ok i was wondering how high the 42# injectors can go at 80% duty cycle, i am using the racetronix single pump and plan on using a msd bap.

my goal is right around 600rwhp, and will the bap help when using nitrous i read it was good to use while running boost but does nitrous count as well.

thanks

 

ok i read there good for about 500hp but i still would like to know if its a good idea to get a bap with 60# injectors, or is it not needed for 600hp

 

are we talkin NA or FI?? 42# injectors are good for around 550-600 naturally aspirated RWHP if your going FI then you need 60's

 

I have taken the 42s with a voltage blaster to 725 rwhp hundreds of times.
with them maxed on a dry nitrous shot.
However I would opt for the 60s to keep from maxing out above 650 or so.
Another buddy of mine took his 60s with a BAP to 800 rwhp. But he didnt even have to increase the voltage.
