Anyone interested in a new custom intake for the DE motor?
Glad you did the dyno comparisons the proper way (several pulls for both set ups and using the highest numbers), because the ECU does compensate for the WOT pulls you're doing on the dyno and adjusts accordingly. 
I'm a bit disappointed that I'm not seeing any nitrous numbers, though.

We hit 320 hp on nitrous but had a problem with the fuel delivery - didn't even get one full run in on spray...
I think the fuel pump needs to be upgraded and then we'll try again.

I believe that this manifold has the capability of supporting further HP gains than the stock manifold with a spacer. (If all you did was either this manifold, or just the spacer, then maybe there is no reason to do the manifold...) The car this piece was tested on was basically stock, what if it was boosted, had upgraded cams, pistons or a full header/test pipe exhaust system? This manifold flows better than the stock unit so with even more supporting mods, this unit can perform better than just a spacer further down the line of performance modifying.
Of course it would be very difficult to test - you'd have to have 2 days worth of dyno time and working on the car to test the full capability of the two setups.
(ie: start with a stock car, then add a spacer, then do this manifold. Then go back to the stock manifold and do an exhaust system, then the spacer, then this manifold. Then go back to the stock manifold and do cams and an intake, then a spacer, then this manifold... etc...)
Does that make sense? If not I can elaborate.
Here is the botched nitrous run. As you can see we barely got into it and managed to pull 320hp anyways. I think 375 is easily attainable.
This graph shows HP vs. AFR. Notice first it spikes lean really hard like a dry shot and then gets insanely rich. This is showing the 500 RPM lag between the nitrous kicking in and the fuel coming into play.

I don't know much of anything about the plenum spacer benefits as I've never looked up dyno test comparisons for any of them. I'll have to go looking.

Are you talking about this one?

It's an interesting idea, but I don't like how the MAF necks down. Is the built-in MAF in the stock location? I always thought that was pretty important.
