That is serious pressure. . .technically according to his analogy that still wouldn't be enough to render the pump useless since even under hard acceleration the pump only uses 1/3 of its capability meaning at 40-47psi random honda spec. . .120PSI would be needed to max out the pump. Thats just ridicules i dont care what he says 120psi to max a stock pump that dosnt even make any sense.
