Update -as promised – about the steering column
This just leaves us to fit it to check whether everything is like we wanted it to be. We are pretty confident about it but you never know..
It’s just a matter of determining the right height and offset of the steering wheel.
Because we already had good experiences with dummy versions we tried to continue this way of working to make the seat supports and the steering column. No final version yet but just a steering column from a E30 316i and an old racing seat.
We are still looking for enthusiasts (m/f) to join our team. Most convenient is that you live in the big neighborhood of Geel (prov Antwerp) but kilometer eaters are also welcome.
Because we did not want to take any risk with the adapter piece for the Sadev gearbox – due to its high production cost – (this has nothing to do with a lak of confidence in our mechanical wizard Nick) we first made a simplified model with low budget tools.( saw and drilling device)
We still needed triangles to complete our front suspension.
We also have to pass the paint shop but we are able to start assembling and mounting front and reas axles.
Everything is on the shelf now. This means that we have reached a very important mental milestone.
As mentioned before, we have chosen an electrically assisted steering wheel where we can electronically control the damping and the speed dependence.
The wheelhouse itself is an original unpowered E30 wheelhouse with 34mm displacement per revolution. By applying a 2:1 reduction in the steering column, we arrive at 68mm per revolution.
The steering column is not ready yet so those pictures will follow but here is the wheelhouse.
After a very long period of sleepless nights we finally selected the coils.
They still have to suffer an endurance test but we finally decided not to go for COP’s for only one reason : reliability.
The space (diameter) is very restricted so it’s hard to find (small) fiitting coils
We studied the Denso’s from the Honda S2000 but they are too weak and because of the restricted space they soon start to warm up.
We decided to go for 4 Okada coils with integrated driver and the primary cables need to be as short as possible.
Some pictures of the differential with the Drexler LSD and 4.75 pinion/crown gear reduction
We made a hole in the cover to mount a temperature sensor (on the position of the speed sensor)
More pictures to follow when the cover is powder coated.
Since we still have to weld quite a few supports and other attributes to the bottom of the bodywork, we decided to make a new spit. This time we have thought about it much better so that the whole 1 is much firmer, 2 is on wheels and 3 is demountable and much better to store than our ill-considered first version.
Normally, it should now also be able to run smoothly with little effort. Hopefully we can confirm this shortly 🙂
Now we are going to think about additional supports so that the whole is universally usable, then finish with a color and then we can get back to work.
Today seemingly no more done than 4 holes drilled, nevertheless I spent a full day trying to get the jack supports in the sills.
