I went to try the juice 2 nights ago without knowing which fuel psi I should have. I adjusted it so I had 46psi vacuum off, instead of my normal 42psi. I had the bottle heater on and pressure was at 1000-1050psi or so. My plugs were gapped at .035 and my timing was retard as well. Everything was correctly set up. I had the 100jets on there. It's a NX wetkit. I have all the gadgets for it. Purge, fsps, window switch (3000-6000rpm), wot. So I'm in 3rd gear slowly accelerating and I hammer it. I'm in the 23xx rpm and just waiting to hit the 3000 mark for the system to activate. When it hits it, something happens...A BIG "engine buck" of some kind so I let if off right away, not knowing what was happening. At least I know the WOT and msd window switch work fine. I know the wiring is dead on. Just not sure what happened...
1) My Fuel safety pressure switch is set up at 35psi. I've heard that it shuts down sometimes when it comes to close to that point. Could it be this that made the bucking ?
2) I have the 255lph high pressure on there so I know I have enough fuel thats gonna be pumped in... Also have the 24pds injectors. Could "hot" fuel make the engine buck ? By that I mean this. The fuel is taken from the fuel rail to the fuel selenoid. I'm not sure if this fuel is "recirculating" or if it's just there in the line, warming up waiting to be entered in the fuel selenoid...What do you think ?
Thanks
