This is a really nerdy question but.........

Would it be possible to make the 22b style adjustable spoiler work as a brake when the stop pedal is applied ??, similar to that of the new Mclaren Merc.

I saw it on top gear and wondered if it would be possible to modify one so that it assisted with the braking on a Scooby.

Pedal pressed and spoiler automaticaly adjusts to produce the resistance.

Just me or any other geeks out there see this a a possibilty ????

Anything is possible.

automodellistagt

yeah, it is possible. But why

even so yes, some sort of motor linked to maybe a switch linked to a the brake light wire would work

too much pimp my ride i think for me

RRH

it would probably pull the bootlid off

dmc1980

would you not be better with some sort of hydraulics, back to my nerd books

Possible, but about as much point as p*ssing into a hurricane

Why?

1) It's not in a vast amount of airflow in the first place.
2) The amount of angle you can get on it is pretty minimal.

I'm pretty sure you'll find the main purpose of the 'airbrake' on the merc is to help (mitigate) migration of the centre of pressure when braking at high speed. Again, I'm somewhat sceptical that the ol' scoob's barn door aerodynamics are that sensitive..

The not-so-short version is that when braking speeds well in excess of three figures, there's a lot of aerodynamics going on - as the nose dips and the tail rises, the car gains downforce near the front, looses it at the back - the centre of aerodynamic pressure moves forward and generally gets hurt in stability terms. If the nose touches the floor (unlikely in a road car!) the airflow to the underwing gets cut off pretty suddenly, resulting in some nasty side effects The 'airbrake' on the old F1 roadcar, and presumably the Merc (as it comes from the same gang) was all about controling airflow (presumably reducing pitch at the same time) to reduce the forward migration of the centre of pressure - reducing the likelyhood of a high speed end swapping moment.

WOW.....(that was the science bit)

It was just a thought, my mind doing stuff it shouldnt while watching top gear.

I'll just go larger with my brake upgrade i reckon

Cheers guys.

Actually Minty.
The thing to get is twin rotorx fusion reverser. You can get these at most LidL stores of failing that through E-bay. It can be linked between the spoiler and a quick flip switch on the dash normally by 1/4" tubing and a few grommets. ( make sure the grommets are brass)
You will need a copy of the latest "Aerodynamics and quantam reverse thrust monthly" published by Nasa. They have a good article about linking similar brake systems into Vauxhall Nova`s.
Good luck mate.... Personnaly I think its a lot easier just pressing the middle peddle myself.

every little helps, i'd get carbon stoppers if i could afford them then i wouldnt need anything else to assist in my very hard pressing of the middle pedal. just a thought.

Why don't you fit a sunroof and have that pop up and the doors open as well

i havent got a sun roof but i did think about the rear doors

Wear big gloves and stick your hand out the window.....

My feet are a bit sore from putting them out of the floor, maybe my hands could give them a break.

I got the idea from Fred Flintstone, i think he fitted the upgrade first

ive got a pair of giant Mickey Mouse gloves, I havnt tried it out yet but would assume that sticking one through sun roof and one out of window will result in a dramatic breaking affect as you hit the tree

Surely your mickey mouse ears would produce a fair amount of drag too if you opened the sun roof
