can this work ???

[fishi]

can this tune/porting work and is it to recommend to maximise transfer area?

or would it influence the mixture flowing/entrance when transfer are opening as the bottom transfer edge is not there ??

anybody has used it ever ??




Thankx

Can't help feeling a well shaped passage would flow better.

YES !

cheers dan.........
ooooooh thats a bit extreme.......
having said that......i,m sure the motor will still run.....ok......but i agree that it would be better to have some inner wall left,especially to supply the correct angle of entry of gases into bore...........

Where did you get the pic? What machine is it from?

A normal transfer wall has an 'arc' on the inside to help direct the flow.....so the increased area benefits of the cylinder in the pic maybe outweighed because of this.

Would be interesting to see it on a dyno back-2-back with an identical engine that has a standard spigot.
