LOl, im just curious how that gusher of an injectors will do idling around town daily driving or will it be a tuning nightmare I do feel myself becoming a meth head soon either way

 

Turn the base pressure down....idle and tuning will be better thats why everyone likes low imp injectors better

 

my old setup made 550 with 42's...since then has gone thru a bunch of changes...im scared to go any higher with it now with a stock lq4

 

I'm not going to pretend i know alot about injectors because i really don't. Does that mean that i may be able to bump up to around 9-10 lbs boost without getting bigger injectors by using my 42#ers and my 185 inline and 255 intank? I dont know my current IDC but its probably pretty close to 100%. I am making a disappointing 351 rwhp now

 

I dunno Ken Im lookin at all this as well, but 351 is really not that bad considering it seems like you have a basicly stock 5.3 with a radix and low boost... plus a 4wd at that. I would not be too upset, thats well over 400 at the crank, shoot a nice cam and some longtubes will do wonders for that setup

 

I'm running the 255 with #42's and a 3.0 pulley on my Radix. I was at 98 and 100% when WOT with 11 psi boost. My fuel pressure was in the neighborhood of 62 psi, it never went lean but I was told if I added any more power then larger injectors should be considered. You guys have helped answer a few questions that I have had right here in this thread, Thanks.

 

OVERKILL YOUR FUEL SYSTEM IT IS THE SAFEST WAY NEVER DO ENOUGH TO ONLY GET BY

what if your waist gate fails and you need the fuel and also i believe with the 10% of ethanol in the fuel now means you need MORE injector to compensate the adequate amount of fuel needed for the same HP level you could achieve a couple years ago with the same said injectors

 

exactly thats why i changed my setup ...i run 60's now and still the 255 hot wired and meth ...works great.

 

Well, Guys,..... i decided not to play around and wonder on if 42's are enough or not... so i ordered a set of 60's, called Allen Nelson for a retune, and said what the hell and going to swap the 7psi spring in for a 10psi spring, and order a meth kit as well... lol

 

Where are you getting your injectors at ?
