View Full Version : Confounded by Injector, red ring PN621030

I'm trying to pinpoint the manufacturer and flow rate for the injectors I have. I bought them about 4 years ago from one of our vendors.
The receipt says 38 Lb/hr and it looks like S-Tech or something written next to it, that part is scribbled.
I went out to the car and found PN 621030 on the injector body and there is a single red ring at the top.
My research leads me to a table of Lucas injectors and this injector is rated at 42 lb/hr.
Can anyone give me a warmer feeling as to what injector I have?

Again, it has a single red ring and the PN is 621030.

Wow, i was just about to post a similar question.

I've somewhat inherited a GN and I was wondering what injectors i have.

They have a red ring, PN 621030 on one side and D1163AA on the other. They also have a small "swirly" logo molded into one side.

If anyone can come with some info i would be very greatfull. I just need to know size and for reference how much power they will support.

Thanks :) Mike

Some of the F-Body and Mustang boards say 38. The site above says 42. They also peg our stock injectors at 29.7, which is dead on.

Thanks, Scott.

I'm surprised by this because the vendor I purchased them from is one of the best and I find it very odd that he would make a mistake like this or mislead me. :shock:

Maybe that is why I seem to be running rich all the time, I have a chip set-up for 38 Lb running 42 Lb injectors. :eek:

On that page they list them at 93.3HP@80%

Does that mean a set of them would support 559.8HP?

I would not belive you could get that much HP out of 42 Lb/Hr injectors at 80% DC.
