Or you can use the ez efi with port injection and use it up to 1000 hp.[/QUOTE saidI was on the phone with Professional products today tossing the Idea around on my TT 67 Dart build. I am at the point to make a decision to go carb or EFI.
They told me on the phone with their Powerjection 3 kit it will support up to 550 HP and there is NO WAY to increase the Injector size to allow for more HP because the Injectors are inside. There are 4-62lb injectors inside. They said for my application that could see 8-900 Hp or so I would need 2 systems and Dual Quad it. They piggy back the other throttle body and only use 1 2.5 bar map sensor which they say is good to 20lbs of boost. Kind of a Sale on words because it comes with that sensor on the single set up and it is only good to 550HP I even told him that and he laughed. 20lbs of boost in a V8 will way more than pass that mark.
The whole kit unpolished Dual Quad set up is $2480.00 for 8-62lb injectors and another 165.00 to upgrade to 8-75lb injectors. He also told me I could get away with increasing the fuel pressure with the smaller ones to 56lbs and it would act like the 75lb's?
Sooooooooo my thinking is if I could do the Direct Port Injection with the FAST system I may just go that route!! I will make some calls tomorrow and find out if It would work for me. Does anyone know if it will work with a BOOSTED APP??
