Help - AAN - ABY - ADU exhaust flange design

[aspro]

Does anyone have a good exhaust flange design in either DXF or DWG for the AAN / ABY etc. i am currently developing a cast manifold.

Yes i know the flange in the drawing is not correct.

Ohh, tell us more We like a good bit of Exhaust manifoldage on here

Hi there

decided it was time to start designing a solid reiable cast manifold for the ABY family.

I have been designing little bits n pieces for Audi's for a while now, mainly for my 16v coupe on throttle bodies.

I have recently upgraded to a URS6 an started to look into points of failure.

I currently have a cracked OEM manifold and had started looking at options other than OEM but wasn't inspired by either the quality or design of many after market stuff, esspecially anything welded togther from stainless.

So decided to get a base design layed down thats sympathetic to firing order and can be tweaked easily to provide more or less flow.

Have you had a look at this thread. Wagner has been making high quality manifolds for ages. Maybe you can pick up some knowledge there.

Yes looked at that thread - but thought it would be nice to have a british contender.

[Billman]

Yeah, what would be the price from the british contender and what material? Take a Look at the MTM or the Sport Quattro manifold design. They can flow for over 500 bhp.

Keep us posted.

Hi Billman you are right the price to cast and pattern make in this country would be v expensive.

What i am trying to acheive is a solid british design that can be produced elsewhere. in 2 sizes 1 as standard and 1 to RS2 and above spec.

also looking at pressing the main part in two halves see image - maybe inconel

Does anyone have a DWG or DXF of the flange for an ABY / AAN.

Sounds very interesting!

Could you not just copy the flange design if someone provided you with an EM?

Is that solidworks you are on there?

Cheers,

Steve.

sorry not hydro forming but pressing the two halves then seem welding

would be more than happy to measure up the original, i have done a few inlet and exhaust manifold flanges in the past and worked from the gasket. i actually put them on the scanner at work to get a 100% scale image then bring that into cad and start measuring.

I have flange designs for a few VW engines already ACE and 7A inlet and outlet if anyone wants them.

If you have the design for a 7A exhaust flange, you can use that for the ABY, it's the same.

Sorry correction 7A exhaust is the only one i don't have !!

Here is the Audi Flange for you!

Are you Designing that Manifold for a Diesel?

Good Luck...
