ROTFLMAO

 

just go with and IC its safer and nothing to lose besides the money u spend on it

 

i would do an intercooler i have a non ic sts and im tryin to get one and i have only had it for a week

 

It's about time you recognize the importance of me in your life!

All I was trying to say is hot gases expand and colder gases shrink. If you cool a gas it will increase in density and decrease in pressure in said vessel/application.
gmcandcaprice...In essance, the point of a Forced induction system is to increase the amount of air in the combustion cylinder so that more fuel can be added. The best/ideal way to do that would be to force freezing cold air into the cylinder at insane boost pressures. However when you compress air you heat it up. The more you compress it the higher the temperatures will climb, the more the air will expand, the less dense it will become resulting in less burnable oxygen.
There is a point of diminishing returns, where that is I don't know enough to say but if you look at the graph that Henry (stoichiometric) posted...you'd have the same amount of consumable oxygen if you were boosting 100 degree F air at 20 psi as you would running 600 degree F air at 50 psi(diesel guys ).

 

thanks everyone for clearing everything up, and for all the physics lessons. How easy and how much roughly would it be to plumb up my own system. Has anyone found a universal IC setup on ebay that will work. As in a IC and all the plumbing. I want a good setup, at an affordable price.
thanks

I did my own IC with my original STS kit (they didn't have ICs back then lol). There are pics somewhere on here of the setup. It was pretty easy. I used 3-4 90* 3" bends.

 

Get the IC... just remember to take your boost reference from the intake for the waste gate

 

Get the intercooler, my boost gauge still shows the same as before intercooler (6lbs.) and no noticable increase in lag but much cooler Iats.

 

Since this may be relevant to his application after the I/C install, where did you guys tap into the manifold for boost reference? Was it at the same location most people use (pass. side aft, plastic tab) or somewhere else? Also, at which port did you hook that line on the wastegate? I ask this because I added an in-line I/C after my original install and saw a big decrease in boost. I then added an AEM Tru-Boost and started playing with it (still am) to get back where I was and the truck is acting "strange". I am not seeing much boost under acceleration, but when I layed into it at highway speed I saw over 7 psi. The tech guy at AEM suggested reversing the vacuum lines coming off the turbo and wastegate at the controller solenoid. I haven't tried this yet. But I do not have a reference line from the manifold back to the wastegate, and I asked him if I needed it and he said no. After reading this I think that may not be correct. I am using the TiaL that comes with the STS kit. Not trying to hijack his thread, but maybe getting some insight on my problems will save him some headache. Also, I believe "Just Intercoolers" on Ebay has an I/C for our trucks. Piping might still have to be something you have to lay out yourself but I believe they sell all the things you will need. Thanks!!
