I'll be cleaning up the shutdown, on Saturday, for a race on Sunday, so I'm hoping with glue not all contaminated with tire rubber, it will stop faster in the future.Īnyway, with the realization that the German rubber is the way to go, I'm confident we'll see a sub 1 second pass, with a dragster powered by an all vintage motor.Īnd I think there's a good chance it will be on my regular/modern 16V power.1.Tungsten weights are used in pinewood derby car with their excellent properties to make pinewood derby car go faster on the track. On the last pass, at 24V, the car went 1.201, running perfectly smooth.Īlong with not biting too hard on the launch, and the pass, it also didn't bite hard in my shutdown, and it used up almost all of the 44 ft, so we decided to call it quits. With the slow motor, we just turned the voltage up and up, with car getting faster on every pass. While I could spot some arcing from my ideal vantage point, the car ran perfectly smooth. Once Alan put his Hustings car, with the German rubber, that all changed. Sort of like a series of reverse wheelies. It was more entertaining as it would launch both rear tires off the track, and slap them back down, at the same time. Once they made the pass and were subjected to any light film of glue on the track, and morseo, the shutdown glue, they were useless for all subsequent passes, that night, hopping hopelessly.Īlan's car with the Protracks was even more comical than any of Mark's. 300, and it was the first pass he tried that night, with the tires sitting on the car, to dry out out for a week or 2. When he made a 1.08 pass a few weeks later, it was only accomplished because the Protrack tires were narrowed to. They were that fast because the motor is a monster. None of Mark's early low 1.1 passes were anything near smooth. The dealer, a few blocks from my raceway, had to sell it me under another name, as he would be breaking some sort of policy (or law?) selling it to me as Mike Swiss, or Chicagoland Raceway. It's painted with a Sherwin Williams 2 part epoxy, that sells for $190 + for the the 1 gallon kit. The Protracks just are not the way to go on my track, with this style of car. After watching these vintage cars go down the track, periodically, in the last year, I agree with Isaac S's post #411.
