i used to do that, with my stocker. i had the vents capped with baby food lids. BUT when it came time to lay down the power, i pulled off the passenger side cap, took off the aircleaner, and attached a hose from the vent to the carb itself. was able to slam second pretty hard getting ONE tire to chirp. without the "supercharger" mod it would only chirp if you were turning, unlaoding some weight from the tire.
went to the track and was laying down consistent 19.4sec passes!!
had time to read EVERY SINGLE AD on the track wall, all the way down.
