I did not think I could run the 2.8 pulley with the 42lb injectors but I was on the cobaltaddiction website and see they sell a stage 3 kit with a 2.7 pulley with 42lb injectors .So can I or can't I ?Thanks for any input.

 

You can run a 2.7 with 42's, but I wouldnt go over 3000 rpms, if you do it goes BOOM!!!

 

to be safe with the 42lbers id stick to 2.9 inch 2.8 is pushing

 

must be a typo on their part

 

they also have a 2.85 on the 42s
http://www.cobalt-addiction.com/performance.htm
one is a stage 2 the other stage 3
and from the TAG page Siemens 60lb/hr @ 43.5psi Flow Matched Fuel Injectors
Item Number: 14128

Required with any pulley under 2.8".

 

they have some awesome apperance parts there, but
thats why you dont buy the cobalt addiction stage kits...
plus i heard their tunes suck


i see in your sig that you have a 2.79" pulley... i'm assuming thats on the stage 2 #42's... you should get the #60's asap

 

I am I already ordered them paid next day air but I did not know fedx does not deliv on sat. and I am going to get it tuned by doc 2marrow. I was just hoping I could install the 2.8 and tune then install the 60s I have comming at the april MD meet and retune.

 

as long as you dont go WOT you should be o.k.

right now i'm running a 2.9" on gm stock injectors. as long as i dont hit wot or max. psi my injector duty cycle is well within normal range.
i do have the #42's, just no time for a tune yet
i had to throw that in there so you dont think i'm hating on you... i'm in the same boat as you.

 

My problem is I have always been a now type person fuckwaiting I want it now I wish there was some where between here and his place that sold them I would just stop and buy the damn things LOL

 

do you have the lucas wiring harness?

if you do, i don't see why you cant go to an auto store and buy lucas #60's

 

nope its on order with the injectors.damn

 

that sucks bro. looks like you will just have to wait.
on the brightside, it's st. patricks day... go have a few beers and you'll probably forget that you wanted that stuff in the first place.

 

yeah im running a 3.1in pulley on stock injectors i cant run wot passed 4500 rpms. and yeah most places have the wrong info as far as pullies and injectors. most places say that 3.0-3.1 is safe on stock injectors even though the stock pulley is almost to much ofr the stock injectors.

 

Should have gone to ZZP or Intense for injectors delivered quickly. There are other vendors, these two I've asked to overnight and it was to me by noon. I didn't think to ask where they were coming from.
