I just finished this set 2 days ago so we have not tested them yet. We will take pics and video during the changing from the set we run now,:toothy10: and the set we just built. It still will not be enough for everyone. See you @ the track Don8)
I gave well thought out and educated feedback based on my past experience and this is your response??? Maybe you just wanted a pat on the back???
For a well performing header it needs to take a few things into consideration. It needs primary pipes small enough to keep the power of both the compression and scavenging wave in the pipe. They must be large enough for the optimal flow of exhuast gas past the exhaust valve and down the pipe. They need to be the proper length to keep the scavenging wave arriving at the right time to reflect back to the exhaust valve. The collector needs to be the proper diameter (and length) to provide a correct duration and intensity of the aforementioned scavenging wave. The primary and collector (combined) must produce the scavenging wave that arrives at the exhaust valve during the valve overlap period over the operating RPM range for each engine(ie the slant).
But I am sure you took all of this into consideration in the 3 days when you welded 3 -1 1/2" pipes into one 3" pipe....right?
Let us know when you get some time slips on your new PowerPipe design. You should run the same car with a stock manifold, any design you have and a set of cliffords just to see what happens.
