i would just like to run 25 psi on race gas at the track/dyno and 18-20 street on my built b20b and i have 450's now running 9 psi but what size will be large enough... 880-970's??? i just dont wanna max a injector out thats too small and fry a piston or break a sleeve with it.

 

have you made a visit to the dyno?

 

yes i have and its tuned but 450 will not hold that much power 500-600 whp
i just asking what people have and run now with that much power

 

im gonna try 880's on my set up , they might be pushing it too unless we jack the fuel pressure up
