3 Intake Manifolds 2 Prices You decide
Intake manifold without independent throttles $619
Intake manifold with AE series throttle support and you buy your own throttles. $619
Intake manifold with Boundary Engineering Oval Throttles $759
All Carbon fiber plenums good to 400*F and 3 Bar
1 can be upgraded to 3 with the purchase of another flange with throttles.
We will only be making 2 molds for these. One for the 94-97 and one for the 99-up. Options 1 and 3 use the same plenum. Option 2 uses a different plenum.
Vote now, and tell me what you want. In 5 weeks they'll be here for the 94-97 and 99-up.

All the plenums have built into them provisions for a single throttle body system. If you dont use the provision (your using multiple throttles) you just get a pipe adapter where you can bolt up your pipe coupling. If you are using the single throttle option it will work with the stock throttle, but I've also got something coming out soon that will blow your mind with throttle bodies that supports airflow to 600 hp easy. Its not just bigger, its better.

no 1.6l?
No 1.6l option? Oh well, I guess I'll just go with a custom one.

Yea, looks like a good idea. I know you guys already have a couple of intake manifolds out, and I don't have the 1.6L head to pull off yet another bolt and port pattern. The setup for just one of the intake manifold flanges past the amount of hours it costs me is around 3k for the CNC coding and tooling. The molds are 5k a piece, its alot of money to go into a market that has alot of competition.
If I get 10 commited 1.6L guys I might entertain it. Jeeze, I didn't know there were that many hanging around.

Wow, you got it before I did SV eBay Motors: Mazda MX-5 Miata 1.6l intake manifold B6 1992 up MX5 (item 350154912285 end time Feb-16-09 21:29:54 PST)
Its going in there anyways!
The manifolds are designed for the guys making somewhere south of 400 whp and on a not massively modded head. If you have alot of mods to your head, and your flowing incredible amounts of air at high rpm then you can benifit from larger runners.
Generally the torque shift will be up by 500 rpms, and extend and enhance your power band to 8000 rpm. As soon as the turbo spools you'll see a power increase over stock.

I might would be interested in the first one. I'd like to see the finished product tested first though before I jumped. IE-dyno results of before/after showing torque enhanced in the upper RPMs. Not that I could afford one till this summer anyway. Hopefully by then it will be tested and we'll know how well it works.
I do have extensive headwork though, so how would it work on these? What kind of runner length, diameter, and plenum volume does the new IM have?

Your asking for the secret sauce Pat.
The head work is only going to really effect you if your pushing the limits I was talking about. The runners flow far far more then head at even pressure drop. Once you get to about 280-300 CFM of head flow the intake manifold becomes a limit again. With an optimized manifold for 500 plus horsepower you can probably net another 3-5 percent over the current design.
With this design you should easily get 15 percent at 8000 RPM, at atleast 10 percent at 7000, at peak torque 7-8 percent at eqaul boost.
This isn't a commitment I just want to know what direction you guys would prefer.

Hmmm. Well, how about this: Is the plenum volume greater than 1.8L? Comparable to stock? Anything? Also, any flow numbers on a stock 99' head? I'm sure I added 50cfm or so to stock at peak lift. Dunno it that would put me to 280 or not. Guess I'll have to wait till there's some flow data or real world before/after dyno results.

A GOOD IM for a 1.6l? Ebay crap is just, well, crap.

BEGi - - Front Page News - 1.6L_IntakeManifold
Still not done, but they are at least working on it. I'm wondering why there are no velocity stacks in the Begi one.
But for the 1.8l guys:
Intake Manifolds - BEGi
Already have them for the 1.8l, and have had them for a little while.
