Bad idea. |
Variable resistor relays aren't what I'm thinking of, that's not going to run higher than input voltage, is it? 14.5v in, 18v out? |

You already bought the stuff. Just run what you got and see how it works. Not sure what you did, but I had my Racetronix harness built ready to accept their voltage booster if I need it.
People are selling slightly used injectors on LS1tech all the time in the range of 60 - 80 lbs. |

Once you start getting into the higher lb'ers they get fewer and farther between. That's where I got these little guys.  I'm keeping my eye out for larger all the time though. Cheap, of course.  |

I found some 103# but I don't think you're that cool yet.  |

| At some point do they start using 2 sets of injectors? A smaller set for idle and up to a certain level then kick in a second set? |

| Something else thats "boost referenced" remember your intake valve springs will be weaker by what ever psi you run X the area of the valve. |

I'm not sure about other ECUs but MegaSquirt can control fueling down to microsecond increments so has no problem at all idling an engine with gigantic injectors.

Unless the injector isnt that quick. |

Guess it should also be mentioned that the effective fuel rail pressure also decreases the same amount without a rising rate regulator. I still dont see why you need #60 injectors. |

| Hopefully I don't lose too much efficiency with it being so thick but I know for sure it'll fit between the frame rails! |

So...I bought these 60s... And I got that wastegate from Zac.
Need a BOV and some tubing and that's it. With these 60s I think I'll be maxing out the next weak link. Turbo? Headgasket? rods? Who knows! I guess I should start shopping for a replacement motor to swap in case something goes down. Obviously I'll be upp'ing the displacement if that happens. 6.0 here I come. |
