Bruce/Jason-
His comment was that it sounded "uneven". That doesn't really mean anything to me. He thought a crossover would make it sound more balanced. If no two cyclinders are firing at the same time, wouldn't the crossover allow the side that had just fired to "pull" the spent gasses from the next cyclinder to combust? (trying to figure out why V-8s have crossovers and APS didn't build it that way)

If you can't make it to Fresno on time, then you should party with us!
Rob said he had a couple of margaritas last night, so he's in training.....

The freezing level on the Siskyous Pass is moving up to 6,000ft, so my return trip is looking great.

 

WRT "wouldn't the crossover allow the side that had just fired to "pull"....


This would be true in an NA or SC application, not really so with TTs ,once you have placed a turbo impeller into the path of the exhaust mani , the pulse-scavenging aspect of the exhaust flow is pretty obliterated from there on back. A cross-over may help balance sound quality but I seriously doubt you'd get any scavenging improvements. Addtionally insertion of a crossover can actually distrupt (turbulate ) the laminar flow in this application , though I doubt you'd see any perfomance difference at these intermediate CFM levels (<600rwhp). Just my IMO.
