Hemi Posted October 25, 2008 Share Posted October 25, 2008 i doubt itd be bent , just looks weird lol . you could if you had a boost guage . while we are on that why do you want one of them ?? , for when you get a controller? Quote Link to comment Share on other sites More sharing options...
WildPlumDx Posted October 25, 2008 Author Share Posted October 25, 2008 as for the boost gauge can i tap into that egr plate ? the gold looking plate in the center of the intake manifold? yup i have everything i need pyrometer boost gauge and controller, one guy had his pajero up to 25psi been running for 6 months, i dont wanna run that high anyway 15psi would be nice, plus once i blow it up i'd like to put a 3.8 commy engine in it Quote Link to comment Share on other sites More sharing options...

WildPlumDx Posted October 25, 2008 Author Share Posted October 25, 2008 oooh btw is there anyway i can test my wastegate too see if its working right ? Quote Link to comment Share on other sites More sharing options...
Hemi Posted October 25, 2008 Share Posted October 25, 2008 boost gauge would be the easiet way man ,if its running at the manufactor spec boost then there nothing wrong . usually know when a wastegate fails cos all of a sudden you have more power and the turbo will start screaming its nuts off Quote Link to comment Share on other sites More sharing options...
slipsittin Posted October 25, 2008 Share Posted October 25, 2008 If you want to get technical about the waste gate you need a gauge, regulator and compressed air to move the wastegate arm. The pressure applied at the given measurement of wastegate by the manufactor is the spec they work off. But as MONGOL says if the guage you are hooking up reads right thats as close as you need to know. We are all here to help man, and the best thing is we are all from different walks of life so we all learn from each other Corey Quote Link to comment Share on other sites More sharing options...
Jase Posted October 25, 2008 Share Posted October 25, 2008 a cheeky way to get a little more boost is to put a couple of 2mm washers under the mounts of the wastegate solenoid making the gate open less , worked really well in my 2.4 surf as the waste gate was originally coked up so we spaced it up to get it to seal properly and found it gave it a shitload more grunt, found the info on an aus 4wd forum Quote Link to comment Share on other sites More sharing options...
mitsi101 Posted February 9, 2014 Share Posted February 9, 2014 I did this in my pajero and it will only go up up 13 psi .how do I get more boost Quote Link to comment Share on other sites More sharing options...
DriveBy Posted February 9, 2014 Share Posted February 9, 2014 Whoa thread from the dead. Get a boost tap and tee it in line with the tubing that goes to the wastgate actuator (actuator is the metal cylinder thing). Then you can adjust how much air you bleed off (and therefore how much the actuator sees) so that the actuator opens the wastegate at a higher boost pressure.

Yowzer Posted February 9, 2014 Share Posted February 9, 2014 Disconnect the wastegate. Run all the boosts. 4 Quote Link to comment Share on other sites More sharing options...
Jase Posted February 9, 2014 Share Posted February 9, 2014 yeah does wildplumdx still hang about I'd like to borrow that timing gauge for my ve pumps, you want more boost add more fuel chap, pay to get an egt gauge first though Quote Link to comment Share on other sites More sharing options...
Yowzer Posted February 9, 2014 Share Posted February 9, 2014 Check valves work better than bleed valves, however they are generally more expensive. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted February 9, 2014 Share Posted February 9, 2014 Bleed valves are OK when you are not driving a huge diaphragm area - all good for an internal gate (generally speaking) but not so great for an external gate which requires more air. I run a bleed tap at 18psi on my triton ute for a bit extra boosts, it doesn't seem to overboost at all. pre-loading of wastegate can be a bit hit an miss, i would not suggest using this method if your actuator has a reasonably short stroke, taking 2 or 3 mm out of an actuator which only has 9-10mm stroke is not ideal and may lead to boost spiking. With the price of a boost tap these days i personally wouldn't run any more preload than just enough to firmly seat the flapper. Quote Link to comment Share on other sites More sharing options...
Raizer Posted February 10, 2014 Share Posted February 10, 2014 yeah does wildplumdx still hang about I'd like to borrow that timing gauge for my ve pumps, "Last Active 04 Feb 2008" Would take that as a no lol Quote Link to comment Share on other sites More sharing options...
kpr Posted February 10, 2014 Share Posted February 10, 2014 adding an external spring, from the body of the actuator to the arm, is a good/cheap way to raise the boost. if you have a spring and a welder hanging about. Quote Link to comment Share on other sites More sharing options...
jessemk2 Posted February 10, 2014 Share Posted February 10, 2014 I did this in my pajero and it will only go up up 13 psi .how do I get more boost My money is on your diesel pump is restricting boost,bleeding air and spacing wastegate can only do so much on a diesel. You need to wind your diesel pump up Quote Link to comment Share on other sites More sharing options...
UTERUS Posted February 10, 2014 Share Posted February 10, 2014 wat The pump has no way to restrict boost, turbo ain't gonna give any fucks how much fuel is going in there. Lots of boost is fine for diesel, the more the merrier when it comes to mashing air in there. Adjust boost to where it's getting out of the maps efficiency, whack an EGT gauge on there and adjust fuel to suit. Quote Link to comment Share on other sites More sharing options...
Yowzer Posted February 10, 2014 Share Posted February 10, 2014 / freeboost like a boss Quote Link to comment Share on other sites More sharing options...
Yowzer Posted February 10, 2014 Share Posted February 10, 2014 Although he could be right, if you try to increase boost while keeping stock fueling then it's only gonna spool as much as the exhaust will allow, which is 3/5ths of fuck all.
