After having changed our minds several times, we finally found a good solution to mount our Sadev properly on the S14 bottom block.
Because of the fact that certain parts have not yet been received, but also because of the lump sum of my loyal help / navigator for this weekend, I decided to carry out some infrastructure works in the R-Box basement. I am fully aware that this news item is of no value to most visitors to our site but it is rather in my own interest to show that I worked my own this weekend 🙂 To be honest, I must confess that my father took care of the paintings otherwise I would never have finished it so quickly, for which I am grateful!
With this so some completely useless photos
Together with Luc we spent a full day measuring and fitting to get the pedal box in place. At first it was suggested to have a piece of my legs surgically removed but fortunately I was able to turn the tide and we decided to make 3 round cut-outs in the bulkhead so that it is now possible to move the pedals if the brake cylinders used (compact or the long version) and still keep my full leg length.
The M3 body has entered the next phase. The welding work on the cage has been done. Today we have compiled our photo file and everything has been sent to Custom Cages to obtain our certification. The welding samples (on which tensile tests are done) had already been sent a while ago.
1000x thanks to Carl who sometimes had to wrestle himself into very uncomfortable corners to weld everything down to the last detail! Even though some places seemed unreachable at first sight, he always managed to find a creative solution to expertly tie the tubes together.
For the exhaust we did not dare to take too many risks because with a good design you can gain some power, but the reverse is equally true. Before you know it, you will lose 15-20 hp. Since the courses thermodynamics, physics and mathematics are not so fresh in our memory anymore and especially because we do not have the necessary test facilities, there was only 1 good solution … buy a good exhaust.
The first item on our shop list, the roll cage, turned out to be the easiest. In any case, we opt for a welded instead of a cage. So there weren’t many alternatives left.
We saw 2 possibilities. Either we let a recognized installer fully assemble the roll cage, or we go for the Custom Cages roll cage. The latter is a bit ikea-style, although the building kits are better documented there.
As mentioned earlier, the intention is that we will develop all electronics ourselves. ECU, display controllers, power controllers, ignition/coil drivers,….
To reduce development costs, we try to test as many concepts as possible with evaluation kits and test platforms (sample boards).
Perhaps the most counterfeit S14 part with as a result also a very different quality. Since finding an original Wethje airbox is looking for a needle in a haystack, unless you have a fortune for it, we were also forced to turn to the fake versions.
One of the first choices we made was the suspension. We not only took the quality of the product into account in our elimination, but also the availability of support and the distance to the manufacturer.
At first we looked at Reiger but due to the high price that was not feasible with our budget.
Only Proflex and Intrax remained. Both have a large number of satisfied users spread across different disciplines. Intrax is in any case the most chosen on track while Proflex has long earned its spurs in the rally event. Nevertheless, Henk was able to convince us to be a guinea pig with us.
So it has become the Intrax 4 road system with black titan coating.
The choice of the brand was quite easy for us. We chose AP fairly quickly because of the quality of their products and the good service of Guus in NL
The selection of the type of claws and the size of the discs took a little more time.
Fortunately, we could again count on the drawing abilities of Nick who expertly put various rims, discs, bells and suspension parts in Pro Engineer to bring them together in 3 D and see what can and cannot be done.
