Number Plates and a thought
Discussion
I was just reading another thread aboiut Number Plates, fonts and plate size, and that the idea of reducing the plate size aids air flow to cool the engine, but it is illegal.
I had a thought (no don't panic), what if you took a normal number plate, and with the right tools cut out the letters and numbers, then covered the back of the plate with a black woven mesh.
Would this aid cooling, as air could now go straight through the cut out letter/number shapes, and secondly is this illegal?

Think you may of misunderstood, I mean cut out the letters and throw them away, then using the reflective plate, back it with black grill. The air then gos through the letter cut outs, and the plate is still reflective.
So if the regs say the background must be yellow or white it still will be, my question is rather, what does the regs say about the letters and numbers it self.

It would be illegal because the regulation says that the background to the index number must be reflective white at the front and yellow at the rear.
There is no regulation about the size of the plate as long as the characters are regulation size.

The holes should mean that the engine will rev higher and produce more power whilst simultaneously reducing emmissions and fuel consumption. They will also make the car undetectable by Gatsos and result in a substantial increase in downforce and top speed.
Hmmmmmm.......
The next MAX POWER accessory has been invented! (Well, it's better than blue windscreen washer lights!)
On a serious note, honest, I am actually cutting my front plate down as it is a short number and the additional cooling should genuinely benefit the car IMO.

A cunning plan, but going back to my fluid dynamics days I suspect the airflow increase you would get would be very small (it's likely that there would be also sorts of recirculating flows, etc., behind the plate) and maybe not worth that level of effort? Cutting down the plate should achieve a good reduction in air flow though.
I like your thinking though!

Interesting. Fluid dynamics, back pressure, ground force effect and that French chap Benulie (can not spell) suction effect of fluid (and air) over a surface if two surfaces are in close contact.
Ahhhh, must stop thinking to much.... must do my job....must just saw bit of end of plate....head hurts....

You can! Just expect to be pulled by the rozzers for failing to comply with Construction & Use Regulation 123, Para. 4, subsection v, note 1. Or whatever ;-)
The plate MUST be a flat plate mounted vertically. It's only tradition that allows E-type Jaguar drivers to get away with the vinyl plate wrapped around the bonnet. I actually had one on my Spitfire years ago, but the Police couldn't read it at 30,000 feet anyway....

Why can't we get a sticky one and put it on the bonnet ?
Honest question.

Sorry, I should have said that the regulation states that the characters should be Black on reflective white or yellow. I presume that if you cut the characters out, they would no longer infact be actually on the reflective background and therefore you would still commit an offence. Whether anyone would actually take you to task over this, I couldn't say (a jobsworth might to make a point).
The worst you might expect would be a nonendorseable FPT or a Vehicle Defect Rectification Notice, which are a bit of a pain in the ar5e
Ahh, thanks Madcop, I think I will just cut the plate smaller.
