The videos make the collector construction clear.

Get a photobucket, imageshack account. It'll be way faster for us all.

That mani looks great though. I wonder how well they perform. Sure they do well.

I dunno. That's pretty bold not pointing the gases from 1 and 4 into the turbo instead of at each other...

Are you happy with the construction? T25 flange?

JasonC SBB

Yes I'm quite pleased.
I will port the part where the runners enter the T25 flange, the gases see a step. Shouldn't be too hard.

But first, I have to get my BMW running. The guy who will mod the BEGI downpipe to mate with the new turbo location will take 3 days. If I don't have a 2nd car, I can't visit him to check on his progress. Gotta send the BMW head out for porting and a valve job.

So y8s, where should I put thermal relief cuts?

beerslurpy

Yeah 2nd cars kick ***. Grats on the nice manifold. What size turbo?

So the idea with this manifold is to have a "best of both worlds" between log type and tubular/ram horn type?

Looks really good!

Don't do relief cuts.

I've had two of those manifolds, a 1.6 and a 1.8...

On the first one (1.6), I made relief cuts and it cracked regularily. John at ETD said it was the cuts causing it.

I got a second one for my 1.8, didn't make any cuts and it is fine, no cracks.

yeah I dont know that you need relief cuts (or that I did heh!)

The pipes aren't a single piece like a cast manifold so there is room for expansion and bending.

The thing I had an issue with on my ETD was flange flatness. You may want to have both flanges skimmed to get them flat again.

I admit I'm a little jealous. I bet yours flows as good or better than mine and weighs about half as much.

JasonC SBB

I called em and they said they had way more cracking with cut manifolds than those without. They also said they heat cycle 'em and re-skim 'em flat.

Don't be jealous. My turbo is like Peewee Herman to your John Holmes special.

I'll be porting the turbo side flange a bit, the gases see a step going from the tubes to the flange.

kotomile the idea is to NOT FKN have the gases turn sharp corners like almost every other cast mani out there.

looking forward to data...
Hurry up!

Nice manifold!

Nice that they do that now.

My head flange was about as straight as a politician.

Jason,

Any data on the new manifold? How does it compare to the AVO or better yet with the new Begi "directed pulse" cast manifold?

Jason, sent you a PM. You haven't posted in a while. Hopefully you are still around.

I am considering this manifold and would like to know your results as well.

Thanks,

Looks good, guess you are not running an external waste gate. you think it would be possible to add one to this type of header?

I'm going to be using a tial 38mm.

They offer that manifold with an external wastegate flange added on. You can see it in the pictures.

I've received a couple of PM's but nothing from Jason. Yep, still around. The ETD looks interesting and I'm curious about the benefits from a design standpoint. But if I ever upgrade I'm probably going to lean towards an "Absurdflow" mani from TurboTim. That boy can weld!! Just take a look at Paul's setup.

Thanks Riccardo!

I'm going to make a couple manifolds in the next month or so. That way if someone wants one they don't have to wait. Bla bla bla. I jsut feel like building two.
