For others listening to AC that want to grasp his words wrt to respective needles go to classic mini diy - It's a needle comparison page. Allows you to see AC's words in graph form. It's been getting better and better. Beats the Blue book all day long. Allows you to select needles so easily.

Lovely van!

Excellent as always.

If it wasn't going in the van I'd say #1, but putting an engine in the van is a pain in the arse, and the torque will help a lot, so #4 makes good sense.

Hey AC thank you for your videos and that you are willing to share your knowledge. I do enjoy the twin content as I do have them myself and would especially like to see how your lambdatool acts while driving. One comment on the video-production side of things: have you noticed that your videos crank up the phone or MacBooks brightness up to the maximum? i always try to dim the display but it seems to have no effect on the video box. it seems that apple added some sort of "feature" into the color-sync tool that does that automatically as soon as it recognizes HDR-Content. So maybe you consider turning the HDR mode of in the video settings so your videos appear in regular brightness setting. since there is no toggle in the system settings to turn the "feature" off, only you as the creator have control over it. THANKS

Did the first mini have an afr gauge fitted?

Say how many times people have said "I have a Cooper S engine". And it turns out to be a regular mainstream 1275 block. And the other way around as well. Some show up with a genuine Cooper S they had for 40+ years. And it turns out to have been engine swapped for a non S unit back in the day!

Did you bother with a compression test on the twin one?

Having watched quite a lot of your videos, it seems to me that twin carbs are a waste of time and fuel, unless you're running a track car. The faff of balancing them, keeping them balanced and controlling the fact that they can push too much fuel through an engine during normal road use just doesn't seem worth it. Would you lose any performance by swapping a pair of HS2s for a single HS4 or HS6 with a heated manifold? It would certainly be a simpler set-up to optimise and maintain.
