I twisted an output shatf off if that's what you mean?
Pictures?

Yeah, I was asking about what got tore up.

So Im runnin 3.3's with the standard tnt and a stage 2 floor it cp3 with an a5k. So why are my numbers so much lower than yours. Im at 644 without too much tuning. JD said the rail looked like it was staying good under power so a bigger cp3 or duals dont sound like it. The cam doesnt add much if any HP and im movin enough air to clean it all up and the std tnt makes the most power before the springs would come into play. Any ideas. Congrats on the numbers by the way.

T,

What combination of tuning made the 644?

Remember that 2 pumps have the "potential" to provide twice the volume as a stock pump. Pressure is part of the equation and yes pressure is a measurement of restriction, but one cant measure rail pressure except as an average number.

Did you dyno with a speed limiter version?

I dont know John at floor it and JD threw it on there the other day. I had asked them to if they had the dyno out to throw mine on it since its sittin at the shop. Yes mine does have the speed limiter set at 200mph

Also on a side note John and JD were both pretty impressed with the top end power and said it felt like a 700 + truck.nI suppose I will find out all that info when IO go to pick up the truck in a week or so.

Don,

Malcolm put the new 4.4's in and we ran off to BD.
No tuning no playing with setup just put the Smarty about ....there....and rolled 783hp on BD's dyno!

I was pretty happy considering it was the first pull!
It'll make 850 no problem.

The truck knocks pretty hard (HARD!) until I open the throttle.....I am wondering if the extra "event" is screwing things up?

Any thoughts?

What did onetun put down at BD?

Idaho CTD

Rob (Onetun) did 863hp. Snapoff did 780 ish.
