[Closed] Borg Warner Efr Series Turbos

[Full-Race Geoff]

dont know if anyone can confirm this. But i have been told by a large Aus supplier that BW may be dropping the whole EFR range due to 'internal problems" in that side of the business. apparently they have spent so much money on R&D , marketing etc and has cost BW lots of money. and the big bosses at BW may scap the whole thing.

100% incorrect - in fact all of the indy cars next year will need to run (2) EFR 6758 T25 turbo or (1) EFR 9180 Twinscroll T4 turbo. BorgWarner's EFR turbos are the real deal, its just had a way too small supply and a very high demand

I heard that they were having trouble with there suppliers manufacturing quality control and have had to find a new supplier. If this is correct, that would take a fair while.

correct

I'm very interested to see if teams lean towards the twins or the singles. It will add lots of fuel in the twins vs single debate.

I think it will come down to engine configuration as to the deciding factor for packaging.

[zebra]

they all run the Cosworth v8, (or is that Champ car?) and the same chassis, so will depend on where the engineers want the weight in the car.

I would imagine most would go twins then, unless they mount the turbo at the front/back of the motor. Be interesting to see the layout.

[zebra]

Yeah they all run big singles behind the engine above the gearbox. I can see most stating that way as they are already t4 twin scroll Garrett's iirc

Pretty sure they have merged now bro IRL and Champ Car

Anyone got theirs yet....?

7064?

7670?

8374?

9180?

....Perhaps I should have ordered the twins

[Lithium]

I admire your patience, to be honest! Almost a year has gone by

[Super_Dude]

I've got my 1.05 twin scroll 8374. To bad my car is currently on the back burner right now without an engine.

Another EFR faluire on EvolutionM forum. Im feeling sorry for the guys that've been waiting for over a year for there turbo to have this in the back of there mind - When i actually get my turbo will it fail.

I can say the car is stinking fast. First two sessions of the shake down run were great. Went out for the third session, hit the back straight and see a m3 passing me while at WOT. I'm thinking wait how is that even possible (Nobody could even come close to my backstraight speed.)Look down.... 0 boost and a supercharger like whine. Limped it in to see if it was any easy fix.

Luckliy I had the guys from RRE down doing track support so they checked and found no boost leaks and from the intake side it looks like the wheel started digging in to the inside of the housing. It SO hard to see. Running the car, There is a heavy metalic like whine, and with the intake off and putting your hand over the intake side it definently sucks... no leaks everything bulges like it should. The one interesting thing is that when you stop the car... the wheel just stops instantly... typically I was told on a BB turbo the wheel keeps spining.. this just comes to an abrudt stop.

So the car is headed back down to RRE for the turbo to be removed and inspected... But if it was damaged from the original issue, I'm wondering if that may have been part less then stellar results? I don't really know... but I'm trying my hardest to get a solution together before Tuesday.

So, the turbo is off and as far as RRE can tell the bearings are fine. The turbo does not spin because the shaft is bent. That is making it bind on the bearings. One sise of the compressor wheel has relatively undamaged blades. They do not contact the housing. On the opposite side of the wheel the blades are all ground away. We are pretty sure that it wasn't caused by the prior motor’s death.

just when i wonder what ever happened to my efr quote.... you come back to remind me

[Lithium]

Pretty pleased I didn't get caught in the moment and order one like I felt mighty close to doing back in around Feb, I really really like the idea of them but regardless of how hard BW have tried and how good the intent is - this isn't good from a consumer point of view.

Absolutely nothing against Full-Race, or Borg Warner... seems like this is a nightmare for all involved but again from the point of view of smart buying there is no way in hell I'd recommend anyone an EFR now, the delays and reliability are well and truly below what I'd call acceptable - especially when talking something this expensive that has still yet to give results that separate themselves from anything else on the market.

It's been an unfortunate series of events to be sure. Had BorgWarner known they were going to run into the production woes from their vendors they certainly would not have launched the product. Fact is, most turbos are holding up just fine. They have determined the culprit of those that have failed and all have derived from one vendor, and the problem only arose AFTER they were mass producing them. We have several that are in use now, taking plenty of abuse and no signs of failure on the horizon. I can say that the turbos we are getting now are solid, but very sparse. It will be another 7-8 months before these turbos are sitting on my shelf, in inventory, waiting for new orders. We see a lot of upside to these turbos, A LOT. It's just been overshadowed by production speed bump after speed bump.

Its interesting to me they seem to be bending shafts, is this related to the lightweight shaft materials or just bearing issues they needed to sort out?

Bit of a shame really, finally a company trying to supply us modern turbos, with space age materials, and its let down by quality issues. I hope they sorted it this time.

....Just make sure mine doesn't come from that vendor, haha

They way I see it, turbo manufactures are pushing the boundaries to reduce lag and increase power, You are always going to have a few hicups with new development.....This hasn't helped BW as it's one the back of the huge delays due to a vendor not able to produce parts to BW specs....

....But I'm sure when they find all faults (Which no doubt they will have by now) they will be THE turbo to have

The term "space age materials" does make me laugh a little
