318 draw through build

This exhaust setup does look confusing... But the left bank and the right bank are joined and all exhaust gases exit via the 2 center left exhaust pipes through the turbo.
At first glance it does look like it would be restrictive but no more so than going through the turbo.
Bakerlite has Bohica2xo helping him and from what I've read of Bohica's posts, he is one clever guy.

Thanks Scrappy!

Here is the advertising for the martin system as I designed it in 1978:





And a pic of one of the later production kits - I found this one for sale on e-bay a couple of years ago:



Kind of fun to see them still in the market 30 years later. The system works well when you are using a carburetor.

The exhaust all goes through the hot side. What bakerlite is doing is replicating the LA system I built that never made it to production. Test vehicle was to be a 1979 Cordoba...

We used Quadrajets & Thermoquads. With the holley power valve, you can either ignore it or remove it. The secondaries should be rich, like 11.5:1 on boost. Primaries can be fairly rich too. The draw through atomizes fuel very well.
