If you read the post that Barry made, you'll notice that he's running a vertical cut in the negative brush, not horizontal. That's what I've been running and have been happy with the results. I'm going to try a horizontal cut this weekend and see if it makes a difference.
thanks for the help.. I was wonder what made you 19t so frickin fast.. I have been using puntam greens with good success.. tgheyre heavy on the comm but yank major torque.. I have been able to gear as low a 5.9! with my chamelon.
Hope things are going ok matt.. norcal has tons of racing we;ll save you some 4 whnen you get back
At the Reedy Race we were gearing the quad's at 5.75. with good sucess. I tried to go balls out on the last qualifier and geared all the way to 5.5 because I was getting so much torque. Didn't get a chance to see what it really would have done through a full run. I got a bit of grit stuck between the comm and the brush and cut a nice groove in the comm about 2 minutes in. But it still didn't burn the brushes. It did feel a little soft on the bottom end. Those motors like to be geared through the roof on big tracks. Even on a little postage stamp track I ran a couple weeks ago and last week with no more than 40 to 45 foot straight I was @ a 7.0.
Long! If I had to guess I'd say it's around 85-100 feet. Not the longest I've run on but you head into a high speed sweeper after the straight so you're on power a long time. Most guys were topping out 3/4 of the way down and having to let off a little going into the sweeper then back on it once the car settled into the turn.
A 200 foot straight for electrics!! I ran on a parkinglot track with 150 foot straight and that was just too much. The problem was they were also making the infiled tight and technical along with the long straight. If you geared right for the straight you'd loose a lot in the indield. If you're right for the infield, you're topping out less than half way down the straight. It wasn't bad for a low turn modified but for 19 turn it was tough. Stock was just slow. There were more than a couple fried stock motors on that track.
