    Finished off machining the flywheel. I've probably taken about a kilo off of the weight. I also 8 doweled the flywheel and crank. As I didn't have a jig, I used my indexing head to drill out the flywheel and then spotted through the flywheel to drill the corresponding holes in the crank.

    As the fan-shroud was dry, I fitted up the ignitor coil drivers and coil packs. You can see where I cut a hole behind the ignitors to allow air from the fan to cool the rear of the ignitor. This should work much better than just relying on a heat sink.

Decided to get the final outstanding little jobs on the engine finished off. Biggest one was putting some paint on the tin. To be completely honest, as time is thin I just gave it a quick rattle can to make it all the same colour. If I had a spare couple of days I might have elected to do a better job but at this stage I just want to get the bus back on the road.

    The other jobs were mounting the ignitors for the twin coil packs and putting the IACV and TPS onto the throttle body. With the ignitors I decided to forgo fitting heat sinks and make them air-cooled instead. A 20mm hole and a couple of washers behind them is enough to space them out a little and get some air flow over them.

    The IACV (Idle Air Control Valve) is a stepper based unit which is compatible with most modern ECU's I also have a two wire PWM style IACV that is compatible with Megasquirt units. The TPS is a generic unit that should work with all ECUs.

    The other thing that I started to do but ran out of time with is taking a little weight off of my flywheel. The aim here is to lighten it by a kilo or so. The stock flywheel is about 7.5kg, and the lightened ones available off of the shelf are about 5.5kg (12.5lb). If I can get it somewhere between 6 - 6.5kg I will be happy.

    Next job is to make a jig to 8 dowel the flywheel and crank.

    My Arduino Mega boards have arrived so I spent a bit of time establishing communication and uploading the firmware and baseline tune to the boards. I also connected Tuner Studio to the board. Still waiting for the components for the Speeduino before I can make it up.

    I also finished the hard piping between the engine and the disconnects that I mounted to the moustache bar. There will be a small flexible line that runs between the these lines and similar lines mounted to the chassis that run forwards to the oil cooler and filter. I'm hoping that these will be less vulnerable than the old flexi lines that they have replaced.

    I've also been playing around with some COP solutions and have found one that works pretty well. I've been trying out a variety of different COP's trying to find one that fits the Type 1 setup. I've still got a few more on order and will try them out before I decided on which one I want to use but one works very well as COP and the other works well as a CNP solution.

Managed to get an hour or so on the bus today. Started to make up the hard lines for the oil system. Need to get these done before I can get the gearbox installed as they will be a pig to got done afterwards. I made up a bracket to terminate the hard lines into and provide a solid mounting point for the bulkhead fittings. From this bracket there will be flexi-lines running across to another bracket mounted to the chassis. The bracket will be welded onto the rear bar. Need to pick up a bender as mine only goes up to 1/2". More

    Got a nice treat in the post today, a pair of overriders for the front of my bus. Got a super good deal on these as Jez from #TheEarlyBay arranged a group buy from Just Kampers. Top Bloke, cheers mate. ?

    Fitting the unit into the tank will first require me to make up a drip shield so that any rain that makes it inside the hood area is caught and directed down beneath the car. I'm currently on the lookout for a suitable steel pressing that I can adapt.

I ordered some extra (male and female) connectors so that I can also make up an extension cable for my Innovate LM2 wideband unit. The stock length LM2 cable is not quite long enough for a bus which means that road pulls need to be done looking at the LM2 in the rear mirror which is not exactly the ideal setup. More

    One more small step towards the goal; received some coil pack connectors for the twin coil packs.

    I'm kinda not looking forwards to making up the loom, which is kind ironic considering that my background is electrical engineering and I'm a qualified A-class sparky. Go figure. Guess it's too much like a busmans holiday. Still need to source cabling and overbraid and am waiting on the plugs for the O2 sensor.

    Still haven't done any work on the bus as I've been tied up making blower kits. Hoping that I'm going to get the bus running in time for #dubsbytheriver

  • No work on the bus this weekend as I've been busy making supercharger kits. Did receive my new lowered shocks tho. Decided to go for gas-adjust on the rear and regular oil on the front as running gas on the front tends to make it a bit bouncy.

I'm going for hard lines this time as my previous flexible line got pinched when I bottomed out on a pot hole. Basically hard lines from the engine along the moustache bar, then flexible hose across to the chassis and hard lines from there through the filter and cooler. Should be a lot more durable and means that there will only bet two small flexi-hoses in the entire system which will be very easy to swap out, which I generally do every few years.

    It's worth noting that normally oil hose only has a working temperature of up to 200 degrees (F) which is pretty close to the normal operating temps that air cooled run at. This means that it degrades a lot faster than it would on a water cooled car. The hose gets hard and can fatigue and crack. It's worthwhile checking and changing your oil hoses every few years

  • Been busy building superchargers this weekend so not much progress on the bus. Did manage to get the drive shaft rebuilt tho. Small victories. Just need to fit it now (along with the gearbox).

Finished off the fan shroud yesterday. Welded in the patch to get rid of the air filter pressing and welded on the 'venturi' to the rear. I also had to change the fan from a doghouse fan to a non-doghouse type of fan. I was hoping to run the doghouse fan for the improved air flow but is was just a couple of mm too wide to fit the fan housing. I also took the time to close up the gap between the fan and the rear inlet as this will allow air pressure to bleed out of the fan housing back into the air inlet path ruining the flow of air into the fan, effectively making the addition of the 'venturi' worthless.

    I mounted the coil packs up and fitted the fan shroud to the engine to check the plug lead fit. I'm pretty happy with the way the plug leads sit and will not need to trim the lengths down to suit. The lower plug leads fit nicely under the clips for the rocker covers and once dressed in with the top leads will sit well enough away from the exhaust.

    There's still a few bits to sort out with the lower tin before it's ready to prep and paint.

    Then there's only 100 other jobs to do before it can go in.

Decided on a location for the coil packs today - on the rear of the fan shroud. Had to flatten part of the pressing on the rear to allow the left coil pack to sit flush. I've drilled out the mounting holes and will use some riv-nuts once the shroud is painted. With the coil pack location sorted I was also able to buy the plug leads - all 8 of them!!! Still need to source some heat proof braid for the bottom plug leads.

    I also made up some tie down brackets for the fuel injectors / fuel rail. Originally I wanted to make a bracket that fitted to the underneath but after taking a look at the injector spacing I could not get two fixings side by side to keep the fuel rail square, so I decided to change the design to a more traditional type bracket.

    With the fan shroud out I decided to finish off getting it ready for paint. There's a couple of mods to do to it before it is ready such as welding up the holes for the plug lead clips, welding the rear 'venturi' onto the inlet and getting rid of the air cleaner recess.I also need to sort out fitting the 50 horse fan into the 40 horse shroud as there are a few air gaps that I'm not happy about.
