The race is less than two weeks away, so I will have very little time to dial it in. I’m going to run a stock 4/6 secondary, and a modified primary. I set the primary up years ago to run on my stock Invader, it has E ramps modified to Aaen spec and a red spring. It makes for a hard, high rpm launch and pulls hard all the way through. I’m starting with stock 440 Invader gears. The race is 500 feet.
