Title: Check out my new exhaust manifold head flanges
Post by: 935racer on November 11, 2006, 10:19:08 pm

Note how they go from the stock oval port on one side and than are CNC milled out to the circle size of the primaries. 8)

Nice!

  I also see an almost done intake mani lurking in the background of the last picture!

Yeah intake manifold is actually a jig piece for when I was playing with runner length to tune the manifolds for the best balance for low end vs. high boost/flow.  You can see the results of my new bead roller on the end of the transition piece there though 8)

is the exhaust piping larger than the round ports?  Just curious if you're gonna have a step to reduce potential back flow (ala Bells 4-stroke performance tuning) or is this not needed in turbo manifolds?

Wowie, that's SICK!  Are these going to be for the D.I.Y.'ers to make their own manifolds?

Jtanguay, Thanks man, start putting the change in a jar :D

ezekiel, yes there is a step and its on the oval side of the flange, the circle side for the primaries is perfectly matched.

Benjamin, thanks man :D

lord_verminaard, Thanks and yes these will absolutey be available for the DIY'er, as well as the intake manifod flange, and different turbo inlet and outlet flanges, and collectors, givin these arent gonna be as cheap as just some off the shelf laser cut vw 8v flanges, but as you can see these arent your ordinary flanges. We have been working really hard to make the best manifolds possible, this flange is just a taste of whats comming 8)

Trevor, thanks mang, start saving that extra skrilla, and you'll get what you want.

Heres a screen shot of my soon to be here intake manifold flanges for 1.6, I don't have a screen shot for the 1.9 version but you get the idea. They will be made from .5" 6061 almuinum.

1.6:

 I made some narrow angle 4-1 merge collectors for t3 style turbos and vnt style turbos, gt series collectors are on the way. These were all cut on a mill anf fit perfectly, sure as heck can make them much better than this.

Here is the collector I made for a t3 turbo inlet (rectangular inlet/port):

And the vnt style (circle port/inlet):

We made a jig for the collectors for 100% perfect repeatability.

if you need anyone to test these new manifolds, let me know, i'll do it for the small nominal fee of letting me keep them  :twisted:

DIY eh? SO I could buy all the pre cut parts and weld it  myself?? Sweet.

Were you ever going to get K24 flanges?

Any Ballpark Ideas of how much money Im going to have to put forth for these....

...my kids already had a few good Christmases....this will come out of the present fund..

"No kids...Santa thought you were all rotton...but I was good...Look at the cool manifolds he brought me" :D

yessssssss daddy's earned it!!!

this is serious stuff... our engines will operate so much better when each individual port gets exactly the same flow as another... wow i'm so glad that the diesel community is made up of geniuses!!!

Even if I had money it wouldn't last very long with these kind of products. Awesome work

Holy ******************************. I'm guessing these are already gasket matched leaving only the head to be ported, right?

Fantastic work btw. I'd buy one of the DIY kit just to hang it in my bedroom.

Well I will be selling the collectors, turbo inlet flanges, turbo outlet flanges, and head flanges. So the primaries are up to you. Unless you are putting it on something other than a golf/jetta/passat you won't be able to come up with anything better than what I will have pre made, but I'm sure it will cost less!

No doubt! These will be must haves for people pushing big power. :twisted:

Absolutely, the 9cm holset housing is just a regular t3 flange which is the same as the t3 collectors I already make. The split turbine like for the hx35's will be comming soon as well as GT series collectors.

Yes all you need to do is port the head. If you like these flanges wait until you see the manifolds. Art pieces no doubt, but the flanges really are beautiful I literally have one as a centerpiece for dinner conversation at my place, I just hide it when the ladies come over :roll:

The right kind of ladies think that stuff is cool. My wife installed her own full long tube exhaust (Mustang GT) and thinks the flanges look great.


Bummer...so you wont just sell me the peices. Oh well..guess Ill have to just let you weld it. :D

So what about that K24 flange?

The k24/t3 adapter is in the works, should probably see those around christmas time.
