All of this info is available on the forum in some fashion. Hopefully this thread will encourage you to come race. Remove some of the excuses. You might as well go all out.
First get the resources available:
The Block and Glenn's video.
THEN:
Get Good axles - Ditch THE BSA axles
For example: Glenn's grooved axles JewkesEngineering or MB4hire The new ones 91s are the bomb.
Get good wheels: Ditch the raw BSA wheels. Get the Pure Stockers...
Drill your holes with the block. Key to alignment
Quality Axles and Wheels are also key to alignment and raw BSA components are not going to make it sub 3.0 very easily...
Cant rears negative 2.5 using the supplied pin included with the block.
Bend DFW axle 3-4 degrees and use positive cant.
Adjust steer of DFW (Dominant Front Wheel)
Here are the steers for two Pure Stockers over 45"
Rear of car starts 45" FROM finish line.
CoalCar 3/8" COM
Steer 2 15/16"
ClearWater 7/8" COM
Steer 2 11/16"
COM. Go for 3/4 " This COM will go sub 3.0 no problem!!!
Use a tungsten DISC or Cubes. At least 3.5 ounces. More better. Keep it all near and around the rear axle. (Dont add weight to the front or middle of the car. Keep it all together.
Make a test car to get the COM right and then build the final car...
Use Hobe-Lube
No need to go over 3/8" in thickness or less than 1/4" in thickness of the body.
Gap wheels at 1/32 inch.
For front and rear axle heights these are posted on the forum...
5/32" on rears
4/32" on raised wheel
3/32" on DFW
Round down the front of car in front of the axle... to create a gentle sloped nose...
Dont copy coalcar!!! Keep the car a plank for better everything....
Better staging, better car...
No holes in car unless covered for wind reasons including bottom of car..
Narrow the front of the car 1/16" on the DFW side. Have fun and post lots of questions to the board.
UPDATES:
Make sure your wheels are clean. In particular make sure there is no graphite on the tread surface of the rear wheels.
Keep your added weight low...
Meaning if you use cubes keep them in the body of the car and drill the axle holes half way up the car...
If you are using a disc. Drop the disc so that it is flush with the top of the car OR center the disc with regards to the axle. Do not leave it high.
