Advice on 360cc Red Top Injectors


Recommended Posts

I am doing some research into forced induction and am wondering can anyone advice or share there experience please on changing injectors

I am looking at 0280150431 which are from a Saab 900 Turbo.

The info I could find (http://users.erols.com/srweiss/tableifc.htm#BOSCH) find 0-280-150-431

# LB/HR: 34.15

# CC/MIN: 358.9

I read that these red injectors are good for 340 bhp at 3 bar!

I am looking at 325bhp but do I really need to upgrade my fuel pump to a 4 bar?

I ran 321hp with those on 12psi supercharged and 400hp 11psi turbocharged. 3 bar reg on the Supercharger' date=' 4 bar reg on the Turbo.

Thanks Kev. I guess the question is what supercharger did you run? And like for like with a Rotrex setup would a 4bar be needed to run 325bhp?
