I thought there was a rule about bumping topics older than 30 days...

I don't come on here much anymore because all my time is taken up by this car so I haven't had time to update it in a while. Instead of starting a new topic I figured I would continue an old one. I'm pretty sure I can add to my own existing topic. A few people wanted to see some pictures of the car...now chill already.

I'm not against you rubber, i personaly thing that bumping topics rule is a joke, that's why we have +100 k posts in the forum, i dont see why players sometimes bump 3 or more old topics and nothing happen, but some guys bump one and get 15% warn on forum, this justice is out of control.

I think bumping has its place. If I thought I went out of bounds here I wouldn't have done it. I just figured it was my topic so I could do whatever with it. I thought the bumping rule was in place to keep people from bumping year-old topics just to say "nice mod" or something like that. But thanks for understanding.

Here is the car on its wheels as of 2 days ago. We hope to have it driving in a couple of days. Competition is a month away and we are still having engine problems. Right now it looks like I'm going to be one of the drivers.

For those that are curious, drive train is a CVT (continuously variable transmission), same as a snowmobile. The CVT is hooked to a chain which drives a sprocket. Wheels are 21.5 inch Hoosier slicks.

The only thing we haven't designed/made on this car are: the engine, bearings, wheels, tires, steering wheel, and chain.

Some of you may have noticed I haven't been on the server so much lately. That's because this is taking 120+ hours a week of my time.

are you having the camber tuned to average turn body roll? Or is your frame super rigit and not need much camber?

[Rockey]

This looks boss!

What's the average speed these things travel at? The driver in the video you posted seemed to be really hauling ass on some parts.

We have roughly 1.5 degrees of camber change over 3 degrees of body roll. We aren't expecting to get more than 2.5 degrees of body roll around a 1.5G turn (can't get more than 1.5G with the tires we have). Caster is about -6 degrees. Toe hasn't been adjusted yet. We only have 1 inch of jounce and 1 inch of rebound in suspension travel.

Nate, the average speed is about 50mph on the course. It is a lot of accelerating and decelerating. The fastest he achieved on the track was probably 80mph. As one of the requirements of the competition, all the engine air must be restricted through a 20mm restrictor plate. This basically dummies down the engine by 40%. Without the restrictor, our car would go 140mph+.
