[Closed] Borg Warner Efr Series Turbos

[Full-Race Geoff]

here is one of the first 7163 results for the EWG vband housings. its an R35 GTR with 4.1L engine built entirely by SubZero (FR just helped with the turbos). timeslip attached -- watch the launch

[Lithium]

Doh - was hoping for a dyno plot, but watching the vid - damn, that is clearly both making many many kw and coming on very nicely.

Impressive!

[NismoSTune]

EFRs look like great things but fitting long IWG versions to competition cars isn't the same as production ones - particularly if you don't want it to look obviously modified .

This sumbich got to fit 2 IWG efrs!!

^^ what size?

How much power you going for?

What's the rest of the setup? Cams, capacity, comp ratio?

[GTScotT]

Piggaz can sense the aura of MOOAAARRR

Very impressive, looking forward to results. V bands must be nice to work with

[GTScotT]

V band discharge is nothing new, only that these are IWG. They appear to be B1 T2 framed units.

[NismoSTune]

I don't know much other than they are the smallest EFRs and appear flow more on paper than the 8374 if they were truly 1+1 which isn't realistic.

Not sure if the guy frequents this site. PPG helical dog, tomei stroker I know for sure. Tomei poncams but unsure of size.

That should shorten it nicely, and external gate specific, the way I like it.

I wonder if they plan to do split pulse Vband entry... That would be very trick.

Yup!!

Because I would LOVE to fit a 8374 to my car, but unfortunatly the turbo is too bulky...

[discopotato03]

Yeah that appears to be a problem with some of these EFRs . I can see Geoff and a few others thinking we get these TS IWG turbos to the masses and they want to bitch about packaging . I know they tried really hard to make these things work really well but I ah wonder if a bit more compromise with packaging would be a bit more acceptable to the fast road market . Shortening up those long IW T housings has to affect waste gate performance but would a little less still be streets ahead of the turbocharger competition ?

Hard to please everyone I know cheers A .

^ To be honest, I even have troubles with the EWG versions on evos...

Low mount the turbo dump pipe is too restrictive IMO, and top mount looks like ass.... (not to mention changes the weight distribution of road/race car).

[Full-Race Geoff]

tonba -- man up.. its not that hard to fit these in an evo, especially if you take the a/c out

discopotato - more often than not, the location and bracket for the actuator is the difficult piece to fit- not the length of the turbo. Full-Race has a few different WG brackets to suit many different fitments, that is the real key to making these work, knowing where to position the actuator in each application

^ come on Geoff..

These turbos are an engineers wet dream. But unfortunately, I haven't seen any real world results to show how effective they are. Sure, you have posted results, there are sierra sierra, nemo evo and tilton, but no real world stuff.

My car has A/C, its a street car, and it gets f**king hot in Australia so there is no way I'm getting rid of it. (Its not a race car)

I have seen some really restrictive downpipe designs to try and make these turbo fit in low-mount config. Which to me, kills off the gains that could be obtained. Not to mention having to notch engine mounts. Pain in the butt to fit.

I wonder if forward facing is an option? In that case, What I worry about, is running a small radiator..

Ahhhh, Ill find the perfect setup for me one day...

For now, my old FP Black will have to do..

Geoff has a 8374 0.92iwg in his Evo road car.......yeah it gets hot in Aussie, but it's just as hot if not hotter where he lives in Phoenix AZ!

I'm sure he will send you some specs if you ask.

[Tonba]

Thanks mate.

I know and understand he runs that turbo. Been following it for a while. As I stated before, top mount just wouldn't work for me, especially if Im interested in more power (Ie 9180.

It still doesn't get around the fact it is a turbo with awkward and inconvenient packaging. I might just have to stick with a Forced Performance turbo, unless there are future options for different compressor / turbine housings...

You guys with your RB's are lucky, as you have much more room over us Evo owners...

This^^

One thing I haven't found yet is the suggested maximum angle of inclination. It would be much easier to fit if you could angle the sucker on a 45 degree in some situations, but obviously the drain would be compromised. What is the maximum angle you would suggest Geoff? Taking into account the car will be driving up hills also.

I am running my gtx on a 15 degree angle, leaning back in the engine bay to help with packaging on the VQ25det, and it works fine. But there would be a limit...

[Tonba]

^ Geoff would know more then me, but I'm sure I have read 20* somewhere.....

[scotty nm35]

Does that take into account driving up a hill though? 20* plus say a 30* hill = 50 degrees... Bring on ceramic bearings that don't need lubrication, then we could vertically mount them.
