So since I last posted I quit work, sorted out some family business hundreds of miles from my home, and got the engine running

Videos to follow when the engine is broken in and tuned.
I have to fabricate a proper method of securing the throttle cable, then break in the engine on the rollers.

The inlets are far too short so I'll be getting some silicone hose to extend the tract, then get some aluminium tube to fabricate the correct length.

So I stuck it on the rollers to break-in the engine

Initially it brought up the problems with cooling, there was a huge airlock in the system as a result of the electric water pump.
So I pulled the thermostat, removed the mechanism effectively leaving a restrictor disk. I've been told that this may not be good as there are different coolant routes through the head depending on the coolant temperature so I may have to revisit the this later - I'm hoping that the flow of water will be enough that its just going to be flooding the passages with a flood of water.

Yesterday I gave it about an hour break-in, (2500 - 3500 rpm with a medium load on the rollers) the highest water temperature I saw was 98degC.

Once I can get back on the rollers I'll start mapping it. This is going to be a few weeks off yet.

i was told to run without a thermostat and use a restrictor, when i fitted my electric water pump i used a digital controller which had been factory wired with the output to the pump the wrong way around which made the pump run in reverse and managed to cool the engine all day long at slow speeds but overheated badly when pushed. i was sent a new pump and controller and now even when pushed hard the temp keeps nice and low. i had to tilt the pump while running and filling at the same time to get all of the air out
hope you get it all sorted out and looking forward to seeing what power you get

Thanks for the info. During the break-in period the water temp was in the high 80s and no higher.

We shall see how it works when I do some power runs.

Incidentally, what sort of ignition advance are you seeing?

Nothing else to say here but, its climbing out of the rollers and spinning up the wheels.
With the Sun set to lb/ft it went off the 120ft/lb scale from about 4k...
I drove the thing hard with over 30degC inlet temperatures for about 5 hours on the rollers today.

Only a few oil leaks.

I need to find a rolling road with knurled rollers.

The latest problem I have...

The compound my Compact was stored in was broken into and my suspension, ECU, seats and harnesses, switch panel, bumpers, and door cards were stolen.

I think that this car is cursed.

I've been busy with some other projects, but I am not resolved to get this car moving on - and continue the development.

Don't hold your breaths though ;)

I have finally realised that I will not have time to finish this project, I was determined to not let the theft from the vehicle not effect my determination, but I just don't have the time and the drive to do this anymore.

The entire project will be going up for sale, if anyone would like the engine I'd be open to reasonable offers.

So gutted to see that you won’t be able to complete this build! I’ve been checking here for updates on it for years for ideas on my own build. Have sold the car then now or have you not got that far yet?
