

You would get the benefit of both engines horsepower, up to about 75% of their efficiency, so I would guess around 210hp, but your torque wouldn't change that much. If you were getting, say 100 lbs. with one engine, two engines might get you 120 lbs., but don't count on a lot more.

Honestly, you'd be better off going with a small block Chevy engine rather than horsing around with two 4-bangers. Either way, good luck with your Frankenstein. :)

Answer 3

Horsepower at rpm (xxx@xxxxrpm) ability the utmost generated ability of the engine at that rpm(revolutions in line with minute) Horsepower is called a stupid way of measuring ability imo. If both engines from chevy or pontiac replaced into to furnish ability and be both effectual on an same rpm because the honda than i'm particular their numbers will be a tad bit closer. i imagine the different 2 designed their engines for low end grunt and in turn sacrificed a protracted powerband to furnish ability at more effective rpms. there is commerce offs for each little thing so i does no longer bounce to the end that a million is larger then the different. do not base you assumptions on top numbers. for sure maximum generated ability revolves round too many variables. seem up volumetric performance and study up on your chemistry.

Answer 4

Power is Torque X rotational speed. Yes, coupling two engines together crank to crank is done on pulling tractors, old dragsters, etc. You would get twice the torque at the same rpm, assuming they were synchronized correctly. In a standard car, all it would do is waste gas, unless you modified the gearing. Except that it would really snap off the starting line. Top speed would be unaffected unless you geared it up.

Answer 5

If there is more torque at the same RPM, the HP rating will go up. You cant have HP without torque, because HP is calculated USING torque.

HP = Torque X RPM / 5252
