Hi again folks, is there any way that clean air can also go back down the nickle coated pipe down to the exhaust under big boost, thus losing boost pressure? I have just knocked up a blanking plate out of alloy in the workshop and I think it has definitely improved the whole job! I haven't blanked the Vac pipe cos I understand the theory behind the controlled air shut down and I've heard friends T5s shut down with the sound of a gearbox full of spanners. I haven't tried it in daylight to see if it has reduced my smoke output to that of a small power station.

I have 3 foot operated controls under my dashboard. The right one looks like a pedal but must be treated like a 2 position switch.On or off don't confuse the matter by treating it like a variable affair!

I posted this on another thread here:
I blanked my EGR system, and thought that it was saving fuel. I could not be 100% sure until I gave it a proper test. Now I have.
Every so often I drive from Riga, Latvia to Bergerac, France. It's 2900 km door-to-door. I compared this year's fuel consumption figures with last year's (also in August):
2009 Day 1: 8.9 (89 km/h)
2010 Day 1: 7.5 (87 km/h)
2009 Day 2: 8.9 (104 km/h)
2010 Day 2: 7.8 (100 km/h)
2009 Day 3: 9.3 (85 km/h)
2010 Day 3: 8.2 (81 km/h)
2009 average: 9.0 (92.6 km/h) in English: 31.39 mpg (57.54 mph)
2010 average: 7.8 (89.3 km/h) in English: 36.48 mpg (55.49 mph)
Yes, my average speed was down a little, and I can confirm that I drove for 55 minutes longer in 2010 than I did in 2009 (30:50 v 31:45), but that slower average cannot account for all that saved fuel. Can it? I saved about 13% or 36 litres or €40! That's 3 reasonable French meals!
Note: I've quoted fuel consumption in litres per 100 km as that's how my vehicle works; how I think, and it's esier once you get your head around it.
I've treated each day as equal so as to make calculation more simple. In fact:
Day 1: 1060 km Soviet Union: quiet roads with low speed limits and too many police.
Day 2: 1003 km Germany: all Autobhan.
Day 3: 800 km France: N roads only, no Autoroute.
Actual total: 2863 km
Also, it's nice only having to fill-up 3 times rather than 4.

Anyone have more to say on what clonky posted?
I was thinking of fitting this: Is that a bad idea, as it won't contain the valve that clonky's talking about?

Before i blanked mine off i wedged the flap fully open with cable ties. When the engine was turned off,especially when well hot after a run, as it came to rest there was a sort of rattling noise,like transmission gears jangling.
When the flap is operational it shuts off the air supply to the engine as its turned off, and you dont get the noise.

Is that all the needle in the valve is used for Clonky? - the smooth stop?
I blocked off my Vacuum tube to the EGR and I haven't noticed any difference to the stop. Have I just been lucky? |

Just stay with the original paper filter. Otherwise you end up having shitty deposits into your intake tract once again. Although this time they aren't sooty unless you drive behind a diesel...  |

I got my EGR delete kit ( blanking plate and gasket ) from Brickwerks this week.
I'm gonna fit a new K&N air filter and fit the blank-off this week. I'm a bit confused now whether the plate will fit my AXE 2.5 engine now. Only one way to find out- jump in with the spanners. 50/50 chance I suppose. I've located it on the top of the engine and it looks a cinch to do the job. Looking forward to finding out what the difference is. No more sooty shitty deposits going back into my air intake tract. I'll let you guys know what I think of the mod after I've had a chance to drive it around for a few days. |

Same guy reckons it gives a 7 mpg improvement as well.... The valve still needs to operate when the engine is turned off.It shuts off the air supply so that the engine comes to rest smoothly

"to block off you can use a pucker egr delete or even easier is stick a suitably tight fitting ball bearing up the vacuum pipe and refit, or even an old bolt." No need for fancy plates, just block the pipe. |

Just thought I post my findings. I have a BNZ coded engine. It is not the same lay out as the pictures in the 'How To'. The blanking plate was put in where the upper yellow circle is in this picture;
 The lower circle shows the other end of the pipe but is trickier to get to. Fitting is a breeze, just undo 2 star drive bolts. I took it for a test and within half a mile the EML came on, flashing intermittently. I took the blanking plate off and the EML disappeared. The plate was sooty when it was removed, even after that short blast. To be honest I didn't feel any difference in performance or anything else whilst the plate was in but as said I only had it in for a short distance. Getting it remapped tomorrow anyway so I'll just have to settle for that instead .MDIB |

The bit I blank off is below and just to the left of the oil filler spout.
Shiney bit of pipe comes from a flexi joint and connects to a bigger dark pipe.
 2 x 10mm bolts to remove a brace and 2 x 13mm to disconnect the pipe.
