Re: Air vs Electric stops
 

Have a #1 stop under the carb and a super sucker back to back runs with and without the stop same ET did this on gas and alky Everyone told me the stop wood slow the car a tenth when running it wide open.
Guess it has to do with your set up. This was done with a 1050 cfm carb one is a ruppert carb and the other is a devince carb

Re: Air vs Electric stops
 

I like under the carb #1 stop. I ran electric on my 8.90 172 sc dragster and never had a problem. If you use the stop in low gear I would use an air on air off so you can control traction problems. If you are on the stop in high gear electric is fine. I was on the stop at .050 and shifted at .5 into the run and went wide open at about 2.00 seconds. If your turning 4000rpm on the stop and your in high gear your not going to have any traction problems. I was running 1.70 60 fts so I was only about 80-90 feet out when it went wide open.
