Got out this weekend with a stop watch. I only had time to do one run each way under similar conditions. Here's the details TQC 1982 Engine mod's stock boost 11.2 seconds 15 psi 10.2 seconds Averaged from two way down to single number. Not particularly quick, mostly due to lots of lag. Seems like some other bone stock cars did better than 11.2. Makes we wonder why. paul timmerman
