Pressurized or not, the best was to get air to flow good is nice long runners with very easy curves. I'm not saying I'm an expert, but just throwing in my two sense on how I see it working. Still nice to see someone is finally trying to make a different manifold for the lsj though
yeah, I think starve is the right word, more flow right. cause even though its under pressure, the air still needs to flow, but with the short distance, its gonna want to flow straight into 2 and 3, and will flow out to 1 and 4 when the valves on 2 and 3 are closed causeing the air to kinda bounce back and forth in the mani and causing alot of turblance,

when the manifold is under pressure air dosent flow until a valve is open then all the pressure shifts to that port and so on

The Geriatric Depression Scale (GDS) is a 30-item self-report assessment used to identify depression in the elderly. The scale was first developed in 1982 by J.A. Yesavage and others.

It's nice to see ZZP still producing/testing new parts for the LSJ crowd, but the intake side of the engine is really not the problem....
A nice exhaust ported head & cams is a far better upgrade IMO.

There is nothing wrong with my comment. GMR spent lots of time designing/testing all out performance for the Time Attack car, and didnt mess with the stock intake manifold other than adding a dual pass endplate.
Again, it's nice ZZP is still making parts for us, and testing things out.

On the Laminova site it is stated that: An estimate figure is that you’ll need approximately 2.5 mm core per horsepower
Our cores are 198m x 4, so good till ~317HP. And that is probably crank HP withour SC losses, so for high HP Harrop builds it will help to have additional cooling capacity...

OK, but what if you already have a ported head with decent cams and still getting high IAT's with a Harrop on full song?

I've been around long enough, and seen many attempts at making our intercooling/intake manifold better w/o any great gains (air to air, ported, different H.E.'s, etc.). People can continue to try, but I still feel it's a waste of time.
Even ZZP admitted it wasn't worth the money per gain after they tested it. Maybe something will be produced in the future that will work.... who knows.
On a side note, most the people that were hoping this will work are not even pushing the limits of the stock cooling/intake manifold system.... and prob never will.
