I know next year when I get my Mk5 TFSI I will be running on of the EFR range turbos and aim for 500-600bhp... :driver:
As far as I know this is the first 1.8T BAM LCR in the UK to be running this setup.
The new Borg Warner EFR 6758 Turbo 275-450bhp
http://www.full-race.com/store/turbos/borgwarner-efr/borgwarner-efr-6758-turbo.html
Not a cheap turbo but a fecking AWESOME turbo. Its the first big turbo I have tuned which can spool near enough on par with the k04-023 by having peak torque below 4000rpm and go on to produce 420bhp close on to 8000rpm. If tuned with spike it would go on to produce 500lbft with ease by 4200rpm. :drool: but would make the car a nightmare to control/drive.
We opted to peak the boost at 22psi at 4000rpm, then ramp the boost linear to 26-27psi by 8000rpm to maintain a flat torque band. The turbo would boost at 32psi happy and all day long and could make 480-490bhp maxed ou. :grin:
This it the way forward imo.... We all just need to win the lottery.. :grin:
The graph below is of one of the runs from our live mapping session this morning, layed back to back with a stock AMK 210bhp k04 graph..

If you dont understand dyno graphs then the picture below will put it another way.
Ben is the stock K04 turbo and Lee is the new Borg Warner 6758 turbo..... :rolleyes:

The car is also running WMI for cooling and has 100bhp shot of NOS to hand to squeeze the peak power to around 500bhp. :evil:
Anyone with a mk5 TFSI wanting to run this turbo??
-
Yes! ^^^^^ Would love it... always thought about WMI & NOS together! It works then?
-
My mate has a 500hp 1.8T (bored to 2.0l)... no meth. It's a pig to drive, but genuinely hilarious.

I got lot of 1.8T running NOS and WMI combi and they run spot on. Never tuned a TFSI with them both.... yet

This is easy to drive with the linear throttle and boost mapping... Bit of an arse twitcher in 4th gear at 600rpm

Is that the black one Mike,that was at the psi r/r meet few years ago!!
-
Yeah, Wilko's more door sh*tter.
His is as linear as you can get it, has a very trick valve train & headwork and revs to near as damn it 9000rpm when in full-attack mode - but there's no getting around the fact it's a massive blower :signLOL:

And still the same 1/4 mile time as my home made k03 -001-023 hybrid as GTi inters last year. :smiley: He won fastesr in 2wd VW class on Saturday and on Sunday I won fastest in class with the same time.
-
Yep. As I said, it's a pig to drive - even with a diff and sticky tyres, it's useless until you hit 3rd, especially on the Inters surface. On the road though, it's frightening when wound up.
Wasn't it damp/wet on Saturday? I wasn't there. I drove it on Inters 1/4 in '10 when it had 400hp and managed a 13.4 (link (http://www.theresults.co.uk/theresults/Results/2010/Motorsport/GTIInternational_0627_qtrm.pdf)).. still sh*t for its power :grin:
What power was your car running last year, out of interest?? I thought Chris ran a 13.1 on Sunday, taking the MK4 prize??
EDIT - I found last year's thread. RTEC Nick " was running 257bhp 280lbft in 1st, 2nd and upto 3800rpm with just the turbo and water injection then in after 3800rpm in 3rd I hit the NOS button to give me 346bhp to 7900rpm". God bless my excellent memory.
I ran 13.7 in a 300hp 135i, which probably has 150-200 kgs on yours.
-
Looking forward to some new turbo options :popcornsoda:
-
Always good to see new options for getting proper power :laugh: especially as its something im going to look into doing over the winter!
Does anyone know whats happening with the bsh woa manifold as i read the other day that its not being produced anymore?

Your build thread gonna see a major update soon then :grin:
-
Theres a round of mods at AKS 1st.
Don't need any more power but if it can be had and retain driveability then :evilgrin:
What winds me up is 'needing' a new intake for certain software setups it was insisted for Giac maps and pute off.
In tank pump, plasma coils I'm willing to do, rs4 injectors if the spray pattern etc is right and I'm not just going to cover my tailgate in soot
You do it first lol
:driver:
-
is there enough room for the EFRs on the 2.0TFSI? There isnt on the TTRS

There was no room on the 1.8T LCR..lol

By looking at it I am sure it would squeeze in to a mk5 2.0Tfsi, well I hope so.

BSH don't do them anymore, the Manifold are now a part of the revo range of hardware, so get in touch with them :wink:

The mani is made by a company called AFI turbos. They make some very tasty manifolds for many makes of car. As Jake says, the mani is available through the Revo dealer network.

Im sure James will be interested in this once he gets a new engine to play with :grin:

He will be getting a CDL by the sounds of it... I would be nice to get one to fit in there

How much is this turbo then?

$1800 and like rocking horse poop at the moment

LCR with EFR6758 and a LC (4WD) with EFR8374 (not up and running yet).. :happy2:
-
Staplers had the car with the LO4XX on at the weekend.
They had to turn it down evidently it needs some half decent head bolts and a proper head gasket.........
It is going to be fantastic, needs a new pump which is 90% done
So expect a whole new avenue of 400+ Ko4 cars that can be installed in a day.
The loba turbos are heavily modded not just the turbo itself but the mani gets a lot of attention, they look the part apparently
-
With all this power my main concern will be traction

A new intank pump? Stve alread had a variant of upgraded in tank pump
-
I'm assuming they will be fitting LOBA fuelling system ie HPFP and injectors.
-
wonder if loba could do a TSI version with stock dv location just like apr k04 kit
-
just got back from holiday, i would be up for giving this turbo a blast, would be easy to install as the engine would be out :driver:
nick give me a call :happy2:
-
The main problem with this EFR turbo is availability and longevity. Originally there were issues with it falling apart. Dont know if thats been fully resolved which is why the availability is so poor.
The LO4XX looks like it may be the easiest way forward.

There ought to be a vRS / Dyno / track test mule...... :evilgrin:
-
There maybe a Polo GTI 2.0 DSG L04XX test mule soon. :driver:

Stevies car was only running around 1.2bar. Apparently they are capable of handling 2.0bar with ease. Even with 1.2bar he was spinning the sh*t out of the front wheels. He said to me that the map needs to be tailored so that it doesnt come fully on boost in 1st and 2nd gears to get the car going then liven up after that. That turbo is easily capable of 450hp
-
That was the target figure but with good manners, thing is that's why they're calling it the 4xx.
I've been working with LOBA for a bit now and they are diagonally opposed tothe usual tuning house bullsh*t.. mega reserved and let the products do the talking, they don't do software in essence they're manufacturing bullets for others to shoot
It certainly looks the part, the impeller leading edge looks exactly the same as the front fan of my Jets engine. By definition the tip,of the impeller is travelling faster than the root, so Loba machine the leading edge with a reducing angle of attack to get the max out of it. Half span kink energises flow.
This really is cutting edge tech for turbos, it's a definite step forward from the franken-turbo hybrids we've had in the past and is more to do with the capability of 5 axis CNC machines...wouldn't want to be sat with a shed load of stage 3 / 4 turbo kits on a shelf
