The reason ferrari introduced periscopic exhaust pipes in 1998 was not to create downforce, it was purely a thermal problem with the materials at the time. Later it was found to bring some nice benefits and got widely adopted by other teams, though. Blown diffusers had been a thing for decades (albeit in a different manner than the 2011 version), but with the massive rev range in the late 90s, teams started to move the exhaust a bit away from the diffuser because it was making it too sensitive to throttle response. So that was another reason why the periscopic pipes eventually took over.

Oh the ear splitting goodness of the blown diffuser era. Gone but never forgotten.

Great video. Adrian Newey also attempted blown defuser in the MP4/15 and MP4/16, which is why the engine sound was so unique, definitely check out that sound, to me it was the best sound from an f1 engine.

Whilst true that he was using the blown diffuser back then (and also in the williams days), the Mclaren actually sounded so different because of it's beryllium pistons, which where very light weight, meaning a longer stroke could be had, providing more torque. Ross Brawn was very impressed with this and couldn't work it out in the beginning. Brilliant engineering.

Yep. This is a load of revisionist history. If you went to a race in person in 2010 you'll vividly remember how trashy these engines sounded.

Excellent explanation of how blown diffusers work.

Kind of off topic but one of the differences between the Super Marine Spitfire MK I and the MK V was the positioning of the Merlin's exhausts straight back which provided the thrust equivalent of another 50-60hp. On the MK I they just dumped the exhaust straight out the sides.

This is why top fuel dragsters have their exhausts tilted towards the top of the tyre. Creates more downforce for them. Motor Sport engineers are just crazy with the ideas they can come up with. Loved the sound of the blown diffuser.

beautiful video, first time i finally understand how the blown diffuser worked.

Would be nice if this and the double diffusers were allowed on the new ground effect cars.

Thank you so much for the great visualizations! I read Adrian Newey’s book several years ago on a navy deployment with little to no internet. This did wonders to answer questions that occasionally pop up in my head still.

Would've been good to touch on the coanda-effect exhausts that were introduced in 2012 (I think?) when the FIA stepped in to stop the teams placing the exhaust outlets right by the diffuser. Another excellent bit of design work there!

This video exactly dropped on our new years eve (GMT +8:00). Gonna wish happy new year everyone!

Pops and bangs.

Happy new year guys, thanks for the awesome vid to start the new year with.

Fun fact: the upward-swept "zoomie" headers on Top Fuel dragsters actually function like rocket engines. At wide open throttle, those 500-cubic inch (8.2L) supercharged V8s spin up to 8,500rpm, cramming air into the cylinders at 65psi above atmospheric pressure (which is insanely high even for a modern ball-bearing turbocharger spinning at well over 200,000rpm, let alone a belt-driven Roots blower), along with 1.5 gallons of 90/10 nitromethane/methanol blend fuel per second. These engines see mean effective pressures up to 1,450psi and power figures in the neighborhood of 11,000hp. The sheer amount of reactionary mass being blasted upward and slightly rearward out of the exhaust pipes is capable of producing almost 1,200lbf of thrust, mostly directed downward to squash those massive ultra-soft drag slicks into the pavement.

I want the feeling of F1 from the 90's back, the direct safety of today, and the regulations of group-b rally. Let's see what actually engineering can do.

Happy new year mate! Awesome video once again, got one question... What music was used!? Sounds so good

Imagine how fast F1 would actually be if they stopped banning tech.

Lovely video. When this was banned, teams tried monkey seats which also converted exhaust gases to downforce

Well presented gentlemen. Thank you.

Happy New Year Scott

The blown defuser👌 We had what was called the cricket bats at RB, made out of inkinal, the same stuff that was used on the space shuttle…. One guy from R&D went to NASA to look at how they used it.

Love me a good video about hot blowing and tire squirting lol, love these types of video can't wait for more in 2023!

They can make blown venturi tunnels to use together with normal exaust and adapt the quantity of exaust through the venturi tunnels according to their speed

It's like a simple mixture of anti-lag and the Meredith Effect... Using hot escaping gas to generate usable thrust!!! Pretty cool

I love the blown diffuser sound! Bring it back please

The RB7 is in my opinion the best sounding blown diffuser car with the 2011 Renault being close second.

