ollie ryan Posted August 14, 2011 Posted August 14, 2011 got a my turbo setup on and gone for drive and i have no boost at all, im not runnning any form of boost controller and running straight off the spring, do i need any vac lines coming off the wastegate? Quote
shorty Posted August 14, 2011 Posted August 14, 2011 lil vac pip on turbo compressor housing to the bottom port on ex waste gate if that dont work post a pic of the setup and we can go from there dude Quote
ollie ryan Posted August 14, 2011 Author Posted August 14, 2011 okay mate, at the moment i have no vac lines on or off the turbo or wastegate Quote
shorty Posted August 14, 2011 Posted August 14, 2011 thats you problem then id say bud will run off wastegate spring then. Quote
ollie ryan Posted August 14, 2011 Author Posted August 14, 2011 yeah i just want to run off the spring tho as i have no boost control Quote
TrisK Posted August 15, 2011 Posted August 15, 2011 yeah, so vac goes from the turbo (where it normally goes to your actuator) to the side port on the external wastegate.then when you have boost control, goes from the other port to the solenoid, then to the inlet manifold. then the solenoid plugs electronically to the controller in the cabin Quote
ollie ryan Posted August 15, 2011 Author Posted August 15, 2011 There is no where on the turbo for a vac line to go tho Quote
RobSR Posted August 15, 2011 Posted August 15, 2011 take it off any boost source then, so inlet etc,... not ideal, but itll work... normally if you have no vac lines, you have unlimited boost :S let us know how you get on..you getting any screamer pipe noise? Quote
SiCaln Posted August 15, 2011 Posted August 15, 2011 LinkyAs you can see it has no vacuum connection on the tubby, nor did I ever use one, just ran it off the 0.8 bar spring Quote
ollie ryan Posted August 15, 2011 Author Posted August 15, 2011 I have no boost at all and nothing coming out the screamer pipe Quote
RobSR Posted August 15, 2011 Posted August 15, 2011 right ok..well, if your wastegate has no vac lines on it what so ever, it means that you could run unlimited boost, seeing as theres no vac source opening the wastegate at the correct time, so id think it would be something turbo side... 100% you have no boost leaks? no IC pips blown off? Quote
SiCaln Posted August 15, 2011 Posted August 15, 2011 yea that's what im thinking, because surely it would be trying to spool even if not making it Quote
TrisK Posted August 15, 2011 Posted August 15, 2011 run a vac line from the inlet to this port on the wastegateThe vac line should come from the turbo, but if you dont have one then just take one from the inlet or any other source Quote
ollie ryan Posted August 15, 2011 Author Posted August 15, 2011 I will check for boost leaks, but silcan ran this turbo before me without any vac lines on the wastegate and he had no boost problem Quote
SiCaln Posted August 15, 2011 Posted August 15, 2011 nope none at all, i'm also running my current kit like it Quote
RobSR Posted August 15, 2011 Posted August 15, 2011 what so no vac lines on the WG atal?! must have a pretty soft spring and its blowing it open then! that is strangeee... Quote
ollie ryan Posted August 15, 2011 Author Posted August 15, 2011 i will try7 it once more, if it doesnt work will run a line from the inlet mani Quote
SiCaln Posted August 16, 2011 Posted August 16, 2011 other thought I had, have u checked that the tial is tightened properly all the way round? Think it was but could explain a leak Quote
ollie ryan Posted August 16, 2011 Author Posted August 16, 2011 I didn't check that, will try that tonight aswell Quote
rorenapier Posted August 16, 2011 Posted August 16, 2011 throw a pic up, from what im reading there is something seriously wrong.There is no way it can hold a constant pressure if there is no vac lines to it. If anything (as stated above) you would get unlimited ammounts of pressure.You have the tial on the correct way round? Quote
RobSR Posted August 16, 2011 Posted August 16, 2011 My thoughts exactly...Surely if the gate was on the wrong way round..you'd still have unlimited boost as it woukld be holding it closed? Quote
BenV Posted August 16, 2011 Posted August 16, 2011 is the ring still in the tial wastegate? ive herd of a few that are missing them and have problems boosting Quote
rorenapier Posted August 16, 2011 Posted August 16, 2011 Indeed, but im ruling out any other issues that could be problems. My thoughts exactly...Surely if the gate was on the wrong way round..you'd still have unlimited boost as it woukld be holding it closed? Quote
