what numbers are the flux 4.3s and twin pumps capable of with the big single?

 

low to mid 700's but it will be toasty

 

how bout with twins?

 

What is the lift pump set up???

I saw a truck dyno this weekend....dual cp3's and 1 walbro....walbro couldn't support it, fp hit 0....however, he dynoed 810hp and 1800tq (dynocom) at 3100rpm let off......64/14 and 100hp injectors ....there is some internal work done. He does spray water/meth too....gains 100hp with it too! 50/50 mix

that said and like you know Bean, theres a lot more left in your set up. How do you dyno? Load the turbo at all with the brakes? Ive seen that make a difference with a big single!

 

It has a Airdog feeding a SX pump and I run it at 70psi. I am thinking that the AD may be restricting the setup cause I would think the SX should be able to feed it better then that unless its just getting tired.

Those dynocoms are wacked, I have a very hard time seeing 800hp out of a 64mm turbo water or not. I have seen them throw down some wacked #'s on other trucks too like that.

I did load the brakes best I could, my throttle is very tricky if I get into it too quick it will fall flat on its face and smother out. Makes it hard to do a snap throttle dyno test. I think it jumps the rail pressure up to quick before the charger can react causing it to snuff out the charger with too much fuel before it has enough air to burn it. On the street I have to slowly get into the throttle so that it wont fall on its face, it will go from 30psi of boost to 0 if I get into too quick. like I said- NEEDS TUNING badly.
