STR Audi 20V exhaust manifold

[Bram]

It's in! I had to grind away some iron on the WG section, to get the WG fitted properly. The rest of the holes, threads, etc. is just fine. Now it will be a, hopefully long test to see how it holds up.

Looking good, will you be reporting back to the manufacturer about the grinding so they can change it in the future?

Looks like an affordable option.

What was the total cost including shipping and taxes

Concerning the collector..... 034 Motorsport had exactly the same design of manifold and that one flows over 500 HP. Too bad that the 034 one had some issues with the material they used.

So in a sense I will be the guinea pig yes

Let's hope for the best. I will start with a RS2 turbo setup first to test the manifold

The one thing that I don't like about the way 034 (and others) flow tests their manifolds is they seem to do it one runner at a time, i.e. each runner flows without any interferences from flow that is still travelling from the other cylinders. Without the real world interferences, e.g. the flow from 1,2, and 3 knocking heads with the flow from 4 and 5, the "results" are, at best, optimistic; at worst, misleading. This is true of the Wagner exhaust manifold testing as well (IMHO). Having said that, I really like the Wagner design and would like to see one in real life as soon as they are available.

In the meantime, I wonder how manifolds can be better tested to reflect the real life interferences. Mounting them on an engine and rotating the engine with an external power source, e.g. electric motor with an overdrive gear box?? Is there a mechanical engineer/fluid dynamasist (sp) in the house?

230 Euro incl. everything

Yes I think I will do that.

Don't go there I 100% agree.

We've been through this in other threads here and it's mentioned time again on motorgeeks. I've heard that we the U.K based forum are called "haters" because we dont agree with the flow figures

hello

any updates on this manifold???? looks good

[Billman]

Any Updates on the manifold or differenses to stock S2 or RS2?

There was also a cast manifold that looked like the cheap SS tube headers. Anyone has a link of these? I think Aronmatic has bought one of these.

Still going strong on the RS2 turbo. Nothing more to say about it actually.

I will try to get my GT3071R connected to it beginning of 2008 and see how much HP it will flow. I hope it fits! I have no time this month to work on the car

[Billman]

Can you maybe give us some filing products of it. A guy in the German forum has access to a Spectrometer so we can see of what is it made of (percentage of Nickel etc).

Regards

[Bram]

Yes sure, but how much material would you need from that STR thing? I do not want to 'damage' it too much

[Billman]

Actually he need a small piece. He said the machine someway directs a beam at the material and measures content. A small cube like a dice will absolutely do the Job.

Does anyone used this mani that was sold in Ebay and now sold by Hamon-Motors?

How bad are these cracks ?
