Single pump Alright, I'm building a 1986 rx7 with a 5.3, LS1 intake, mild cam And I'm trying to figure out what kind of fuel pump I need to Run. It doesn't have to be an in-tank pump because I'm running a fuel cell but I want to run a single pump that can support Enough fuel for 700 horsepower on E85. |
Come on guys |
walbro 450lph |
U think a single 450 will do? |
I assume this will be a turbo setup? |
Yeah it's a turbo setup |

U think a single 450 will do? What size injectors will you run? What base pressure and max psi at full boost? Plan the entire system before you start buying parts. |
I'm thinking 80bl injectors on 10AN lines with a single pump on e85, I'm not sure how much boost it will take to get me to 700hp on a92mm t4 turbo,so I just need to know wich pump is capable of flowing that much fuel |
Full boost (max psi) directly affects if the pump will keep up and if the injectors will be able to work at full boost through redline (assuming boost reference regulator). Keep in mind a fuel system in N/A configuration will support more hp than those same parts in FI setup. 80# injectors will do the trick. 450lph should feed those injectors very well up to 20psi or so (lots of variables). |
Hopefully I won't have to turn the boost that high |
What u think about the holley 12-890 think it's capable? I'm just asking because it looks like it be a bit complicated to do all the pluming using that 450 |
