300tdi torque and bhp figures?
Porny:
Tim boost gauges…
I've used the 2 bar ones in the past, not that bad (plus I can get them trade)... I've had some that were spot on in accuracy... and others that were miles off!
I actually spoke to the importers and they have no way of checking them!!
Autometer ones aren't bad (I think I can get them trade too!), but for quality the VDO ones are very nice!!! (but not cheap)
At the moment I just use industrial ones (from a local pneumatics dealer) - cheaper and accurate - but no back light and not that well damped. But mine are not permanently installed, I just connect them up when I want – have a nice little aluminium mounting :wink:
I’ve also been playing around with decent regulators/bleed valve…
IMHO easier to play with the boost with one of these, rather than shortening the actuator (especially on a 300Tdi!!!).
The one I’m using at the moment is a nice bit of kit, and is spot on – no peaks etc etc. Was running round at 17/18psi which goes quite well, but I need to adjust the fuelling to suit.
Have also played with stopping waste gate creep (i.e. stopping the actuator moving until it sees 14psi – as standard, an actuator will start to move, thus opening the waste gate before this, so boost takes longer to build up to the pre set level) – in all honesty doesn’t make that much difference on a 300Tdi – is slightly better, but not a huge amount.
You can also allow it to temporary overboost….
A 1 bar gauge is not really enough, even as standard you will find most 300Tdi will overboost slightly (usually about 1.1bar)… really you need 1.5bar or 2 bar.

Yup i've found out a 1 bar isnt enough!!!
I may just jump in and buy a VDO gauge..... At least they will blend in more. I dont really like the silver bezel on teh autometer ones, although they look good. Hmmmmmm...... decisions.....
Dont spose you can get the VDO's trade can you?
One of my mates has a dump valve fitted on his 200, i am of the belief this does nothing except change from the usual clatter clatter clatter clatter to clatter clatter whoosh clatter clatter whosh... Am i correct?

GAAA teh vdo goes up to three bar!!! not required....

That was 'my' exact description posted in another thread!!!.... :wink:
On a petrol yes, on a diesel no point IMHO.
Looking (again) at VDO one, looks the nicest, but not very well laid out, more a quide than an accurate measurement.
The nomad one ones are quite nice:

No sure what I can get trade at moment... I know I can't get VDO ones...
But as you say 3 bar is a bit much..
Is a shame that nobody does a diesel specific one - as you do not need the minus numbers - you will never see a vacuum on a diesel!!!
