BorgWarner EFR Turbos

Makes me want to ditch my billet turbo, and get one of these. Sounds so sick, and advanced.

"All EFR turbochargers use Extended Tip Forged Milled Compressor Wheels ***AKA Billet Compressor Wheels*** These billet EFR compressor wheels are manufactured from forged aluminum for maximum strength and light weight, then CNC machined on a 6-axis CNC Mill. The The blade geometry utilizes State-of-the-Art aerodynamics that delivers efficiency, boost capability and surge limits beyond any turbo we have ever seen.

EFR turbo compressor housings incorporate an integrated BOV. Yes, you read that right - the BOV is a recirculating style *built-in* to the Compressor Housing. The major performance advantage in this design is that it redirects the high-pressure compressed air from the outlet of the compressor wheel -> right at the low-pressure inlet of the turbo. This helps to keep the turbo spooled between shifts and offers cost savings/convenience while keeping MAF-based engine mgt happy. With this in place, there is no need for a BOV or flange on the charge piping. Of course for the hardcore racers who want to use an external traditional BOV, the EFR line up has that as well.

For applications which use electronic boost control, an Electronic Boost Control Solenoid (EBCS) is integrated into the compressor housing. This solenoid is truly OEM quality and uses an industry standard fuel injector plug, making it easy to connecting to multiple boost control systems. Of course if the hardcore racers want to use an external solenoid OR a manual boost controller (without the integrated EBCS), that is very easy to do."

BW has been gaining popularity like crazy lately. In just about every car market.

I'll be running the S252, my friend has this on his VW and the spool is amazing!!! he had the garrett 50 trim and hated it.
some pics we took

Is this Borg Warner's release party to catch up to Garrett's 20-year old technology? :giggle:

Wow a BOV built into the compressor housing! The stock mitsubishi turbo in my almost 20 year old volvo has that! Way to be proud of something 20 years old Borg Warner.

It looks like their goal to make the cheap components as expensive as possible. I like the strategy of producing products that no one asked for.

Say what you want, BW turbos are a better bang for buck than Garrett imo

If you know what to look for you can have a 450hp turbo like s252 for $400 not really possible with garrett if you ask me.

True, way better bang for your buck and have held up very well from what I told. They perform the same--if not better than a Garrett while being non-BB is a feat I think.

Garrett bb<BW jb<Garrett jb

I have seen tests from completely different companies confirming them performing just as well as, and spooling just as quickly as, ball bearing garretts. When a JB performs like a BB that is an accomplishment IMO

Yep.. The BW stuff is actually very good..

Very good article -->http://www.motoiq.com/magazine_artic...ature-set.aspx

I will be giving a BW a try if my 15g ever gets boring or just gives up on life.

The new efrs are indeed ball bearing. I am going to get a 7670 twinscroll internal wastegate. The GTX35 is an alternative but would require two external wastegates.

I don't give too much of a shit about integrated bov but the Ti turbine plus billet wheel plus IWG plus twinscroll sounds like madness. Hopefully 35psi @ 3000rpm with flow up to 600hp of madness.

35psi @ 3k? lol pass that shit, don't mess up rotation

seems a bit optimistic, twin scrolls are the shit though.

Thank god faeflora left us that beautiful post :jerkit:


I'll be running a 6258 or 6758 in the summer. A little update on my hot side and I'll be golden.

I would never in a million years have guessed that a internal waste gate could keep up with a external, let alone be *better.

Oh they are great, no doubt.
But even if he figured out a way to get it to really hit that hard that soon he'd have to drive around on some 26" slicks or something....And then replace all driveline components past the engine.

would be fun to watch though.
esp if he broke out the sawzall again:giggle:

THIS


In all seriousness though, these things are going to be serious game changers for a lot of people and racing companies. When I read that Sierra Sierra was switching to EFR turbos I was pretty much nutted.

I can't wait to "clean up" and get all my *archaic* :giggle: turbo stuff sold and go with the future.

I'll more than likely be driving around on 225/50/15 DR's so I will enjoy the boost hit.
