Title: Harley drag racers
Post by klx650sm2002 on 11/07/10 at 08:26:42

Harleys can give away power to a 4cyl bike because they have a traction finding power delivery (second only to a single). and look at those bellmouths. The bike on the left has a left hand bellmouth which is odd for a harley, maybe has one on both sides.

Engine
1511cc Puma/Kawasaki
1000 horsepower estimated
70mm stroke, 83 mm bore
59: 1 compression
OOOkay, 1500 Cubic Centimeters (One CC being about a sugar cube in size) producing 1 THOWZUND Horses is about .666 EEEEvil horsepower Per CC.

Folks, thats CRAZY power per displacement unit.

I Wonder how they get it to do that..

OHH, LOOK! Theres a clue..

59: 1 compression

My 1st thought was that you fotoshop'd it, but I see that his hand is resting on a flying jug.

Brings new meaning to roasting chestnuts on a open fire.

Something else I found amusing was when they state it's based on a Hayabusa engine. In that respect I suppose you could say it's based on a Model T motor in that it's 4 cylinders ;D

If they're running on gasoline, however premium or even aviation grade gasoline, I can understand 15.9:1 compression, but never 59:1...

15.9:1 is good for a diesel, or for any kind of detonation-powered combustion.

59:1 means you have 58 to 60 bar (atmospheres) pressure on TDC, I have yet to see piston rings that can take that kind of pressure before combustion. :o
