Hi Joe, You will enjoy Blackhawk, it’s a great track. I raced the G 125 class, 410 lbs, over 35. I usually ran 20/25 gearing. I ended up with a 100 mph ± a MPH or two at the end of the straight. A good lap time is 1:14-1:15 in that class. The CIK class, 185 lbs, no age limit. Will run about 1:13 laps. I guessing they run around a 20/24 gear.
You may want to consider joining one of the clubs that will be helping at the race. Either CES or RVKC. If you join RVKC ($50.00) you will be eligible to win a toolbox at the drivers meeting on Sunday. RVKC members also do not have to pay to rent a transponder. RVKC will also be paying out money for one of the races on Sunday. Top RVKC member will win $125.00, second RVKC member will win $75.00 and a random RVKC finisher will win $50.00. The class will be announced at least two weeks before the race weekend. Check out their website http://www.rivervalleykartclub.com.
