Question... Would it be over kill to skip the 42# injectors and go to the 60#s on a stock pulley SS/SC? or has this been done before?
I do plan on changing to a smaller pulley, but I would like to see what this car can do with all the bolt-ons/cooling mods before i drop the pulley size.
It would be like the GMPP stage 1 just with bigger injectors. Please correct me if I'm wrong.

no it would be saving you money because it sounds like eventually you will need em...

mo boost = mo fast

shreveport eh?? where i was born and raised although im in Florida now just saw that thought it was interesting...btw Geaux Tigers! (although out offense is terrible)

BTW its not a waste you will just get terrible gas mileage until you get tuned for them and when you do it will go back up!

Um...yeah...60's on a stock pulley is idiotic because the point of increasing injector output is because you increased air input to the point where your injectors are maxed out.

You don't need "cooling mods" on this car with a stock pulley because the manifold doesn't get hot to the point that it's necessary if at all.

^Look how far Ralliartist got on stock pulley with cooling mods and whatnot.

You can do it but you must have a tune ready when you put the injectors in or the car will practically flood and foul the plugs.

As long as the car is tuned for them you won't know the difference.

no doubt, iv only been here about 2 years. air force said it was between either this or north dakota.... its not too bad, casinos and what not are pretty nice. little warm down here

no point to going to 60# on stock pulley. you can do it everything will be fine and dandy, but i would just wait until you got the smaller pulley.

there is NO performance boost from getting bigger injectors on stock pulley car, you have plenty of headroom in the duty cycle and your def not leaning out.

Superman_Davin

So going to 42# injectors doesn't give a 25 HP increase like GMPP claims? (I know its all in the tune)
Why I'm asking about the 60#s is just a hypothetical question. Obviously no one has ever attempted this or I would have read about it. I really don't think anyone has used GMPP Stage 1. Seems like everyone has gone to Stage 2, or custom with the 60#s, or any combo but just the larger injectors (save Ralliartist). He had something going. I want to see with the right combination of bolt-ons/support mods, what this car can do without a smaller pulley.

Changing to bigger injectors won't do anything, even if your tuned for them. If your not tuned for them, and throw bigger injectors in, I'll be surprised if it even starts. This will just be a good supporting mod for later. I have 85 lbs injectors in my Syclone, but they only dump about 55 lbs. Its tuned that way because I know in the future I'm going to need all but 80 lbs during full boost and throttle.

I'm not looking for huge amount of power for the bigger injectors right away. I'm looking for potential.
I usually keep to myself about technical questions... look at my post count and member number.
I realize what needs to be done; tune for the bigger injectors for now, save money for other parts later.
My whole thing about this is I don't want to by the 42# injectors just to turn around and buy the 60# injectors later on.
Besides, isn't the new turbo SS running on only 33% or something close to that of the injector duty cycle?

are you planning on going gm stage 1? Maybe buy hp tuners and learn to tune yourself.

sounds smart to go ahead and get 60's now, as long as you can tune them.

zackss

get the 60's if you will need them down the road

cobaltR

You can buy the 60's and save them for the pulley, but no need to put them on now with a stock pulley. I had just had my car dyno'd with just an airbox mod and I was running pig rich on the stock injectors. Putting the 60's on would be a bad......

Superman_Davin

That's what I'm kinda leaning towards at this point. I will be reading a lot when I go on this deployment in January. I obviously won't know exactly what to do, but will have a pretty good idea when I'm ready to start tinkering with this car.

Greased

all in the tune. you could put 60# on a stock car tune it and be running lean.


i think the op has a good idea. like someone suggested before though, if your really looking into saving money buy hptuners and learn to tune yourself. then go and and piece together your own stage kits. Greatest potential there. If you dont have the money/time for hptuners and the learning curve, i still say skip stage kits and their box tunes and find a local thats good w/ hptuners and have him do your tune

theneelster

Cooling mods that don't increase air flow/compression do nothing but fight heat soak; they don't reclaim power, they don't increase power. A second h/e/dual pass/option b/anything else coolant related does nothing but reduce intake manifold temperatures as compared to without.

There is no reason for cooling mods on a stock car it's a waste of money that could be spent for mods that actually increase power.

Superman_Davin

thanks for the info peeps, just wish i got some opinions from some of the more advanced tuners here on CSS.net

cobaltR

Of course it's all about the tune, but it would be pointless to put 60's on a stock pullied car and then tune it....there would be really no advantage until you went with a smaller pulley. Instead either just tune the car with stock pulley, or just save up and do it all at once, ie. 2.8, 60's and tune.

Greased

ehh, they like a good controversial statement. you might bait them in with an idiotic assumption at which point they will reveal their knowledge through a barage of insults.
jk
but seriously, there is nothing really "advanced" about your idea, your just going backwards, most people get a pulley then injectors not the other way around.

theneelster

Well...the deal is this...what are you going to do with the extra fuel? If you aren't adding boost then you don't need it. Get 42's then when you want to up the ante sell them and get 60's.

Superman_Davin

got it...thanks guys

G85 SS

Yea, he is the fastest stock pullied Balt to my knowledge....Raguardless of being stock or not, a car running cooler whether it be stock or not will be faster....
