Professional Products FI

[70rs468]

Has anyone heard anything about Professional Products multiport injection? i am considering it to be an upgrade from my Holley 950 double pumper. it troubles me now to constantly have to re-jet in the spring, summer, and fall for optimum air-fuel ratio that is normal with a carb. I know very little about any systems. I have a bbc 468 @ approx 550 hp now. Any feedback would really help.

it's not a multiport efi system, it's multipoint.
it's a throttle body with integrated port-style injectors hidden in what'd be a holley's fuel bowls shooting down below the blades.
retrotek speed has a similiar system (very similiar....)
there's good info about it on PP's website.
they're still rolling out various models.

FAST has just released a neat fully integrated PHD style system that looks real promising also.

After seeing the quality of their other products (including their infamous exploding "SFI Approved" dampers) I'd be reluctant to put any Professional Products stuff on my engine.
