I could be anywhere from 10 to 16 hp. Determining factors: compression ratio, bore and stroke combination, cam profile, carburetor and exhaust system. All these thing play an important role in determining the horsepower. I've pulled nearly 30hp out of a little 212cc and seen some 420s fall on there face at 10. If you really want to mod a 420 you can easily get over 100hp. Just depends on all the above factors mentioned.
13.5
divide the cc by 15 to get the horsepower.
A Briggs and Stratton 420cc engine typically produces around 14 to 15 horsepower, depending on the specific model and its intended application. This engine is often used in lawn mowers, pressure washers, and other outdoor equipment. It's designed for reliable performance in various tasks requiring moderate power output.
14 hp in 420cc you take 420cc devide by 30 = 14hp
There isn't a formula for equating horsepower to displacement. That'll be determined by the injectors, the displacement, stroke, and compression of the pistons, and other factors.
Roughly 16.5 HP
You cannot convert cc to horsepower. cc is a measurement of the size of the engine. In other words cc is the bore x stroke x number of pistons. A 420 cc engine could have 15 h.p., 30 h.p, or any other amount.Displacement doesn't correspond to horsepower. Lot of other factors involved.
V6 engine - 210 horsepower , V8 engine - 315 horsepower
I have had mine up to 55 mph on a paved road. =)
The horsepower on the 1988 Mustang was # 90 horsepower 2.3 liter engine # 225 horsepower 5.0 liter engine
225 horsepower - UA engine code or 250 horsepower - UD engine code
A general rule is the bigger the engine, the more horsepower.
