I am about to order a ZEX efi 125hp nitrous kit for my car. i currently run 13.6 at 102 with a 1.97 60'. I would like to get an idea of what kind improvment i could expect at the track. any one out there who has experience with NOS, if you could let me know what your times were with and without NOS and how much NOS was used to get that improvement that would be great.
