DO Ijust unplug the PCV valve or what. When I plug the hose running from the TB will my boost rise?
HEY GUYS I FINALLY GOT THE SUPERCHARGER INSTALLED!!! I have pics

To stop crankcase pressure you can install a PCV valve from a Turbocoupe between your stock PCV and the intake.
The replies you have received have been spot on.
Reread them and make the changes as stated.
BTW....I wouldn't be running it WOT until you have it tuned.
Blowing a head gasket a week after the blower install will suck.
i would just take some 3/8 rubber vac caps, take out the line from the PCV to the intake manifold. plug both ports. this will render your PCV useless. so now we need to find a way for crankcase pressure to exit.
then take the line off that connects the TB and the oil filler neck. plug the TB port with a rubber cap.
now we need to vent the crankcase to atmosphere or have the engine pull on the crankcase a bit to get the vapors and pressure out.
they way i did it was just buy a clamp on breather and put it on my valve covers. its vents the crankcase, its the easier and works great, it solved my crankcase pressure problems.
or you can run a vac line from your oil filler neck, to in front of the blower.
and easy way to do this is buy a brass 3/8 NPT barb with a 3/8 vac nipple on the end (the vortech air shield should have one in it you can use). drill a hole in your powerpipe and use some silicone and thread the nipple into the power pipe. then run the 3/8 line from there to the oil filler neck port. this way the engine will pull on the crankcase even when under boost and will pull out and pressure or vapor and trash also. i ran mine like this before i ran open breathers.
try that and see what happens. also make sure the belt is tight.
but if your still running the car like in the first pic you posted, your pushing boost into the crankcase, boost is going from the TB line to the oill filler neck and that will affect boost levels. i pretty much did the same thing and it made less boost and i couldnt feel it until the higher rpms.
i think your problem lies there. i definatly think you should be making more than 5 psi. IMO its bleeding off somewhere.
How did you run breathers? My valve covers doesnt have a place to run breathers. Also I didnt use the air shield that came with Vortech because the power pipe runs to the inside of the fenderwell where as with the stock Vortech setup it doesnt

i made my own fabricated set of valve covers and put a vent stack on it and i used a clamp on breather that looks like a little air filter. liked stated above you can get a screw in breather cap from K&N
and what i mean about the fitting is you can unscrew it from the black vortech air box and use it on your power pipe.

I have a question about the power pipe hook up I am not sure if I have it hooked up right. I am still using the elbow that has the by-pass hole tapped into the bottom of it and the I have the power pipe hooked into that . Is that right? and also there is I guess you would call it a barb sticking out of the power pipe,but it is inside the fenderwell and and near the MAF and it is really big so I just capped it off
see your power pipe looks alot different than mine. Mine has a port about the size of a quarter and thats it. It has no place to screw in a by-pass valve. See if you can find some pics for a PP for a Vortech S-trim. If anyone has a good pic of the Vortech UPR power pipe please post so I know if I hooked it up right. I might be missing out on some boost
sounds like you put it on backwards or something. that 1 inch port is for the bypass.
when properly installed it should point downward, i duno why, it makes it harder to route the bypass lines but thats how upr made it.
you should have got a huge rubber 90* elbow that will clamp on to the SC inlet, and the other end should have a huge part to clamp to the powerpipe (end with the port on it) the pipe runs through the fender and turns towards the front of the car and downward a bit, you have the huge sort of flex coupler that goes on the end of the power pipe and then the maf and filter goes on the other side.
heres some older pics of mine installed, excuse the dirtyness
i drilled a hole and threaded in that barb and ran the line to oil filler neck, this was before i ran open breathers, once i did thati just capped that off. in case you wondered
this was also before u ran a bypass setup. my bypass valve setup isnt anything like vortech made it, i bought all the parts and drilled a hole in my plastic inlet tube. and ran 1" heater hose. with the upr pipe it was hard to get a line to make such a bend in a small area to clamp to the port on the powerpipe. so i had to weld up a little turn around pipe to use.
duno if the pics will help but maybe it will
yeah I did put it on backwards. But I dont know how I would get it to work. The port is like on the side and the bypass valve hole on the stock Vortech pipe is on the bottom. This will be hard to get to work. It is so cramped in there. Maybe thats why I didnt see any difference as far as boost goes.
well as long as the bypass was working it doesnt matter. some people see more boost gains then other, and the power pipe isnt really a big difference.
did you ever get around to messing with the PCV stuff?
yeah kinda. The pipe that runs from the TB to the oil filler neck was blown off LOL. The pics that I took was before I ran the car. When I went to take the hose off. The boost I guess blew it off lol so thats not there no more. I did unplug the PCV and put a cap on the intake side and should I cap the pcv valve itself and leave it in there? After I do that I think I should prolly get that screw in breather right for the oil filler neck? Damn I wished you lived near me so you can help me hook it up
should I run a hose from the power pipe to the oil filler neck or buy a screw on filter for the oil filler neck
So thats all I have to do to vent the crankcase properly? I thought you need vacuum to draw out pressure and such?
it will vent just fine, putting the breather cap on it will allow atomspheric pressure into the crankcase. and as long as its sharing the same air as the outside its just fine.
plus the blower will cause small amounts of blow-by past the rings regardless so the crankcase is going to try and pressurize (if it was sealed it would pressurize, either pushing the dipstick out of blowing out gaskets) but since the air can escape it will leave the crankcase and not cause a pressure
