This is the plenum design I will be using for my new upcoming intake manifolds (b/d/k/f20c/f22c/h22)

I can But how in the hell did you tack that huge gap? I could never do that unless I had a big fill rod.

Re: new plenum design check it out
 
that "huge gap" is only 3/32nd" and the material is 1/8"
after 4 years of welding aluminum it is very easy

I really recommend getting a superflow in theory alot of things work but oddly enough alot of the time this doesnt happen. People have ragged on square plenum manifolds but they perform.

The 3S I tuned day before yesterday had a mild steel square plenum IM, it really amplifies the entire engine sound. Not that this is a bad thing, just an interesting note.

Each set of runners will be specific to the engine and the person who orders it (will have a info sheet that must be filled out when you order the manifold)
I will also have a shelf version that will be good to factory redlines of the engines

Hell, I'd drive up the east coast to strap Noel's car to a dyno for free... I just want to play with the pretty pretties. ;D

looks great. You can whip one up for a B16 head and give me a SPECIAL price on it. I'll run it on my car and vouch for your great manifolds ;D ;D :y :y doesn't have to be a perfect perfect model.

A teaser pics of things to come ;)
That is twin injectors and direct port no2 boss all crammed in there

Custom fuel rail will be made to match the injector angles

This is just preliminary design alot more has to be done before it is ready to be cut
Will be fully modular intake manifolds

woow, when you have to run two set of injectors, that when you know your making a little bit oh horsepower.

twin 1600 still good for 900whp range, still plenty to run high 7 low low 8

What's wrong with 116? That ---- is cheap if you buy it four 55 gallon drums at a time, it's easy to arrainge a group buy with anyone serious minded local to you.
