so i was thinking about puting rosewood stage 2 injectors in my truck but dont know if i can run them with out buying a intercooler kit

 

you can run them with out an intercooler. cause the intercooler it just puts colder air, which yes colder air makes more power, but with the stage 2 injectors you might want to upgrade ur hpop so it can support your injectors better

 

what does the hpop do to help the injectors

 

the injectors require oil pressure to open them your stock hpop will run the stage 2 injectors but they require a higher opeinging pressure, so an upgraded one can open them at higher pressures

 

You can run 2's without an intercooler but if you do any towing, it will get hot fast... Do you have gauges to keep an eye on EGT's?

 

I don't think this is true. Stage one or two will require more volume.

 

Really depends on the condition of the pump in question... I have run my 160cc injectors on the stock 15* hpop for over a year now with no issues... Not saying that will work for everyone but you need to check the condition of the pump before assuming.

 

and yes you can run your stock hpop that's what I'm going to do, but the high cc's of an injector require a higher opening pressure and like he said just depends on the condition of your pump

 

Why?

 

from my understanding stage 2s and up use more oil due to the bigger nozzles and empty way faster than a stage 1 with stock nozzles so its harder for the oil system to keep up with them
