Re: Merge collectors
What you'll see on the dyno data, if the headers are over scavenging, is the torque and hp numbers drop while the V/E numbers go up. inconsistent EGT's and BSFC numbers jumping. SS engines are to many different breeds to say if a merge is better, certainly not without the proper cam timing. The PS guys get away with them because their exhaust valves are so small and their ports are fast and efficient.
