Chase for a 10 second slip Finally after battling issue after issue for a year I got my 10 sec pass this past weekend. I finished my H/C swap about this time last year and two days after it floated a valve, busted the valve head off and spit metal in almost every cylinder. It ended up trashing a few pistons and both heads so I picked up a rotating assy from someone with a stock polished crank, scat rods and mahle pistons for a decent price. Took all that to the machine shop and had all new bearings put in and the short block put together.
After getting everything back from the machine shop including my new heads I got the motor back together and in the car by the end of that week and was putting break in miles on it the following week. As soon as I was able to I took it the track to see what she would do with a previous best time of 11.42 @ 120 with just exhaust and a 150 shot. Well as luck would have it I found the next weak part, my clutch master I guess couldn't keep up with the added power and 7k rpm shifts. I wasn't able to get one pass without missing a gear. I can't even remember the time but I do remember the mph was 131 so that was promising. So I gave up on that for the time being until I could get a new M/C.
Once again luck comes along and I end up losing 3rd gear completely in the transmission in the fall of last year so racing was done for the year. Well before the year was up I ended up purchasing a new adjustable master but still didn't have money for a rebuild. About a 2 months ago I finally saved up enough and bought all the parts for a rebuild/upgrade and attempted to do it myself and low and behold I can now rebuild a T56
So about a month ago the track opens and I go to get my slip. I don't have a 2 step in my car yet so I've gotta do some footwork to launch my car. I figured I could slip the clutch and still get a decent time, no. The best pass that evening was an 11.42 @ 131 so I know it has more in it but what did I need to do to get it there... Well this past weekend I go out again and try dumping the clutch like I used to and that does the trick! First pass on bottle is a 11.0 @ 128 launching at 5.5k, second pass I launch at 6k and boom! 10.98 @ 128 with a 1.6 60ft.
I think with a 2 step and a little more experimenting with tire pressure and launch rpm I can get it down even further but for the time being I'm extremely happy!
