Fuel pump recommendations With my mods, so far the stock pump has been ok but I'm sure when I spray, I'm gonna need a better setup so I don't lean out but I was wondering if I can get away with a Walbro 255lph or will I need something bigger? Also what about a "hot wire" kit? I'm on a very tight budget right now so cost is definitely a consideration. TIA |
I just ordered an RFPK - 001 kit from racetronix to go with my fast 102 / 102 setup with a Martin specced cam. From what I understand the hot wire kit is to provide more power to the larger pump than the old wiring can handle |
I'm at about 600 rwhp on a 150 shot With the 255 pump and hotwire kit. Seems to hold just fine, although I'm sure I'm right near the edge |
I'd love a Racetronix p&p setup but that's more than I can afford now so maybe just go with a 255 now and hope for the best. Is a hot wire kit needed for a 255 pump? |
At 426 hp the 255 pump alone will be fine. The hotwire kit is cheap though |
The 255 will be good even with spray? If so that's awesome and the news I wanted to hear. |
How big of a shot? |
150 tops. I'd be too nervous to go any higher, even with a better pump. |
On a 150 I'd say not a good idea. That's what I'm doing but with the 255 pump and hotwire kit |
Damn, burst my happy bubble.lol What would you suggest then? I guess since race season is almost over I can just save for a better setup for next year. Or are you saying you wouldn't do it w/o a hot wire kit? |
Sorry man lol. No I would not do it on a 150 shot. It's not much more money for the hotwire kit |

So a Walbro 255 with a hot wire kit will work then. That would be fine. |
That'll be cool then, thanks for the help with this. 1 more question, My ORY only has a 2.5" outlet where it meets the rest of my setup which is 3" I never thought about this before since I wasn't planning on modding but I'm sure now it's gotta be a bottleneck. How much do you think I'd gain by either having the 2.5" section cutout and welded or a true dual setup? Thanks again for your help. |
With your setup you probably would gain a few hp. I'll give you a similar scenario with my car. My Pacesetter ORY was built with a horrible merge. Had a 3" in 3.5" out Flowmaster merge put in and it definitely made a nice little difference. My buddy's 03 Cobra would pull me by a car or so everytime before, and after it was a drivers race. So that told me there was definitely a bottleneck |
Dano, not sure you want to go this far, but you might want to get a Flowmaster merge with inlets the same size as the 2 incoming legs of the ORY, then a 3": outlet. This will de-congest that part of the exhaust, plus make a better merge of the 2 incoming pipes. It would have to gain power... EDIT- Looks like great minds think alike, HCI2000SS! lol |
Thanks, guess I will be doing something about this for sure then. Another member on here has a Speed Engineering true dual setup he's gonna sell me when I get the money together so it's gonna be that or get this y fixed. |
That true dual setup will probably be worth a few more ponies but not much over a proper y-pipe. G Atsma, I just now saw your post. I like the way you think lol |

The price differences are so small between a 255, 340, 450 just get something with some headroom for the future. Hot wire kit is a must. |
