If you know how to wastegate a procharger come in. I'm getting ready to buy a Prochager setup for my car. I have been looking for info on using a wastegate to control/Adj. boost on a procharger. Anyone on here done that before? I know it can be done but have no clue how to do it.

Id think youd place it as if it were a BOV. So it needs to be on the compressef side of the charge pipe.
And youll just plum it as if it were a raguler wastgate.
So manifold pressure to the bottom port and you boost contoler to the top

W/G before the IC..
just pulley down the blower. if its a D1, go with like a 3.8" pulley. Itll spin the blower quickly in the lower rpm range but the WG will crack open limiting ur boost. You could also do a eboost 2 controller to manage it better. id run a meth kit for some safety also if ur on a stock bottom.

Im not saying this to be an ***, but search. I just searched "wastegate on supercharger" and found probably 10 threads, i was actually looking for a specific thread from a few years ago that had TONS of info in, i remember posting the link a few times.
Here is one thread i think had some good info. Serious though, their was on thread that went on for like 15 pages with people who have done it with great results. I seem to remember a guy with a corvette posting pictures of his wastegate and using like an eboost to control it.

If your able to max the blower out on ur motor without any issues, this wont benefit you at all. this is for guys with stock bottoms wanting the most performance they can get out of 8-10psi... You spin the blower to its max, which would usually creat some high boost numbers, and you limit the boost pressure to the desired 8-10 with a wastegate. it allows some bottom end torque to come into play with the blower coming alive so quickly on the car.
The reason to do this is to ramp the power in on the launch when you are making more power than the track can handle.

That is actually the exact opposite of why they came up with it. And BTW, anyone using it for this purpose is ignorant as they are working the motor at max resistance without getting max boost.

Explain your statement in bold. No matter what a wastgated centrifugal setup was "originally" designed for makes no difference. Pulleying down and bleeding off boost works great to make a fun torquey car. Only downside is the increase in air temp because of spinning the blower harder.

As you change the size of the pulley you increase/decrease the drag on the motor. When the blower makes more boost, it is creating more parasitic drag and requires more tension on the belt. So you get more side load on the crank and the additional parasitic drag is not being compensated for by any additional boost (because you are bleeding it off up top If I understood your statement correctly). Plus the increase in air temp. It is wasting a tremendous amount of energy in a system that is already not very efficient. The correct solution to the problem you are trying to correct is the proper torque converter with the desired boost level achieved by way of pulley ratio.
I have aster bracket tension is set by a spring tensioner. The amount of energy it takes to spin a d1sc at max boost is nothing like spinning the bigger f series. I think if your spraying alot of meth like I am inlet temps dont matter as much. when I had 4.25 pulley on without wastegate it was peaking at 11psi. My inlet temps were so low I couldnt even tune for meth failure using inlet temp. I really think for a d1 stock bottom end running a wastgate is the way to go.
