Ford also made a manifold that I used on the ZETEC that had that full reversal of flow. The thing flowed great from 5000 R.P.M. but was a pig below that, I believe that was inhearent in the runner the design though. You could stick your hand in the mouth of those runners. (Yea I looked pretty funny with my arm in there just to try it.)That may be the best way to ensure even distribution though. The down side is T/B placement. I've been running my CosmosFlowWorks solver pretty heavy lately hunting for my optimal plenum design, I need more ram...

I was thinking about inverting the Cosworth Duratec design. Instead of Scott's 45-degree runners, make them straight, and maybe a little shorter. The throttle body would be above them in the stock location, and the plenum would wrap around downward. The exact implementation would depend on preserving access to oil filter, clutch slave, etc.

One European Audi tuner made a 1.8t manifold that was basically a straightened out turbine scroll, with the t/b feeding a chamber that tapered along its length, connected to the main plenum by a long slot. If done right, the flow through the slot would be uniformly distributed, and the charge would trade its velocity in the intercooler piping for pressure in the plenum very efficiently. That part of it might be something that would display very effectively using FlowWorks.

Summarizing my thinking of the afternoon, it makes sense to have low velocity in the plenum, and you want to do everything you can to keep the cylinders from screwing with each other.

here you go:

Attachment 209877




looks like the RSX-S has a similar design to what you're really talking about:

Attachment 209878

Cosworth and Honda on the same page. I'm in.

Yes, but they're on the same page when it comes to n/a designs. I haven't seen any marques using that design on a FI system yet.

K series love boost.

any news on the Intake manifold?

+1

They are going to test the stock replacement, on my car, probably next week. I was hooping to get it done this week, but Tim had other stuff to do first.
Stephanie

Send it to me, I'll weld it. :p

updates?

Pics of mine? :)

My Xede just got back today. So in it goes and then to the dyno. Then the intake manifold. Not quite on schedule, but it will make it.
Stephanie

updates?

+1 updates

My car goes to the dyno in a week for baseline tuning. That was the earliest we could schedule it. The Xede and injectors are back on/in it. When it comes back, the new intake manifold, with the longer/round runners, goes on. It goes for tuning again probably the following week.

I am going to try and make them put an EGR on it and more vacuum ports. We'll see how far I get with that one though. Corky does not want to make them EGR compatible.
Stephanie

the vac lines would be nice..

Edit: Any pictures?

Steph, I wouldn't bother with EGR. The only thing stopping me from ditching my EGR is the blockoff plate on the IM; if the flange didn't exist it wouldn't bother me in the slightest. I sincerely doubt the folks that are changing intake manifolds in search of power above 5000rpm care much about smog or legality.

For what it's worth, I'm going for 400+ and care about both.

I'd think from a sales standpoint that having those items would make it easier to sell. Vacuum ports is a no-brainer and having the egr makes those looking for smog legal happy, while those who are not, can just block it off. You could even provide a plate for at the request of the buyer.

I WANT ONE NOW STEF!!! I'm gonna ceramic coat it bright silver to match my Turbo manifold on the other side because you know they have to match! It's gonna be SO hard to drive around for a few hundred miles without boosting. Maybe I'll let someone else do it for me.:)

EGR is a must if you ask me. Older cars will have a hard time getting through the sniffer test, and newer ones will get a CEL. Switching out the intake manifold every year is too much work.

Vac ports aren't too big of a deal since vac blocks are pretty cheap and look cool.

And you would be wrong. i think if you can make it an option that would be best.

If you newbies wait a week maybe they will post pics of my 1.6 mani :)

money sure talks dont it :)

Surely this thing is has been to the dyno by now. Any updates on the intake manifold?

The 1.8L manifold has not been to the dyno yet. Someone else is testing the 1.6L manifold though. I feel your frustration though. Tim is back in school now and is getting the NC wrapped up. We need to clone him and Corky so that we can gets things done faster. :)

Here are photos of the latest 1.6L Manifold.
Stephanie

roughly how much longer till we can buy them?

that looks so sexy, cant wait to buy one

+1110000000000000

i am very interested in how this goes. i really hope you come up with a cracker of a part. will definitly be purchasing in the near future. hope you are able to do a flow test and see how many cfm it can flow.

+1.

I sooooooo want!

hey brad, your manifold looks done!

http://www.bellengineering.net/templ...e/P2015580.JPG

http://www.bellengineering.net/templ...e/P2015580.JPG

It is! I have prettier pictures I will post tomorrow.
Stephanie

what happened to the tappered design?

i can buys now? LInk me please so i can purchase.

The legs are tapered. If I am not understanding your question, let me know.
Stephanie

As soon as they have been tested, we will put them up for sale on the web. We just want to make sure there are not any major problems first.

The nicer photos are going up right now.

What's the extra bracket on the underside for?

Awesome! Any Ideas on price yet?

Gonna deffinately need more vacuum port's. Brainy, what's that thingy you used on your's?

I used a vacuum block, much like this from JGStools.com: http://jgsturbo.com/ta055.jpg

http://jgsturbo.com/mx5bp.html

I should know more next week on the price. I can tell you for sure the 1.6L piece will be more expensive than the 1.8L intake manifold.

More vacuum ports can be added, that is not a problem. Or you can use a vacuum port like brain did.
Stephanie

Cool, I would like atleast 2 more.

Brake booster
FRP
MS
BOV
Boost gauge

Obviously you could run T's for some but Id rather have them all seperate.

by tappered i mean the actual plenum

how much more are we talking tho? like the 1.8 manifold is 460$ we talking 560$? or like 700$?

No that is not tapered. We have not have a tapered on yet.
Stephanie

Probably between $575 and $625 for the 1.6L. I should have final numbers later this week.
Stephanie

Well that about knocked that out of the water for me for some time lol

lol you had to kind of expect that cost.. the only other one on the market is about that price if not higher. :) Requires a great deal of labor due to the fuel injectors vs the 1.8.

which is why some of us opted to hack up a stock IM and weld to that....

I'm wondering if BEGi wouldn't be willing to use the plenum and runners they are using and just weld to a cut IM like mine. Possibly a cost savings/time savings for both parties.

I know since I wanted those 45° runners and other factors mine wasn't as simple/easy...

I would send them my stock one if it made it cheaper for sure

+1 billion.

I will ask Tim and see what he says. The 45 degree runners would not be any less expensive. If it were a straight runner, most likely. Let me see what he says tomorrow. We might be able to do two version of the 1.6L manifold.
Stephanie

Its nice but i wanna see some #'s Seems to me unless we go with a bigger throttlebody then the benefits will be awash hey scot im feeling lazy shoot me towards what u did with ur IM man :P

The TB is not a restriction for flow; if it were the case, your IC and compressor outlet would be hell on the system.

there's a thread in BEGi's section about my IM....

Now when you say a bigger throttle body... do you mean one that can .. consume an entire bottle of fuze? :eek5:

http://i41.tinypic.com/2zyfxgk.jpg

Props to Corky and his team on the worksmanship. This thing is really gorgeous. Once I solve this random issue w/ the car, I'll strap this thing on the dyno.

http://i44.tinypic.com/1675ncy.jpg

larger for those who like to see....

Ok we saw. It's really nice and big but; would you please tell what throttlebody is that?

Thanks

Wait.. so you saw?

Its a 70mm mustang TB. Power products or something along those lines.
