It looks damn sexy. I am curious about lower rpm power losses (sub 3000rpms) because that is where most of our cars spend their operating life.
Another thing I'm curious/worried about it is were will the PCV line go or will oil just get flung all around the manifold or will this require a catch can.

yes i i can't tell you who unfortunatly
in any case this design by cosworth looks very nice... but still if you are only going to gain 10whp more than if you add mrev2+ 5/16" spacer its not really worth it, unless you are like BamBam, with resources and a ridiculous monster Z and not much else to do at this point to make more power =] I wouldn't compare to the ssv crap, we all know it sucks...

Not sure about the resources comment, but I think the best bet is to wait until it is released and someone does some before and after dyno’s. Should be both on a NA and a FI car. Maybe even something like a stock FI system and then a heavily boosted system (like Sharif's Z) to show the benefits to a more modified car pushing 15 – 20+ PSI.
This would allow everyone to see the benefits for the various applications and make an educated choice. To me, if Sharif shows it helps solve some of the intake flow restriction problems we are having at high boost.. I would be willing to pay the price, but won't know till it is released and comparatively tested.

It still looks as if the front 2 cylinders would starve for air compared to the other cylinders since the air is still entered from the rear... I will waitt o see independant dyno's before I take the plung on another intake..

the thing I never understood with the thing with the front two cylinders being supposivly lean is when you reduce the volume area that air travels through - like the slant tapering off on the stock plenum, air pressure increases there. It'd seem to me that something like that would actually be what you want to keep the air moving quickly to those front two cylinders? I'm not convinced the stock one is a "bad" design or actually does lean out the front two cylinders
I'd think that the bigger upper plenum like the crawford etc simply gives more air available for fast throttle adjustments and increases power.

SFR was working on a manifold but I think the project died. It had longer runners than most.

The Kinetix SSV has longer runners, but we all know that got them nowhere.
Besides, turbocharged Z's aren't hurting for low end power, it's carrying it out to redline thats the hard part.

If it's feasible, i will dyno my car with it N/A before I change my setup.
