Ps what about the little pipe coming off the bottle of the inlet manifold? Whats its job?

[TheBoy]

Blanking little pipe off will likely reduce power, as ecu cannot measure boost, so goes failsafe.

Ah, thats the one I thought you meant - thats manifold pressure sensor (boost sensor)

The one on egr is vac to actuate egr

[conalnugent]

So blanking the egr one in effect will do nothing?

[conalnugent]

If the egr is blanked that is

Performance wise? Apart from a slightly better pickup during a gentle cruise, it'll do nothing except reduce economy slightly.  Assuming the EGR works.

Quick update.  Still waiting on a made up egr but managed to get my hands on a boost gauge. The wee pipe off the bottom of the manifold was slightly gunked up so cleaned that out. Its boosting up to 1 bar on the button. Wonder what it will boost when I get this new egr on. 

[TheBoy]

Hopefully, approx 1 bar

I think we got Omegatoys to about 1.4 above when we were playing with that, but had too many cooling issues. I think we knocked back to 1.2?

Omegatoy?

yup ran it at 1.4/5bar and was very lively, inlet temps got a bit to high for motorway work though,but short blast its great, i finally settled on 1.2/3 as a good compromise but bear in mind before i booted it every time i flicked the switch for the intercooler fan,and also did this before big hills ,it did around 40k like this apart form fan burning out, never had a problem,

lol and yes was roaring at the garage episode purely because the boy was in bed at the time an didnt realise what was going on!
 
now back in spain,just had a super tour on the quad up through river canyons and round lake! knackered now!

p.s and before the mrs used the car i always put the i.c. fan on and left it on just in case she got to lively with it which has been known to happen a great deal she aways came back and said why can i always hear the cooling fan even though the engine isnt running?
answer,oh its contrilled by a temp sensor dear till its been running a while it dont know the temp so it comes on automatically
