I've made a substantial "dent" in the work on the 32V TT system. I've completed the driver's side manifold and I am onto the passenger side this week. Once those units come back from welding I can start on the downpipe fabrication. This is the trickiest part of this whole process. Manifold fabrication is not an easy task and you have to be very patient. The new style manifolding turned out really nice and is a large departure from the older systems. I believe it will work very, very well. It is a visual eye-feast as well! It has been designed to deliver maximum exhaust energy to each turbine with minimum of surface area. I will be giving regular updates, but there will be no more photographs. The "leg" shots are all you get for now unitil I am done.

I'll be into tall-cotton once the manifolds and downpipes are in place...the rest is a gravy-train operation... well, sort of.

Trying to stay off here and remain focused on the work at hand.

John - I think your work is outstanding. You really know what you're doing with the turbos and I commend you for all your development. But why all the secrecy?

IIRC you had the same behavior when building Goldmember. You were afraid someone might steal your ideas. Well let me say that people are inherently lazy! I seriously doubt anyone would ever steal you ideas. But for the sake of argument let's say they did. So what? What is the likelihood that you would ever make kits for sale? I'd say slim to none. No offense, but you are a talented hot-rodder and not a businessman.

I've worked with many entrepreneurs that have had the same attitude. About every 7 to 10 years someone gets a great idea... but they can't tell anyone for fear of loosing the market. So they go ahead and go off the reservation and the next thing you know... yep... another Dog Washateria. In fact one just opened by my house called the Sham-pooch! I kid you not! They'll pour their entire life savings into this fate-be-known business and within 2, maybe 3 years it'll be boarded up and converted into a Dollar store with more crap that we don't need. But if they had just realized that there are very few original ideas anymore, and that more often than not, people will never act upon those ideas, they could have been shown the light that this was an ill-fated concept to begin with.

Now, I'm not saying your concept is ill-fated. Hardly! But if you prefer to develop your system in secrecy, then do it in total secrecy. Don't post at all. But if you're going to share, why not share completely. You might actually learn something in the process too. Just my $0.02.

X2 -

Get in the garage & keep working - don't come back without a dyno sheet.

I am suree he will share all when it is done :-)

He's just keeping some interest going, and to let us know he isn't asleep !

hunting down a pair of variable-vane turbos, no doubt!

If we didn't give John **** about these threads, what fun would this place be? Consider it a nice way to keep bumping the topic up.

Whoa... Deja vu!

Earlier in another tread, I’ve asked him why he didn’t consider the variable vane turbos (VNT style), but there was no response. Maybe that’s exactly what he’s using. He refers to the S4 TT turbos as “compact, mighty and with a lot of flow”. Unless I’m missing something this is a pretty good description of a variable vane turbo. Dodge used them on the early 90’s Daytona Iroc and VW have been using them on the TDI models since the later 90’s. My commuter car is a TDI Jetta so I know exactly what the attraction of a turbo like this is. They are essentially 2 turbos in one. Works like a sequential pair of turbos but in one single design. Using a pair of these units will be the equivalent of having 4 conventional (standard housing) turbos on the S4. Two small ones for low rpm boost and 2 large ones for high rpms. All this with only 2 turbos instead of 4. Controlling the vanes will require some designing but it can be done and it IS the ultimate way of boosting a 928. A design like this will combine the strengths of all the boosting methods without the inherited negatives.

Oh be nice - John Speake is new to this computer thing

Andrew...I've already filed with State of KY and the IRS. My LLC is active as of 2 months ago. Many people are very interested and John Speake hit the nail on the head.

I don't think anyone is really selling any variable vane turbos right now for performance applications (there are some in trucks).

Aerodyne used to make one, and Corky Bell talked it up a lot in his book (wonder how much of a cut they were giving him), but the turbo didn't quite live up to expectations and had a lot of problems and I think they're since gone out of business.

But people are definately woking on them. I'm sure once they get them sorted out it'll be a great technology. But right now it's pretty unproven, although I think Porsche is (is going to?) use something similar on the new 911 turbo.

Anyways, IIRC John has already said he's using Garrett turbos.

I wish you, your dog, and your cat the best of luck.
