Turbo and EGR system issues/compatibility

[Barry123]

Just in random thinkmode, haven't bothered to sit down and figure it out properly yet...

Are there issues when it comes to turbo'ing say, the J4, and the EGR system?

Do saxo nerds tend to whip it off into the nearest bin when turbo'ing?

Most people bin the EGR even in mild state of tune ladyboy.

The old method people used to do was glue a coin over the hole left in the head :D

by mild, do you mean, non-turbo'd and just an induction kit or something? Never understood why tbh :wacko:

i binned mine ages ago as its pointless and just adds weight lol

[blackie_2k5]

yeah majority bin it even with no mods

make it happen

It improves the economy though o' scruffy one. It's probably why I get 45 mpg whilst everyone gets about 5 or whatever, thinking about it :cool:

So not one turbo or n/a build has the egr??? Is it laziness? pain in the ass to map?

Alright I'll rephrase... can I keep the egr? is it still effective? Or is my car doomed for shite mpg off boost now?

arrgghhhh

[blackie_2k5]

the egr only saves you amounts of fuel when the car is cold..the map runs a little richer in warm up mode..and emissions are slightly higher..if it warms up quicker the car comes out of warm up mode and job is done

the car will warm up quicker with a turbo ;)

so if its mapped well youll probs get better mpg off boost..mines mint on juice if im tame with the right foot..


edit-
well mostly anyway :homme:

its does still work all the time..but not in any rate worth worrying about..its more for emissions POV then for better mpg..

A lot of high spec builds are obviously built for power not economy lol, and as the egr valve has no use for giving out extra power it's just binned off and forgot about

I don't see any reason why it couldn't be re-fitted again on a high spec build if you really wanted to fit if again, but there's no point really as big builds generally give shit mpg

Edit: beaten to it by a better explanation above

If someone doesnt mind telling me what runs through the black pipe and where abouts on the engine does it go?

so i could get 8 instead of 6 mpg on full chat lol
my octy does 5.1 aparently on boost...

its one of those things most accept that the mpg will suffer and simply sack it off aswell

also its not an egr as no exhaust gas goes in it (as im sure your allready aware)
