Cheating in air restrictor?

[Scania]

there are some metal for moduling is breathable, about 30%. is it work to use this metal to make air restrictor, part of air would not through the restriced hole, but in the restrictor to suck more air?

[Lycoming]

...What?

If it's visible or obvious that air can enter after the restrictor, it will clearly be illegal.

but it is invisible
that material looks like a solid metal but 30% of surface is invisible hole, it is for plastic moduling.

that's y I said "cheating", it IS ILLEGAL, but invisible

Assuming it gets past scrutineers and assuming these holes are made by laser and invisible to the eye, I think they would soon get clogged up with dust and oil.

Toyota tampered with the restrictor in rally and it got them excluded from the championship. Max Mosley was president of the FIA then so I think the scrutineers would be avidly checking for the legality In f1

the toyota's 1 have movable parts, my concept is still a solid, but some nano size hole in the material

yup, this would be a problem, and how much air can pass the material is another.
So I hope someone who are expert in material can answer me.
for dust & oil, I think clean it after every practice & race by ultrasonic would be fix

If you are looking at this from a pure cheating perspective, then the engine adjusting (or being adjusted) for the extra air would be obvious.

They would have to carry more fuel to match the air. If not everything will just run hot and inefficiently.

Any professionally run series will spot something amiss. No low end budget series entrants would be able to afford it.

a small pieces of machined that material is around 2000hkd(1usd = 7.8hkd), it is not a huge budget if it is really work for a series u need around $500k hkd to finish a season.

As the restrictor as the 1.6T slower then a N2000 car, event after find tune, the max power won't more then 220hp, the heat & loading won't be a problem

but air flow sensor single will go crazy as u suck extra air after that.

Is this an existing material used for vacuum forming? If so please can you post a link?

IMHO This material would only work for a low volume of air extracted from a mould over a time frame of a few seconds. The holes will be so small that the friction/boundary/edge effects will limit air flow so there would be no appreciable difference to the total air intake on a car. It'd also get blocked very quickly.

You could do some simple sums by finding a data sheet for an industrial air filter that tells you the hole size and flow rates then extrapolate that to your tiny holes.

What if you block the air-restrictor with a tennis ball and then engine doesn't die? Busted!

Many sanctioning bodies will plug the restrictor shut and the engine MUST choke itself off.
I heard that in order to discourage cheating they are about to place you laying on the floor mouth gagged, hands and feet tied a few tens of yards in front of your vehicle.
Something like this

If plugging the restrictor shuts off the engine, then you both pass the inspection and save your life, if not well nobody cares about cheaters.
LOL

About the only 'legal' cheating would be to analyse your car aerodynamics and place the restrictor in a higher air pressure area.
If allowed then you can add some aerodynamic embodiments to increase that air pressure even more.

You may have to make something. I don't know of anything available off the shelf, but you may want to call EC monday. They may have them?
