Subject: Re: Hot Headers! Is this normal? by Mekanic on 2008/9/13 10:48:55 I'm here!!! (insert captain America "Dun DUN DAAHHHH" here) For a 383 build like that your injectors are quite small. Here is a few things to chew on. According to DRM they install a different fuel pump and adjustable fuel pressure regulator. Your fuel pressure looks okay, could you tell me what the pressure looks like with the engine off and the rails primed? To do this just hook up the gauge, turn the key on (hear fuel pump come on, then go off) then tell me the pressure, and if it drops at all. DRM also says it does "custom computer calibration" But it has no mention of using any larger injectors on their site. To sustain the 470CHP that DRM claims, you need at least a 36lb injector. The stock LT4 injector is a 26. Now also depending on how you are getting fuel enrichment for your nitrous you may need to up that even further. Hope that helps! |
