How come no one has tried square tubed headers for a type 4?
I am thinking like the Nascar headers? I am opening up a topic to discuss the benefits of round tubing versus square tubing for headers. Also, is there an optimum size for tubing for a 2.0 liter headers??? What happens if you were to build a header with say 2.5 inch ID for a 2.0 liter??? Does is flow better? Does is effect the scavanging?? Is bigger better??? Rich |

Why don't you build a set and send them to Jake. He could put them on one of his Dyno motors. The proof is in the testing. One of the biggest problems as I see it is forming square tubing. All the bends would have to be sand packed, heated and formed an you probably still get some colapse. Or you could cut all the pieces out of flat sheet and TIG them together. Them it would diffecult to size the tube to get the same flow as round tube with the same weight or wall thickness. Square tube tends to be thicker = heavier.
