Default Stock fuel lines, single 255, 42# injectors

How much HP can I get out of this setup? That's what I have now. My stroked bulletproof engine is ready (broke #6 piston in the stocker) and will have to get my money back up for the fuel upgrade. Turbo is T70. Thanks.

I would venture to say somewhere around 500-600whp depending on powertrain

I've actually been researching a turbo build in the 500-600 rwhp range, and many people have been suggesting larger than 42lb injectors. 60lb dekas seem to be popular. It's really important to not run lean...

People usually use 60's for the extra padding, keeping duty cycle down and enough fuel to up boost in later setups. 42's should be just fine for 500-600rwhp. BUT no more especially since its forced induction

I ran this exact same fuel set up for a couple of months and was leaning out at about 6# and 450-500 HP
Since I've added a second pump and boost ref fpr and I've been good to about 11-12# , going to upgrade my injectors soon so I can run 18#s

I would not recommend anything less then 60# injectors and a boosted motor
