Re: Dimlight Racing UM1 The fabricated runners should probably (optimally) be around the same size as the intake ports to maintain good flow throughout the runner length. The short length should be good for high-rpm power.
All the manifolds I've seen (stock or racing parts) have a large log section. I wonder if that helps with distribution to the cylinders? A small manifold might feed the first cylinder more air than the last ... might be worthwhile to use EGT sensors on each exhaust port to check.
