ok my truck is goin into the shop tomorow to have new, thicker head gaskets put in because of the crack in one of the ones on there now. Also a set of lt-1 fans, new posi and 4:10 gears as well. Last time on the dyno ir made 389rwhp. that was through a single flowmaster, only 7 lbs of boost and my trans was slipping in 2nd, 3rd and 4th. Now it has tru duals, 11 psi, and a built trans. Also we are goin to not leave it as rich as we did last time. So anyone got any guesses on what the bitch will pull??? I say about 450 rwhp.

 

I'll go with 424 HP.

 

I'll got out on a limb and say 425+ P.S. do we win anything for guessing correctly

 

i will go 420, tuning is going to get harder at 11psi i think. the gears will probably cancel out the fans.

450 would be kick ***.

now here is the question, can you dyno more than a stock 6.0 with a 150shot

 

Look out for LTNKLR01 he is a man on a mission with that Radix powered 4.8!!! Hey, lets put a smaller pulley on that thing!!!!

 

ill say 420

 

heh 420+

 

Parish: I dont know if i can make more power than you. especially after the turbo, but i know this much. After this trip to the shop i will be the fastest 4.8 in the land. period.

 

hell yea, that is untill i blow up my 6.0 and have to go back to the lowly 4.8

you do have that thing runing strong, 12.6 is amazing with a 4.8
