2 camber carbon IM prototype

[tomye1978]

Hello,
will give you some informations about our new project. We will built a 2 camber IM with very high performance for 500hp and more. Not really a easy thing and a lot of work.

http://audidrivers.24max.de/forum/vi...=4327&start=10 ( pictures scroll down please )

the first prototype was built and testet against an AAN IM. We get a flow-bench next month and will optimise it.

Here is a video you can see 5th gear begining with 2000U/min
left side is AAN right side is prototype. Only the IM was changed.

Very nice idea but i cant see any pics of it in your link.

I understand its a carbon fibre dual plenum manifold? is the whole thing carbon or are the runners aluminium?

It seems to do a good job of spooling the turbo quicker, how does it do this?

[tomye1978]

here you can see.
yes the turbo become spooling arround 400U/min quicker. It is the construction of the intake tubes that helps to get more power when the turbo isn't sooling.

very cool. how many zeroes?

Loks very nice, what price range?

[tomye1978]

Oh sorry
it looks like we built for sale. This is an privat project because we didn't found a IM that is designed without compromises and increase performance of our engine.

How did you fix the carbon plenum to the back plate and also the stacks?

looks amazing

Nice manifold Only thing I would have changed being a dual plenumb design is the use of flow straighteners between the two plenumbs. From experience all the dual plenumb chamber designs without flow straighteners suffer from uneven flow distribution between the outer and inner runners due to the turbulance introduced on chamber transition.

The improved power delivery will come from the internal trumpet design as a nice radius helps stabilise airflow at lower rpm giving improved of boost performance giving the onset of power earlier in the rpm range and greater throughout. I've seen this many a time on S4 and RS4 manifold internal trumpets where careful radiusing of the original casting gives for a much improved low and mid range along with improved power throughout the rev range.

Thanks for your help. We built this first version without any aero helpers like straighteners. After we have made the flow bench we know where we have to optimise with thise things.

How is your design better than a dual plenum from Pro-Mo or Furans?
