The fuel tank pump is almost brand new, replaced just before you got it. Is the allroad pump bigger?
Sorry for late reply, did go on a long holiday which meant putting projects on the side. Anyway, the solid AKE cams work in BDG/BAU/BDH heads, i have rebuilt 2 allroads so far with messed up hollow cams. If anything, they feel more powerfull as i reckon the solid cams have a tiny bit more lift compared with the hollow cams. Anyway, they drive fine 1 year on since conversion, i still used the cam roller and lifter assembly as they are particular to the heads.Hello,
Aren't you running the custom exhaust fjtwelve had made for the car ? He had already ditched the soot filters if I remember correctly ?
Wow, hold on, I don't think you can install the solid AKE cams in a BDG or BDH head, the profiles are specific for the roller rockers, it won't work. I also did the BDG conversion, runs smoother, quiter, I think the only way to keep those rockers in place
That sounds interesting, 2.0 C.R pistons and 3.0L crank. Which engine is the crank from ? does it need mods ? Which conrods do you plan to use ? What about the piston bowl and injector spray angle ? Much to take into account I would be very interested to know details and discuss the problems and search for solutions here.
I'm going to install water/methanol injection on my AKE shortly

Took Alex, a mate that also has a v6 tdi allroad and he's brother in law has a 535d, he reckons the a6 is faster and puts the power on the road much, much better ! We were swapping turbo's in order to do a back to back comparison: same injectors, same car and different turbo settings and i found the Turbo Dynamics hybrid had a poorly adjusted stop screw, which would explain the poor performance after 120 Mph ! Winding the stop screw a couple of turns back made a lot of difference, however i need to use a EGT/EMP gauge to set it right properly. It's very easy to screw a turbo with a miss-adjusted stop screw !Sounds good let me know when the map is sorted and i'll bring the 535 down and you can do some back to back tests think i know where my money is
We passed 150000 views. Unbelievable.
I have a couple of turbos with bigger compressors and turbines, they are all low mileage, freshly rebuilt ! I have to fit them to the car in order to get the actuator and stop screw set-up properly as there is no factory setting for hybrids ! Larger nozzles and a 3bar map sensor a good remap should see you close to 250-270Bhp ! That's a lot of fun in a car over 1500Kg !
Had a look at the pump a few days ago and unfortunately it looks like never been changed, most likely it's the original pump that was supplied with the car ! The reason why i think it's the original as there's too much dust on top of it and loads of scratches which will be content with an old item...someone punched the power supply cables with an electric probe at some point in order to check it's working or not.The fuel tank pump is almost brand new, replaced just before you got it. Is the allroad pump bigger?
If 80% is not enough call me to give you +130%.66 compressor on 2.5-2.7 bar will give you 350hp.What more do you want.If you don't like lag put another gtb1749v as a HP turbo.Bosio race nozzles are about 80% bigger than standard, however i still cannot get rid of the smoke under 2000 rpm's on my car ! The biggest hybrid that fits in the stock housing is gt22 turbine and 66mm compressor wheel, however the response suffers a little unless you don't mind a little lag ! With a gt25 turbine housing you can fit a billet compressor wheel up to 70mm in size but we are talking lag in 10's of seconds now !
Hello,
I finally found a few hours to tinker on the A6.
The idle shudder due to the big bosio r683 drove me insane, also moving on and off the throttle when rolling wasn't 'clean'
The problem is the idle stability control that can't cope with the r683's, undershoot,overshoot ... you can see this happening with vagcom under 'engine' measuring blocks 013 and 014.
I made a little metal bracket with adjustment screw that allows me to adjust the gaspedal travel so that it doesn't fall back to 0
% but stays at 1,8% with pedal released. This eliminates the idle control and also the shudder ! Secondly change the adaption value for the idle speed as low as possible with vagcom. Rocksteady and smooth 960rpm idle ! This is a little more than the stock 780 but it is a hell of a lot better than the violent vibrations and the lubrication of the cams was never ideal under 1000rpm.

if want got rid of smoke and idle shudder on the car, the solution was to swap the race 683 nozzles from AKE injectors to AFB injectors and the idle problem is gone
our let`s say you have 50% bigger nozzles ...
to inject same amount down low to avoid flooding the cyls with unwanted diesel you would need to reduce time of injection proccess in order to inject same quantity ... so you must reduce iq by smoke and torque limiter and raise boost accordingly
Thanks for the hints, i believe you answered on ecuconnections as well !Hello,

Idle shudder will continue to exist when you put bosio race683 on AKE holders.They DON'T FIT.THE NOZZLES ARE DIFFERENT.DON'T TRY IT AND THEN COMPLAIN in the forum.
