I wanted to share some news and how the season went for us this year.
All in all we had two 1st places and multiple 3rd places in our class and we are quite happy with it for our first year together in the cockpit. My co-driver had his first rally season ever!
We hope that we can improve our driving in the next year as we are still a little bit slow in the first few stages of every rally.
Unfortunately we had an issue with our dogbox in the last event and were not able to finish the rally. Propably some bad dog rings, but we were expecting that to happen.
A lot of things will happen this winter. We will revise the gearbox and change some bits on the engine: new rod bearings and changing the current exhaust cat cam (293°) to a 282°. Inlet will stay 300°. This will help to improve torque and power in the mid RPM's. Currently we need to rev the car to the limiter to get the full potential of the engine, which can be tricky on some rally tracks.
Next thing that will be done is a full aero package that is developed and built by me. For the front of the car I already built a Kevlar/Carbon splitter. Additionally there will be two different sized canards on each side, some air dam in front of the tires and a small air dam on top of the splitter.
In the rear we will have a big wing (s1223 airfoil) that will be placed backwards. But I still need to simulate and calculate how much to have a proper aero balance between front and rear.
The rear wing itself has a width of 1400 mm and a chord length of 200 mm. In free airflow it makes about 31 kg of downforce at 100 km/h, 54 kg at 130 km/h and 81 kg at 160 km/h. At Vmax which is 176 km/h for my car it should be around 100 kg.
The parts at the front of the car still need to be simulated which will be done in the next weeks.
If it works out properly on track I want to offer the same parts to everyone in future.
If you have questions or suggestions let me know! I appreciate any input.
