Re: How much HP with a mechanical fuel pump?
 

the fuel lines on a 600 sc and an 800 sc only have a 1/4 pipe fitting to feed two carbs

my stock 600's dropped fuel pressure with a regular pump added

he is also checking the fuel pressure before the rail right at the pump

i check mine at the end of the fuel rail

the problem is your fuel system will only flow what the smallest restriction is and a single 1/4 pipe fitting will not feed 800 hp :evilb:
