Where is the ported TIII manifold thread?

[turbovanman²]

Someone posted up about porting TIII manifolds and removing the "ears" that hang down on the ports and there was a big discussion on it. I've searched but can't find it, :(

Hope these help.

Thanks, I guess it must have been moved or deleted? :(

I think you were thinking of somewhere else. :D :p

[Turbo224]

Haha, actually not. We had a big discussion about my porting in another thread a week or two ago where a few people thought taking away the bumps in the runner was a bad idea. It didn't exactly get heated, but a few people had some strong opinions about it. Anyways, the thread must have been deleted because neither Simon or myself could find it again.

so it is bad to cut the little ears off?

[moparzrule]

I think I was in that thread? I remember posted about them anyway. I keep the ears in because of port velocity. I make them smaller, but don't take them out completely. It's not all about flow, velocity is key as well. Having the ears in there will not hurt flow either and will keep velocity maxxed. It's a win/win.
The 16V has 2 semi seperated exhaust ports coming out of the head. The manifold must maintain this semi-seperated theme for port velocity. Basically I make the manifold a continuation of the port in the head, this is what you want. The ears is what give those ports directionality, without the ears the exhaust doesn't know where to go it just fills up the log and tries to find a way out, very bad for velocity and will kill your turbo spoolup. My manifolds typically increase turbo spoolup about 200-300 RPM.

Nope, not that one.

Yes, you were in it as well Matt, :eyebrows:

Not sure where it went?

Anyhow, its back so thats GREAAAAAAAAAAT. I just wanted to show a buddy the manifold and see what he thought of removing the ears. Tyler pointed out Wallace removes them aswell.

IMO that stands for In My Opinion guys, there is no real gain in removing the ears. A fully ported head (at least mine that was done by someone I trust to do porting and has done dozens of 2.2 heads) still has the ears so cutting them from the manifold doesn't make sense.

Here is a pic of the ported exhaust side, the scribe line is the gasket size. You could probably open the manifold and the head that big but why would you?:confused:

The only reason to remove them is its easier and faster to open up the manifold so theres no reversion, IE make it bigger so the exhaust doesn't hit a brick wall. Sure you could take the time to match it perfectly but that does take effort, :eyebrows:

I've bought two of the ported TIII manifolds from FWDP and one from LWP and they were all identical. All were opened up to the gasket, with the port dividers (ears) removed. Just thought I'd throw that out there FYI.

I take the manifold to the gasket on the sides and top, but still leave the ear there because it makes the manifold a continuation of the port and points the exhaust in the right direction instead of letting it blow everywhere.
For flow, yes it will show higher numbers on a bench perhaps and it's easier to just gasket match. But for flow AND velocity, leave the ears. We all know that our heads need velocity and not just peak flow numbers, I use the same principle when I port manifolds as well.
Nor surprise to me on the FWD manifold, but the LWP manifold is a surprise that they remove the ears because even in their porting description they same they believe in not only porting for max flow but max velocity. Apparently this only applies to head porting though :(

Speaking of TIII exhaust manifold. I have this custom piece in my possession. Bought it because it looks pretty, I don't even have a TIII car.

Where did you get that?

How much?

[iTurbo]

Hey that's pretty cool. That would have made it a lot easier for me to put the TII turbo on my R/T. Would have been able to use my 3" TU swingvalve too.

[tryingbe]

The other site. Don't remember how much... I don't even remember who I bought it from or when..

If anybody wants it, make me an offer I can't refuse.
