EGR Delete for better MPG - Lupo sdi

[Almonds 0]

Hi guys,

Been on here for a while. Just wanted someone to explain how to do a egr delete on 1.7sdi. In simple steps.

I brought this already on image attached.

Should be self explanatory given the shape there, but some stick it on the end of the egr pipe or in both places if they are same size / shape. (they do actually look different in that pic but might just be the angle).

The blanking plate is sandwiched between the egr and the inlet manifold, and / or the pipe and the exhaust.

Doesnt matter too much as long as it stops exhaust gas getting back into engine.

Bottom pic looks like the metal gasket I brought (£4) is for the bottom exhaust section.

How about blocking the air tubes from the egr valve top section? 

Thanks dude.

Nah... don't do it. Wont get you any more power. The only way is to gas flow the ram tubes. I've posted pics somewhere on here how to do it. Otherwise, just disconnect the vacuum pipe to the egr control solenoid (and block it).

Hi I've just bought a lupo 1.7 sdi do you know what the best thing to do to make it faster and perform better?

Clean all the soot out of the inlet. Mine had a huge amount of soot which I cleaned out.

Remapping. EGR valve don't affect fuel consumtion and output power, same like remapping, EGR just affects emissions qualitty.

But i also experimented with different injectors and the quantity adjuster inside the injection pump. The conclusion was that without egr, an active choke flap and plugged gas feeds, the only way to get a lot more power was by changing injectors- throwing in way more fuel than normal. Lots of black smoke, but wow, the increase in torque...!

However, would not pass MOT with them in. Someone else on here mentioned "rolling coal" after I did the experiments

If you're severely down on power, worth checking injector timing and fuel filter. A stock SDI is reasonably quick, never slow. Or clogged injectors... VCDS will give you all the numbers and injector balance.
