With a turbo the new 1.6l never have to rev to 15k more like 11k in race 12k in qualify.......thats it not like use to be

The rocket is so cool nwwo

The lotus f1 grabbwd two wins because they invented ground effect, giving them a huge advantage, don't think it was the engine valves

if he pumps up the coolant pressure won't it just go out the cap?? or do they have a special cap too

Renault

I subbed

desmodromic works well

Why are they not use another crankshaft for valves?

ain't nothing like racing a wagon

Ha ha ha ha ha the only way a 302 Camero could beat a GT 350 Mustang or a Boss 302 mustang was to cheat.

F1,WEC and Indycar

Now do a video on solenoid operated valves

new to this, how should i find the right size for my car

Thanks for the Tips.👍👍👍🏆🏁

You over-simplified the gas compression equation by reducing it to Boyle's law which implies constant temperature. In a rapidly compressed or expanded gas, such as the case in point, there is not time for heat to flow across the walls so the gas eqn (p.v exp n =1) is appropriate where n is the polytropic index probably nearer 1.4 (adiabatic) than 1 (isothermal).

Talk faster and it's rpm not rpms

On the infintesimally small chance that the guy that didn't get this during my interview at the UK atomic energy institute sees this - see I told you :) I hope your conviction that pneumatic valves don't have a camshaft keeps you up at night :)

Two things. 1) This reminds me of the cyclone generated inside a Dyson vacuum cleaner or an afterburner. 2) I wonder if it would just be simpler to have a solenoid controlled canister of compressed air connected to the hot side of the turbine. As exhaust gas pressure reduces, open up the air valve to keep it spinning, just hook that valve up to the ECU.

In a standard car, we already have an AC compressor and a negative pressure line... I don't see the problem of adding pneumatic valve train. Even if it needs changing every 50k km , and a small gas compression cylinder ,fuel saves from less power lost for compression might be justified. Maybe Renault will add this to the Clio and Dacia 🤣🤞

My Kawasaki has neither of those valve configurations...

Don't forget that too little force when the valve is seated can result in valve bounce as the valve returns to its seat at ever-increasing rates, as the engine rpm is elevated!

Good video thanks,, Hi from South Africa

How about the valve less and cam less engine

The only cheat is the last one. Other 2 are grey zones, but not cheating, as rules didn't say not to be legal.

It's just a jet engine with the fans and combustion chamber in a scrambled order.

I jumped from the stock 18mm rear bar to a 22mm aftermarket and it is crazy now whwn I turn super tight turns. Like my wheels lift off the ground I can can feel it but never see it myself since I am driving n one person told it happened. Idk if that is supposed to happen but the car handles really good and I don’t lose control it doesn’t feel sketchy but that can’t be right, idk what to do it must be normal is what I tell my self nervously when it happens it’s only one of the rear tires that lifts depending on which way I am turning . I drive a 2018 Honda civic si and I swapped out the rear bar to a whiteline 22mm might be 24mm I don’t remember pretty sure it is 22 n upgraded end links non adjustable (accord end links)non adjustable tho but they are beefy pure steel compared to the plastic stock ones they fit perfectly no forcing them in everything lines up smoothly so idk it’s gotta be right? Yeah it normal nothing to worry about mhmm

I loved all it that and I learned something I didn’t know plus you broke it down to people that don’t know much that was perfect all around 👌

They said we need multiple overhead cams, multi valves, variable valve timing. Has anyone seen how much power a top fuel dragster makes. Thats without two stroke technology. F1 like WEC is now actually just an ICE hating driver racing series which actually stifles ICE technological innovation.

The force to compress the spring is a side issue. Important number is torque required to turn the cam when in use.

Still an all time great. Car of the century if I correctly remember. I had a Cooper 1.3i MY92 in 2001, until it got fire in 2005. Most likely I am going to get another one soon.

...which is WEIRD because no one in their right mind should ever buy a normal, street-driven Renault due to it's horrible engineering.

In fact they don’t go beyond 11000 because of turbo/fuel flow. The pneumatic valves become really a must when the V10 Renault went over the 15000 in 92 and subsequent yrs.

Brother. I now must make this rocket you speak of and put it in my 4.3 blazer. But wait there’s more. It’s not a beat 4x4 it’s an xtreme brother

Are solenoid top ends a thing? I recall speaking about them for ag applications in the 2000s

When I was young (on the 70's) there was a model of Mini Morris with a modern design, more straight lined, flat haul, front cooling grille at headlight level, etc. I liked much more than the old one, but after a few years they started to get back to the older design. I wonder why they made that design throwback? That modern design don't appear on this video...

I can't remember all of the details offhand but a well known advocate of scooters back in the 60s rode an almost unmodified scooter in the Scottish 6days trial, and I believe he finished, there is a video available on youtube about it.

Why not use desmo valve like ducati does

Honda had traditional valves revving up to 22,000 rpm in the SIXTIES.

I was expecting you to discuss desmodromic valve systems as well , like Ducati’s. With them, valve floating is avoided.

If this is true, why doesn't top fuel dragster use this ? They make up to 12,000 HP.

Now I know the rest of the story

Have watched all type of racing & Indy Car for me has it all. Open wheel, amazing sound, great tracks & the unpredictability is what makes it the best series out there.

Please, NASCAR, put Harry Gant in The Hall Of Fame where he belongs‼️🇺🇸🏁33/7

The mini was the first professional works rally car

And I don't believe the claim of Renault making a 1200hp engine ever! Utter nonsense, unless it was some over boosted test only engine, their race spec twin turbo V6's never went over 700hp, and I have the specs in writing of every single F1 engine ever made, even if it was never raced. BMW made the most powerful F1 turbo engine @ 1400+hp (& a single turbo 4cylinder at that) and the most powerful naturally aspirated engine @ just under a 1000hp from the V10 era, and both times BMW was responsible for getting these engine/era's banned... unfortunately 😢

Well, thanks for your amazing video, very entertaining; But all that should be illegal to use even in races; why? because grocery getters DO NOT NEED IT; ALSO, the public should be informed NOT TO BUY TURBOed CARS!!!!!! Aside from ONLY ONE COUNTRY IN THE WORLD, Germany, with many highways with NO speed limits(aren't they smart -asses!!- pushing USELESS technical JUNK to ...well, IGNORANTS!!) NO O E needs a turbo to drive the speed limit!!! You need to tow heavy boats, well, go ahead then, you have plenty of choices LOL Paleeeeese, stay in school, kids.

Great video

Moron overhead cams don’t have rockers

Another that could have been added to the 90s would be the volvo 850 estate/station wagon from the btcc

So many bits of info I never knew... very cool! (Thank you for the VIIDEO & Research).
