  • Plz reply what did u do to get that spray pattern and does it help any?

  • @Greenmonoluche

    That is what it should look like if everything is working properly. Even on a stock setup.

  • looks like your injectors are clogged or something cus they shut off and on they should stay steady.

  • @YoungerPrice They are just fine when at idle they will alternate when it is revved up they dont shut on and off. If the injector was clogged you would not have a good spray pattern like you see in the video.

  • Did you have any clearance problems with the fuel inlets on the back after adding the injector pod spacer?

  • @RockstarATG

    Yes, you will have to grind the casting a little bit or the fitting will hit on it.

  • @78pacervette well see mines a 95 and the wire going to the injectors are black and brown an also mine sprays both injectors at the same time is it ok?

  • whats the pattern inside your throttle body spacer? im looking into getting one.

  • @78pacervette actually they always alternate. they just alternate in much faster patterns. beauty of having a computer is they can process much faster than our eyes can see.

  • @9c1chevy I have an 83 with a 383,ported Vortecs with 2.05/1.60 valves, Reed Custom grind roller cam, Doug thorley Tri-Y headers, Edelbrock TPI base, SLP TPI runners that have been siamesed, ported plenum, 3,400 Yank stall in a 4L60E, and 4.56 gears all running on 2001 LS1 0411 PCM running a modified 2001 Express L31 350 calibration. It sure is fun taking people by suprise with an old G-van.

  • Did you feel a noticeable difference after the mods?

    I had an 89 s10 blazer with the 2.8 TBI. Soon after I got it I installed a throttle body off a 350 and stuck my 2.8inj/reg on it and it ran like a champ, but then I sold it.

    I now have a 94 s10 blazer with a vortec 4.3

    I'd like to build a TBI motor though, since I always had the best luck with them when it came to reliability

  • @YoungerPrice Youre an idiot...these a pulsed off and on...they are operating just perfectly...they actually pulse so fast it looks like its solid...
