I have followed the safety-related threads here with interest. When I had my race car, I spent a significant portion of my build budget on safety items (although in those days "Hans" was known only...

Remember the old fuel-injected CanAm cars? The intake "trumpets" were two or three different lengths. This was done to spread the torque peak over a wider operating range. The peak would have been...

The best way that I know of

If you think about it, we don't (or can't) really drive that way. ...

What if I showed up with, say, an SCCA GT3 or 4 tube frame car with coilovers, big brakes, and slicks, and bolted some lead to the floor. Would I race against showroom stock Honda Accords?
