[Closed] Borg Warner Efr Series Turbos

[Lithium]

Nice, where did you find the speed info? Shame the car had hg issues, sounds like there was supposed to be a final ace up their sleeve.

[Nee-san]

i thought the speed board did not register speeds over 250kph

hmmm rumours were rife on the day, i was told nitrous was in use too... glad to hear it wasnt.

That claim could end up bring quite good free advertising for Borg Warner and Fullrace

[Nee-san]

It's an RX6 on the Cyber isn't it ?

I wonder how they stack up.

i think i counted 4 efr turbos.... on some sweet machines.

A little birdy told me he counted more than that in the sierra sierra spare parts box.

Always been a killer turbo, search rx6 in SAU and im sure i will have a post or two in there... used them for years.

There was live updates and news on the WTAC site, And my family was helping with the Coote's S13 that Earl Bamber was driving, So I was getting plenty of texts from Sydney.

There have been a few people making aluminum replacements. We've have them for awhile. We left the center with open an 1/8"NPT thread so you can add your preference of barbed nipple. (straight, 90º, 45º, etc) Cool addition. BorgWarner makes one as well, but it is a block off plate vs. replacement.

Yeah there have been some pretty excellent builds using them over the years, but I mean how they stack up against an equally rated EFR turbo ?

[Lithium]

Just to be clear, which RX6 does the Cyber EVO use? For some reason I thought it runs a Power Enterprise RX6R which I believe is a different beast to the Apexi RX6...

[Nee-san]

Apexi, obviously one of the biggest variants.

Friend who was over at the world time attack said that a few BW EFR's went boom during the weekend?

[Lithium]

Any more details? Which cars, EFR models?

Realistically if there isn't any solid info then it could be typical pit area chinese whispers.

[TheKeeper]

We didn't get word of any EFR failures from our contacts, but that doesn't mean it didn't happen.

[Lithium]

Its concerning that 8 months on from the point that they started leaking into the market the confirmed failure versus performance proof ratio of EFR turbos I've found is worse than the likes of XSPower etc. If this murmur of failures from the event proves any truth it'll be more like 50:50. The best results I've seen from them so far make them no more attractive to me than the Forced Performance HTA turbos, and at a higher price.

Its definitely bad enough that there is now no way I'd recommend them to anyone, price aside - unless there is eventually a convincing amount of good results over a period of time.

I hope people start having better luck!

Reasonably sure the tilton evo was running an efr, also spotted a t04z on the advan r34.

[Beer Baron]

hey guys, yeah obviously I can't share everything. we are 'testing' which means stuff happens.

anyway, lithium, neither advan/hi-octane RGM car had EFRs on for the weekend. we desperately wanted one on the R34 but ran out of time. we had a few problems (in fact a series of them!) like hold up in customs, run around with courier company etc and basically just ran out of time to do anything other than pinch a turbo off the R33 and stick it on the R34 (the 33 happened to have a T04Z on it). it was down on power compared to both the twin 2860 -10s and compared to the 9180 we had tested which was a shame but it still performed well. The R32 has been running 2860 -5s and we hadn't intended to run anything different. That car got very little development between last year and this year due to a few reasons mainly because everything was focussed heavily on the R34 development.

The R32 GTR entered by John Bright (BPG car) was running the twin EFR 6258s and ran well. He was only there on Saturday and a had a few small problems with the car (tyre problem, some suspension issues etc). To try and ensure reliability he ran the car with just 18-20psi (as opposed to the 25+ he'll eventually be running) but the car performed amazingly well considering. It's making more power than it did on the -10s and response is as good as the -5s. Please don't take this as gospel (my memory is full of figures right now) but it's currently making over 500hp atw on 20psi. John was put behind due to all the work involved in converting over to the EFR turbos and problems with supply etc (well documented and discussed in this thread) so didn't get to fit any of his aero gear, nor test the car etc so he put in a HUGE effort just to get there on the Saturday and compete. His tuner Phil (Armour Motorsport)and Mick at Corse Automotive also put in many late nights getting these things sorted. We also got some help from Brett Lloyd at GCG. Which was great as our problems had nothing to do with him.

Anyone who saw John's car coming down the straight would not have doubted that is has some good stonk. I took some time out to run down to the exit of Turn 1 and watch him powering out of T1 into T2 and he was very committed and the car looked quick and sounded awesome. It also looked very fast coming out of turn 2 and turn 3 which are slow-ish corner exits.

Once the current issues are sorted these turbos will be fantastic.

The Full Race BOV covers are nice too and not expensive. I'd recommend anyone using any type of EFR turbo get some as they make the turbo's look much nicer and eliminate any chance of snapping off the nipple. I like the one posted before too, looks very cool in bare alloy but I do prefer the design of the Full Race one as it doesn't have the nipple built on, it has a 1/8th thread cut instead so you can fit either a nipple or -AN fitting and means you can fit a 90degree fitting which is handy on the twin set-ups especially.

Anyway, still lots of work to do but things look good so far.

SSE were running their EFR 9180 and to the best of my knowledge they were the fastest car on the straight at something around 280km/h. There's no doubt the potential is there.
