Default Turbo manifold question

I want to do a turbo manifold for Tiburon. It's not a problem to find good welder for good price in Ukraine.

1. What should be the diameter of the pipes?
2. What material to use (stainless steel?)
3. Is length of pipes important? Should all pipes be the same lenght.

1) Diameter of pipes depends on what PSI and such your going to run.

2) Stainless Steel would be best. You want something that doesn't lose heat very fast, and Stainless Steel is good at that. If you want to go cheaper, you could also use Mild Steel for similar results.

3) Equal length creates the msot power but is more expensive to make... once again, if you want to go log style and take a small loss of power, Log style is fine.

Yup what hamhead said, stainless is the way to go. Heat is what turns the turbine wheel thus creating more power. You could also go with Mild Steel and get it ceramic coated, but if you do the same to stainless steel it's even better, obviously.

Try to stay away from the log style if you can, it's just not efficeint.

You are going to make your OWN turbo manifold?

It really would probably be cheaper to get one online man.

Depends on the PSI you are running. At light PSI, the change won't be alot. When you start boosting fairly decent, thats when you start seeing the results.

Also look at in exhaust pulses. The first tube will see 1 pulse, the second will see 2 pulses the third 3 and the fourth will see 4 pulses. There will be a heat pocket just before the turbine. As metal heats up it lets heat escape better than normal, heat is what turns the turbine wheel thus creating the power for the engine.

sounds like its a must if you want serious power...well the thing that i really hate about how it looks is how the welds in the pipe looks...if i got that ceramic coated it should make it look pretty good huh? does anybody have pictures of a equal length manifold either colored(if you can color it) or ceramic coated? The appearance isnt as important as power but looking good is nice

I mean it will look good if you wanna polish it too. Ceramic coating is a great way to do it. You do have a point though. It could make some serious power, but if it doesn't look nice, well............... just read the thread SMT-6 vs SAFC

What should be the diameter of pipes?
I'm going to build setup to run up to 200-210 hp on stock engine (with lowered compression rate).

May be it would be better to do a manifold (up to 300-350 hp) and run 200? There will be reserve for further tuning.

What length will be the best - as short as possible?

What is log style manifold?
