The fabrication has begun...

The number one and two pipes will be routed around the sump at the back(pulley side)

I haven't got much done because it was a party last night... and now is one more

This is all you get for now

Update 2005-06-06

Continued the fabrication.. here is the number4pipe done

Another angle

The maindesign is done and the number2pipe needs to be finshed!

Another angle... the camera fouls the eye.. the welds doesn't look that bad

Your idea is right, but your collector tapers too fast. You will create reversion and excessive back pressure. Shallow up the angle where it comes together. http://home.mindspring.com/~tooltime1/Index.html I think it is listed at the bottom of the custom fabrication page. That is a header I did for another turbo car. THe weird header is for a formula car it was not a very good design but it was done in a hurry. The rams horn manifold is the one I am referring to.

I think he means this one. It's on the projects page.

Actually, this one shows the collector a little better.

Sorry, I can't figure out how to put a picture up here without having a URL for it. If you look at the website I listed look at the first header shown in the custom fabrication section of Current Projects. See how the collector tapers at a much less abrupt angle?

That would be the pics.

Using that heavy pipe would definately be the ticket for making the "perfect" collector, and it's very easy to weld too.
(Not as perfect as those Burn$ units though...)

well.. you need alot of pipe.. and using weldels makes it really heavy.. (I've tried

)

Mine was made as an experimental piece, it will get re-done in stainless. You should be running at least 16Ga tubing with some sort of Ceramic coating otherwise the heat will kill the steel tubing in short order.
Yes Weld Els are heavy but they keep heat in the pipes and keep exhaust gas velocity up. For a short manifold like the one I built they are perfect for your application you are better off with stainless.
