Hey all, I did a lot of research on exhaust scavenging with my RX7, but with only two pipes its a lot easier to figure out.

So moving on to V8s, when you are calculation exhaust length for scavenging do you want to concentrate more on where the individual cylinders collect or where the header pairs collect, or can you get good results from either or? I am also trying to find some other useful info on what lengths and everything but not having a whole lot of luck, so if anyone has good info please post here.

Thanks

Look at Pipemax. Best $40.00 you'll spend.

They are PROBABLY both equally liable to be fucked up. However, a company like Kooks probably bought this software to make a good set of headers, and the guy down the street at the muffler shop, who is putting in your x-pipe, probably didn't.

Ask some RX-7 dudes about fit of headers, and use the software to figure out where you want your crossover to be.
