Inlet manifolds flow test

[terrybullwon]

I saw this on Zatzy, I hope Martinssons does not mind them posted here to...

RS2


AAN


034


3B

[Acidburn]

Some interesting information there as I remember seeing this before.

3b's good for something else again

034 one I take it is a chopped or reverse one?

[s2_bo]

So 3b does flow more then RS2, there was some debate about this a while ago.

Peter, the 034 one is reversed as the injector mounts are on the other side. Wonder how the manufacture is though? It doesn't look like a Wagner one unless its reversed.

cheers for that, I was not sure.

I'm trying to decide what to put on mine either the 3b or the porsche or even a reverse one?

I always assumed that the RS2 and ABY are identical internally (just badge differences on the outside) but has anyone ever demonstrated this?

Grant has an AAN inlet which has been port matched.
His power levels are good enough for me.

I think this test was performed by 034 Team and posted over a year ago in Motorgeek.

That is correct. Javad did al the flow tests. The 034 IM is from Wagner AFAIK.

The RS2 IM is different from the ABY and 3B as it has more capacity.

Really? Has anyone ever proven that?

If not, does anyone have an RS2 and S2 IM kicking around that they could fill with water to check the capacity?

If there IS a difference, does anyone have an RS2 IM for sale?

I'd be interested to know this as like I said above i'm trying to decide what to fit to mine as the rs2 has to be modded to fit the 3b as newsh found out.

Javad confirms that the RS2 IM has about 1 liter more volume.
However the flowbench numbers show me I will never put a RS2 IM on my car!

Does that mean you have an RS2 IM that you might not fit as it is no better than the 3B one? Wanna swap it for a VDO boost gauge? :mischeif:

I think you can still reach high HP numbers with a RS2 or 3B IM (good for at least 516 WHP), but it's just the unbalanced flow over the 5 cylinders that I would like to prevent.
What I mean with this is that actually each cylinder has got to be tuned with a different AFR, while now you tune the whole engine on average AFR over the 5 cylinders, meaning some cylinders run a little richer or leaner. I guess you will get most performance an a equally flowed IM.

Here is Pisobiker confirming that the RS2 IM has a capacity of 4.2 liters (incl. runners).

The 3B IM has a volume of 3.3 liters.

[HPmuirt]

Javad confirms that the RS2 IM has about 1 liter more volume.

That is between a 3B and RS2. He makes no mention of the ABY. I always assumed that the ABY and RS2 were the same internally, anyone care to comment?
