Where to get injectors?
Hey guys what are the best 52# injectors and also where should I buy a hi flow fuel pump at? I am building a 6.0 with forged pistons,rods, and rod bolt, head studs. Also it will be blown with about 10-12psi and 100-150 shot of NOS. Please let me know which fuel pump would be right for this setup. Also one other thing I would like to know what CAM would be best for this! It is a whipple blower. Thanks guys!!

they sell some 42lb/hr(@59psi) that will plug/bolt right in. that is the largest that i have heard of.
if you want to go bigger you will need to do some modifications to get them to work. shim the rails, tweak the fuel cross over and solder in some new conectors.
here http://www.supras.com/~riemer/sonict...rs/RCtech.html is a long article that has some very interesting info on injectors, some parts i found espesialy interesting.
"We have found that the stainless steel Lucas is, by far, the finest in construction and finish. The stainless steel innards, exclusive to Lucas, are a work of art. The unique metering disc assembly is years ahead of the, 40 year old, pintle design. Bosch, Siemens and Nippon-Denso are also excellent injectors that are used worldwide."
"Most pintle type injectors fail at 86%/88% and the Disc will usually go to 92% +, depending on system pressure. All must cycle smoothly up to 85% to Pass. Bad injectors will sometimes go "static" at 70% or so and are discarded. NOTE: Most pintle injectors will increase flow rates up to 88%, 92% with Disc injectors, and then go "semi-static", half open-half closed, just before going full static. This time-out event occurs at different time/pulse width durations, in different injectors, but always produces a 50% or so Duty Cycle flow rate. This extremely dangerous situation will usually occur at the worst of times, full throttle-max boost-high RPM- just when you need 100% fuel delivery you get 50% and go dead lean. BANG!!! This problem seems to amplify a bit at higher pressures."
