| There's more HP to be had with a bigger/beter turbocharger and an ice water intercooler and camshaft change than any change in the spray angle of the injectors. More fuel without changing injector spray angle will yield more HP too. The original engineers spent a lot of time and $$$$ coming up with what you've got for a spray pattern and that includes the 34 to 38 degree pump timing. |

| I agree with the turbo and cooler but rules are 2.3 charger and no cooler I was just worried that the spray was too close to the top still playin with timing but only 2 degrees at a time. Running a Mr. plates cam going to try an offset woodruff key next. Thankyou for the advise just worried the spray was too close |

| Probably should get you set-up with a water/alcohol injection system.....that's good for 60 to 70 HP with the flip of a switch. |

If they don't allow water, they sure as heck won't allow NOS. Around here the stock trucks try running it, but if caught, they don't have to worry about pulling anymore. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".
