I can't speak for others, but what I offer in the race tunes is true speed density. It can be done with other stages and whatnot if the need arises.

sorry to bring up an old thread, the sdi manifold in this case was modified so it could fit standard alh pipework, could the fact the manifold was designed to be fed from the right to induce swirl be why this example has low readings

I think Ryan P suggested that earlier (maybe in another thread). Inside of the center of the manifold it's pretty symmetric. I'm not sure if it makes a significnat difference which side the air comes in - it's a cylinder with tangential radial ports evenly spaced along the length.
Someone had an excellent picture of the inside of this manifold, but I can't seem to find it now...

i was under the influence it was a corkscrew effect to get the air turned in to the runners, because if you fut an inlet with a fan blade in to help the air turn would it not benefit the inlet air speed greatly
i ask because i'm after an inlet manifold for 300hp mark

you can also look at the golf mk4 sdi inlet mainfold it's a 2 piece thing.

I have a SDI intake like the one used, it appears to be symetrical to me. I can't see a reason why changing the inlet from one side to another would have a significant effect.

If you want to test this one, I'm down for 5 weeks until the Houston Mile. We whipped this one up in a few hours for the late intake closing event. I feel that a bigger plenum, with more taper in the runners will help.
The next picture is what the new runners will look like.

Here's the picture I was thinking of (shamelessly stolen from fenwick458's for sale thread).
As far as runner tuning and resonances, etc there is not really anything that will practically fit on a frist order resonance length. At 5000 RPM you need an 18+" runner at atmospheric pressure/temp - increase pressure and temp (density) and the runner length gets longer yet. This is assuming 85 crank degrees for one pressure wave period. 15" @ 6000 RPM, 23" @ 4000 RPM.
My main goal was to test two very different manifolds and see if there was a significant difference - the testing variables clouded the results, but there was not a significant difference between the two in my opinion.
The sharp corner of the ALH/PD130/150 manifolds at the entrance of the head vs the more straight on approach of the SDI or the one LandSpeedTDI shows above were where I assumed any gains would be had.

I am told that taper on the runner will widen the band that the where the first order resonance will most benefit the port. My manifold calculations are similar to yours, but my manifold guys always come up with shorter runners. I feel anything is better than the stock ALH manifold.
here is what a 7500 rpm super charged 632 looks

Evidently not; it would appear from the data in the first few posts that the stock ALH manifold is better than the SDI.

What happened to this question? I'm curious too about Euro R32 DSG snorkle!

I've got a 3" TIP, but don't have an R32 DSG snorkle or PD150 intake otherwise I would have tested them.
I have not seen any dyno data from JarHead on this. Maybe it's in another thread?

What an awesome rubber duck! Anyone see the similarities between the taper on the 632 mani and the ducks beak?
Good one Poopie!
