Those with boost gauges
Hi all I am just wondering what others see on their gauges, I cannot quite understand why at 3k revs on the overun I get a boost reading of 3 to 3.5 psi, no fuel is going in so at a loss to explain it, Rick

I think i know what you mean Rick, I haven't got a boost gauge though! The engine will still be taking charged air in without fuel which will spin the turbo which will charge the air I THINK What is the usual boost pressure and where have you connected the sensor?, and like Blocky mentioned, blocked egr might play a part!

Nothing, I am starting to think along the lines of traffic pollution, but will take some convincing, Rick

Try facing your snorkel intake backwards see if it makes a difference, thats what I do with mine with no negative effect, and it sounds lovely with the window down a bit
If you have an intercooler connect boost gauge to the "cool" side of it for a more accurate reading, or even further! |

Snorkel is backward facing and sadly do not have an inter-cooler, might tap Zac up if he has a spare with manifold, Rick

Just an update on this one, been suffering some performance issues of late so stuck the same gauge on today and only got 8 psi max, now I cheated a bit as did not put a tee in to enable connection to the fuel pump compensation, (could not find a tee) but will sort this tomorrow and see if makes any difference but I have not noticed any performance loss due to this being disconnected so am wondering if my deep wading a while ago has let water into the pump mechanics causing problems, Rick

OK put a tee in the line so now have pump fuel boost as well and got just over 9 psi at around 3k revs, so pump boost certainly working, but will try adjustments to see what difference they make, Rick
