Re: Borg Warner Turbos
Latest word from Raffi at Full-Race is tht pricing may be out at the end of sema, but it could also be after thanksgiving.
:( If it is truely going to be that long, than I will be just sticking with the 84-75 I have because I need to start making some progress. |

Lame. Don't do it!!

Re: Borg Warner Turbos
If you have to ask about the pricing, then you can't afford it. :)

First pricing I've see listed. The one I would have been interested in which is the 8374 w/ divided T4 and internal WG is around $3000 (part number 179357). So yup, I'll just be sticking with the 84-75 I have now, im not ballin like that :D haha |
Re: Borg Warner Turbos
Geebuz. Still cool, hopefully pricing comes down a bit eventually.

Re: Borg Warner Turbos
Full Race got their site updated a little bit with more info. Click on the turbo in the bar graph for pricing, comp maps, more info etc.

Re: Borg Warner Turbos
I'm confused by those numbers, a 67mm only rated to 49lb/min?
|
Re: Borg Warner Turbos
that's 67mm exducer. They name their turbos different than PTE. PTE uses comp inducer and turbine exducer (i.e. 6265)
BW uses comp exducer and turbine inducer (i.e. 83-74) So the 67mm turbo you are looking at, would be more commonly referred to as a 53mm turbo (that's the inducer). The 83-74 (a 62mm turbo) they rated at 79lb/min!!! And the real 67mm turbo (91-80) they've rated at 94lb/min. |
Re: Borg Warner Turbos
^Thanks for clearing that up, I would expect that 53mm turbo then to do 55+lb/min.

Re: Borg Warner Turbos
cool vid on the new efr stuff. amazing how much r&d goes into these before ever even being bolted onto a vehicle, and the testing they do also.
http://www.youtube.com/watch?v=wfuE6xiij9g&hd=1 Some info from Geoff @ Full Race that I thought was useful. If you go bigger on the compressor that is the same thing as going smaller on the turbine. I put up a bunch of posts explaining the U/C ratio of Compressor OD / Turbine Wheel OD in that big road racing turbo thread... basically divide the compressor OD by the turbine OD - an optimal match will be in the neighborhood of 1.09-1.18 whereas a mismatch turbo will be 1.18+... Also keep in mind that a small a/r will have low turbine efficiency at low flow rates, and higher turbine efficiency at higher flow rates. Conversely the large a/r will have high turbine efficiency at low flow rates and lower at high flow rates... 6blade compressor wheel -- ideal match ratio of ~1.14-1.24 7blade compressor wheel -- ideal match ratio of ~1.09-1.18 |

Re: Borg Warner Turbos
Figured I'd share some results I found from someone running my same 61mm turbo (BW S300sx 84-75) on a Supra with a .88AR T4 open exhaust housing and 264/264 cams. Thought they were some pretty good numbers for a 61mm.

Re: Borg Warner Turbos
Those seem like great numbers, I wonder how much is due to displacement.
Vassil made 725whp (DD) at 32 psi on a 2.0L |
Re: Borg Warner Turbos
yeah that torque takes off and the hp takes over, very nice

Re: Borg Warner Turbos
The EFR turbos are fantastic. I got to see some of the first cars at Full-Race that had these turbo's and I was super impressed. Here is a video of a friend from AZ that has one on his fully built RSX. Also not sure if you can see the links to the forum.

Re: Borg Warner Turbos
Any more info on these? Trying to learn about t4 TS stuff.

Re: Borg Warner Turbos
I need to jump into this thread...
My plan for spring is to go back to an internally gated setup, 90% sure I will be rocking the 7670 .92a/r BW EFR. I have spoken to a lot of people and it looks like its what I am looking for in terms of down low power and powerband, should have peak torque around 4k rpms. Most who have tried this one on Evos say its a stock turbo on steroids feel, can't wait to try it out. I have been very skeptical of BW turbos for a while, ever since they released the EFR's but almost every turbo in the top 5 for world time attack runs an EFR now. I have tried everything else, mind as well try this right? Here is an Evo X comparison (2.2L motor) of the 7670 EFR vs the 9180 EFR http://i950.photobucket.com/albums/a...psf8eedb19.jpg |
