Start of 2020 Update

Apologies to anyone who’s been waiting for an update on any of the projects I’ve put on here – I’ve had a lot going on over the last year and writing up all of this information takes me a lot of time so has taken a bit of a back seat. None of that information has been lost and I hope to start catching up on all of this over the next few months.

Where we are right now :

V6 Mazda RX8

The V6 engine has been fully rebuilt and has been sat in my living room next to an engine crane for about 8 months now, Partly this is due to me not currently having a garage to work in and it being winter and partly due to being very busy last summer. But yes, the project is still ongoing and hopefully will make good progress this year.

Six million dollar welder

Is still on my workbench awaiting the last couple of bits. I’ve had to swap out 24V PSU’s a couple times as they couldn’t deal with the current of the new feed motor. It now works but needs the relays mounted to the panel so I need to remember to find 4″ of DIN rail.

DL180 Server

Is still working beautifully after the Arduino fan controller mod. It’s been hosting this blog ever since so something like 12 months now without a problem. It also provides the storage for my CCTV system.

Hikvision CCTV

I’ve got a couple of updates to write about expanding the system beyond the original one camera setup I wrote up last year. Using multiple cameras with network storage seems to be poorly documented and have a few interesting quirks but after some work I got it working fine. The biggest problem I’ve had since is when the local police asked for my footage following a nearby break-in I had to supply them on a 1 Tb hard drive! High resolution digital video takes up a lot of space!

Other Projects

I’ve had various other projects going on as well. I’ve started looking into using NodeMCU WiFi microcontrollers as sensor nodes with their own web servers around my house with NodeRed requesting the page and parsing the HTML to return the information I want. I can read the temperature sensor connected to the nodes and control the LED on the MCU from NodeRed. Currently the data is not stored because I ran out of time trying to get MySQL setup. I’ll write this all up at some point

Raspberry Pi’s – I seem to have collected a selection of Raspberry Pi’s somewhere along the way. I have a Zero, a ZeroW, 1B (which in a different life I turned into a PoE CCTV camera), 2B and 3B plus I think somewhere there’s another 2B. I really should do something cool with them!

Wooden storage box – I started restoring a large wooden box some time ago. The box used to be in my granddad’s workshop as a toolbox for many years and before that I gather it belonged to his uncle so it’s been around for a long time and has suffered a bit with use and age with some areas with woodworm damage and the rope handles badly degraded. It has also been painted brown at some stage so I’ll need to get that cleaned up as well. I intend to restore it to a ‘usable’ condition so rather than trying to make it as new just tidy it up, repair the damage and make it solid enough not to degrade further but still look like the well used item it is.

Subwoofer project – Has been in constant use for ages despite never being technically finished. I really need to actually finish it and write this up!

There will be more but I think that’s enough update for now – rest assured I’ve not stopped! Especially since this morning another turbo arrived in the post, the fourth I now have here….

Living with a Scirocco 1.4 TSI 160 (118kW)

So recently I finally decided it was time to retire my previous long suffering car – a 2003 1.4L Mk1 Seat Leon I’ve had for 10 years! When I bought the car in 2009 it had 62,000 miles on the clock, now it has 198,000 miles on it and needs to be run on 10W40 rather than the specified 5W30 just to stop the engine rattling. The Seat did well but it had a hard life including 3 years commuting 400 miles a week and had got to the point where I was fully expecting it to fail sooner or later and wanted something that wasn’t as underpowered.

So I started looking about for another car and the new style Scirocco caught my eye. After looking for a while I found a decent condition version with reasonable mileage, service history and not reaching a high bid. Detail on this car was a little lacking as it was just described as a 1.4 TSI but the car had no engine/spec badges (a factory option from VW) so I wasn’t sure which version it actually was but on the basis it wasn’t advertised as the higher power option it would be the lower power turbo only 122 bhp model. So I went for it and got it for a decent price. When I arrived to collect it having never actually seen it before I checked it and found the identifying sticker in the boot which showed the power as 118kW, this is 160bhp so I’d got the more powerful one.

Something like this one.

This is both a blessing and a curse because while obviously it goes better the 160bhp version also have a reputation for unexpectedly experiencing catastrophic engine failure.

That said always take forum posts on the internet with a pinch of salt – people rarely take to the internet as much when their car works perfectly.

By this point its too late to back out so I’m now the owner of a Scirocco with a 1.4L engine! So now I start looking into things I need to watch out for. The engine is the first interesting thing here as it’s both supercharged and turbocharged to give a much better low down grunt than expected from such a small engine with supercharger boost while still having a wider power curve by the turbo taking over at about 3000 rpm and working higher up. The engine peaks out at about 1.5 Bar of boost (22 PSI) from the factory. This system obviously adds complexity and potential points of failure with various valves and clutches to make it all work so a number of things to keep an eye on.

VW Technical guide to this engine available here

Clearly we’re playing with a fairly highly strung engine so my first thought is what the maintenance schedule on these was like. People tend to ignore their cars so long as they keep working and from my previous 1.4 VW engine in my Seat I’m aware they have some issues with oil consumption. On my first look at some of the reports of damage online most seemed to mention failures that could easily be a result of oil starvation. Again, something to keep an eye on.

Moving beyond the engine that car itself is fairly advanced as well. These cars come as standard with adaptive suspension designed to react to road conditions. It has four sports seats which are very comfortable and the boot is quite reasonable for this type of car. Internally the Scirocco is very similar (depending on model year) to either a mark 5 or mark 6 Golf but is a bit less practical due to the style of the vehicle and lower roof line. That said I’ve had four full grown adults in mine and while it’s not hugely roomy it’s comfortable enough.

Now for the the but – I think mine was cheap partly because it has none of the extras. It doesn’t have cruise control, it doesn’t have HID headlights, it doesn’t have the more common 18″ ‘turbine’ wheels (I have the 17″ shown above), no DAB radio and no bluetooth. Other than the twincharged engine its a basic model and for most people that would be all there is to it but that’s not how I work. I will improve it as I go along and hopefully record how I do it all on here!
