How much horse power does the honda 350X have? Ive heard anything between 21-39, so im confused :wondering

well im sure its not 39, i think the avg that i have heard is 27 mabye 30 or a few more with a pipe

Ill say 28hp. Same as a 83/84R........................ :D

shouldnt the 2 stroke 250R have less hp but run at a higher rpm, and the 4 stroke 350X have all the low end torque???

the 2 strokes make more hp but have less torque. The 350x is all torque :cool:

28hp at the crank, 23-24hp at the rear.

if its like that with the 200x, 12 at the crank and 7 a tthe rear?! That seems a little farfeched seeing how fast 200x's are.

HP just helps you get to top end faster. It doesnt add speed.

I dyno''d my '85 350x a while back both N/A and on nitrous. Here's a link to it if you're interested and my old, worn out, tired machine made 21 RWHP/18 RWTQ.

Actually if you use the numbers I gave, that 12 would work out to be close to 10.

A 5hp briggs wont go 300mph like a 580inch blown hemi would at the bonniville salt flats.............................. :D

A drive train doesn't absorb 4-5 horse everytime, it absorbs a percentage of horse power. So basically the more power you make the more you will loose through the drive train.

It can. Speed is all about gearing.

:lol: sorry but it cant lol it runs out of power to get it there. Maybe in a vacuum. running it on a 0 friction surface. But if its in a vacuum its not gonna run too well lmao :lol:

I'd like to see a 5 horse briggs and stratton engine go 300mph....lamo :D

It can. Speed is all about gearing.

there is no mechanical way for a 5 hp engine made by brigs could ever achive a speed of 300 mph the weight to power ratio considering the gearing would be impossible to achive

unless your making a toilet paper tube car even then i dont belive it could ever happen


Hp- is the ablity of an engine to keep speed (roughly)
Torq- it the abilty of an engine to get up to speed

torq is wanted for trail machines because they can accelerate better but 2 strokes do better topend because they can hit about twice the rpm of a 4 stroke.

I think you would be closer if you switched your definition of horse power with your definition of torque. And the new 4-strokes out rev the 2-strokes.

actualy im going to keep my explinations the same the way they are because that is how it works!

sorry i dont meen to be stubborn but thats what it is defined as in all the books i have

What about the people that say I put a K&N and a pipe on a stock 350x and gained 5 mph, I made that up, but I've heard similar situations. I don't see how adding mods can get you speed, a stock 350x will rev out to the point it sounds like its going to blow up in 6th gear on a flat road.

The only modds that will get you a higher speed are bigger tires, bigger front sproket lower rear sproket, and getting it to rev higher.

Isn't useful torque the only measurement you really need in an ATC / ATV? The transmission is the method you use to put the best available torque to the axle. As long as the torque you are applying does the job you want horse power is a useless rating. To give you an example; some of the first old style steel wheeled tractors put out a nominal 5 HP (2 cyl) BUT applied 2500 ft/lb of torque to the back wheels using steam (at maximum pressure)as a driver, the lower the pressure in the drive vessel the less torque the less work. The theory is the same with a highway tractor 400 brake HP 1700 ft/lb of torque driven through a multispeed transmission allows the operator to apply appropriate torque in the correct manner. (In theory, not practice ;with a big enough transmission your 5HP 19 ft/lb torque Honda engine could drive a vehicle to 200 mph or more. friction and resistance says its not possible but theory says you could do it.) A jet engine (fighter)rated at 16.000 lbs of thrust cannot drive an F-16 over a 12 inch block 4 inches in front of the wheel because the engine applies no / mimnimal systemic torque yet can use its thrust to drive a vehicle at more than the speed of sound, as long as it does not have to "work" to do the job. ever see a jet car lift the front wheels?

Sorry but I'm not getting your analogies.

By definition torque has nothing to do with speed, that's what horsepower is for. Horsepower is a measurement of work performed. Basically how fast something can produce torque. It was actually a figure invented by a guy rating how fast 1 horse could produce force. Torque is simply a rating of force produced. The list should really start with torque because without this number we wouldn't be able to figure horsepower.

Torque = force produced
HP = work performed

Seems like the bottom line is that more h.p = more top speed.
Just take a look at Bonneville's CERTIFIED BIKE RECORDS http://www.scta-bni.org/Bonneville/records/BNIrecs_bikes.htm . These are records and all bikes tuned and geared for top speed. The more power output the more top speed.
Heres a link to a 15,000 horse power three wheeler that will do 526.27mph http://www.3wheelers.com/spiritusa.html .................. :beer

More hp donst always mean more speed, i saw a Mudbogger Bronco w. 500horses, cant say that it will go faster than a Dodge Charger with 5.7L Hemi that has only 364hp aprox. Thats just my .02 tho --------------> :drool:

Your .02 is worthless. :crazy:

Take say a Corvette with 400 HP, enough to rev to maybe 6000 rpm in 5th gear (drag limited). Then pump the motor up to 600 HP, so that it can rev to its 7000 rpm redline in the same 5th gear (It takes more HP to overcome the aero drag at high speed). Which Corvette is faster????? Correct young grasshopper, the one with more HP. :p

Case closed.

I think darrel632 is correct with his post. (paraphrased)

"The first old style steel wheeled tractors put out a nominal 5 HP (2 cyl) BUT applied 2500 ft/lb of torque. In theory, not practice ;with a big enough transmission your 5HP engine could drive a vehicle to 200 mph or more. friction and resistance says its not possible but theory says you could do it.

////////////////////////////////////////////////////////////////////

So now what? I believe h.p will increase top speed and a 5 hp engine will go 200 mph. Hmm....I just confused myself..lol
Maybe, since a higher horsepower motorcycle will go faster than a lower horsepower one http://www.scta-bni.org/Bonneville/records/BNIrecs_bikes.htm. It boils down to.................What? A high horsepower bike can turn better gear ratios?
I see how a same geared trike will go a cirtain top mph with two different horsepower engines. Up to a point, a very low geared ride would obtain the same mph. But start lowering the gear ratios for a higher top speed and the low horsepower engine just wont pull any harder. I'm thinking the 60 hp built cr500 would go faster than a 70cc (with the same gear). Then gear each to the best top speed and theres the difference. A higher hosepower engine will go faster.................... :beer

When going top speed in nearly anything I've tired, cars, motor cycles or what ever. I'm not usually limited by gearing by I run out of power, can't over come the wind resistance.
