skamaniac Posted October 21, 2008 Share Posted October 21, 2008 So I just got done installing my new Manual boost controller and went for the test drive, and it was not boosting, then there was a fairly large spike and then back to no boost... I will detail my hookup and maybe someone can show me my error... 1981 280ZXT Hallman Ball&Spring Controller I hooked the outlet of the boost controller to the wastegate. There are two vacuum lines, one from the intake and one from the turbo that meet at a "T" that normally feed into the wastegate. I hooked the inlet of the boost controller after this "T". Does this sound correct? Am I suppose to cap one of these lines? Any help would be greatly appreciated! Aaron Quote Link to comment Share on other sites More sharing options...
roger.svoboda Posted October 23, 2008 Share Posted October 23, 2008 On my 81 I just cut the hose going to the waste gate and put the boost controller in there. outlet to the waste gate inlet. pressure from the volute to the boost controller. you must adjust the boost controller to get correct boost. Be sure you don't kink hose. Son did that on the z31 and he got like 25 psi boost cause the boost controller never saw boost pressure.

nismopick Posted October 23, 2008 Share Posted October 23, 2008 MBC = FTL. Especially cheap ebay ones. What kind are you using and where did you get it? You should be able to easily install it inline w/ the hose going to the waste gate actuator. You don't cut or cap anything, just add a length of hose on the now lacking side.

240z!!! Posted October 23, 2008 Share Posted October 23, 2008 are u sure you have it facing the right direction....it should have and arrow pointing toward flow on it...if you dont have it the right way than it wont let any air pass through it b/c it has an air restrictor in it...air can only go 1 way Quote Link to comment Share on other sites More sharing options...
skamaniac Posted October 23, 2008 Author Share Posted October 23, 2008 It is definitely not a cheapy eBay one. This is top of the line hallman ball & spring... I am pretty much at a loss now.. I hooked up the controller after the Y connector in line before the wastegate and when I take the car out, it is just running really bad. It does not seem to want to boost at all. It idles decent but when you accelerate, it is slightly hesitant to change gears and it just really doesn't seem to boost at all... Only things I can think of.. Does it matter what position the controller is in? I have mine laying flat not standing upright?? Or do you have to add a certain amount of boost from the controller? I had mine backed off to where there would probably be very little if any?? Any input here will help. This is really starting to drive me nuts. This should be an easy install and it is causing headaches.. As far as flow direction, the instructions say the bottom fitting is the air in from the compressor and the side fitting is the air out to the wastegate. That is the way I have it hooked up right now... Quote Link to comment Share on other sites More sharing options...
240z!!! Posted October 23, 2008 Share Posted October 23, 2008 yes after you install the controller it mesures the boost....for every click that you turn it is 1 lbs. if you have it closed you wont get any boost at all...close it all the way then raise it to 6 lbs(with the boost controller) then drive the car and see if that does anything Quote Link to comment Share on other sites More sharing options...
