Hello all, I'm trying to figure out a mathematical method to figure out how big of a surge tank I will need for my fuel system. I don't want to drain my surge tank and lean my motor. It's a carbed 302 with a blower. Here's my plan... HP goal, 500hp, by my calculation I need a fuel pump that will push at least 50 gallons per hour. I'm trying to decide between the Holley black, Mallory 4150, or a Magna Fuel 275/300. Now whichever I choose, I will be placing the HVLP pump after the surge tank followed by a FPR. I will also need another HVLP pump to feed the surge tank from the cell. How big of a pump do I need to feed the surge tank to keep it full. From what I've read on previous articles is that you shouldn't regulate the pressure to the surge tank. You need the surge tank constantly full especially in drifting (not my plans, just something to keep in mind), just make sure you run a good return line from the surge tank to the fuel tank. So with that said... 1. How big of a surge tank do I need? Or give me an equation to figure it out. 2.How big of a fuel pump do I need to feed the surge tank from the cell? 3.Also for a DD/Road course setup has anyone experienced these pumps I've listed? Thanks in advance.
