Did well w/ my Mach at the track but I'm now in a whole new ball game. Lost over 100 hp while going from a stick to an auto. I'm familiar with how to make a car go faster but need a little feedback to decrease the chance of putting one gear in then wanting the other. In a nutshell, I need to know if 4.30s are too much with stock tire height. Paladinmicro gear calculator puts 3rd gear 6k rpm @ 103 mph, 6200 is 107. The eventual goal for the car is a 12.99 n/a. I guess the two main questions to be answered is with the auto 2V what rpm should I be crossing the traps (tach redline w/ stock gear is 5800) and what mph it generally takes to crack into the 12s. Thanks for any help.

what are the total mods? my old gt ran a 13.2 with full bolt ons minus headers and a 4k stall, on dr's and it only trapped 102. if you get a stalled auto car to trap 107 then you're 12's.

also, 4.30's are gonna be a good thing for what you want, dont plan on good mileage on the highway tho. but if you cam the car and with 4.30's then put in a stall and a spiral ring retainer in the trans you can rev to 6500 safely and will be running some good times for a n/a auto 2valve.

No mods other than CAI and flows, which aren't mods in my book. Just getting started with this one. Gears were going to be my initial change then see how much mods change the stats from there on. It's not my DD but I can't take much more of the stock 3.27 rearend lag when I want to take her for a spin. I was thinking the same around 107 for the 12. Appreciate the reply.

Just read your edit. That's what I wanted to hear.
