I was going to post a question about this yeaterday but since u did, Ill post my questions here as well.
To start with your questions. Ive seen people running 13.5's or better or worse depending on track conditions and driver skill. Of coure weight of the vehicle also is a determinate of course. The kit comes with everything plus some things that other kits dont. Be sure to get the sn-95 adapter elbow, I dont think they include that for our cars.
My question is. Is it better to go with the street heat or track heat setup. Because one has a bigger cam, which would be better. Plus, do these cams(stage 1 or 2) need a tune of any sort to get them to idle right
