I got a supercharged 97 cobra makeing 445 to the wheels and wana make it around 550 to the wheels. I allready talked to my builder and were gona be installing a FMIC, more boost and fuel. The car has a 225 in tank pump with a T Rex inline pump with 42lb injectors. We allready desided on some 60lb injectors for the upgrade but I'm worried about the fuel lines and pumps at that HP level, anyone know anything about this? Should I go with aftermarket fuel rails or the intire system? Any help would be nice, I'll be droping the car off sometime next month for the install.

Ya I ment 225lph pump, ya I figured the lines will be ok but they will deff need to be swaped out vary soon I realy don't wana risk fuel starvation at 20+psi. I think Areomotive makes replacement rails for it so I'll pick them up and leave the hard lines stock for now.

I'm running a bosch 044 inline pump plus an intank 255 walbro. Currently at 526 hp with plenty of fuel. My tuner said I would be good to 600. Stock lines and rails on a 97 cobra manifold. The return lines make your regular fuel pressure a little higher than stock with a good inline pump. That was compensated for in the tune.
