Thread: To HP or not to HP...that is the question.

Get the HP, they cost the same. Stock FPR will be fine with the stronger pump.

the pump creates the flow. not any pressure. thats what the fpr is for. changing the pump shouldnt effect the pressure. (unless its some enormous pump) if you plan on staying under 450hp then the 255 should be fine. if you ever plan to run more then just get the HP

I never knew about a HP model lol. I've been using the 190 for years now with no problems, but plan on going up to the 255, and jumping up to a 150 shot on the nitrous. Where are you guys buying them now? I think when I got mine, there was a forum member/sponsor selling them.

GSS341? Is that the correct part number for the 255hp?

Lol nothing? I'm just wanting to make sure I order the right part, and can't get any confirmation? I assume that since I already have a walbro pump setup in the car, I only need the new pump, and not install kit.

From what I can tell the GSS341 is a Walbro 255 lb/hr High Pressure pump. So you're good there. They have a few models though, with slightly different inlet/outlet placements to work better with one car versus another. I think you should be fine with that part number Aaron. To be sure though, someone else will have to chime in or you could do some more research.

If you have the pump in the car, then you should only need the pump and not the install kit. Although a new filter might be nice to have. I would really try to get the same model you have in your car though. Maybe a call to Walbro could help you out.

I think your question went unanswered because we'd thought there wouldn't be any more pressing questions in here because the OP's question was answered to his satisfaction.

Personally I recheck threads whenever they've been brought back up lol. Thanks for responding Ben.

very good info on pumps especially the stock fpr
