[Closed] Borg Warner Efr Series Turbos

[Beer Baron]

ahh, d'oh! I thought "thekeeper" was jon! now I'm confused.

anyway, more pics:

[TheKeeper]

No worries mate! I'm Brett, Jon's one of my salesmen (and a good one at that).

[Beer Baron]

well nice to meet you then! I think you know who I am?! I know Jon, Geoff, Raffi and Brock at BW but those are the only guys I've really worked with so far (and they have all been good to work with). You must be too important for the likes of me!

Anyway, those are just a few preliminary pics (taken in my kitchen) but I'll have some good ones later. Someone in this thread already posted some great pics of the 6258 including with the housings off etc so no need to go nuts. but I don't think anyone has really seen the manifolds for the RB26 tiwn 6258 kit up close and not fitted to the car before.

Ha ha! Nah...I'm like the crazy uncle you keep away from the rest of the world.

I just usually stay behind the scenes on most transactions, but I've been involved with a lot of the BW testing and talk with BrockStar regularly, I've been particularly impressed with the twin 62/58's thus far. (mainly because we really haven't had many of the big framed turbos) We don't have that many RB's here in the states and the twin set up we've tested out here has been very promising. (Very linear, plenty of power down low, no shuffling, quick shift recovery, etc)

What size injectors and how much fuel pump do you have going to these things? And what kind of fuel?

I have.

Nice Pics! Photos look sharp!

If I was in the States I would have got a Full-Race Manifold to go with the EFR 8374 I have coming....But it does get up there when you add the postage and Duty and GST into NZ

[Lithium]

Very very nice - so to clarify, there will be dyno results for an EFR9180 and a twin EFR6258 setup coming soon?? Are the setups ones which the potential of these turbos might be unleashed?

Either way, and fingers crossed for some good numbers

[Trozzle]

That is some seriously sexy welding on those manifolds....my god

well I probably personally own more GTRs than there are in the whole US!

feel free to send me the 8374 kit to try!!!

You know about the 9180 car I think? it's a 3L, plenty of fuel, plenty of supporting gear and running on E85. No effort spared on that car. Boost will be as much as the turbo will efficiently run. Probably around 30psi or so? unless it makes masses and masses of power in which case it'll be turned down a bit (would have to be a fair bit for that to happen though!).

the twin 6258 car is running E85 too, again plenty of flow in both injector and pump has so far made over 400kw on 2860 -5s and a bit more on the -10s with the current support systems. It has a tough 2.6L and all the supporting gear and we are hoping for 450kw or so out of the 6258s and prepared to work them hard to get it. Comparing both compressor maps and just the basic wheel specs between the 6258s and the -5s and -10s tell me the 6258s should flow as much as -10s, they will be efficient at higher boost levels than either the -5s or -10s and much less prone to surge than the -10s (due to matter size match of compressor and turbine wheel). so basically -10 power without the massive surge zone. so much nicer mid and low range and still a bit hit up top.

yep. due to help from BW and Full race with the 9180 etc we'll be giving them feedback on it's performance and I'm sure they will most likely want some of the stuff like dyno sheets to go public. though being a competition car we don't want to give too much away but I'm sure dyno sheets will be forthcoming. Same goes with the 6258 car and yes results for both will be coming fairly soon. like count the time in days or weeks. certainly won't be months as they both have deadlines.

and yep, both set-ups are ones which will allow the potential of the turbos to be unleashed. they are both full on track cars so goal is driveable, usable power and lots of it through as wide a band as possible.

fingers crossed they both make good numbers indeed! I pushed hard for EFR turbos on both these cars so if they don't work I will have to relocate to arizona and move in at full race as my house will probably get burnt down or they'll make me eat the 9180!

That would be the High Octane R34 Time Attack Car?

[R31Nismoid]

You would be correct

[Sub Boy32]

Did hear a while back they were looking at the 8374 or the 9180.

I do wonder if the 9180 will be too big for a Time Attack car.....But then again, Eastern Creek is a big track, I just hope they have some Aero/Downforce for that monster this year.

[R31Nismoid]

There is certainly just a little bit of aero going on from what i saw last week

Some really impressive/detailed stuff, along with the rest of the car which really does leave you jaw on the ground.

After just seeing that one car, I'm spewing im working and can't make it to WTAC

[Sub Boy32]

I should get my A into G and book a flight to watch this year....Fly there, take train to the track, watch some WTAC, train back to the airport, fly home.

I love Sydney public transport....probably cheaper for me to fly to Sydney to see this, than flying to Hamilton for the V8SC's......And I live in NZ!!

[N1GTR]

I love Sydney public transport....

Lol

You'd be about the only one that does!

[Sub Boy32]

...Compared to NZ's, At least Sydney's transport goes to somewhere...

I do know about the 9180 car, that's a bad ass. I expect to see BIG usable numbers out of that thing.

The 6258 car may surprise you. We saw 405kw at 19psi here on our crappy 91octane fuel. If you're going to turn the boost up and run E85 and really "work" those turbos I wouldn't be surprised if you see closer to 500-520kw. Depending on boost levels obviously and provided you have enough pump/injector. The 6258 car here in the states ran out of pump, but had 2000cc injectors. It's running the ProEfi with a flex fuel sensor, and once there is more pump installed he'll hit the dyno again with E85 and see what she'll do. (and when it's not 110º outside)

[CaBS]

and yes results for both will be coming fairly soon. like count the time in days or weeks. certainly won't be months as they both have deadlines.

Very keen to see how this goes!

Hopefully someone does some 7064-IG-TS+SR20 as well so I dont have to be a test pilot incase they're a flop on these engines!

[Sub Boy32]

As soon as my 8374 arrives and I have got Sinco to make the manifold (They have tacked it together to check first that it fits with this turbo) I will have the car on the NZEFI dyno (4x4 hub dyno) and we will see what it's like on a built RB30/26, I will post results/dyno sheet when done

Lol

You'd be about the only one that does!

Whys that?

I use a multi 2 ticket that gets me on any bus, any ferry, any tram and any train within the metro area with unlimited use for the week.

Trains are seldom late, buses fill the gaps, ferries make for something to do on the weekend, so on and so forth. I should get my license back in 2019 and so far the last 3+ years without it havent been bad

Ill be right back, the sarcasm alarm just blew up and needs to be replaced
