I have the same problem. I have a vacuum canister but can only hit the brakes twice before the vacuum is 0. This is what I do
- Pull up to the water in OD and spin the tires in the water to get them coated.
- Pull up put the car in N, let off the brake and rev the car up a couple times to build vacuum.
- When the official signals you, hit the brake and hold, put the car in first, and STOMP the pedal to burn out and shift through the gears(1-3) and letting off the brake and gas slowly as you pull up.
- Pull up put the car in N rev up to build vacuum.
- Put the car in 1st and creep to the line. I lose vacuum by creeping to the line with brake, gas, brake, gas, but the car leaves the best from 1200-1500 or where the suspension is relaxed. Torquing it up makes it worst like taking it to 2000+RPMs
I do this all the time if you have seen how I run my car. I had a shitty night last night, I couldn’t hook for shit and my fuel pressure dropped from 9 to 5lbs. My best was a 7.10@97 with a 1.52 60ft.
