importwarrior Posted October 10, 2015 Author Report Share Posted October 10, 2015 Fixed 3 of the 4 leaks in the intercooler piping and couplers. Nice *DM chrome OVCP with 2 pin holes in the pipe. Looks like it is in the weld where it bends near the tbody. One coupler leak was bad at max PSi of 18 to 20 and it would leak.Fixed that for now. Bov held with no leaks at all. Still same no boost problem. It seems now we are working ourWay towards the intake manifold. Running out of ideas. Link to comment Share on other sites More sharing options...
StarquestRescue Posted October 10, 2015 Report Share Posted October 10, 2015 What happened when you ran open down pipe? Link to comment Share on other sites More sharing options...
importwarrior Posted October 11, 2015 Author Report Share Posted October 11, 2015 Same 4 PSi. Going over the waste gate tomorrow. Car drives great but boost comes on slow. Stops at 4 PSi. AEM wideband shows 11.0 to 11.5 when floored at the 4 PSi on autometer boost gauge. I'm sure I am missing something. Link to comment Share on other sites More sharing options...
Turbo Cary Posted October 11, 2015 Report Share Posted October 11, 2015 Check your settings in your ecu system. My friend Joe is using a Haltech Sprint 500 to control his quest. Had the same issue. Turned out there was a setting that limited max boost like a fuel cut. It was set at 5 and wouldn't go over. After some small adjustments to double check the external gate and the software I had it boosting 15 psi. Link to comment Share on other sites More sharing options...
importwarrior Posted October 11, 2015 Author Report Share Posted October 11, 2015 Thanks for the help. i will check it out. today i tested all intercooler piping AGAIN fromturbo inlet this time to the OVCP where it connects to the Tbody.fixed the leaks for good now it holds 25 psi no problemfound a blown fuse. still slow to boost to 4PSi :mad: Link to comment Share on other sites More sharing options...
Turbo Cary Posted October 11, 2015 Report Share Posted October 11, 2015 After reading everything over a second time it seems like you have checked every mechanical reason as to why it would not produce boost. Have you tried plugging the line to the wasyegate and "free boosting" it for a second. Yes I know it is dangerous but it could help eliminate the wastegate for sure. If boost climbed past 4 psi with that done you know the wastegate is sticking open with it connected for some odd reason. If not then it would have to be in some fail safe with your ecu software. What specific type of software are you using? Is it just a manual boost controller or do you have access to a electronic one? Link to comment Share on other sites More sharing options...
importwarrior Posted October 12, 2015 Author Report Share Posted October 12, 2015 II believe it is possibly the wastegate. I have ran it with no hose connected tothe wastegate.II hooked the compressor to the wastegateand it moved properly.It stayed open until I released pressure. I am going to recheck the wastegate one more time. Link to comment Share on other sites More sharing options...
slydogg Posted October 12, 2015 Report Share Posted October 12, 2015 there is an ebc in the car wired and ready to go. i would try that also. swap the wastegate for a single port. it has to be a simple fix. Link to comment Share on other sites More sharing options...
importwarrior Posted October 15, 2015 Author Report Share Posted October 15, 2015 RESOLVED !!!well to all the Guys that said to remove the exhaust and run just the down pipe..You are CORRECT. Clogged CAT. We took it to a shop to have them pull the exhaust and run it on the dyno just to test it with no cat or exhaust.once the exhaust was removed and only the down pipe was the only thing on they ran it on the dyno. it spooled really fast.the turbo is larger then the previous turbo TDO5 18G to TD06 20G i didn't want them to boost it more then 10 just to be safe.well once they put it on the dyno they started to test it and instantly let off. it made more then 10 Psi under 3000 RPM.from that short run and they let off at under 3000 rpm it made 150hp and 250 TQ. car needs a tune.i had to turn down the boost controller all the way. it still made 14 Psi at the lowest setting. we didn't really get any dyno results due to a lac of tuning. so to be safe we had them take it off the dyno.didnt have a laptop with tunerstudio with us. this was just a test with no cat. i can't explain how relieved i am now that it is running properly. they are going to remove the CAT. the car is exempt from emissions and the cat is not needed. what a relief.. 1 Link to comment Share on other sites More sharing options...

importwarrior Posted October 16, 2015 Author Report Share Posted October 16, 2015 Even though the clogged CAT was the problem, we found many otherlittle things we would never had found if the car didn't have the bad cat. we found a couple backed out exhaust manifold studs.bad manifold gasketslightly warped manifold, we had it surfaced flata bunch of small leaks in the intercooler piping and couplers.wastegate not swinging smoothly.EGR block off leaking possibly due to blocked CAT causing massive pressure.some loose vac lines that are now zip tied.leaking Boost controller fittings i am sure there are a few other things as well. i just cannot remember at the moment. the inter cooler pressure test was a great help in locating a lot of small leaksthat could have added up to a fairly big leak. Scott is going to pick up his car today. they removed the cat and welded two pin holes on the OVCP.i will report back as soon as i get out of work and talk to Scott and he tells me how she ( Red 86) is running.
