i'm building my own version of the STS turbo kit for my truck... but i'm limited on money... will the stock injectors flow enough fuel to run between 5-7psi...
i WILL upgrade them later to run more boost, but will the stocks support what i need for a couple months till i can pick up some bigger injectors??

 

tons of views.... no responses.... i'm serious... need input

 

My turn. How much HP will 7 psi make on your own version of the STS turbo kit?

Don't do it. Best way to kill a blown engine is to run it lean. Stock injectors cannot keep up with the fuel demands of the blown engine at high RPMs. A set of L injectors is much cheaper than replacing your engine.

To paraphrase my favorite quote - at 6000 RPM each cylinder experiences a power pulse 50 times per SECOND, that's 50 times per second for engine eatting detonation to occur.

 

The only way for a stock injector to supply enough fuel for a blown application is to spike the fuel pressure. Your truck uses a returnless fuel system. Fuel pressure is maintained by pulse modulation of the fuel pump. The PCM controls this. Depending on how much HP you plan on producing you may be able to get a program to have the PCM spike the pressure. Just changing the injectors will not work is you do not have the fuel volume behind the bugger injectors. I suggest you find out how the supercharger companies take care of the fuel requirements. I believe they use a chip that reprograms the PCM to control the fuel as well as timing stc...

a simple "no" would have worked... i understand how the concept works... i just needed to know if the stocks would work... would 39Lb injectors suffice?

 

No. The question cannot be answered unless you tell us how much HP you plan on producing. Do you understand that concept?

39# would work for that boost, I use 39# on my truck with no isues running at about 8-9lbs off boost

 

read the whole first post.... 5-7psi at first... with this engine, and depending on who i have do the tuning... it could be 300hp, it could be 400hp.... in all honesty, i'm looking to about replicate, or beat by a little... STS's number, which is 348hp... by the way, they're kit uses 39lb injectors... i just wanted your guy's opinion

 

this may be stupid and off subject... what do your initials stand for JMC.... they're the same as mine....
