hi guys i installed a boost gauge when started it sits at -6 but when i take it for a run it only boosts upto -2 doesnt even go over the 0 mark what should it be boosting at

its a hdi 110 and my boost gauge works in bars

As far as I remember the HDi runs at 1.0 bar or 14.5 PSi maximum.

Sounds like the air line connections aren't right? I'm sure someone said the ideal place is to tee-into the Denso sensor plug on top of the intercooler as this has positive boost directly from the turbo - check this out first though as you don't want to interrupt the pressure at the sensor.

The 306 forum would probably be more helpful with this sort of thing.

i can try that the now mate no harm in tryin

cheers welly ur some man thats it all sorted now boosting at 1 bar:D whats the max i can boost at i have a manual boost controller

You won't know until you blow up your engine

thats a big help lol think i'll go up a notch or 2

I think it's regulated by yon ecu, altering the duty cycle of the boost control solenoid valve.

You need a remap.....

alot of the 306 HDI users use a elbow from the 406 and thats were they usally tap in the boost guages

FWIW the 306 is a HDi 90 with mechanical boost regulation, 110's are electro-mechanical / ecu controlled.

so a manual boost controller would be no good for a hdi 110 then

Don't know for certain, but I reckon it will see it as a boost control fault, then sulk.

i will let yous know how i get on with it when it gets delivered

This discussion has furthered my distrust of the HDI/ECU control in general and strengthened my resolve to buy, in the future, nothing more sophisticated than a 1.9.


Exceptions made for the V6, natch

A blast in mine would change your mind, Tom. Even my bro - a confirmed veg oil user - is now building a shed in which to brew bio, so he can have mine when it's up for replacement....
