Boost - sherman306 - 11-11-2013
Right finally lashed up a boost guage today and been driving it about and it's boosting to 16-17 psi and it's not tuned at all still got the tamper proof caps so I know it's not been played with is this normal?
RE: Boost - underground375 - 11-11-2013
Hmm mine ran at 12psi standard, some are known to run 14. I reckon something's been done on the turbo side.

Hmm but there is a slight haze on boost so it's not too much for the fueling
RE: Boost - underground375 - 11-11-2013

Lda is what controls adds more Fuel when boost kicks in (on a Bosch pump) what pump you running?

Lucas man no Bosch as yet
RE: Boost - Mitch - 11-11-2013
Mine was 13 as standard, a friends was 15, so hard to say really, 16-17 is a bit higher so may of possibly been messed with
RE: Boost - Tom - 11-11-2013
Somebody's played with it by the sounds of it. Shouldn't haze on boost if it was standard.

Not much you can only really see it at night in headlights but the tamper proof caps are intact mate?
RE: Boost - 306pc - 11-11-2013
You'll see a lot more with lights through it at night. Open turbo fully and max fuel till a little smokey, close boost compensator all the way. Did this when I had a Lucas and it went nicely. If you leave boost compensator or wind out it will smoke like a truck.
Jammapic has a great thread on tdoc.co.uk
RE: Boost - mr_fish - 12-11-2013
IIRC your on a K14? the turbo actuator could be seized. That what happened on my old engine so it was around 18psi when driving....as so as more fuel was fed in it was up to 26psi without touching the turbo.
Boost - sherman306 - 12-11-2013
Ah right I'll have to have a look when I tune it can they be unseized?
RE: Boost - willJspears - 12-11-2013
have you done any other mods to it i.e exhaust, i havnt touched my pump yet and im running 15 psi just with a straight through exhaust
Boost - sherman306 - 12-11-2013
I've Decatted it and disabled the egr
RE: Boost - Danny Wideboy - 12-11-2013
If it's the black plug on the front you mean,its not a tamper proof seal that remains intact to say it hasn't been opened/messed with,its supposed to be a one way screw that you cant undo so if it has been undone gently without marking the plastic you wouldn't really be able to tell if its been turned up.
Best bet is to just turn it up,that way you know its been messed with.

The decat will let the exhaust breathe better and could up boost pressure slightly
Boost - sherman306 - 12-11-2013
I ment the small cap on the boost compensator screw
RE: Boost - Tom - 12-11-2013
Well in that case someone could of easily opened the pump and gave it some more max fuel
Boost - sherman306 - 13-11-2013
On the way to work it was boosting 16 psi and holding it nicely so I'm guna tune the pump abit and see what the outcome is
RE: Boost - Jimbo - 13-11-2013
22psi should be safe enough on a lucas anymore you might aswell go bosch
Boost - sherman306 - 13-11-2013
Shame my cheaply boost gauge only goes to 20 psi
RE: Boost - Tom - 13-11-2013
20?! How do you live, im getting a 40/50 one!
Boost - sherman306 - 13-11-2013
Because it's standard at the mo so when more boost is to be had so Will a better boost gauge
Boost - sherman306 - 16-11-2013
Turned the pump up abit today still not really seeing much on boost smoke and boost gone up to 20 psi lol
