Wondering if a single walbro 400 will support 550 RWHP, and if a stock regulator from a truck engine with return fuel system would be able to keep up. (didn't know if it can flow enough to keep the pressure from rising uncontrollably at idle/low demand)

My stock LS1 regulator gets a little overpowered on stock voltage(like 62psi idle) but with a hot wire kit it sees 72+psi at idle, but made 688whp through the auto, 9" and 28" drag radials. Single walbro 450 on race gas. made 600whp on pump and no hotwire kit
