Smoked

[Shaf]

For 40 minutes in the afternoon 3 times a week I wheel my 2008 GS500F out of the garage and run the s_ _ _ out of it.
I pride myself on only jumping on things it will out run, last Friday afternoon to my surprise a four door Ford fusion sport absolutely  smoked me.
I was able to read the license plate until 80mph.
Note: no wheelies, not over revved and no missed gears.
That V6 could fly.
I will be looking for lower gears and more high end hp.

just get a busa

If you want to race, go to the track and stay the f%$k off the road.

It's called thinning of the heard, natural selection, but unfortunately it sometimes involves innocents.

This has to be a troll.  "I pride myself on only jumping on things it will outrun"?  So you're the dbag motorcycle rider doing flybys on 2003 honda accords and acting like you just did a lap on Laguna Seca?

This is why we get ticket for running 5 over the speed limit and pulled over for nothing.

Hey Shaf, it's awesome innit. When you pull up next to that riced out civic and blow the doors of him. Fuk yeah! I do it all the time. Made it even better by putting on a 12 tooth front sprocket and a 52 rear sprocket. The acceleration is now out of this frigging world. You should try it man. Won't get smoked by any more Ford Fusions I can guarantee it. 

See you out there, brother from a different mother.

If you were smoked by a ford fusion, I'm going to go with 'poor use of the throttle and clutch.' Clutch control is absolutely critical for a good launch - my best ever, I managed to enter Turn 1 in front of most of the 450 superbike grid - filled with bikes that make 90HP or so.

Generally, cars will tend to smoke the GS500 above 80MPH. We win at low speed due to our incredible power to weight ratio... But as the speed climbs, air resistance becomes as much of a limiting factor to acceleration as inertia is... And while we do have an advantage here, it's not nearly as great as our power to weight advantage over cars... So, that 200HP engine starts being able to push a car through the air a lot better than our little 40HP engine can push a bike.

Wow... Found this from another forum... Dude managed to caluclate the CDA of a bike based just on the horsepower and top speed. Brilliant math; almost brought a tear to my eye...

The problem is that the drag coefficient of a motorcycle is model-dependent, rider-dependent, and riding-position-dependent.

It will not be a large source of error, to assume that all the power going to the rear wheel is going into overcoming aero drag at top speed.

Current litre bikes (GSXR1000, ZX10R, etc) all have a top speed of 300 km/h and all put approx 110 kW to the rear wheel. They're governed, but the drag-limited speed is scarcely different from this. From this, it is possible to calculate the product Cd * A.

300 km/h = 83.333 m/s
110,000 W / 83.333 m/s = 1320 N (This is the drag force)
Drag force = 0.5 * density * V^2 * Cd * A
Density at standard conditions = 1.2 kg/m3
1320 = 0.5 * 1.2 * (83.333^2) * Cd * A
From this, Cd * A = 0.316 (units are square metres)

This is a quite plausible number. The average width of rider+bike is about 0.6 metres not counting the skinny part (tires) at the bottom and the height (rider tucked in lying flat on the tank) is about 1.2 metres above the skinny part (the portion of the tires projecting below the bottom of the fairing), this suggests a frontal area somewhere near 0.72 m2 and a drag coefficient somewhere near 0.44 - plausible.

These engines all have ram-air nowadays. This will increase the engine's power output a little under these conditions ... but we've not accounted for the friction from the tires. For a back-of-napkin ballpark calculation, it's about right.

A typical car will have A (frontal area) approx 2 square metres, and a decent one will have Cd = 0.3, for a Cd * A = 0.6. This agrees with the general sentiment above - that no car with a comparable horsepower rating has a comparable top speed.
