i'm building a forged shortblock but staying 347ci with heads, cam etc (listed below). i am planning on puting around a 200 shot of nitrous and was wondering what kind of fuel system i need to support this. will a t-rex be enough or do i need something else? i was also wondering if i should step up from 28# injectors to 30#?

build a stand alone system. see the direct port post. that way you know you will have the fuel system to support 200 without a doubt.

What type of system are you going to run, wet, dry, dp. There are many factors in what type of fuel system you will need. Let us know and we can help ya out.

Depends on the cam and basically the whole package. I have a TR224 cam, few mods, using a Walbro 340 intank pump I run a 175 Wet shot, the AFR goes to high 10's on spray so I am not starving for fuel whatsoever. But, a bigger cam, some heads and etc...and try a 200..then I might be pushing the walbros limit. FWIW, I sprayed 200 200wet, stock bottom, used little timing, lots of 116 leaded race, and lots of added fuel to the WOT table, it was a dog, too many items against me on that one, even though, it still didnt run out of fuel.

Our car is heads/cam nitrous. We spray a 250 and we only have the racetronix pump intank, which is about the same as the walbro 340. So as long as it's wet and you have that fuel pump you should be fine to spray 200.
If that pump isn't enough try a boost-a-pump and that should definately do it. We make 600rwhp on the spray with just that pump.
