Left bend_VS_right bend pipe

[Kennedy_Power]

This question always seem to come up. The pipe has a low pressure and a high pressure cycle. When I say low pressure, I mean less then ambient pressure, and high pressure being higher then ambient pressure. Once the exhaust flow comes out the exhaust port into the header pipe( being straight and more then likely a slight tapper) The exhaust flow is not disrupted with a straight header pipe, once the exhaust flows into the second section of the pipe, the diffuser, a device for reducing the velocity and increasing the static pressure. Then the pipe enters the baffle and changes pressure and velocity and pushes the intake charge back in the cylinder just before the piston closes off the ex port.
What I am trying to say the pipe is under pressure and does not care if it a left or right bend pipe.

good topic/myth to give info on. i agree with this as there is no questioning it. esecially the way you explained it. thanks again.....rep given.

so everyone is all uppty on right bends for no reason?

 

[ROCKSTAR]

exactly. that is the point. they look better!!!! but in terms of better performance, its all about the pipe itself.....what kind of power its built to make. (i'm sorry, im half asleep, if this doesnt make sense thats why, i may come edit this in the morning)

i like the right bend design better for the fact that keeps alot more heat off of the head.IMO

thats a good thought...never thought if it like that......

it also keeps the heat away from your gas tank

Thats the reason that my engine builder wanted me to run a right bend pipe. To try to keep the heat away from the top end

ill shed more light on this. banshees from the factory have a right and left bend pipe....does 1 cylinder make more power or perform better? NO! on drag bikes, you can have out of frames on the left or the right or both.....does it matter? well, you kow where im going. about the only gain is that the heat of the pipe is not near the gas tank or top end of the engine...so you have a better chance for more air to cool it.

my f7 seats about a 1/2 inch away from my head, but i dont see how its keeping heat off?

it is not directly in front of it blocking all the cool air that is passing over the head.

this all sounds like alot of "what if's" ,"maybes", and "just in cases"..

 

[darealblaster]

But i was still wondering, it seems that the Right bend pipes have less bends, would this mean the gases would escape faster? Because if you see a left bend pipe it has more bends.

Just a thought, i might be wrong.

thats the reasoning behind a righty...the faster you can get the fumes outta the engine the faster you can get new gas/oil in the engine...so ya your right

such is not the case.. if the pipe returns to quickly it's not good.. the tuned length of the pipe must work with the port duration.. a pipe that returns faster or slower than what your shooting for is an inefficent design..

just thinkin . . .

about what? how i told ya the truth?
