You guys are using an ATV motor. Don't you think that might be a little too much torque. We've always had great succes with motorcycle motors.

The torque is actually a good thing for us. However you are certingly correct about the uneven intake flow into the engine due to the single cylinder.



I'm not a supporter of the single cylinder, the decision to use a single was made last year. we put some bolt ons and stuff hoping to get more power. The effects of the large changes in pressure waves can be compensated by using a huge intake chamber/runner volume at the sacrafice of throttle response.



Next year they will move back to a 500 cc 4, or maybe some sort of V-twin.

oh yeah, our car ended up costing around $18000. that's $3000 less than our car last year. and we weight 30 lbs less than last year. i'm happy about that.



today we are going to tune the suspension on a skidpad.

are those aluminum MMC brake discs?



large crush zone. they dont exactly define what the crush zone has to be made from, we we made it out of 3/8" x 0.035 wall chromoly tubing. haha, it's light. we're going experiments to see how much "crash" energy they absorb.

we use some sort of aluminum foam infront of the brace. The tubes are thin wall aluminum.



Yes they are MMC aluminum brake rotors, the trade name is Duralcan, we are sponsored heavily by alcan. Before they changed the rules for the rear roll bar being made out of the heavy ass mild steel our car was 315 lbs 7000 series aluminum.
