Updated Project /Stability control

you know our methods and madness to well :-D

Its the method I am going to use to make a full width rear diffuser and front undertray too

goodman save yourself alot of money and have the enjoyment of creation

rest assured there will be a project thread on that one, probably with datalogging and gps laptimes too :lol:

Back to your car though, what do you think needs improving about the aero?

[pablo]

I am just a bit concerned that the new evo air vents in the bonnet will might affect the air flow over the car and to the rear wing. I now that things in general can be improved by putting on more expensive suspension and better tyres. For us part of the fun is improving the car in small steps and not via the usual route.
The overall handling, balance and stability of the car is pretty good at the moment, (although it is set up more to suit Alan's driving style than mine). So imagine how much better it will be if we need to fit Toyo R888'S. As it is Alan can go through the craner curves at donny at over 100mph.

If it is of any use to you Pablo i have several moulds for bumper extensions maybe you could alter one to suit your needs

[pablo]

Cheers martin I will let Alan know as he is the one who does all the fabrications. I just say roughly what I want and somehow he makes it

How far do people go when it comes to sorting the handling and high speed stability of their cars.

When setting up our car i take into consideration what the air flow around / over the car could do.
We have recently bought a new bonnet for the car with large vents to get rid of hot air. Sitting down and thinking about it I believe that this could potentially have a negative effect on the handling of the car. As the hot air is sucked out of the top of the bonnet it will mix with cooler air this could affect the smooth air flow over the car, which in turn could affect the air flow to the rear wing.

Have you actually checked that the wing I currently getting good air? (Oil drop or wool tuft testing) Most cars have very poor airflow by the time you have passed the windsccreen. Top vent rads are generally not good for clean airflow, but it depends what you are starting with.
Doing an oil drop test on the wing before and after fitting the bonnet should tell if there is any real change in clean air flow.

Merry Xmas

The rear wing has made a big difference to the car. In a straight line the car is sublimely stable and cornering speeds are up. Also when we trim it out for road use the fuel economy has improved. We plan to do some testing of different parts in the new year.

Why don't you make lots of dimples on the bonnet and wings of your car like a golfball has so that you travel faster and maintain stability through the air.........
Why don't manufacturers actually do that on cars....just make bodies completely covered in dimples?? Works for Golfballs!! :idea:

were's my hammer :twisted:

i am so looking forward to doing this little project as i have got few ideas and designs
in my head on how/what to do.

The fuel economy and stability indicate that the rear win may now be a reattachment point for the airflow, improving the Cd. The old Toyota MR2s used to do a similar thing. It would be interesting to see the test results on the underside of the wing.
