Seems to me that the 130 or the 150 club is a lot harder than unlimited go-fast runs on the long courses. If somebody made a "W" rated snowtire, that is what I would use on the driven wheels, but that ain't in the cards.
I expect there's a few people who will dispute the difficulty of the 130 club.
Tires that "damage" the course are disallowed, your road tires will do just fine as long as they havwe the right rating .....you could do worse than get someone other than a grunt to balance the wheels and tires.
I'm looking for salt drivers who can advise me whether narrow or wide DRIVEN wheels (in their expeience) can make a difference in terminal velocity over a one-mile measured course.
I am SO pumped to do this next year. I wanted to do Speedweek this year, but life got in the way. I think World of Speed is in my bucket list for 2012.
The advice you will get here about tire width will trend to narrow, but there will be some persistant advocates for the wider rubber. Likely you're under 400hp, with little pedalling you shouldn't have any trouble as long as you do your sums right and have the right final drive to reach the speed you're after.
You are shooting for 130, not outright speed, there are calculators here that will help you get a rough idea of how you will get there but with so many variables the results may be gibberish.
1./ Calculate your rear tire circumference.
2./ Calculate top gear ratio( is it 1:1 or an O.D box)
3./ Calculate the distance the car travels for each revolution of the motor( you'll need the reciprocal of your diff ratio)
Now, the number of revs per minute will tell you how far the car moves in a minute, multiply by 60 will give you an hour... When you do the little sum to work out the distance time relationship you can calculate mph per 1000rpm's
I could have given you a formula there , but I would have expressed it in metric measurements (like um because it's waaaaaay easier) and converted back to MPH.......
I'm sure you can work it out.
Bottom line is tire slip ( in the relationship between V and rpm)and terminal vel. aren't issues that are going to trouble you too much in the 130 club...Tire slip will increase as you go faster due to the increased resistance to your forward movement, and that's where ballast becomes an issue.
Welcome to the game.
