Default Smokem... Injectors...

This is targeted right at you... Thinking of a new set of custom injectors for this season, what do YOU think I should run?

Spec on truck
  • Typical Pump Mods - At Runaway
  • Re-Indexed and Ground Throttle Shaft
  • DennyT Stage2
  • Timing To The Head
  • Powerstroke Intercooler
  • Silver62 Turbo
  • 4" Straight Pipe
  • Walbro 392 Lift Pump w/ Big Lines

Truck is used as a weekend play toy Pulling and racing.

I have an idea, do you have an idea of what the peak static timing might reach?

From my reading and teh little bit of info out there *Should* be about 2.4mm of lift... or around 22*

Was looking at skipping some teeth, I can do what you think will work best though.

,
not to interupt, but rswords, any problems with chugging in the bottem end with the timing that far advanced, i put my pump to the head sunday and the truck sounded like it was gonna fly apart, so i backed it off to 3/16" advance and it runs great.

What size are you interested in, target flow? If you stick with the 155° pattern, you could use a sac style base being 0.011, 0.012, or 0.013", and modify it from there. Cost will be the other issue, depending on how much you want to spend.

well I'm running 6x16's now, You have told me that you can build a 5 hole injector that will perform better. Thats what I want!

I'm running a 9mm head still if that changes anything. I'm really just wanting to try something different.

Maybe... Maybe not...

I think I'll keep them and see which perform better! I'm trying to get everything how I want it and then I'm gonna rent the dyno for an afternoon and do some tuning.
