Thought some of you would appreciate a recap of some major changes that have taken place in the wheel to wheel race series for 2001.
Skip has reduced the number of car classes from 7 down to 2. The fast class is GT1 and the slower class is GT2. For all practical purposes, there is only one car class, since only 1 or 2 drivers have indicated their intention to run in the slower GT2 class.
The GT1 class is similar to the Super Modified class from 2000, however, all cars must have a 3.07 rear axle ratio for 2001. All cars must be free of internal engine modifications and must run stock throttle bodies. Dyno tests of all cars will take place at three different events this year. Cars found to have excess horsepower will be penalized with extra weight at the rate of 7-1/2 pounds per extra horsepower. Minimum weight is 3,225 pounds with full fuel but no driver.
The GT1 car is essentially a gutted factory ACR with headers, lightweight flywheel and clutch, upgraded brakes, and aerodynamic pieces. All cars run on Hoosier tires.
Unless you an incredibly skillful driver, it takes about $30,000 to turn a stock GTS into a competitive GT1 car: Headers/exhaust $5,000; shocks/springs/bushings $6,000; aero front splitter/rear wing $4,000; front and rear brake upgrades $6,000; full roll cage/fire suppression/kill switch/5-point harnesses $6,000; other $3,000.
To further reduce the cost of being competitive, all qualifying and racing for the weekend must be done on the same set of tires. There are 2 qualifying and 2 race sessions each weekend.
The racing will be much more competitive this year, and virtually every driver will have a chance to win first place overall on any given day.
During the first race event at Willow Springs, numerous drivers failed to meet minimum weight requirements and had to add weight to their cars before qualifying and racing. One of the drivers had to carry an extra 150 pounds of weight because his car dyno'd at 20 extra ponies over what his teammate's stock motor did.
6 of us will be doing a dyno on our cars in Phoenix on February 22 to make sure we all fall within a reasonable baseline range for rear wheel horsepower. Obviously, headers/exhaust will effect rear wheel horsepower and Skip will establish a reasonable range within which he expects stock motors with headers to dyno. Skip will look at both peak RWHP and RWT as well as average RWHP and RWT throughout a range of 2500-5500 RPM.
If you are a Viper owner and have a completely stock motor with headers, K&N filters and smooth tubes, and a 3.07 rear gear, we would love to see any dyno results you may have. We need to see RWHP and RWT at 100 RPM increments. Please e-mail me your results.
