Depends on level of power, anything over 650whp will require some love...
Our car uses (2) 044 Pumps in parallel running 6bar FPR to fuel for 37psig ;p
Essentially each pump feeds one bank only, with a failsafe crossover. New Alum lines from Tank to front feeds, with check valves...
Keep in mind we use custom RC injectors flow matched to over 800cc @ 3bar.
If this wasnt needed we wouldnt be doing it, anyone telling you they are making big power without these kinds of upgrades is either lying or defying physics. Remember HP is directly related to the AFR, so even at 12:1 for a given power level of say 700whp or more is a lot of fuel. The 2.7L is good just not magical...
