RE: one more thought on the motor
all vortechs make boost at idle as do all paxtons all prochargers and all roots blowers. thats a fact. if its spinning, theres boost. if you wanna try prooving theres no boost at idle i suggest we run a hose from the outlet on my vortech and shove it up your cornhole and start the truck and see what you do. where the boost goes is all that matters.

Dude, both "ponyfreak" and "mad1stgen" are two of the most powertrain knowledgable people around. You just can't come in here and say that they are both flat-wrong. If you had boost at idle, then your engine would be running way lean and you would burn something out. Get a book and do some reading.

"your engine would be running way lean and you would burn something out. Get a book and do some reading"
i think you need to read up on tuning. with the right tuner you could have 100% duty cycle from the injectors at idle if you wanted to. Ive seen as big as 48# injectors for our motors I'm sure they could do something about your lean condition but I'm no motor expert here.
now does the bypass valve on a blower take the place of a blow off valve on a turbo or is it like a wastegate? Yes i know a wastegate deals with the exhaust side of the turbo but it limits the boost. so i guess what I'm asking is does the bypass valve limit boost or does it "blow off" pressure during shifts? i wouldn't think you would need a blow off valve during shifts because if the motor slows down to shift so does the turbine in the blower

One of the biggest reasons for a blow-off valve, wastegate, whatever you want to call it, is so that the engine can idle correctly. It is reliant on the TPS among other things.

RE: one more thought on the motor
umm if the blow off valve / wastegate works off the tps how do they put turbos on cars with carbs? I never knew carbs has TPS's. the blow off valve and wast gate works off of pressure. in no way is a supercharger/blower or turbo controlled by any computer. well unless you have some type of turbo timer or electronic boost controller. correct me if I'm wrong but i think i might be right on something for once or at least part right.

I was talking about newer cars, like ours. And yes, the car must be reprogrammed when a booster of any kind is installed, so the computer is involved.
In the case of carb cars, the wastegate is connected directly to the throttle cable/linkage via another cable/linkage. Not the best way to control it, but that is why we have computers now.

RE: one more thought on the motor
umm try that again the wast gate is connected to the wrong side of a vacuum motor. when it sees pressure above what it is set at it opens the waste gate and relieves the pressure. this is how you adjust the boost on a turbo. you basically but a valve in the vacuum line going to the actuator to control how much pressure it can see.
like i said the computer does not control the turbo or super at all. the computer has nothing to do with what the turbo does. there are no electronic devices on a turbo. yes you do have to at least have a chip burned so the computer can add more fuel when it sees boost.
