tial wastegate question??
tial wastegate question?? im running a tial 44mm wastegate on my setup but im wondering where to hook up the top and side port on it.ive done some looking around and cant find a good answer.ive been told to hook the side port right to my distribution block and the top to my mbc then to the distribution block? this doesnt seem right to me but could be wrong... let me know any help thanks
ok so someone please help me out.ive been seeing also that they say to leave t\he top open and only hook up the side port to somewhere in the charge pipe and put mbc in that line and not off the vaccum block at all.y is it i see alot of them hooking it to a vaccum block?

I have a "pressure" line (before throttle body/carb) that runs into the manual boost controller, an then into the bottom of the wastegate. that's it.
also, I put a banjo bolt of the top of the BOV, just to help keep water/dust out.
I'll run down and take a picture for you in a few.

its hard for me to tell in them pictures but thanks.and that diagram for the boost pressure side of man. where would i run that to my compressor side on my turbo doesnt have a fitting off it?would it hurt it if off the tee i hook it to my distribution block?also bc i want to mount the controller in the cabin how bad is it gonna affect it with all the long hose?
i dont see why not, there are many threads of using that source or the compressor housing for the wastegate. Me personally, ill be running EVERYTHING off the vacuum block, except my wastegate, my wastegate side port will be installed as pictured, but T'd off to the compressor housing

How you plumb it is very dependant on the boost pressure you intend to be running, relative to base spring pressure.
Blow into the bottom port for lower pressures. If you cannot achieve enough boost doing this, then adding a reference to the top port wil help, although may increase your lowest base setting.
And if you needs lots of boost then you can simply blow into the top port only to keep the w/g shut.. I doubt many LS builds would need to go that far though.
For starters, blowing into the bottom port only is safest. If it doesnt work for you then look to other methods.

Also, I wouldnt connect the supply for the MBC to any port where there are important items connected too.
As this port will now vent some air, it can affect readings. I would only ever connected the boost control source to a dedicated port.
