I've had the spray on my duster for a couple of years now and haven't really used it other than some short tests. Until last night. Its an Eddy RPM plate system and I have jets for a 150 shot. Well, I was out on Woodward and this guy in a Chevelle kept trying to get me to race. It sounded fast, big block, solid cam, etc. Well I armed my system, opened the bottle (remote-its really cool) and we finally caught a light. Did I ever waste him. My duster is probably a 12.20 car on the motor (383). Actually a crap motor, 9.2:1 CAST pistons, crap heads, you get the picture. But man, when I nailed it she really screamed. Even the exhaust sound was different. I figure that with a 150 shot it should be capable of low 11's or maybe even high 10's. Can't wait until the next time that I have to "test" it. BTW, I have a bottle heater, purge, and remote bottle opener that all get armed from the same switch. It also sends a signal to my Mallory ignition box that automatically pulls 6 degrees of timing out. All from the driver's seat. Definitely an "E" ticket ride.
