Tubular Header attempt for fp3065

Thanks for posting all of that, good read I enjoyed it.

Thanks for posting the info on temps too.

looked better without the coating

Agreed, however looks wasnt the reason for doing it.

We will get up some logs with the boost response and more temp info once we have a chance to.

we will also be logging pre turbo exhaust pressure.

Thanks for posting test results

A dyno is the only way I can think of heat testing the manifold. Timing belt concerns may be unwarranted because it's is constantly moving, It'll be much less susceptible to burning vs a stationary object. Still worth the dyno costs however, and maybe a comparison to a FP manifold (for example).

Regarding boost response, the 3065 is a popular turbo so we should be able to compare logs. Personally I like logging throttle vs boost at various RPMs. This gives you an idea of the response instead of trying to ascertain from a dyno graph or subjective description.

good job !!!!

Just out of curiousity-- how does a manifold affect the exhaust tone / note? I'm just interested in what factors contribute to an audible difference in the way the car sounds. Like for instance your extremely long runners vs. an EVO III manifold.

Slip joints, every good manifold had them in certain key areas. Or the weld will crack eventually there is a lot of thermal expansion and contraction at certain points. Also you gotta think how air flow under the hood will cool the manifold in some spots, but not others.
