Nitrous Oxide - Considering options for moving up the ladder (to a bigger pill)

I'm running a TNT f2 kit on my 422 now. 500rwhp or so on motor alone. It's jetted at 100hp, I haven't had a complete dyno since the install, so I'm not sure what actuall rwhp will be.

So assume I'm crazy, and want to jet the kit to the kit max pill size of 250.

What would I need to upgrade? I know fuel pump (give me some recomendations and reasons), I figure injectors (currently having injectors that are 36 lb/hr at 43 psi which means on my 60 psi fuel system they will be rated at around 41 - 41 lbs/hr.)

What else? custom fuel rails?

Thanks...

make sure your rails flow evenly on both sides. and you may need two aftermarket fuel pumps. like perhaps 2 Walbro 304's with one set to activate under vacuum (dont know if/how that would work...I'd talk to Jayson, or Nick at ARE). injectors are fine and your motor should handle it. Your transmission wont last with out CAREFULL use, same with your rear. Also, if you have a converter that flashes to about 3500 currently NA, it'll flash to 4500 EASY on that amount of juice.

Thanks Underdog,

I'm already running a cf driveshaft and a KTRE rear, so the tranny is probably my weak link.

The stall converter is 2800 rpm, so pretty low.

Any of the rest of you guys running a larger shot on a stroker motor?
