Very informative!

When Penske's IndyCar program got busted for cheating recently you heard people saying "that's so unlike Roger Penske, he's above that". I was like "What Roger Penske do you know? Penske has been pushing the rules for decades now."

No coil bind & valve float

When Agassi still had hair

Renault did not invent pragmatic springs. It was used way earlier in low speed marine diesel engines.

the lower pressure at low lift, means the valve seats are not slammed and beaten to fail.

My dream car... 06'

Why not use the Ducati valve train?

Penske and Chevrolet weren't the only ones acid dipping, most of the rest of the competition did it too. Sam Posey tells of the time his team left the body in the acid bath a bit too long. No problem until an official who had been looking over the car leaned on the roof with his elbow and it just buckled. "Oh, what's this" he said, we can't have this! Team Posey got permission from Chrysler Corp. to go to a local dealer and cut the roof off a showroom car and put it on the race car to get through tech inspection. Trans Am, with its strong factory backing at that time, tried anything they thought they could get away with to improve their chances!

Nice insight on every major racing series. As a Bangladeshi 🇧🇩, motorsport culture isn't big here. It has very niche fandom (we have Avik Anwar who races in UAE 🇦🇪 organized races), perceived to be a rich man's sport because of it's barrier to entry involving a vehicle. From 20 years ago, I have casually watched almost all the racing series you mentioned here except the Mazda series maybe. Been watching Formula E since around 2015, awaiting this series to become the pinnacle because FE is great to watch from an Engineering perspective.

I would like to see a video with and without sway bars on a car

what is name of song at 3:09?

Thanks for the content! I’ve been looking at antilag options for my 2017 Subaru STI and found the rocket! You explained it beautifully ..nicely done Brother!🤙🏾🤙🏾

Today, it’s push to pass.

wont the heat of the rocket be enough to melt the fins in the turbo? or heat it up the air alot?

Had 5, best car I've ever owned

I still have some questions so I might need to do more research. How does the engine exhaust gas reach the jet as off throttle the engine would be creating no exhaust gas? Wouldn't the jet need a constant stream of fuel rich exhaust gas to fuel it's combustion? If it is just a small amount of scavenged exhaust used by the jet, does this mean the engine runs rich constantly in order to supply the jet with a fuel rich mixture off throttle? If anyone could answer these questions I'd appreciate it.

Koenigsegg: freevalve. Renault: pneumatic-spring valve.

This is the definition of what racing is about

I’m convinced to this day they could have won the F1 championship. RIP Mark D.

Totally correct it's all that was avaliable to them at the time to be able to qualify, I remember seeing it on the track as a kid it was awesome

First introduced by Renault in the Lotus. To be more precised, a Matra and Renault invention. Because this invention is stock and displayed in the Matra museum in France. Back then Matra was still this amazing engineering compagny, which had a great competitions history. Often forgotten nowadays. Matra had the advantages, to work in so many types of industries, which allowed them very excellent engineering in different domains.

Interesting video there. But you don t say how much max rpm this new technology allowed Renault engines running in 1986. It would be an interesting fact to compare with other engine suppliers at the time it was introduced.

How many Daytona 500s did it win??

Desmo spring the best

The reign of Toyota and the rest of Japan ended because the West killed the Japanese economy for second time in a period of 100 years. Japan left the West in the dust in the 1890s and 1980s by the rules of Capitalism. Then, the West changed the rules. Japan is a special case, because it defeated the Western world at their own game not once, but twice! Japanese success revealed the true face of the West. West is the epitome of Narcissism. Narcissists are predators of Human Kind. Narcissists cannot co exist with different worlds, which is why they exterminate those. Japan has never recovered from the hit. The West is very rich. Josep Borell stated at the Academy of the European Diplomacy, that the West had to bring the ingredients back from the Jungle in order to build the garden. Africa is still trying to kick out the West and gain its sovereignty from the colonialists. World Economic Forum and Klaus Schwab invited Chinese Communists in Berlin at 1979. He instructed the IRON LADY to award the Communists by ceding Hong Kong. Before the Western attack Toyota was experimenting with SCCI engines and planned to enter the aerospace sector.

Almost no turbo lag on my '97 Tommy kaira M20b wagon, with the EJ20 and the tiny Mitsubishi TD04 turbo fitted and close-ratio RA gearbox. With the TK tune. Phew. Full 1-bar boost from 3,000rpm. Huge surges of boost whenever I stab the throttle. Brilliant vehicle. One of the best ever.

I wanna watch wec so bad but idk how to in America

Thanks for posting this video I’ve been trying to get a clear explanation on this for about a year now.

Cool! I think they used same kind of system or some kind of a hybrid in Rally cross and for example VW Polo WRC as the antilag was running whole time from start to finish line and was more like buzzin than banging, letting the Turbo have maximum pressure when ever needed but that was controlled like the Subaru pro drive system was, perhaps a cheaper evolution version of the rocket antilag. Im only guessing, but i may have ran inside the Turbo down pipe burning a flame there to create vacuum to suck the turbo in motion, resulting cooler running turbo to make more power as the cooler the air, the more the power.

What's about the desmodromic engine from Ducati? Wouldn't it work for F1 too? Or any racecar?

There is an Easier way of doing this, You could have a Bypass between the Turvo Intercooler and the ThrottleBody - Oh they mentioned it... Well, There ya go.

So why not just use progressive valve springs. I understand it still has the other flaws but wouldnt a progressive spring be better than a linear?

30k subs yet so good quality and informative content, hope the chanell grows fast!

Thanks for explaining the rocket, now i can build one and install it on my ‘04 volvo and blow it’s gaskets to smithereens

Who knows? We might even see some solenoid actuators that function as valve springs, camshafts, and rocker arms to the point of replacing all three simultaneously, similar to what Koenigsegg is doing with its freevalve technology.

but wait why isn't this kind of technology being used in cars? are they just too expensive or more complex than the simple spring valves?

Great now I want an 850 wagon🤣🤣

As an owner of one.... I could only imagine the hell they went through! About Sand and small tyres? It's not happening! It'll be like riding on oobleck! Constantly Sinking and steering would be shitty! I mean Real shitty!

Pneumatic Valve -Springs- 😉

The "New Mini" is no Mini at all. The key design element was the size, the "new" Minis are just vaguely styled on the original and copy a few elements. Even small cars are big these days because of safety regulations. They should have left the mini name alone if it can't truly be "mini". The size comparisons are laughable and that's before you even get to the AWD/"Clubman" behemoths. Don't get me wrong, the new version is a neat car, the looks are great and they handle vaguely reminiscent of the classic but they are not a true successor by any stretch of the imagination. BMWs not Minis.

Bro just like, use nitrous oxide for the valve spring gas so if it leaks the engine can be like "Oh this is fine"

*Best ever* break-down thank you

For how long does these engines running at 15000 rpm last. If lucky to the of the race. Most layman do not realize that all “race” engines are not expected to last 100 tho miles or 200 tho miles. In other words metal breaks, just a matter when. I’ll stick to my ole Honda put, put.

Just discovered your channel. Nice job on pneumatic valve springs. Looking forward to your presentations of other motorsport technologies.

❤❤

İ have another idea İ will not tell about.

When you get stranded on the side of the road because the nitrogen tank is depleted, that is when you truly ran out of gas.

And funny thing after all this is all human kind wants to see v8 and v10 back in f1

Desmodromic valves would do away with the need for a nitrogen tank. There's no spring with this system either.
