With all this talk of upgraded twins and stuff, got me wondering. The aluminum part of the turbo intake has more bends than a snake. Just from looking at it, you'll see that they have to be in there. But what i'm thinking is, they don't need to be nearly as crooked as they are. Does anyone know someone who could produce an upgraded one to perhaps match the size of the new compressor inlets on the these upgraded twins running around? While smoothing out some of the nasty kinks?

If someone where to make a upgraded one, I would'nt mind spending $150ish on it, or maybe more.

Whats everyone else's thoughts on this? CJ

 

Good point, but because where it is located I doubt if one would be able to fab a pipe w/o a 90 deg bend. Turbo is facing the rear and you pretty much have to bend it twice. Plus there is no room in the engine bay with the twin to work around this.

 

After looking at it more closely, and taking some measurements, I think its very possiable. The narrowest point, between the rear intake and the fire wall, you still have roughly 2 1/2". The top most serious kink that is right next to the main wiring harness, there is between 2 1/2" and 3". This could be done pretty easily, if someone knew how to fab up some aluminum piping with a flange. Anyone know of a 3rd gen shop that could do it? CJ

 

Well, I talked to a guy tonight about it. (Turbojeff on the forum) He's a mechanical engineer who can make all sorts of stuff. He said it would cost right around $3000 to get it done. So basically, it would take right around 30 people@$100, or 20@$150. To be honest though, it would flow more. But how much is the question? So, should I talk to Jason, about doing a group buy?

I'll talk to Rob@Pineapple next week, to see how much hp he thinks an upgraded intake pipe would net us. CJ

 

Sounds interesting. Keep us posted.

 

Jeff knows his shiznit..he knows the engines extremely well.

And I've seen his work, too. He's got a really nice battery tray that he designed. Top quality. Oh..and I've also seen this nice barcode scanner that he designed.

I'm in...

 

Man you guys have me blushing.

The problem with FDs is that there aren't many of them. I do design all sorts of cool parts, injection molded plastic, cast aluminum, sheetmetal, but with tooling costs (molds) added in we need more than just 10 people to buy parts.

pp13bnos. The $3000 was tooling cost, there is part cost on top of that. Say we came up with some design for a cast part, you would need $3000 to have the pattern made and then have to pay for each part on top of that. So the parts are a little more spendy that you quoted. The more complicated a part gets, the higher the price.

Archanglex, I got the car out of the garage. Mine is back in it's home.

Ouch...that sucks.

Oh..and as long as you don't park it in the middle of the street, I'll be happy.

 

Well, maybe I'll see if I can make a one off, for my own car. Then post the results of it. It would be pretty cool, if we could pick up anouther 1/2lb of boost from it. What ever happens, I'll keep you guys posted. CJ

The battery trays are realy a work of art.

 

If you were to try a design change for the rear turbo inake... you may want to consider a 2-peice approach. I just pulled my motor yesterday w/the trans and D/P connected... The angle I had to achieve for clearance of the motor mount studs looked like 25 degrees... lets say. That left little room for the rear intake pipe to clear the firewall. Just my 2 cents..

 

I doubt, I'd make a two peice one. It just adds more complexity. Not to mention, the pipe is only held on by two 10mm nuts. When you're down there removing the downpipe to midpipe bolts, it would only take a second. But thanks for the ideas. CJ

 

How about something a little simpler like a mandrel bent SS exhaust pipe welded to a flange? Thats got to be cheaper then a cast item.

 

didnt kevin wyum make something like that at some point? also this may sound dumb, but why doe that intake pipe have to go up into the engine bay? maybe it can go under the car?

mike

 

I'll have to look into the SS idea. But it would be neat to have it ceramic coated to keep out heat a little more.

What I was thinking was getting an extra pipe, cutting off the flange, and the portion that connects to the stock rubber part of the intake. Then buy some aluminum 90 degree bends with different radius, and getting creative. I've done quite a few mandral bent exausts for cars over the years. I don't see why a project like this would be to difficult. Now....I just have to get good with welding aluminum.

BTW: If someone else allready did this, please let me know! I don't realy want to go through all this stuff unless I have to.

And, if anyone has an extra one laying around, let me know. Shoot me a PM with a price. Thanks, CJ

 

Ok, a friend of mine in RPNW was kind enough to give me one. (Thanks Dom.) Anyways, now i'm gonna track down some bends, and start playing and taking some measurements.

If anyone could be so kind to measure just how big the stock turbo housing is. You know, the compressor side. Please give me an exact measure ment as possible. I could do this on my own car, but that would require me to actually jack the car up. I'm hoping someone has a set of turbos in their garage or something, thats all.

Thanks, CJ

 

ask bryan at BNR about that one. he should know.

paul

 

Ok guys, did some boost tests on my car.

Profec B off .58bar (according to the p-fc)

Porfec on low I see .68

Profec on high I see .9

Hopefully the numbers will come up with the upgrade, without touching the Profec. I'll keep you guys posted on the results. CJ

 

Awesome job getting creative! Keep us updated...
