Dunno about big power vxt, but she certainly has a big power vest!

This mornings drive (in my trusty Ford Focus TDi) gleaned a few nice pics of the Pyrenees, drove up them at dawn and was agog with natures bounty. Fabulous roads, fabulous scenery & bloody cheap petrol/diesel - get out there in your VX if you can.

looks great

Am back in the UK tomorrow, can't wait to swap cars. The Ford Focus has been faultless over the last 8500 miles and 5 months in Spain, and is like driving a serene floaty cloud (the shocks are somewhat tired), bless it's cotton socks. However the swap to Nippper's visceral character will be a wonderful change for me (weather permitting).

I bet you can't wait to get back to nipper Nev! And raining old Britain lol

Did a few checks on Nipper, changed the oil and took him out for my first 2016 run today. Lovely day, cold but bright, dunno what all you people have been complaining about over the winter - the weather seems fine to me

 

I was pretty nervous (clenched teeth and shaking arms!) for the first 10 or 20 miles, but its amazing how you gain confidence in these little cars so quickly. There was more grip that I was expecting for a cold day as well.

[siztenboots]

takes longer for the dampers oil to warm up, but great to use up a tankfull

[Nev]

Had the honour of having a road "tussle" with some sort of Aston Martin today. They are quite nippy for sure, but somewhat of an underling to a VX

 

[Nev]

It's a good job petrol is cheaper these days, I only got 180 miles out of my last Pro-Alloy (48 litre) tank.

Yeah but it's not as good as North Sea oil Middle East oil not as good I think

I've bought a load of 4" flexi ducting and joiners to try and build a clean air feed from the N/S ear to the airbox in the boot. Before I install it it I need to decide whether it's necessary to build a 3 pannel airbox or a 2 pannel one. So as a prelude to this, I've bought a small vacuum gauge off eBay and plumbed it into the inlet pipe to measure the vacuum that the turbo has to overcome. Just waiting for some dry weather so I can safely take the car out and stir it up to 8000 RPM and see what the gauge reads.

 

Does anyone want to guess what the vacuum gauge will read at full chat? Bear in mind it is pulling air through 2 fairly clean OEM paper pannels. I am quite intrigued about this myself.

 

The black 6mm vac pipe is instered into the red rubber bung (just left of the cam case breather vent):

Will you not be best going for a coupe back and a big roof scoop

[CHILL Gone DUTCH]

Then you could put as many air boxes in as you want then

Probably, but I'm not keen on losing rearward visibility or all the hard work to make/fit one! I guess I am just a lazy bones.

 

At the moment there is plenty of room in the boot to make a 2,3 or even 4 pannel airbox if necessary, so I'll do this small job first.

 

I have thought about a coupe back for several years.

Any guesses on how much vaccuum I am going to see in the inlet track?

I have no idea if that helps

[Arno]

For a suitably sized filter I'd expect around a 20mbar pressure drop when clean and >50mbar when dirty.

 

Do take care to measure away from the high speed airflow as this can create an artificial low pressure reading because the air rushing along an opening will create a low pressure area (eg. like a paint sprayer that blows compressed air over a paint nozzle and it sucks paint from a canister).

 

Something like a back wall of a filter housing is usually a good spot as the airflow is a bit more turbulent and not so fast as inside hoses.

 

Bye, Arno.

I've placed the sensor feed in a slightly poor place perhaps, however I expect it will give me a good rough idea.

 

Even with new filters, If I only have a 20mBar drop I will be astounded. Previously my (admitedly filthy) paper filters have been sucked in and collapsed on 2 occasions due to air demand:

[fezzasus]

But is that actually due to air demand or a poorer filter support than an OEM airbox would provide? The fact that it's collapsed at the edge rather than caused the filter to rupture in the middle would suggest that it has insufficient support.
