time for 11:1+ compression and atkins cycle via updated cams?
Mirage Hyper-Miler
also shorten the stroke for less displacement
Philia_Beartime for 11:1+ compression and atkins cycle via updated cams?
Funnily enough, we were talking about that today.
Is Atkins Cycle just Miller Cycle without the forced induction? Or is there a subtlety that I have missed?
It is very clear that the vast majority of motoring journos have no idea how either of them work.
Can you make it look like this?

Yeah, Atkinson is just miller without the forced induction
https://en.wikipedia.org/wiki/Atkinson_cycleYou would need intake cams with longer duration of open period
if you also have VVT you can switch between otto and atkinson at will depending on load
Mike is on the money, the late close on the inlet reduces the effective compression ratio on the compression stroke while maintaining the higher CR for the expansion stroke.

If you are looking long term to stop using fuel-petrol for a car, and want to invest long term, buy a good quality solar panel set-up. Then buy a nissan Leaf. I know a guy and for $4 of electricity, he gets 250ks. But the power is from coal fired. So buying a good solar panel set-up would make the electricty for the Leaf a lot greener". Plus they they have heaps of grunt, and are fun to drive.
Only one flaw in that logic is that the solar panels would have to be at his place of work.

LifePO4 battery bank at home charging from solar and then when you get home you plug the leaf into the pack and charge the leaf from the batteries at home over night

Brown coal electricity charging an EV works out about equal to a modern petrol car, from a CO2 perspective.
Black coal is better.
Solar or other renewable is, as you point out, the ideal.
I would just buy an EV if they were cheaper.

Figured that this should be my lockdown project, primarily because I am confident that I have everything here to finish it, and also because I am sick of driving the Falcon everywhere.
Probably about 4 hours of work so far, fitted in around home schooling.
My biggest area of indecision is whether to delete the power steering or not. I was 100% sure that I was going to fit the non-PS rack, until I worked out that the manual steer rack is slower.
I now need to decide if it matters or I am just too habitualised to chasing faster steering in rally cars.
It's probably fine to live with without PS, Excels are.
It runs. Solid but not killer day today.
PS delete was easier than expected. Hardest part was working out what was straight on the rack to line it up with the steering column.
It runs nicely, but hard to start. Not worried yet - the extractors are just sitting up against the head…
Got the front Konis in. Totally forgot that S40 springs are a larger diameter, it’s all good…
Need to buy some camber pins because the struts are modified to make the camber pins work better/easier, so now they only work with camber pins.
Rears are ready to go in. Will do it tomorrow when I fit the 2” exhaust that came from the crashed car.
SpacIt runs. Solid but not killer day today.

Konis should make a nice taught car iirc.
Time for lawn mower engine?
Philia_BearTime for lawn mower engine?
No, it will be hairy enough on the Barton as is.
Exhaust went on easily.
Filled gearbox with oil & radiator with coolant.
Fitted Konis to the rear.
Straightened the steering so that having the road wheels pointing straight and the steering wheel straight is actually in the centre of the rack’s travel.
I am pretty sure that this car’s steering was way off centre originally.
Cleaned a bunch of human slime off the steering wheel.
It is very close to being ready for rego, I think. Not that I can drive anywhere for the time being…
Drives and runs.
Hard starting was a lack of fuel… ? 20litres of fresh fuel and now it starts ans runs beautifully.
I think that it is rego-ready now, but I want to clean up the interior and fit a straight driver’s door first. Maybe a straighter driver’s side front guard, too.
Also need to take the air conditioning belt tensioner from the blue car, because the now-deleted power steering pulley is the tensioner for the shared belt.
Once I have done that, I will see if the AC works.
Happy with the ride height.
The noise from the exhaust is lower/better than I expected, but not sure if it will keep my wife and neighbours happy when I leave home at 5am… I will fix this if/when I need to.
Turd polished with reasonable success.
Battery… seems that I screwed up and gave away a Mirage battery with the Daewoo.
So now I have two Mirages and only one battery that physically fits in a battery holder. And I had to spend a while digging around to find it - turns out that it was in one of the Mercs. Such a simple thing, but it took a while…
