rod ram you will defently get there you just have to tune and tune. adjust fueling settings and turbos. its a huge number to beat for a vp truck on straight fuel. i think that putting a bigger injector in that would get you over 600 and then you loose your driving factor becausr of tons of smoke would be kinda pointless. maybe adjusting you turbos or playing with your boxes. and the dyno does make a difference without a doubt. i hope you break it, you could always look at switchin out that top turbo for a htt turbo.it would move more air.like what idaho said you cant just adjust on thing on your turbo set up they have to be balanced, a larger front and a free'r flowing exhaust side would help alot.

it is expensive but it would still daily drive if you did like a 62htt the turbo creates vacuum to force one to spool. i have a k31 which is smaller than what you have,it spools really good. an s400 and a cam now for you will spool good.I might look at getting a larger top turbo

true, but I think my smaller S300 is part of what makes my truck so streetable. I know I can get 2 or 3 more hp by messing with the twins and boxes. I have only messed with the twins once. I ran the Smarty on #9 and the TST on 9 for my best run. I'm wondering if the smarty #1 setting with all the timming might help, but not sure if it will fuel hard enough. I think my air supply to the motor isn't off by much, full fueling, my egt's only get to 1300-1350.

i ran a 64/14 on top and i could tow with it and it did fine. it is pretty streetable, when you have two charger working together the lower turbo starts to spin and move air so the upper( your s300 ) can put air intothe engine.(i dont mean to teach) just explaining my reasoning. that air in between the two pushes the upper or makes a vacuum and forces the upper to spool. the engine sucks in the air. like a vacuum effect, you could run a 62 on top and it would be very streetable. i daily drive mine but i have a k31. you have a s400 a bit laggier but not a ton. it would do very good, especially since you have a cam. is the s300 switchable with a htt 62. or even 64. ron has ran this combonation and we wont daily drive andy things but a k31. and for dynos he uses a s400.

yes, I can change it out. I might try that sometime down the road.

I just bolted my truck together and made a pull. I pulled a 670hp on the first pull. Sticks this big are smokey daily drivers. To pull 800+ your gonna need nos. I haven't seen to many vp truck that pull over 700. Nathan wright pull 700 using mach 7's and a low 12 second pass.
