first time running 12's
 
i hit a 12.50 at 108mph i was just woundering isnt my et really low??
i thought it should be around 110 for a 12.50. what can i do to get my et speeds faster? i always lose when i hit 3rd gear (A4)

i have cam, ls6 intake, full exhaust.
thinking about adding 3.73 gears but i dont want to lose what little top end power i have.

tuning? i'd say low mph for your modifications, but if you hook really well then 108mph is about right for a 12.50. also weather conditions and elevation?

i hooked pretty god. 1.7 60 foot. it has a tune but i need to redo it. i have different heads (from mti to stock :( ) i live in sunny south fla. it was very hot and wet that night. rained all day but cleared up just in time for the races.

What size cam is it?

You won't lose top end power, you will gan it with 373's. You will lose a little top speed though, but how often do you drive over 140mph lol. If you really want to wake your car up you should get a pair of AFR heads.

Also since you have a bigger cam you should look into getting a bigger throttle body, like a 78mm or 80mm.
