Thread: 2004 L26 Grand Prix GT - Wild Cylinder Skewing from Factory (Discussion)

well, really the rear manifold flows better than the front, so isnt that skew backwards from what it should be?

Bio - you are right, This is a fact that the rear manifold flows better than the front.

All maps i have seen list the cylinders in the same order (3,2,1,6,5,4) I'd have a hard time believing this would be incorrect. - Tho I spose it is possible






I'm no wind tunnel or flow tester so i'm not sure which ports would see more air.

If anyone wants to take a crack at it, I have listed the image above with the cylinder ports numbered.
