[Closed] Borg Warner Efr Series Turbos

[Beer Baron]

nice info from the tuner. it really does look like a gun set-up.

Yeah good to see someone giving some extra information!

The power at 4000rpm is very impressive

I'm assuming the "old set up" is a stock 2.0L motor with a GT30ish sized turbo

[Rolls]

That is an amazing power curve. Close to full power from 4-8k, thats a 4k spread of useable power!

[Lithium]

That would be one hell of a fast point to point car...

[Legionnaire]

The tuner posts some very nice and detailed info, that's great.

And wow, better power AND response than previous setup, agreed with SimonR32, looks like it was GT30-based. Win-win.

And it loses nothing to factory 4B11.

i want one now.

Even at 18psi it's an animal to make so much power as early as it does.

I wonder how an rb25 would go trying to spool it....

I would expect peak torque to be a little higher in the rev range but the transient area to be a little better to compensate (think linear inline 6 effect).

Now I want to see a 7064 on an SR, might just have to get one LOL

[Lithium]

From this its hard not to consider the possibility that a TS EFR7064 on an RB25 with E85 = GT2835 (probably better) spool/response, T67-25G power....

[Beer Baron]

yeah I wonder how a 7670 would run at 30psi on my Jun RB27? but given how responsive the 9180 was on berrys RB30 I was thinking 8374 for me but if the 7670 can make the power I want (380-400kw atw) then why not use it? I'm still not convinced it's a genuine 600hp/400kw @ 30psi at the treads turbo though but if it is then it's bloody awesome.

[Sub Boy32]

I can't believe how boost thirsty these things are....Hope my engines up to the task

[Lithium]

Beer Baron - Depends on the dyno you're reading at the treads at, some rolling roads (ie, Dynojets) often read the same if not higher than Dynapacks... depending on the setups of course. This is ~470kw @ hubs, I'd say if this is a genuine reading, then I'd think 380-400kw on a DD should be realistic.

Its the EVO that needs that boost to make that power, though I'd still have gone the 9180 for an RB30 personally

My "410kw" on the same hub dyno with the same correction (SAE) went 360rwkw on a Dyno Dynamics roller...

So I would imagine the 30psi E85 run would be around the 400-420rwkw

[Beer Baron]

cheers. so it's in the ball park then.

[Sub Boy32]

LOL! Yeah....We'll see!

I'm not looking for as much power as "The Berry-Mobile"

[Lithium]

Its the width of the compressor map that inspires me to say that more than the outright power numbers - will be interesting to see what kind of power the EFR8374 lets through when not pumping 2+bar through it.

[Nee-san]

Lol 70kw difference between a Hub and roller Dyno ?

Nigga please.

Way to make yourself look like a dickhead

Thanks, but I'm well aware that you've previously posted those results, not really any need for name calling, most of us are adults here.

Maybe on the dynos you use there is a 70kw difference.

I didn't call you a name?

The dynos I "use" is the same dyno with the same correction as the result of the Borg Warner EFR on the last page (so a viable comparison)... It's also the same dyno that STATUS (not from Perth) uses. (battery, with almost an identical set up to mine makes almost exactly the same power as mine on the STATUS dyno as mine does on the Allstar dyno)

It's also worth noting that we know the hub dyno reads higher than a roller, which is why we usually leave correction off. With correction turned off it's still 30kw difference between the hubber and the roller! The 2 runs were also on the same tank of fuel with about 50km of driving between the 2 dynos...

Also in regards to the shot at high reading dynos in Perth, good one... Original, pitty the mph does not lie!

Now you just sound incredibly ignorant.
