A friend of mine has a 2010 z71 excab, and is wondering what he will run. He ran 13.63@9x.x mph with 400rwhp and 428 rwtq with a mp112 @ 6lbs ar headers and a tune. That run he never shifted out of 4wd. Now he is running meth with 10 lbs of boost (453 whp/ 540 wtq) and a yank sc 3000. It dead hooks on the street, so beware if you live around the nw Houston area. What do y'all think he should be running now?

 

mid 12's.

 

what does it weigh?

 

That's a lot of beating on for a brand new truck under warranty.....but to each his/her own.

 

I would think mid 12's worst case.
I think around 5600 lbs
He hauls a lot of trailers, guess he figured he needed the extra power

 

Truck sounds nasty, is it a 5.3 or 6.2?

 

+2...

 

Its a 6.2.
