I baselined my car at a local 1/8th mile..It ran an 11 sec flat..cant remember the mph..backed it up twice. All I did was take out the air filter, left about 4k and powershifted 2nd n 3rd about 6k. In my opinion, not bad for the little car. I now have cai and plan on doing the underdrive pulley and exhaust and going back. It should pick up quite a bit but w/o a way to tune these cars I dont see it getting in the 9s w/0 further mods and extensive weight reduction
