How much HP does increasing compression add?
The generally accepted gauge for adding compression is that one full point of compression can add between 3 to 4 percent power. So, if an engine is making 50 horsepower and we add a full point of compression (from 11 to 12:1 for example), this could potentially push the power to 51.5 horsepower.
How does compression ratio affect horsepower?
The compression ratio has a significant impact on engine power, fuel economy, emission, and other performances of internal combustion engines. Basic engine theory states that a higher compression ratio produces higher torque and horsepower.
Is high or low compression better?
In general terms, high compression (which is a relative term itself) is desirable because it enables more power production. Each cylinder-full of air/fuel mixture will have more room to expand and do work, making the engine more efficient.
What happens if engine compression is too high?
Engine damage can be caused by compression pressures that are too high and can result in difficult starting and detonation.

What size engine is a Suzuki M109R?
1,783cc
Suzuki’s biggest Boulevard draws power from a large 1,783cc liquid-cooled, 54-degree V-twin engine that produces a brawny 128 hp and 118 lb-ft of torque. The engine uses Suzuki’s Dual Throttle Valve fuel injection system to deliver smooth power even at low rpm.
Why is the M109r so hard to ride?
The M109R gets jarring when going over a bumpy roads, and what makes it worse is the “hunched forward” position means your spine soaks up the bumps. You can’t stand up on the footpegs like on almost any other motorcycle.
What RPM is the BMW M109r in Top Gear?
On the highway, the M109R is in its own element. Depending on your cruising speed, you’ll be cruising at 2,500-4,000 rpm in top gear (remembering it only has a five-speed gearbox!). The M109R is totally happy at these RPMs.
What kind of motor does a M109r have?
The big M had a 240-section rear tire when they were still an oddity; the motor revs freely, while also putting out good bottom end; and the suspension was well beyond what most cruisers can claim. The M109R is a muscle bike with a 109″ (1800cc) motor, and we’d like to assume the ‘R’ is for racy.
How fast is the Suzuki M109r?
Like the Hayabusa from the same stable, the Suzuki M109R is known as being fast in the cruiser world. A 1783cc (109 cubic inches) liquid-cooled dual overhead cam 52 degree V-twin engine (a cruiser engine but it needs valve clearance checks) Claimed 118 pound-feet of torque at the crank; measured 96-98 @ 5,100 rpm at the wheel by various magazines
