    Dyno-ed today--Fuel Injector Question

    I had my car with the new motor (750 miles on it so far) dyno-ed today and found out that my stock injectors weren't putting out enough fuel. Even elevating the injectors to 100%, I'm still not getting enough fuel and am running far too lean. Luckily, the GREAT guys at LG Motorsports said that if I get some new bigger injectors and bring my car back up there, they'd tune it again for a fraction of the cost of the original dyno. In addition, they informed that my valvesprings weren't performing up to par and recommended Comp 921s to give me all the HP possible from my setup...I have the Patriot Golds currently. My question is, is there one brand of injectors that is better than others? Should I go 36# or 42#? I'm wanting to order some by tomorrow so I'll have by next weekend. My numbers weren't impressive at all, so I want to get all I can before I decide to go with a larger cam.

    415 rwhp/422 rwtq are my lean #s

    Thanks

    Seeing that you're running N/A, I would say that 36lb/hr injectors should suffice. But didn't you ask what the guys at LG Motorsports recommended?

    I mentioned that I had bought some 36# injectors from an 04 cobra, but that the plug type was different...they said these were also probably too short and recommended some that I can't remember, but didn't mention # rating. They acted like 36# would be enough...sorry, was kind of lost in the moment.

    Something like Delphi should work fine.
