View Full Version : What is a good fuel pump for nitrous?

02-25-2003, 12:46 AM
Well, I am going to run 200 shot NX MAF kit, and I am wondering, what is a good fuel pump to use. I have a walbro in my hands right now but I am thinking of installing a T-rex inline pump instead, any thoughts or advice?

Which one of these will need tuning the PCM and which one will not?

And, is one of these going to be enough with my setup (look at sig.)?

My 346 put down 430 rwhp N/A and I am putting in a Walbro 340 for the bottle. I will let you know how it works <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> I've been told by several people/shops your better off changing the intank pump vs. putting an inline pump on.

since you have a 98' get the racetronix pump kit. it is a complete bolt in kit comes with everything you need and supports 600rwhp or 700rwhp with the voltage booster. Also very detailed instructions with color photos.

A.R.E. carrys them.

Since you are also stroked with heads and cam, I would at least go with a racetronix pump.

The better solution would be to run a seperate fuel system for the nitrous setup. Add a 1 or 2 gallon fuel cell with an inline pump and that should support a 200hp shot nicely.

Also keep in mind that a 200hp wet shot can lead to problems down the road. This includes extra stress on the crank and rods because of uneven distribution of the nitrous. Plus, puddling in the intake tends to happen more often with a wet shot over 150hp.

I will call ARE and see how much they sell them for. It sounds way better than what i was going to do!
