Just wondering what injectors to use with my saleen blower. Came with 30 pounders but that's meant for stock setup with stock boost and I will be running 10-12psi. Should be around 370-390rwhp.
Yes they will, two ways. You can push them to 95% duty cycle bringing the maximum fwHP up to 530, or you can run them at higher than 39.15 psi differential (Ford's standard) which increases their maximum delivery rate.42s will work. They will handle much more than 470 flywheel hp.
