    Default GL Engine 1800cc eqals what horsepower?

    What formula works to figure out what a 1800cc engine is how many horse power?
    thanks

    Don't know about a formula. I did put mine on a dyno earlier this year. It was 75 degrees, pressure at pretty much sea level - 0% correction all around. Final numbers is 103hp at 5400 RPMs and 118 lbs torque at 3400 RPMs. The power curve is fantastic. Very smooth. I'm happy.

    To clarify my numbers are at the rear wheel. I understand the 118hp number is at the crank.

    Don't matter which number you really use, they both are from the same machine and give you the same huge grin when twisting that right wrist...

    Engine Displacement

    • Engine displacement refers to the total volume that the pistons of an engine occupy after firing. Typically, the higher an engine's displacement, the more power it is able to generate. The Gold Wing 1800's engine has a displacement of 1,832 cc, which is equivalent to approximately 112 cubic inches.

    Horsepower

    • The Gold Wing 1800 is able to obtain an optimal power output of 118 horsepower when its engine is running at 5,500 rotations per minute (RPMs).

    Torque

    • Torque is the amount of twisting force -- or rotational effort -- that the firing pistons of the engine are able to exert on the crankshaft. The Gold Wing 1800 is able to generate an optimal amount of torque -- of 123 foot-pounds -- at 4,500 RPM.

    Most get about 95-105 hp at 5500 rpm and 105-110 ft lbs at 4250 rpm at the rear wheels. Depends on the dyno and conditions at time of dyno run. Torque is over 90 ft lbs from 1500-5500 rpms. That's why its such a great touring motor.

    Cubic displacement is not really an accurate indicator of how much power an engine is capable of delivering. A perfect example of this is the 750cc Magna that was discontinued after 2003. The bike is light, which is a factor; however, the Magna 750 has the most powerful 750cc engine I have ever seen in a cruiser. The bike itself is somewhere in the size and weight range close to a Shadow 750, etc., but the V-twin Shadow cannot compete with a 750 Magna with 4 cylinders and 4 carburetors. In terms of power and speed, there is no comparison. As a matter of fact, the VTX 1300 I had was not even in competition with the 750 Magna one of my son's buddies rides. It is one little hoss of a bike with close to sport bike performance.

    The HP and Torque figures stated below (at the rear wheel) are correct, and the combination of big torque just off idle and down low in the rev range, combined with the cremey smoothness of the flat-6 configuration make the GL1800 the greatest touring motor!

    Wow. 12 "flat" is the quickest time I've seen for a GL1800. Is a "dyno drag a simulated run? What year is the bike?

    The GL1800 HP = fastest enough to get a ticket. (ouch)

    it gets strapped down then you run with a light tree. I used to drag this 76 750k built up to a 836 with lots of extras at Milan, Mich. I don't think it ever got 12 flat.

    I've seen 12.70's, which is plenty quick for a fat lady. So, the fat lady sings! Sorta.

    Didn't the early 1800s make more power before the ECU swap out ?

    Did they get a reading of the AFR in the pipes ?

    Nope. This was just a pure power baseline run. No AFR done since there was to be no tuning what so ever. Was just worried about pure numbers. Plus it was free so I wasn't going to ask for anything extra then what they were offering.

    My Honda has slightly less than 1800 c.c.'s ... but 140 horse power ... and only four cylinders ...

    ... oh ... you meant my motorcycle ... I was talking about my Honda CIVIC ...

    BTW, there is no formula to go directly from displacement to horsepower. Too many variables. The GL1800, 111 cubic inches, makes about one horsepower per cubic inch, which is a really mild engine by today's standards. Some of the streetable liter-class bikes, 1,000 cc, 61 cubic inches, make almost three horsepower per cubic inch at the rear wheels! Of course, they are spinning a lot faster than the GL1800.
