December 22, 2007 - A couple of other Miata headers.
The complete one is the Racing Beat unit I pulled out of the car. It has 1.675" primaries - only 0.125" smaller than I'm planning to use - but they're much shorter. There's a bit of inconsistency in their length, but I'm coming up with about 15-16". Really, this header is tuned to work best at very high rpm according to the math.
The other pipe is from a Boig Motorsports header, one that had a great reputation in the Miata world for a while. It's for a 1.6. 1.75" primaries that are about 29" long. I'm going a little bit longer - about twice as long as the ones in that Racing Beat unit! Packaging is going to be a concern.
