King pins?  My father told me it was a good day when those things became obsolete.

And he was right, for pretty much every application.
In our application where high mileage durability is not an issue their specifics suit us well. We don't need upper and lower control arms and so the amount of superstructure hanging out in the wind is minimised

The motor went in for a test fit on Friday....

<iframe src="https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2Fyesyoubloodywill%2Fposts%2F2686809114748818&width=500" width="500" height="668" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowTransparency="true" allow="encrypted-media"></iframe>

There's a couple of things that needed to be sorted out. In the motor swap we had to go with a radiator instead of the total loss cooling system with the 60 litre water tank. That meant we needed to work out a way of ducting air. A fan sits on top of the radiator pulling air through it and sending it out the louvres along the spine of the car. If we didn't do this it would be coming from air heated by the headers, we didn't want that. When we took the car out in 2018 I had made a fibreglass air box but due to the rushed nature of it all we ended up having to cut the duct down because it was fouling on the cowl......

Yesterday I made a new duct from aluminium to take air from behind the throttle bodies.

Pumping hot air out of the car will cost us in aero by increasing turbulence so I have a few remedial ideas to try and claw back some horsepower in drag. Years ago I bought some stainless steel bowls with the idea of using them to cover the steering components as mentioned above. The bowls were close to perfect but needed to flat bottom stretched so.... I mounted one on a platter on a big sander polisher and put some plasticine on the flat bottom. I spun it and used a putty knife to turn it smooth. Then I cast it in plaster, I've smoothed the mould and will cast some out of fibreglass, they will screw straight to the inner (stationary) moons on the front.

In a week or so I should have the steel foils I am getting made which will fit around the front axle and also cover the tie rods.

At the other end I'll use the same profile foils to cover the rear axle. If time permits I am going to investigate filling in the void inside the rear radius rods ( The A Welker budget aero boost!).....this however is complicated by the exhaust which now exits the side of the cowl and travels down each side to where they dump behind the rear axle..

Hopefully these measures will win back some of the aero we have lost by going to a radiator and sidewinders.....

It would be really interesting to see a photo of what you've done. Thanks for continuing these updates.

Ha! I knew what the C4 comment was about but not being a racer, I had to look up C16.

Back to the point...where are the pictures of the car mods???
