Title: Just turned the boost up.
Post by: simon15 on July 21, 2007, 12:25:00: Well been meaning to do it for a while and done it finally this morn. only took about 20 mins and its really straight forward.

it should be running approx 16 psi now with fuel to match. Had to adjust the smoke a couple of times but only got a small amount now. :)

It makes such a difference with everyday driving it actually goes up hills without moaning now.

Post by: davidlandy on July 21, 2007, 13:51:46: dont turn it up too far else it may go pop

saw someone do this, admittedly a bit more than 16psi - at first he had a grin from ear 2 ear , within a few days it was tears.

oil everywhere - engine kapput

:shock: :shock: :shock: :shock: :shock: :shock: :shock: :shock:

Wish I'd done it when I bought the thing it's like a different car..

starts better ticks over smoother and pulls like a train when you want it to 8) 8)

5mm, four clicks, 90 degrees = woosh 8) just followed the step by step on steves site ,well done that man If we ever meet theres a pint in for ya.. :D

Post by: simon15 on July 22, 2007, 21:13:12: had a look at dadss 300 yesterday afternoon after loving mine and the actuator is behind the manifold so not easy to get to at all...

and that was the hardest part i found putting the rod back onto the actuator after shortening it...

Post by: Range Rover Blues on July 22, 2007, 21:17:40: What did you tweak the boost to on the 300 then?

Post by: simon15 on July 22, 2007, 21:30:19: i never touched the 300. too fiddly to get to...

might look into it as it makes sooooooo much difference.

Post by: Sharpshooter on July 22, 2007, 21:49:35: Well. I bought an Allisport full width intercooler at billing yesterday. I fitted it in haste last night and was well pleased. I adjusted the boost preasure and the diaphragm, as per their instructions. I droveit this morning, and WOW.

But tonight, i have cleaned and waxed her, so i though i would see if i could improve it.

I actually backed the boost off a very small amount, and it hasimproved it.

So now i have a disco pulls like a train,and looks the danglies.

Smiles all round.

And yes, it was worth the money. :) :) :)

Post by: Ja1983 on July 23, 2007, 19:42:13: take it Bleed valves are out of favour again?!

...dawes device?

may be an easier alternative on the 300TDi if the turbo is too tucked away 8)

Post by: lee celtic on August 30, 2007, 23:44:10: hi all

for the last few months I have had a pish pish pish noise coming from the back of the engine in the car .

I have changed the exhaust gasket ,and the fuel return lines and tightened the injectors . after tweeking the fuel pump and turbo I went to mid wales and going up the big hill (and if you go north to south you will know the big hill it got louder and yes the head gasket went but not badly
It missed oil and water ways .

I stripped it and had it checked at work down to 2 thou and it was still flat :shock:

rebuild with new stretch bolts and gaskets total Â£63 result :D

It was defo blowing before tweeking so no complaints .
just thought I'd say now having done a head it was easypeasy and if you follow the torque maps that come with the gasket it's not hard so I am still happy with the tweek but now knowing how to do the head I want more umph any ideas??? :twisted: :twisted: :twisted:

Well that one whent way over my head. What's a bleed valve then?

A slightly bodge method of increasing boost pressure...
A bleed valve, does as its name suggests... and bleeds air from before the turbo actuator - thus fooling it into thinking the turbo is supplying less boost pressure than it actually is.

Some bleed valves work quite well.... others don't.

I've had success with valves from my local pneumatic supplier in the past.. and cheaper than most other places.

Post by: Ja1983 on August 31, 2007, 10:01:05: sorry, just woke up!

the trouble with bleed valves is they can produce "spiking" where boost sharply jolts up and down as oil/gloop breifly bung up the aperture on the bottom of the valve.. (worse if a 3 way - one with a drain - fittted)

the dawes device is an evolution from the bleed valve using witchcraft and springs (google DAWES DEVICE)

the advantage is that the valve can be fitted in cab, allowing "on flight adjustment" however, fueling is NOT controlled by a bleed valve, so results can be iffy.... probably best spending an afternoon setting it up properly...

Whats the effect of fuel with the 200TDi tweaks?
