How Difficult to Complete an ATI Procharger Kit?
How Difficult to Complete an ATI Procharger Kit? I am looking at getting a partial ATI kit that has the compressor, the steel bracket, and I think an 8-rib pulley set-up. My question is how hard would it be to complete the kit with the piping, BOV, boost controller, etc... I don't plan to run any intercooler anytime soon, and I will probably keep the boost fairly low to not max out the fuel system. I would eventually upgrade the fuel system and maybe get a IC but don't exactly feel like buying a new bottom end or rear end. I would like to choose between this and getting some ported heads. Thanks.
You are going to need to save up some more parts.Fuel upgrades is a must,atleast 42lb injectors with a stock pump.Also not a good idea to not run it without an intercooler.The intake temps skyrocket without one.

Not sure what you mean by keeping the boost fairly low, but stock injectors and fuel pump should be good for up to about 450 rwhp, but that is the least of your worries. With no IC, you will have to back out so much timing it will not be worth it; you won't make much power without detonation. No IC = high intake charge heat = detonation = new bottom end components 
IMO, don't put on a s/c until you can provide adequate fueling and a cool intake charge. You just won't be happy with the performance and you will be risking damaging your engine.

Bypass valves are open under vacuum conditions, and close when vacuum reches 0 (WOT).
BOV's are normally closed, and open when the throttle is closed.
Bypass valves are better on supercharged applications for cruise conditions to take the load off of the blower for longer life and better gas mileage.

Again I apologize for any confusion I may have caused.

Am I mistaken in thinking that the fact the ATI is a supercharger it's not controlled by a boost controller but rather the size of the pulley? If i'm wrong please feel free to correct me. If the ATI does function with a boost controller than this might make me consider it even more than I already was.

To get 450 rwhp forced induction would require at least 42lb/hr injectors. Stock injectors will handle 450 rwhp naturally aspirated, but only with a good tune. Even then, you would be at their limitation (100% duty cycle).
Again I apologize for any confusion I may have caused.

I figured you had to be in a different state of mind to say that!!
