Not just to pop you bubble but 3.8 is not that fast. If you want some power from that 3.8 It will need to be Supercharged to get into the 13's That always means the time in a 1/4 Mile when the say 10's 11's
I would say you are in the 15's right now maybe even 16's If you need help just post it on this site it is the best one!!!