I love that Scott was unable to say "hot blowing" with a straight face.

I finally understand what "blown diffuser" means. I used to think it meant that something had gone wrong and "blown" up 😂

Technically it's not a suction effect, it's the air above the car that pushes it down. Great video, thanks to Scott and Scarbs for the great explanations. Happy new year to all of you!

@batman9823

I'm not going to get into an argument about it but it is absolutely about the car being "sucked" down, not being "pushed" down that creates downforce. Basically F1 cars use the principles that enable planes to fly in reverse. Intuitively it would seem they are being pushed down but they are actually being "sucked" to the ground. This is the way these principles described work, otherwise pushing air flow at the bottom of the rear would create the opposite effect of "pushing" the car upward and, thus, decreasing downforce

Thanks for always given nice videos to explain things. Just curious.... yes Downforce is created over the difference of air pressure on the car, but it does not mean a car is being "sucking" on the track but air pressure travels from high to low, so the car is being pushed into the track by the high-pressure on top

A very late reply, The Renault RE40 used a blown diffuser way back in 1983. It's exhausts exited under the car into the diffuser.

5:13 Machine loud: Men cheer 😂

So hot blowing was technically an afterburner effect. the fuel was Ignited as it left the combustion chamber to blow out the exhaust, only not to thrust, but to create active air to let the diffuser do it's job properly

Some jetski racers have their exhaust pointed out of the front of their hull. Creating a vapor barrier between the hull and water surface. Decreasing friction.

Real reason why the FIA got rid of the blown diffuser was to prevent triggering a panic attack for young spectators who have lived through all those “active shooter” events. PTSD really was killing their ticket sales.

pure genius! there still is some innovation possible, even if you can only get it off for a couple races or a season until FIA squashes your dream tech

How about the rear tyres when using this exhaust configuration? Does it burn?

How much flow pressure/velocity was needed to be beneficial? Ignoring weight penalties so for conceptual sake only, could you rig a system that charges during braking or even tap off the exhaust to charge it and can be activated that releases air either through spring charged compressor to fill a mini tank of air or just spin a turbine/blade to send flow where it needs to be?

If we're talking about aerodynamic advantages from the past 30-40 years, you'll find A LOT of them come from Newey/Red Bull. Also, BIG AGREE on that raspy sound. Hah, literally just changed the thumbnail.

Retty neat! How do you called this backfire exhaust system?

It’s like god mode on the type r’s SI’s ST’s etc …

Your description of the pressure difference above and below the car (commonly referred to as longer path theory) is a common misconception people often associate with how planes fly as well. Ignoring the chassis for a moment, the front and rear wing of the car are airfoils (wings on a plane are also airfoils, but in the case they are being used for downforce rather than lift). The assumption you're using assumes that two air particles from the atmosphere separate at the leading edge of the airfoil and then join up at the tailing end. Since one air particle has a longer path, it must have higher velocity, and thus a lower pressure. We cannot assume that the air particles will meet up again at the tail end of the airfoil, as this is not a realistic assumption. Also if this were true, symmetrical airfoils would not produce any lift. Downforce (and lift) is generated from redirecting or turning the airflow. In the case of the F1 car, the air hits the leading edge of the airfoil and is directed upwards as it moves along. The airfoil exerts an upwards force on the air and the air exerts an equal and opposite downwards force on the airfoil. The product of this interaction is downforce. I apologize if I am coming across as condescending to anyone, but I am just seeking to provide more accurate information to people

Wow, after all this time I finally understand what a blown diffuser is.

F1: *uses exhaust for more downforce* Top Fuel Dragsters: "First time?"

Happy 1M🎉

Using exhausts to make cars faster isn't new.. that's how turbos work!

Another amazing video

F1 teams: FIA: so you have chosen DEATH?

I heard Romain Grojean talking to Nico Rosberg i think that you had to keep the gas pinned to want the grip and they could not lift in the fast Conners cause they lost a lot of down force

The amount of cuts in this video make it sound like a ytp 😂

By 2014 they made sure there'll be no form of exhaust blowing of the diffuser by moving the exhaust aperture to the center and top of the rear bulk head of the cars.

Man, I want a very nearly open-class F1. No MGU-H, and no primary downforce fan cars.
