Mike, sorry maybe it doesnt make it on an evo, there are no 1200hp evos......but Full-Race could probably do it. Other people seem to be making due just fine with these turbos on our cars, maybe YOU are doing something wrong? How many of us are going to be making 9-1000whp and pushing 50 psi through a turbo, a fraction of one percent.

So you know what mike, we don't care the slightest that you and all of your "tuning" ability was able to blow up a couple at a strip, you have one vendor build your motors, another tuner tune your cars, then somebody else drive your cars, I really don't think your comments here are needed!

What are you doing in this thread anyway, you are aware all of your "mentors" think this thread is a gathering for witches since we are talking about physical properties that they refuse to believe exists.

Geoff- What borg would you recommend that has similar spool/response of a 35r sized turbo(hopefully better) but more potential up top?

HTA3586r?

 

the 83-75 w/ 1.10 a/r seems to be working very well on this 2.3L, so that is my choice at the moment for the 35R+ size turbo in twinscroll config

get us one!!!

 

I wasn't asking your worthless opinion. If you would pay closer attention you would realize that 99% of folks on this board don't take you seriously.

 

Thanks for the link. I'll read through my copy tonight.

 

Feel free to scan it and post it up. At least it will end this topic once and for all.

 

Actually your WRONG.. Buschur Builds my motors , Crispeed tunes it and I drove my black car always.. you made the 1200hp comment so all i said is i would buy it.. So let me ask you.. Who Builds their own motor, tunes their own car and drives their own car that runs 8's?? NOBODY w/ an EVO..

I was doing nothing wrong.. I called Several BW dealers when i was in the market for a BW turbo and they told me straight forward DO NOT EXPECT THE TURBO TO LIVE AT 50+ psi with a 270 thrust bearing.. i wasnt doing anything wrong.. Im not going to throw anyone under the bus but i spoke with sponsored RACERS, 7 Second Car owners that use BW and they said " sorry we dont have anything we could be sure would last at those boost levels from BW..


Now lastly i will say BW has its place even possibly in the MITSU market on lower boost levels.. Dont go throwing around 1200hp #'s on an Evo forum and think those turbos will last 5 passes at that HP and boost level..

 

+1

Seriously , its tiresome listening to a parrot who just rides everyone elses knowledge and has no REAL WORLD TESTING on his own..

 

dont forget to search ASME, thats where the best papers i found came from.

 

crcain, bolio,

I can't say I've personally witnessed or ran any back-to-back test of VTF and VOF housings of the same area or A/R. In our line-up there are a couple which are the same so I suppose the testing could be performed; but the ones that come to mind right off are S500 model units with 110-120mm turbine / 120-132mm compressor sizes (much bigger than what we are working with here).
I can possibly find out what sort of testing was performed but it would have been WAY before my time when the housings became widely used in the industry (1970's?). I'm sure the SAE paper link posted would have lots of good information included that will go in depth beyond my abilities...

As far as differences in power capabilities up top; I would assume there's not much measurable difference between the two... I've had this question brought up before which I've only been able to answer with my own intuition. I'll try talking to some of the other guys to see if I can get some more insight and let everyone know what I learn.

Can someone clarify this. Why would they design their Compressor wheel range to operate up to 50psi in some cases if the bearing system isn't up to the task ?

 

Feel free to link some, 'cause I couldn't find any......

 

Mike,

Let me first off apologize that you experienced failures while running our turbos...

There are obviously several questions that need to be answered with the problems you experienced and I'm not sure this is the correct forum to attempt to answer all of them. I'm not going to tell you something is wrong with your set-up because honestly, I don't know anything about it and I won't even attempt it... I will tell you that I do know turbos and if you've experience failures, something was wrong. That "wrong" could be many different things or any combination of several. I don't know who at BorgWarner inspected your turbo and my guess would be no one. I'm not trying to deny that someone looked at it, but I don't think anyone at BorgWarner did as I'm typically the guy who would look at any performance, or AirWerks units that would be returned.

Your concerns seem like they may be a little distracting to what this particular thread is trying to accomplish... so if you're interested, I would like to possibly talk to you over the phone sometime to see if I can help figure out what the problem was. I'm not real sure how to get in touch with you though, can I contact you through your website? I realize that the damage is already done and you may not be interested... If that's the case, I'll try to address all your concerns on this thread for everyone else's interest, but it will take some time. I'm trying to post on here as I have "spare time" and I would have to tackle your questions in "smaller bites". Just let me know what you would like to do and we'll go from there...

- Kurt

 

I do all the real world testing I can afford......three garret GT3XXXR variants, on three different manifolds, with four different hotsides,3 different sets of cams, 3 different wastegate setups, 2 intercoolers.... I'd say I have done more testing via combination of parts than the average evo owner, not as much as any vendor, but more than most

I am not a vendor, I am not a tuner, I am an enthusiast, a passionate one

If I had somebody give me a bunch of money to open up a shop, I could do plenty of testing, real estate/dynos are expensive.
