More 930 Headers - and now for something completely different ...

Thought I'd share one of our more unusual projects.
This fellow had some not so common build parameters:
> 1.63" primaries
> V-band turbo mount
> heat exchangers
> twin waste gates
> waste gate mufflers

Basic header design was our standard equal length primaries with merge collectors.
The WG mufflers had to exit under the car for max noise reduction.
Heat exchangers are the final version (can I get a hallelujah!) and are going into production now. The 1.5" version is also in production.
We'll probably produce a few waste gate mufflers as some tracks are cranking down the sound limits.
Gotta love it!

That header is pure porn!
They are now on my official want list.
Great work Brian.

Looks fantastic.

What kind of heater hose do you use on the aft part of the HE? It looks as itll run real close to the glowing red tubes.

Thank you! The heat exchanger design remains bolt-on so they can be removed if damaged or not needed. For ducting we recommend the orange high-temp SCAT tubing from the aircraft industry. That type hose has a wire slinky inside so you can turn it and it will hold shape which allows the hose to not touch the header pipes. I had that setup on the red rocket for a couple years and it worked flawlessly. You can also use metal pipe but that is much more expensive. We have fixtures now for just about any configuration imaginable so the cost for custom is coming down as the "custom" becomes "options". The set pictured was only a few hundred dollars more than our standard 930 headers.

Nice work as usual!

Do you have any of your standard 930 ones with heater boxes in stock? I have been wanting some since I got your muffler. Between some unexpected repairs and some new wheels, my budget for my 930 was shot. New Year new budget!

Do I have to re route any oil lines or any other items? I plan to do the install myself.

Can you source all new fasteners and those orange heater hoses? It would be great to have everything in box, its sucks having to stop a project midway to run out for odds and ends.

Sweet Brian! That customer must be running some serious Turbo to run two wastegates.

Actually the twin wastegates have less to do with engine output and much to do with boost control. The size is 38mm per bank on very short exit pipes at a good angle of flow. The boost will stay dead nuts on 1.0bar with no creep, flutter, or lag.

Thumbs up

I like it better than your single wastegate system, less clutter where the it meets the turbo.

Very nice Brian.
Is he pitting on a Garret Gt35r with one of those trick light weight cast stainless steel TIAL hot side housings with V band clamp attachment?

The new heat exchangers are looking good too

Agree, very nice. Be careful with the oil lines/headers on a factory slant, 505, the t-stat is in a different location, the std early oil line thing won't work. Even the braided line with my fabspeeds is suboptimal, fs is currently fabbing me a special line. If that doesn't work, I'll be selling a bunch of parts.
This is where headers that allow the factory oil lines are superior IMO.

factory oil lines are always superior.

Yes Jim this setup is for a TiAL stainless steel v-band turbo. We've done a few of these now and they work pretty good.

I designed my headers to use the OEM oil lines but really it is best to move them out of the way if possible. The headers are really close in a couple spots with no elegant way around it. The factory has 3 different versions of the late oil line as well which further complicates things. We use OEM back date oil lines as I'm not a fan of the inexpensive braided lines. They work but OEM is made for the application. To do the slant nose oil line back date you need to have the rubber hose portion custom made at a hose shop. Nice parts are not cheap but usually worth the extra effort and coin.

SCAT tubing can be supplied with nice ends on it if you know the length you need. Look here: Custom Ducts! The source for Aircraft Ducting
Company name is Custom Ducts.
Makes clamping much easier as the wire will come poking out on tubing without ends on it, making it a pain to deal with.

As for oil lines, I'm using the old backdated line but I had to bend it a little to get it to exit in the correct spot on my engine. Also, I have to be careful not to contact it every time I jack the car up. If I had it to do over again, I'd buy the Elephant Racing line that passes over the top of the tranny, but it's way overpriced.

Personally, I think the large braided lines are fine (good enough for NASCAR), the issue with the factory slant is the position of the t-stat. A simple remedy would be a rt angle end on both sides of the line, but what do I know....
Let's see if I can't get it fixed or else the winter sale starts.
