Any body been using these recently?

Heard a few people say they are out performing Garretts GT range.

What are peoples opinions on them?

Pardeep

A mate of mine is contemplating a K26 for his MK2 Focus RS

I got told that the BWs where still out performing even the GTX range. This was from a well known Evo Tuner who had a beetle in of all things running one

Just interesting to see if naybody else had used/tried something and has graphs to show results compared to a garrett of a similar size/frame

-beefy-

iTrader: (6)

it always puzzles me why almost all cossies seem to run garrett only turbos ,


espically considering the vast range out there from other manufacturers ????



sweeds and norweigans will fit anything !!!!!

I'm sure Rod has used one, Ricky Lee has also dabbled with them I believe

Plenty of people get great results using them

Im in the middle of reading on MLR about them. Not really got to any cold hard results/comparisons yet though.

A quick looksie at a the Sierra Sierra Time Attack car (which is fitted with a 2.2L Cosworth motor) http://www.sierrasierra.com/car

First the EFR8374

220hp at 4000rpm
Whammo 717hp by 5000rpm.
Similar torque figures



And then the EFR9180



Blatant copy and paste from MLR

bigchez

It is running 43.5 psi though dude!

Ive used a s400sx good for 750bhp, in fact if you want one its in the for sale section with only 150miles on the clock it has ETT technology.
The latest range of BW turbos are steps ahead of anything Garrett have on offer. I use the latest Garrett gtx as it puffs the power, if rather sluggishly, but it will be replaced by the latest BW.
The Borg will be the very first twin scroll turbo on general sale, all Garrett turbos are an existing design made to work as twin scroll. Its not a direct replacement for a garrett, its longer. It has ceramic ball bearings & a speed sensor.

I sold i fiesta 1.25 engine on ebay. tried to cheat the fee and it sold for Ł1.20 When the guy came to pick it up he was gobsmacked i let him have it. In my eyes, if your gunna play the game your've got to be prepared to get bitten in the arse every now and then.

Thank you.

Mike, whats that got to do with BW turbos?

Rod, which model turbo you going for?

Im really eager to see how these perform and what the cost is like as ill be looking for a 350-450hp turbo later this year as I think my curent ebay effort will be a bit of a time bomb very soon.

HockeyNomad

I thin k most ford owners Garret Turbo's as that what they came with out the factory, so we just bolt on a bigger one that fits the flanges, cheap and cheerful, as we dont have to change/redesign manifolds they are just off the shelf etc,

also we get used to the naming structure of garrets, but when you look at other turbo manufacturers with their completely different naming structure it makes it trickier to figure out what kind your looking for,

but im definately interested in learning more about the borg warner turbo's

i have a bw turbo in my garage that i'am machining a garret turbine for
it has a real nice turbine and has extended tips on the comp wheel [exducer side]
ment to give more boost with out the lag

i'am running a holset with a .63 turbine from a garret

look at the back it has a 5 bolt ford housing
this is pic is me having a fit up to check blocks not finished yet

timrud

What about Precision Turbos?

Rod-Tarry

I leave all that to Mark but their will be a turbo for all conversions. Hes discussing things with them at the mo. If it does what they say it is a break through no doubt about that. Problem is Its like computers/tv's you buy the best now & a year down the line its a heap of dung cos things have moved on.

stevieturbo

Most of the BW stuff has been in use, producing great results, especially for the money for a good 2-3 years in the US.

Just seems slow on the uptake over here

-beefy-

iTrader: (6)

so does anyone know the eqivilent turbos to say a gt3071/76 fromt the other manufacturers ??


ie , turbonetics , bw , switchzer , kkk , ???

wozzy

not the new EFR range, completely different kettle of fish

the borg warner EFR equivilent to a 3071 would be the 6758 and the equivilent to the 3076 would be the 7064.

( the above garretts not being the GTX range )

Rod-Tarry

The EFR range was launched at the end of November 2010 at Sema. Mark went over to have a chat & get details. Its a turbo designed from scratch, not an improvement on last years model.

Acidburn

Interesting to read about, thanks for letting me know to have a look.

Out of interest whats the equivilent for the gtx ranges (3071/76)

or is there one that would be recommended for 500bhp?

Fiesta_Jed

Last I heard there were reliability problem during testing of the EFR range Something to do with the materials they were using, this is why they have been slow to take over here.

The air werks range are pretty good though.

Holset turbos are very good aswell.

pee vee

fukkin hell mate... if the car i drove is anythin to go by,
there is quite a lot wrong with a T66 it was horiffic

might of been a bad example though lol

Mark Shead

Theres been a couple of problems but I think thats a thing of the past,
I have one in at the moment to test on a Evo,
I have been running the air werks stuff now for a while and they have been awesome.

Mark

Acidburn

Hi mark

do you sell them or do you have a place you'd recommend to purchase one from?

cheers

Mark Shead

Yes.

This is a EFR on a Evo.

Mark you got the one for the turbo that was on previously. Been following this on MLR and would like to see a direct comparison.

Mark Shead

This is a BW S200SX and a GT3076 on the same car.

Mark

Mine will be running the S300SX, it's a true twin scroll turbo, not adapted to run twin scroll like the Garretts. Will be interesting to see how it performs, has EFR technology built into the latest 300's

TimC

iTrader: (1)

The torque is incredible. This is going to be a popular turbo

wozzy

GTX3071 - 56lb/min turbo EFR 7064 - 56lb/min turbo

GTX3076 - 64lb/min turbo EFR 7670 - 64lb/min turbo

Judging by Marks recent test though, I'd pick the EFR over a GTX

Rod-Tarry

After Mark saw that graph & how soon it spooled he rang me & convinced me its what mine needs. Will be using the biggest they do think Mark said its used in Nascar racers or some such race series. Anyone want a GTX4202 .

Chip

iTrader: (3)

Nice to hear that the initial reliability problems have been solved by the sounds of it then Mark.
They certainly seem to perform well.
That graph is incredible if the only difference was the turbo.

Would be nice to see a GTX3071 on the same engine too though as thats a more relevent comparison really than the now out of date by comparison GT3076.

Mark Shead

Not the same engine but the green line is a GTX3071 on single scroll the blue line is a twin scroll GT3076 and red line is the BW S200SX,



And if you overlay the EFR on the same engine.

Mark

TommyB

The BW turbo seems to be the choice for most big power Honda in the US,

thebronze

NO TURBOS IN NASCAR......... All power is N A

Mark Shead

He meant Indy car as they are running on the single turbo cars a BW9180.
