Well, finally got the 428 Fairmont out to the track this year. I normally run my slicks (14x32)tubeless, as I think having minor slow air leaks thru the sidewalls an acceptable trade off for eliminating 20 lbs of natural rubber racing tubes. My tires used to lose only 1/2-1 lb per day when tubeless. Anyway, Last year, i slick got a small cut in the tread area, I had a patch put in, but I suppose due to the flexible nature of a slick, it don`t stay on very well. Since $800.00 (CDN) is out of the budget at this time, for new slicks, I dragged out the M/T drag tubes, & had them installed in both sides.Now the tires don`t lose any air, which is great, but I`m curious how much that extra 20 lbs of rotating weight is slowing me down. Anybody ever done a back to back comparision? I was about a tenth & a half & 2 MPH off my best numbers last year, but I also had a new belt driven water pump on the engine, plus it was fairly humid on Sunday.

This was discussed in another post about Bogart wheels. Alex had some thoughts about rotating mass and unsprung weight. I think the number thrown out was .05 per 10 lbs, but it would be best to search for the postings.

SEAL UP THE TIRES WITH DISH WASHING SOAP PRIOR TO MOUNTING TO STOP SEAPAGE. No tubes ever if you want good 60 foot times.

your right rory, a patch will not stick to the inside of a slick. however i have heard good reports about the use of a patch/plug.
maybe someone can help us here. normally all your leakage is through the sidewalls. i soaped up my m/t slicks real good and they wont leak over a couple of lbs in a week.

Alex, I HAD to put tubes in. One tire was going totally flat overnight, even if I put 20 psi in. You could hear it hissing out. It has a cut in the tread area, minor sidewall seepage I have lived with for years. Actually, my 60 fts wern`t too bad with the tubes,a 1.38, & 2 1.39`s. The best it has ever gone with these same slicks tubeless was 1.37. But I was more concerned about in high gear, thats where the car was slower. Right now, I have a new water pump hooked up to the crank, normally I use an electric water pump drive. So it could be a bit of each.

Dish washing soap will not fix cuts or punctures, that's for sure.
