Interesting. +1 on 1.6 manifolds. Although I wouldn't be able to pony up for one now, it is something I would be interested in later on.

wrc2tuning 02-22-2009 02:04 AM

Ill take a 1.8L 99 FI manifold, and if you want a tester i'll buy a Manifold and Adaptronic Standalone If the price is right! I voted for the Intake manifold with Boundary Engineering Oval Throttles for $759

pschmidt 02-24-2009 12:27 PM

Will the manifolds have provisions for IAC, EGR and all that other good stuff? OBD-II compliance would be a huge bonus.

TravisR 02-24-2009 08:14 PM

Yea I will be building that in. I just hope they don't pop the hood at the emissions center. A big chunk of shiny carbon fiber probably isn't going to cut it for emissions. :giggle: I appreciate the offer WRC, when I get there I'll send you an email.

Father LeadFoot 02-24-2009 08:36 PM

I'm interested in one for use with a Single Throttle Body.

bryantaylor 02-24-2009 08:56 PM

i would rater raise the boost 1 psi than spend $700 on an intake.

Well then this manifold definitely is not for you. This manifold is for people who rather increase the flow, lower boost, lower intake temps AND increase HP. And of course those of us who are beyond the flow capabilities of the stock manifolds.

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.

I've seen the 3d image on your website, and I think the image in my head is gonna be different than the final product. I pictured an enclosed carbon manifold leading to a single opening for a throttle body mount. I think i'm kind of stupid. I imagined bolting my throttle body to carbon fiber. :bang:

Travis, maybe you can clarify some things for me or you can tell me to just be patient and wait for pictures.

Will the BE manifold with oval throttles be enclosed and lead to a single throttle or will it be enclosed with multiple throttles?

If it's ITB's, what brand would you be using?

I'm really looking forward to seeing more pictures to get a better idea of what to expect.

This was covered earlier in the thread. The BE throttle butterflies are built into the base of each runner. If you look at the base you'll see the throttle plate shaft sticking out. At least that's what I understood?:eek5:

Travis: Still on track for the 5 week mark for these? And any update on the Timing Kits?

We are on track for 5 weeks so far. Timing kits are being tested. I'm willing to sell engineering samples at 300 for the whole kit. I have one set of engineering samples left.

Yeah, it was covered. I went back and read the thread. disregard my noobness :bang:

So this week is week 5, just curious if your getting your prototype finished up or its going to be longer. I'm interested to see a real life pic!

Father LeadFoot 03-16-2009 01:33 AM

What Throttle Body bolt pattern are you making for this? Will it only fit a stock throttle body or are you making it for something larger, like a 70mm mustang TB?

Fact checker :giggle:

I'm expecting flashy carbon by the end of next week.

I have something I'm making, but what I'll probably do is just tube the manifold out to a 2.5in and then let people silicon clamp on different adapters that I CNC machine. That gives a little flexibility in the throttle location, and you don't have to make a different manifold for every variant. So one will fit the stock throttle body, one will fit a mustang throttle, and then for the IRTB guys you just attach your turbohose instead of a throttle body adapter.

Just to clarify here when I mean silicoln clamp on I mean your going to have a material interface between the manifold and the adapter. Then a silicoln clamp air seals the joint and keeps everything rigid. Its not like a limp noodle throttle mount.

wrc2tuning 03-16-2009 02:47 PM

Great :bigtu: how is the CNC work going on the actual IRTB's?:eek4dance

Fra66L 03-16-2009 04:22 PM

Voted Option #3 but will it work for RHD (clearance for master cylinders etc)?

That part is easy, its built right into the flange. You'll love how its setup once you see it. The butterfly is as close to the head as possible and it actually hangs into the port when open. I suspect the non-ITB version will be available first though, it is the easiest.

I don't know, you'll have to give it a spin to see. I would not think you would run into problems though the plenum is not huge and its not that close to the firewall. If the stock manifold fits over there this will too.

So Travis,

Do you have an estimated completion time for the ITB kits to be available?

TravisR 03-19-2009 09:39 PM

I'll really know at the end of this next upcomming week where we stand.
