Why doesn't Garrett or Borg make these for tuner applications?

Like the article says, these have been used since the early 1990's.....WTF dont we have them yet? Instant Torque/spool FTW For now there is no compromise, big power, big lag :facepalm:

Well seeing as how the article states that the turbo temperature problem was only solved in 2007 while working with porsche I would imagine it is a patented design that is hard to copy without infringement. My second guess would be that the materials would be cost prohibitive for most tuners and the limited run was judged to costly for profit

I've seen these but if a company like Garrett or BW could make them I think it would bring down prices quite a bit......and this totally disproves Ryan's theory of patents or whatever.

We do. You can buy a Borg-Warner BV50 (the 997TT turbo) from Borg today.

They cost just a little over five thousand dollars each.

Still interested?

Actually, maybe but it doesn't look like one would flow enough for what I'm looking for. :vash:

I cant find much detailed info on them I see where it looks like together they both flow ~530 HP but is that indivdually or both together? You know of any reliabilty issues with these(certain amount of miles they typically last) or are they as good or better than your typical BW or Garrett?

Time to start scoping out the junkyards......

Have you looked at the Cummings VGT Turbo?

Few tuner shops can tune timing.

What makes you think they would be auccesful at VGT?

Wow, these look great. I just called the local Cummins dealer, got transfered between parts and service 8 times, literally, then left only to leave a voicemail. :facepalm: Not very impressive knowledge/customer service.

I've got a great tuner but I haven't ran this epiphany by him yet......I'm not saying this is a great/solid idea but if you could get full boost by 2500 rpms and make 600 whp would you say yes? ;)

No VGT diesel turbo is capable of withstanding the EGTs seen by gasoline engines. Diesel EGTs are 1200-1300*F max with short bursts to 1400*F on chipped trucks.

If you could hit a MAP at 2500rpm that happens to flow 650lb/min of air at redline...well, you'd need a different head at the least, lol. You're also highly likely to run into compressor surge because a variable geometry turbo is cool, but it's not going to give you that kind of output.

I just checked Ebay.. there are a few up for sale, both new and used...

Also a VGT for a Mitsu

$700??

It may be a better fit for a sub 2.0l engine

Just a guess.. I have not looked into it

I have a HUGE Cummings VGT to bolt on something, just have not decided what yet.
My buds and I call it the Basketball turbo....

If what Savington said is true.....this still wont work? Designed for a Mitsubishi Shogun(Diesel). I'm also having a hard time finding out what kind of power these diesel turbos could make on a gasoline engine. I see they make some massive torque but low hp. I'm assuming I can't just take the torque number from the vehicle the turbo is designed and for and assume the same torque will be made on the BP:giggle:

Anyone have any diesel to petrol conversion experience?

Sav's already explained why it won't work, boo. May want to listen to the guy, he knows what he's talking about.

Look at the Holset turbos. Originally intended for diesel, but they make lots of power and spool really well in gasoline applications.

If this is true, why do so many people run Holset's?

Ha, ginx
