Parish-let us know. Thats a beast for sure!!!!!!! Good luck.

 

i stand corrected sorry parish lol looked at my calc. and yes your right about the 32" tires they help alot. later

 

I've not visited the truck forum in ages, what are you doing with a 4.8 in your truck?

 

P-a-i-n

 

i blew up the 6.0 with a nitrous misshap and am waiting on a built 408. thought playing with the 4.8 would be fun.

the saturday in 2weeks is no good for the dyno so we are going next week!! , i need to get ready.

 

i say 545 rwhp and 529 rwt. Damb I better hurry up and get my **** together or i am going to have to change my sig.

 

i will be expecting a long vid parish

 

you need just a touch shorter tire since you should only have to run it to 6200 with that 4.8. i'm predicting:

435/460
455/480
585/590

 

i will call them and ask on the 150mph thing. i will be running the 4.8 up to 6000rpm max, it just stops pulling by then. 3rd would be better if i can do it.

 

would like to see the video in 2 parts on each run,
one on the gauges and one on the dyno screen,
my guess

pumped gas 12 psi 93oct
440 HP 455 tq

race fuel 20 psi 118oct
550+ HP 550+ tq

too bad your not running air plane fuel too the Oct on that is 112
