Borg Warner unveils new super turbos

EFR Features & Benefits:

Low Inertia Turbine Wheel
Gamma-Ti Turbine wheel cuts turbine inertia by roughly 50%, dramatically improving turbo response. Turbine sizes range from 55mm to 80mm in Outside Diameter.

Heat Resistant Turbine Housings
Investment cast stainless steel turbine housings improve durability and offer an extremely smooth internal flow channel. Turbine housings have thin walls to reduce weight and thermal inertia.

High Turbine Efficiency
Superback and Fullback back-disk shapes offer very high efficiencies. The Superback shape adds a curved profile to the back-disk and has the effect of lowering centrifugal stress and permitting higher rotational speeds.

Enhanced Turbo Response
EFR Turbochargers use a dual-row ball bearing cartridge with ceramic balls and metal cage. This bearing system provides substantial friction reduction at low turbo speeds and in the process helps improve turbo response. Metal cage improves the durability of the ball bearing assembly.

Flexible Compressor Cover
The EFR turbo "large" cover has a dual-machined outlet, both for a hose connection and a v-band connection.

Simplified Installation
Integrated compressor recirculation valve (CRV) to help avoid compressor surge and backflow during a throttle lift event. This feature helps to simplify the installation task and lowers overall system install cost.

Forged Milled Compressor Wheels (FMW)
EFR turbos contain wheels that are fully milled from forged aluminum, commonly known as "billet". Cut from custom forgings, their strength exceeds that which is available from typical bar-stock and also exceeds the material properties of an aluminum casting.

Sensor mounting convenience
Speed sensor mounting provisions are also supplied on every compressor cover. Speed sensors are sold separately.

Boost Control Solenoid Valve (BCSV)
A boost control solenoid valve (BCSV) is included with every EFR turbo.

High Flow Wastegates
Purpose designed large wastegate ports give the wastegated EFR turbos the capability of handling the flow requirements of high performance applications.

Ease of Orientation
Turbo orientation flexibility is facilitated by the wastegate bracket to bearing housing mounting arrangement.

Adjustable Wastegate
The fabrication and installation task is simplified with wastegated EFR models that feature adjustable wastegates available in three different canister sizes.

All that shit and no ball bearing??

Dual row ceramic ball bearings (combined with titanium-aluminide wheels that are approximately 50% lighter too)

Good details on these turbos by someone from cosworth:

Game changer doesn't even begin to describe these.

The best part is the fact that you don't need to buy an external wastegate or BOV anymore and the boost control solenoid is already there, you just need electronics to run it. That right there is 600$ worth of stuff that you don't need for the power levels they're claiming...

 My bet is this is why Yan is suddenly selling his amazing FP hta68...

[John Hartman]

that is friggin cool by far!!

When people look up "win" in wikipedia, it should point to this thing.

When the cost comes down in a year or so, Imma get me summa dat!

[Remi Raymond]

Yeah.  Whatever I own in the near future is getting one of those put on it. I dont care if it's a dsm or a moped. Want.

[Carl Gould]

Damn. I know what turbo I'm saving up for next year.

My borg warner s366 feels so old !!!!

I like the wastegate position......should help spool-up..

Quote from Full Race update

Let’s start this update by talking about the excitement surrounding the new BorgWarner EFR turbos. The buzz has been a refreshing injection into a market segment that has been stagnant for some time now. BorgWarner’s new EFR lineup is one giant leap for all of us in the "go-fast" world. Full-Race has been working with BorgWarner for the last several months on these game-changing turbos. Long before the SEMA launch of this exciting product range, we were able to test the EFRs on a select few vehicles. We've been impressed with the materials, build quality, technology and service - They are everything you’d expect from a world-class company like BorgWarner... but we're even more impressed with the results:

    * Sierra Sierra's 2.2L 4 cylinder Mitsubishi Evo put down 700lb-ft of tq at only 5000rpm - and went on to destroy the track record at Buttonwillow CW13 - a full 2 seconds faster than their previously held track record!

Below is a dyno chart from the Sierra Sierra Evo, equipped with the EFR 8374, Full-Race Twinscroll Manifold, 2.2L engine, revving to 8500rpm with ~32 lbs (2 bar) of boost.

now if we could only read the numbers.....     pretty fuzzy

[John Hartman]

looks to be over 700lbs/ft and well on its way to 800 horsies.
