Badass. Looks like getting to the top bolts on the flange will be a bit harder than a stock manifold now. Question though: Would just welding a piece of metal over the back, essentially no dome at all, just a corner, hurt anything performance wise? IE-is that hemisphere thing for looks, structural integrity, performance, or all of that? I've been contemplating intake manifold designs forever. I'm gonna end up building one similar to a ford manifold for their I4 turbo mustang engine most likely.

Dunno about the bolts...well see, but that's what universal joints are for!

Look at Begi's manifold, they use a shallow dome, I should have done that...less volume behind #4, creates an area for air to circle around and ****. A better design would be to taper down into #4, but I dunno if I would have wanted to use a straight wall. When I ran this design through floworks, the trajectory plots that don't shoot straight into #3 and #4, follow the edge around the hemisphere and circle back into those ports. With a straight wall they bounced around all over the freaking place. With a taper all paths went straight into the runners.

Yeah, I bought a snap on 12mm socket with the built in swivel just for intake manifold nuts. If I ever come up with a design for an intake manifold, you wanna model it with your fancy software skillz and see if it sucks or works well?

sure....

this was my favorite design:



Basically a 45° angle on the TB inlet tapering out to a D-shaped plenum with a taper at #4.

cool vacuum distribution block. I almost bought the crap at lowes last night to make one until I found the cost of materials would be about as much as the premade ones.

Will be interesting to see what it does for you. Get that baby mounted and on the Dyno so I can start planning my next parts to save for. Intake like that or 99' head. Hmmm....

What TB are you using with that?

Pretty sure he's gonna be using the stock one.

Looks nice brain, where is the dyno slacker?

He's a panzy, its too cold for him <limp wrist>. All the global warming in the world wouldn't make it warm enough for him to put it on in the winter.

Ahhh! I love this setup. V mount...horray!

Hood gonna close?

isn't that design gonna flow an awful lot more air into #1 than 2,3,&4? It's basically a straight shot from TB to #1.

nah, the teardrop shape is a good design, the airflow follows the edges and distributes the air fairly evenly.

i need to get my car running today so i can drop it off at BEGi next week and get one made for my car.

Cannot wait for updates, remember talking to my mother and she said it was snowing in her area.

yeah, it was yesterday. right now it's 32*F out and I'm a big ***** when it comes to working in the cold. I don't even have a garage right now to work in. I suspect it will be a few weeks before it goes on, then expect a dyno run soon after.
