justa6;
Yes I have run Hyper pistons before..and they have not held up as well as forged. There is a reason that most professional engine builders use forged pistons...
As for times, in street trim (at the Texas Motorplex in Ennis) I go to the Friday night Street Heat races, which are rung whatcha brung street legal races, I run in the high 10's to lo 11's. When I change over to slicks and beat the car a bit harder I can get to the lo 10's. The absolute best I have ever run was a 9.97, with slicks and 5.36 gears..and twisted an axle doing so! You can granny the car and run mid 11's all day...
I've also had the pleasure of running at Hallet Raceway a few times and put in respectable lap times, although it meant looking over the doors so that I could see where the car was actually going quite often!
