Ladies and Gentlemen:
I want to have a discussion... Is there a market (however small) for a tubular exhaust manifold / shorty header for the /6 applications?
I know that Dutra has the "split manifold" side of things covered well. I am wondering if there is interest in a tubular manifold that is OE shaped (with some performance adjustments), to A: replace broken manifolds, B:clean up engine compartment, and C:add performance/efficiency/flow to a build that does not want long tube headers.
Here are my thoughts:
OE shape, but stepped. Each "primary" would be 1.5" off the head, and curve into main body. Cylinders 2,3,4,5 would have a taper at the end of the primary that directs the flow towards the center, instead of a straight "dump" into the log portion of the manifold. The "log" portion would step up in size after each primary joins to give additional volume. After 1,2,and 3 are joined, and 4,5,and 6 are joined, it would be a 2 into one merge, like a header.
I am open to ideas on how it could be tweaked to heat underside of intake like OE design, if that is of interest. Maybe those who would use this do not want that feature?
I tried to draw a picture, A 2 year old could have done better.:toothy10:
The collector could even be tapered at an angle instead of straight down.
In my head it is mostly OE shaped, but each primary would taper towards the center, instead of dumping directly into the log. Flow would improve with the taper, with the step in primary log size, and with "collector"configuration.
Initially it would be mild steel. Stainless, TIG later?
Your thoughts?
