Who makes a good variable vane turbo?

[nukeduster]

I was looking at turbos and can't realy seem to find any readily available. Any ideas?

Failing that, I intend to pick up a garrett gt3582r with a .63/.70 a/r... once my income becomes more stable at least :lol:

Right now everyone has one. None of them are very strong at all, since the variable vane system is kind of fragile.

thats a pretty nice turbo, you going manual finally too?!

I dont know many people with them. They are pretty rare. Ive been trying to source another company for a bigger turbof or my car but all I can find is aerodyne (dead company/dead owner), and BorgWarner, which is too idustrial and I cant get any info from them. BW builds the variable vane turbos for the new Porsche 997.

They just get too hot, which is why variable vane turbos are somehwta required to be built of of mroe heat resistant material. BW uses some aerospace material but doesnt list it's content specifically.

GT35r does spool fast though. Dual ball bearings. What displacement is your car?

[nukeduster]

2.5L.. but the m20 motor has been known to be able to spool t4 cased turbos pretty quickly, it flows as though its a much larger displacement motor.

it should be right within the efficiency threshold i'm looking for by its compressor map.

Here's a link to some BorgWarner turbos, but I didnt see any variable vanes mentioned. But check out this extended compressor side inducer.

wheres teh link? lol

[triggrhaapi]

Garrett just announced that they are going to be making some T3 housing based variable vane turbos for diesel applications soon using their GT/R series dual ball bearing center sections. Look for those in more bitey gas engine area ratios pretty soon as well. That will >*

Where'd my link go? Lame.


Trig, that makes me very happy. it allows me to compromise between variabel vanes and the aweosme ownage of hopefully a larger DBB turbo

I don't know whats all the hype about it, seriously, i worked a little stint on diesel engines and turbos, and i can see that fully function on a big truck 2500 or bigger but i don't think of myself applying that to any of my cars until they can deal with heat issues. If you can do the homework, match the turbo to your car, with the allotted aftermarket stuff you wish to apply to it, you can find amazing results without the high tech variable coolness. No doubt that the design is very cool, but its not a mass market thing, and to find an application for your car would exhaust your funds. A gt35 would be good but also would a gt30. The most common misconception with forced induced cars is that people tend to throw whatever turbo they can find and expect superior results (remember some people not all). Yes you can find some good results, but at a cost of rpm to boost, laggy, not enough rpm to fully see the potential, or blown engine or whatever, i have learned from my past cars that its really important to really match the turbine to fully use every bit of bore and stroke that my car can produce and be efficient.

Variable technology has been a great design in diesel engines, but i don't think about applying it to any of my cars in the future Unless its cheap and i don't see any problems associated with the application. Good luck on finding one, and if you do ,keep me posted, i would like to know how it would apply to your platform. And the results.

Cheers.

no need for any special turbo. a properly sized garrett gt series turbo will be more than enough.
