i just got my car back from a local shop who put in some gauges for me and they are telling me i still have the stock injectors. i have had a 10lb supercharger on my car for 12,000 miles and i know 38 lb injectors came with the kit and the people i bought my car from told me he put 42's in. i have two sets fo numers on the injectors does anyone know if the stock's do and if so what they are...i checked vortech and ether numbers matched anything

621030- part number i assume
1842- not sure what that one could be

What year stang do you have. 42 lbs sound right for a 10psi charger. I was gonna buy an 8psi and that come with 38 lb injectors.

I have 19lb injectors and all mine have written on them is in the top right hand corner that says 281 and on the bottom says 0280156610 Thats all.

i have a 2001 i think they are 42 . they look exactly like the ones on the vortech website.. just i couldnt match the numbers on them with any numbers on the website. the only reason i was worrying about it was for the first day i had my a/f gauge on it was running dead lean but now it is running stoich to rich.. so i am not worried

Cool... what are your quarter mile times in that thing?

what color injectors are they? 42's are green usually

i dunno first hand 1/4 mile i am going the 10th of sept. but the guy i bought it from said he ran a 13.6 with spin threw 1st and part of second
they are black with a red ring

mdvaldosta

red... those are 30's usually (I say usually because the industry standard for 30# injectors is red - although not ALL manufacurers rate with colors)

the kit came with 38's so thats probbaly what they are
