Downforce Required

[Guest Turboz]

Hi there having just heared about the guy with the nissan turbo engine flipping his zero at cadwell going 140mph+ i guess due to excessive speed as the front end lifted on the straight. I was worried the i could have the same problem. Has anyone made any good looking atempts at downforce on a zero, splitter or wing ?

I knew seven type cars had bad aero but this is very surprising! Link to anything about the incident?

[speedtripledan]

Who was that then? And more to the point were they ok?

Canard wings will be required to keep the nose on the ground or?

Lower the front lift the rear

If your doing track days at that sort of speed a splitter might be in order

Hi Turboz. Where did the info come from?

Had mine at 120+ many times. No way would I like to go any faster than that.

I know the Zero are a lot more pro built but the robin! Never mind a laser, I don't even think they used a tape measure half the time.

i think the motto back in the day was " if it looks right, it's close enough.

think we need a little more detail of the accident and possible causes before strapping wings onto a Zero. Might just need the suspension altering, as sapperhall suggests.

doing 140mph on such a small twisty bumpy track you is begging for trouble

done a few track days there on bikes its a scary track

Having driven Cadwell this frightens the crap out of me , I will take a guess that the car was fitted with an enormous REAR wing and it got similar to the Mercs at Le Mans a few years ago ,seven type cars are about as aerodynamic as a brick ,sticking a fing big t tray on the back is lunacy , I 'll shut up now or many more bad words may come out mick

I'd be more worried about my body panels coming off or my windscreen flopping at that speed.....however I may need to consider the aero effects of my car after the engine swap...

Saying that, the Caterham 620R quotes a top speed of 155mph limited I believe. It would be good to see any aero work done on that and what happens near the top speeds...

Can't find any mention of this on the internet anywhere, which seems odd in these days of everybody having a smartphone or video camera and posting just about every little thing that happens on youtube.

 

Mind you, the story of the day I fell off my Raleigh Grifter and grazed my knee while doing 150mph down the prom at Blackpool, one handed, eating a candy floss and wearing a kiss me quick hat never got onto the internet until just now!

Every thing except the hat is plausable -- no probably very likely.

I heared ths from the large chap at javelin trackdays it was on the back straight after the dip just before the braking zone. The car was totaled he was was taken to hospital and escaped with just a broken arm and lots of cuts and bruises. I'm sure gbs will know more I'm heading there tomorrow anyway.

Probably the fastest part of Cadwell ,back inthe day I saw 6500 rpm in a fornula ford on the highest gearing we had around 145 mph , that straight aint very long !! mick

Didnt zoom zoom put a Nissan turbo in his zero?
