Racing Corvette test video [wicked!]

Hi, things takes time but finally the Corvette is out on its tires.

http://www.speedlab.se

There is a lot more work to do, I am designing a new rear wing profiles that is to be finisched in a coupple weeks. Then more advanced testings is to be done. Car weight is 2100p.

Now we have been out on the track test driving the car. I must say that we are very pleased so far. We increased the front wheel rate to prevent the splitter from hitting the ground. We need to reduce the expansion of the rear diffussor with 2 "to raise the downforce effect. Greater expansion reductions resulted in less downforce. The rear wing was mounted to dramatically increase rear downforce. At 110 mph, we had about 600p over the rear axle.
Here is the starting diffusser level.

Here's how it looks after adjustment.


The steering was good feeling when all the downforce came with, and the manual concept car is working well.
We were wondering how the almost zero consolidated front end geometry would work, 1 SAI dgr, 2 dgr caster and almost no scrub. But together with the manual steering so the drivers thought that the feeling in the steering wheel became even better and cleaner.


We are now starting to get a better picture of how the spring system must be designed and we will probably use a third vertical system that has about 1/2" clearance before it stops kompression from downforce. In this way we can go right soft suspension (more front roll stiffness) at low speed and get good acc grip out of the curves.

That is quite the machine you have built

What does your power to weight ratio look like? Based on the sound coming from that beast in the video, it sounds like you've cracked the 4 pound/hp figure

That's got to be one of the baddest Vettes I've seen in years.

SICK!

Enjoyed the video.

I follows the rules to be able to race in a coupple of cup:s.
The maximum width is 2 meters or 78,7". The outside of both front and rear axle tires are 78,4" which means that the front track is 1" wider since the front tires are 1" narrower. Height is 39,37".

The car weights in at 2090p and I dont have any Hp figure, but an estimate at 550-600hp. So with an average figure we got 3,63 p per Hp.

The sound of the engine is very much due to my design of the exhaust sytem which is a 7-Y. Excuse me for the term 7-Y, but it is in principal a single outlet 3-Y system which makes for 7 Y:s. The idea was to create a system where all pulsing will even each other out, in order to reduce sound without a restrictive muffler. A very open system does not build heat in the primaries making life much better for the driver while at the same time pass the Db check. The tuning of the pipes will sort of sound like a flat crank o 180:s.

Are you related to Zora Duntov? You definitely talk the talk and walk the walk. Impressive.

Now we have tested the car a bit more and everything seems to work well so far. There will be no more tests this year for winter makes itself felt in Sweden now, but we have a good picture of what needs to be taken care of during the winter.
The aerodynamics look good, both for distribution and power. As you can see on previous images we have placed the wing very fare back, actually behind the car, which seems to help the diffusser good. In any case, so we can have a greater diffusser expansion with the wing in this possition. We have currently about 1700p at 120 mph, distributed fairly equal weight distribution that is 56% rear. It might seem a lot but the measurement is made over the suspension system and may contain errors. I'm talking mostly about aero and it is because that is what I was most uncertain if I'll manage to get to the good. But the car has of course many other sides worth mentioning, but it takes more out of racing driving for an opinion. Now I hope for the team to have a successful racing 2010th

Thanks!

I have been disabled by writing what is happening, so here is a little update.
I tested out a new wing in my small wind tunnel I built. It has a profile that is quite aggressive, the Swedish tracks that are not so fast. It hangs in the so-called "swan neck "
and is located at 100% of its Corda behind the car.


The diffusser.

Front.

The car has good downforce, so an extra vertical spring is needed.

In fact the load become so heavy that the wheel broke.


Therefore, I have now designed my own wheels, which I hope will be both stronger and lighter. Here I am holding the basic watercut centre, waiting for final cnc machining.

The wheel has no recess in its center to get a better strenght over the entire stretch out to both sides of the rim trails.
