Jhandy Posted May 9, 2015 Share Posted May 9, 2015 Ok guys. Fitted my turbo today td05 hybrid. Anf i cannot for the love or me. Get the thing to boost past 0.7 bar. What could be the problem. I have checked all the usual stuff and everything is fine. Does anyonr have any suggestions. I am running a external wastegate just on spring pressure which is 0.8. And it wont even open that Quote Link to post Share on other sites
daniel_g Posted May 10, 2015 Share Posted May 10, 2015 What ewg is it? I have the same issue and the springs seem to be below their rating.Gonna get an ebc and up the boost that way Quote Link to post Share on other sites
Jhandy Posted May 10, 2015 Author Share Posted May 10, 2015 Its a tial wastegate bud. I had a td04 on it before. And it always opened at 0.8. Im gonna try my avc-r today see what luck i have Quote Link to post Share on other sites
Jhandy Posted May 11, 2015 Author Share Posted May 11, 2015 ok, so yesterday i spent the whole day on the car, took the turbo back off to check it, and its all fine, once i refitted it, i drove it down the road, just with turbo pressure, meaning no vac hoses attached, so the turbo is fine, as i got it round to 1.5 bar and changed gear, so i reffited all the vac hose that goes from the turbo, straight to the bottom the of external wastegate, and vents at the top, and it wont open the wastegate, the turbo will only boost to .75 bar, and wont open the wastegate, so i installed my avc-r, and still wouldnt open it, even adjusting the boost control on ebc wouldnt let it boost no higher, so in the end i tried a bleed valve and i have that set at 1 bar, but its still not opening the ewg, so where is all this excess boost going. anyone have any ideas, as im getting angry with it now Quote Link to post Share on other sites
haggis Posted May 13, 2015 Share Posted May 13, 2015 Try winding in your actuator ? If you for spring set to 0.8 then when you reach close to 0.8 your waste gate is opening and dumping hence your not getting a pressure buildup behind the turbo ? Stronger spring or wind it in?
