Let's have a closer look at the team "Tuning Akademie" that I have been working in and check how we fixed our Aero Issues with little budget and simple methods.
How did we reduce drag and increased downforce at the same time?
How did we solve the cooling issues?
Which methods did we use to succeed?
Let me know if the video helped you and what other questions you have about race car aerodynamics!

Brilliant video! An engineer's dream to fix problems simply with knowledge of flow physics and good judgement, rather than relying on sophisticated tools.

The over-surface NACA duct problem seems so evident in hindsight, yet must require experience to detect. Thanks a lot for sharing.

@camerone397 Год назад

very informative video. goes to show that all the fancy software and analysis won't do you any good without fundamental knowledge and the ability to test empirically and improve based on that. I'm not in the full time workforce yet but that's definitely something my school's Formula SAE team could stand to learn from...

@panacelium 2 месяца назад

Great work! I now want to improve the aerodynamics of my vw scirocco 3 to reduce drag. I have 2 ideas 1) Use the factory air intakes located on the sides of the front bumper and make air outlet holes in the wheel fender 2) Make a grille in the skirt of the rear bumper so that the air from it goes directly into the low-pressure zone behind the car, thereby reducing it. If you can give me some advice, then I would be happy!

@alexanderklenk2195 2 года назад

Does the effect of gravity on the flow-vis ever cause issues? Or are the aero effects always much more significant?

@BSport320 2 года назад

I mean once you sprayed it on the car, it should really start driving, overwise it will dry while the flow viz is running down. Same goes for hot surfaces (bonnet etc.) It will be dry before the car starts driving. But as soon as you are driving the flow effect is more significant than gravity.

@S.AlienLife 2 года назад

Thanks for insightful video’s!! Many engineers dream of being in the hothouse of intense pressure of F1… you had (it seems, a relatively short) time in F1, and then left. So whats more challenging, being a high-focus specialised F1 engineer or being a freelance engineer with a high diversity of challenges & opportunities? Also, would you go back to F1 (or LMH/LMDh) if approached by a factory?

@BSport320 2 года назад

I've been in F1 for 3 years, which is normal looking at my work mates. 4-5 years is regarded as a long time in F1:) Anyway, I left because I wanted to start my own business and enjoy the freedom and variety of projects now more than being specialized on a particular area. Never say never but currently I am pretty happy being self-employed.

@petertimowreef9085 2 года назад

Really enjoyed this video, good combination between theoretical knowledge and understandable practical applications. Why kind of engine were you guys running, why not the NA V8?

@BSport320 2 года назад

Thanks! The NA V8 needed 3 times more fuel per lap which resulted in too many pit stops. The better choice for long endurance races was the V6 TDI.

@petertimowreef9085 2 года назад

@@BSport320 A diesel?! Interesting! Maybe you could do a video about how racing with a diesel engine is different from petrol? Just a random idea, I really appreciate that you take the time to answer my questions.

@smartiesnestle6679 22 дня назад

What year were you doing this? I really wanna do this but I live in Canada. There’s no road course or circuits.

@flizndfor 2 года назад

Cool. What was the difference in lap time? 😬

@BSport320 2 года назад

That's not easy to say because the video summarizes one year of updates and the conditions at the Nurburgring are different every time. But with aero updates + some software updates for the engine, we were able to reduce lap times from 10:10s to around 9:50s (25km VLN track)

@indopleaser 2 года назад

question: are the old open top CanAm cars way better aero-wize? less frontal area, hatchback shapes are better then coupe shapes. i know their are easier to design and cheaper due to no doors or roof. thanks

@Moli571 Год назад

Seems a choice of compromise: open cockpit so less drag, more flow to the back, but less surface to guide it. Even if the former seems to me the less relevant. Viceversa for every point for the closed one

@Jon.S 2 года назад

Great Stuff. A question on the NACA ducts in the floor....you said they had a "step" which was preventing them working efficiently.....how big was this step? The pic you showed had them mounted externally to the floor, with the "lip" on the outside, so is that step (i.e. the 2-3mm or whatever the thickness of the plastic is) too small to be a problem?

@BSport320 2 года назад

The step was 2mm and separated the flow. We could see that with flow viz and at the diff temperatures. After removing the step in front of them, the NACA ducts worked fine.

@Jon.S 2 года назад

@@BSport320 Hey, sorry to be a pain but I don't quite understand, do you mind if I email you to ask another couple of questions? Just really curious and surprised how much of a difference it made etc :)

How was the gas mileage

@damncritics 2 года назад

Why weren't you running front diffusers? Regulations issues or something else?

@BSport320 2 года назад

Simply no space. The RS4 has a large engine in front of the front axle and we were running very wide tyres.

@damncritics 2 года назад

@@BSport320 interesting. Would there be a point where you would sacrifice front tyre size for increased downforce? Or was that simply not a worthwhile tradeoff for a car as front-heavy as the RS4?

@BSport320 2 года назад

As a small team we couldn’t just simply change tyre size on an all-wheel-drive car. We were pretty happy with the mechanical grip and the static downforce of the nose heavy Audi was good anyway. But for more performance at faster corners it makes sense to have them. We worked on front diffusers lateron.

@damncritics 2 года назад

@@BSport320 Thanks so much for taking the time to explain.

@MartlRS 2 года назад

Turbo??? Was it not the NA V8?

@BSport320 2 года назад

It was the 3.0 TDI in a RS4 body. Better for endurance racing, 3x less fuel consumption, 3x less pit stops, quicker overall and much more torque for quattro.
