Fuel Injectors for High HP mills?

I am looking for larger high impedence fuel injectors for my car.
50# 60# and 65#. what companies are you guys buying your injecotors from?
I see that racetronix is selling the 57# Siemens some other companies are selling the siemens injectors as 60#
I dont understand why some manufacturer advertise at different duty cycles I assume that the Siemens 60# is the same as the 57# but at 100% Duty cycle.
This Co seems to be selling 65# but I dont think that that style fits our cars.

Ricardo,

I was looking into putting these Mototron 65# injectors into my 347 tubo. There aren't many ford guys using them, but they are real popular with the F Body guys. They will fit, but the 65# rating is a little bogus...they are actually 60# injectors re-rated to 65# by precision turbo.

I'll probably end up using the Seimens 60# injectors instead.

Where are you planing on getting the Seimens?
 
Don't know...HP is supplying what ever injector I want with the kit, they said to tell them which one and they will buy them.

Ricardo,

I've decided to go with low impedance injectors on my turbo car. Here's a place that sells a resistor box to use low imp injectors with a stock EEC for $395.

I Just finished selling my 42s on ebay. I think I made the decision on the
Siemens 55 series from racetronix.com They have the Old style solenoid and the spray pattern is similar to the stock Bosch units. And they are rated at 80% Duty cycle so I think I have some cushion incase I need more.

I am surprised more people didnt post on this thread??? :confused:

That's because most people haven't exceeded the HP that a set MSD 50s and a 255 lph FI pump will support. Unless you are running a turbo, whipple or an AR, the 50s should be plenty.

BTW, I'm going with dual 255 lph FI pumps and 83# low imp injectors on the v8 turbo SC.
