Whats The Correct Lph Output For A Bosch 040

[StOjA32]

im about to buy an 040 i wanted to figure out the correct output for these pumps.. ive read all over the internet, all different figures

from 400BHP @ 300LPH to 270BHP at 125LPH ... anyone know the ture figures?

From the Bosch Motorsport Fuel Pump Brochure

0 580 254 040 (Bosch 040), 102 l/h @ 6.5 bar

0 580 254 044 (Bosch 044), 200 l/h @ 5 bar

0 580 254 023 (Bosch 023), 168 l/h @ 5 bar (Rumoured to be the Nismo GTR upgrade pump)

But "Bosch Fuel Pumps have their flow rates defined in N-Heptane as part of their engineering specification. N-Heptane is a pure chemical and does not have the same viscosity and density as standard petrol. Hence the N-Heptane flow rate figures stated should be used as a general guide for comparison purposes only."

Other info I have gathered: (fwiw)
