Default which stage two nasty kit?

I am about to purchase one of their stage two fuel kits and am wondering which one would be best for my single turbo pump gas setup shooting for 650 rwhp. I like the racetronix plug n play ones , but was wondering if their single 340 would be good enough or moving up to their new dual 255 would be better or would it be overkill for only 650 rwhp and save a little money? Thanks

I'm only shooting for 600rwhp or more, and i'm going with the double pumper just to be safe. Mine is getting put together right now. It seems that once you get around 550rwhp fuel pressure starts dropping up top. A BAP would help a little, but you may as well do it right the first time.

Fwiw, I believe the HP ratings on the Nasty setups are based off a N/A car. The fuel requirements for a FI car are slightly higher since you're dealing with boost and a richer A/F ratio.

The only part i'm currently stumped on is to run the -6an feed/stock return, or -8an feed/-6an return. Decisions decisions.....

They are both the same pump. I went with the stage II & single + BAP. I haven't run it yet but it appears some people are having trouble getting much HP with FI on the single pumps.
I suggest the double pump, I will probably going that way but I am going to give this set up a try.

FI takes MUCH more fuel. Those ratings are for N/A apps. One pump isnt going to do it. One pump dies out at around 550 or so.

340 is the series or part# of the pump. There are different versions of the 340 pump for specific applications. 255 refers to the amount of flow it is rated for.

Ended up ordering their stage three kit with double pumpers might as well do it right the first time. Does anyone know what comes in the speed inc race fuel system? I think Nasty has the best price for a complete fuel system right?

As everyone has suggested the dual will be what you will need even if you could get that kinda power out of one pump it would be at it very edge. Yes the rec HP ratings are for NA turbo and boost require alot more fuel. Good choice
