Sparks, sparks, sparks.......

Catch a Opel Calibra Touring Car, reduce the height, decrease springs to the max, put heavy downforce, and lots of fun.

I think this also works with the Corvette C5R.

Sheron · May 30, 2003

This happened yesterday when I was drifting with it.
You know for drift the springs have to be very soft. And when the car was over 200 lots of sparks came out the rear of the car (with no downforce). Then I rised downforce and the car was all the time touching the floor!!!

Hmm... sounds interesting. I'll have to try this tonight. BTW - Other than the Calibra, what cars does this trick work with? 787B? Astra Touring car?

Sheron · May 30, 2003

I think with racing cars that have "ground effect" tunnel below the rear bumper

under18carbon · May 30, 2003

Then the C5R should be able to pull it off, along with the 787B and a handful of race cars. Right....?

Quite a lot of the cars do this F1s are the best

A difuser you mean? like what hangs out the back of the Viper race car?

under18carbon · May 30, 2003

What are those 'difuser' or 'ground effect tunnels' used for? What are their functions. and how does it affect a race car? :confused:

Answers please!!!

👍 Agreed.

The idea is that with ground effects, the air passes more quickly under the car than over it - this means the air pressure over the car is higher than over it, producing downforce. Downforce produces grip.

Thanks Vat!

I knew it had something to do with downforce...

the vertical panels on the rear of the oreca viper and other race cars just keep it srtraight on the track. kind of like tail fins on an airplane, they keep it horizontal and stable

liquidyellow · May 30, 2003

I think it has something to do with separating the hot air from the engine, exhaust gases and the cooler air flowing over the upper wings of the car as well.
Apricot hill is good for loads of sparks if you ride the kerbs too especialy the big hairpin.

Jugend · May 30, 2003

The "shelf on the orecas back is where the air-flow from the venturi-tunnels exit. Found this on some site:

Glossary

18. Venturi: A narrow tunnel under the side pod, shaped like an inverted wing. As air enters and is forced through the narrow center,its speed increases, creating a low pressure area between the bottom of the car and the track. This creates a suction effect, which holds the car to the track.

19. Venturi Effect: Fluid speed increases when the fluid is forced through a narrow or restricted area. The increased speed results in a reduction in pressure. The underbody venturi is shaped to create a low pressure area between the road and chassis which creates downforce.

it also works with the toyota gt-one race, nothing much. there just sparks. :irked:

under18carbon · May 31, 2003

GTJugend: Hey, thanks for those. More detailed!

BTW- Where did you get the info?

DMX: Yeah, they're just sparks, but it's fun watching a 787B go full speed with sparks from behind like crazy. It's just beautiful :lol:

By the way Sheron i posted an X-Port file about a week ago which was a replay of a calibra sparking constantly around test course. Here it is again

eddieturner2002 · May 31, 2003

oooops i 4got to tell u the address.

eddieturner2002 · May 31, 2003

you can create sparks on any track with a car with a low rear bumper and wheelie settings

triple post :odd:

👍 Agreed 👍

the mercedes Touring Car (D2) also does it , lower the spring rate to the Extream left and the lowest ride hight possible

eddieturner2002 · Jun 1, 2003

any car with low bumpers and skirts that has a low ground clearence

mwoodski · Jun 1, 2003

look really cool in a wheelie though

Sheron · Jun 2, 2003

eddieturner2002: I don't have Sharksport, X-port or whatever thing to change the car. But I'll see your video.

Sparks, sparks, sparks.......
