The castings, I was told I would have last Friday, did not turn out. Corky said something about the metal was too cold when poured, so they have to redo it. I will get an updated ETA from him.
Stephanie

You guys need to stop screwing around and invest in your own in house foundry. Seriously.

The Foundry just said they are pouring new ones today.
Stephanie

In the time its taken to do this, I have gone through 2 miatas, blown two built engines and am in the process of parting out my msm and buying another NA....

sweet

Look what showed up last week!

The new manifold is almost build and ready for in house testing. In building the new manifold we have determined that the castings will work well and make it significantly faster to produce than a sheet metal manifold. So, more castings have been ordered! :D
Stephanie

Look like some kind of larvae, interested to see finished product.

Any pricing info yet?

Will know more later this week, once I have the final time to fabricate it.
Stephanie

reminds me of this lol

I just had a brilliant idea

connect the plenum to the runners underneath and add a set of butterfly valves that....

nevermind.

ETA on dyno data?

you're onto something. long runners for mid-range and the butterflys open at 6-7k. Like the GSR manifold.

I think he's talking about the NB VICS intake manifold. Lol..

It's almost been a week.

Any news?

In a thread that's over 3 years old you're worried about not getting an update in the last week?

:noob:

:laugh:


You must be new to Begi.

:noob:

nah, that doesn't use different main runners. it just leverages helmholz resonance.

unless you've done the "mod"...

before:

after
http://www.targamiata.com/images_lrg/img_3643.jpg

It has been tested, but I have not been in the office to see the results.
I will do that tomorrow!

And don't give me no crap about the color either! It is "BEGi Yellow". :)
Stephanie

nice heat shielding! more info?

Get to those dynos yet?

why you gotta tease us like this

Monthly thread bump... I'm guessing it didn't make they power they were looking for so they're hoping we all forget about it :) Or... is Stephanie on an extended vacation and still hasn't seen the results :)

fail

..?

bump for results, so i don't have to make a franken-honda manifold.

OMG! More stuff has fallen into the stewart paradox. Don't worry, the results will be posted tomorrow... forever.

NOOOOOOOOOOOOOOOOOOO! :sad2:

2 weeks

Another month.

Any news?

Any news?

Our straight tube guy works well above 5000 rpm. Adds a nice 5 to 8%. However, about 3 or 4 % is lost between 4,000 revs and 5,000 revs.

I now have more respect for Mazda's intake manifold designer.

I am absolutely certain my next version will work perfectly everywhere, everywhere, everywhere, everywhere............

Corky

Screw that. Just make a badass intake manifold for the 300+++ HP club not these 200hp plebes.

This!

:)

Any updates on the progress?

Either they don't care about the cheapass miata crowd, or they found it's too difficult to put all the pieces in the same box at the same time.

Fu the cheapass crowd. There are so many people on here with built motors. Big powa glowwwyuyy!!

this

I think Il just stick with my 01 manifold.

4-5yr old thread bump-

So after searching, and finding only a few threads with very little legitimate information (if there is info ive missed please share it with me) I am trying to figure out whether the above manifold mentioned by Corky is the current version, or if a more efficient manifold has been designed.

Also, the description for the manifold listed on the site is very vague in regards to performance of the manifold. You say the lower HP guys will lost HP and that more than 270hp is needed to see gains from the manifold. Where in the RPM range are those gains typically seen? And what sort of gains are we looking at?

The manifold mentioned by me above, it is not in production. The bent runner manifold.....

The manifold mentioned by Corky, the straight runner, is in production. That is the only one we produce. The gains you will see with the manifold are usually 4500-5000 rpm to the revlimiter. Depending on the engine and modifications, gains are usually 20+ horsepower. We have always tested and seen about a 20 hp gain over a stock intake manifold. That said, I don't have a lot of dyno sheets for this particular part. But I've never seen less than 20 hp.
Hope it helps,
Stephanie

So you definitely have a few then.
Let's see them.

My server crashed a few weeks ago, and dyno sheets is one of the folders not backed up along with some photos. I will see if I can get the data off the drive. The last dyno sheet that was sent to me, and the one I am looking for, was a friend of Braineak's. Brad? It was a 1.6L, GT2560 running 14 psi - if I remember the details. I know it was posted on the forum back in early to mid 2009.
Stephanie

was a 1.6L running a 2871

https://www.miataturbo.net/attachmen...ine=1455911079


trying to find the before. or maybe this was the before...

Any explanation for the drop ~4700rpm?

yeha this was the before, i know he hit 261rwhp when we went back to the dyno with no other changes:

https://www.miataturbo.net/dynos-tim...261rwhp-35950/

boost control issues. this was back on MS1 and it was running open loop EBC that wasn't playing nicely on the dyno. it was tuned agressively to help spool on street, but on that tdyno it was causing it to spike.

so 247 to 261 is still not 20
and I'm assuming that was with everything else completely unchanged?

just slapped it on and went back to dyno.

I want BEGi to find the mold to the old cast one and release it again. That IM was a winner.

I could have sworn power was 270 ish hp. I will still try and retrieve it, I know there is a copy somewhere here. Maybe I am thinking of another car as I was wrong with the turbo. It was 6 years ago! LOL. My apologies for being wrong. I will still try and retrieve it, I know there is a copy somewhere here. It's not on my old computer, so it must be a server file I need to retrieve.
Stephanie

I AGREE 100%!!!!!!

We have had a problem finding a quality aluminum foundry here in Texas to do these. The last two foundries sent us crap for castings. I will have to look out of state to see what I can find. We still have the pattern, so it's do-able if I can get around Corky and the foundry does not require pouring more than 10 pieces at a time.
Stephanie

^THIS^

here I found it:


https://www.miataturbo.net/attachmen...ine=1455989340

https://www.miataturbo.net/attachmen...ine=1455989340

i have the log file, it's showing a peak of about 220kPa, dropping to 200kPa at redline.

so about 17psi dropping to 14psi.

so it gains topend and sacrifices lowend. looks about right
and this is vs the 1.6 mani
I wonder if it would be better than a flattop

yeah this was a on 1.6L.

this was a really primative build.

MS1. batch fueling. 550cc Rx7 injectors. Open loop EBC that wasn't working well.

I think this thing had potential for huge gains up top, but he decided to sell it shortly after this.

Yeah, It's pretty hard to be relevant in today's technology and marketplace when all the "results" are from 7 years ago using technology most here don't even use anymore because it's outdated and retired.

17psi for 230wtq would get laughed at today.

if they bring the old one back I hope someone does proper, modern, testing.
Kinda hard to spend $700 on a part that may or may not make another 15hp

One day I may do testing between my begi cast manifold and a flat top.

that thing was awesome:

https://www.miataturbo.net/attachmen...ine=1456001509

99 motor, swapped to cast BEGI IM -- no other changes. Others had similar results, even the FM testing back in the day showed major gains.
