No cats on the car at all, no mufflers either, just two resonators.1) No leaks in charge pipes.
2) WG actuators are holding WG's closed.
3) Turbos are spinning.
4) Still no boost.
5) I'd be looking at clogged cats or restricted exhaust.
That's pretty much my assumption as well at this point. The WG's are brand new and the turbo's freshly rebuilt, it's literally the only thing that changed after the original turbo's let go. I'll be sending the turbo's and WG's back to Canada (CR Performance) for testing ($80 one way shipping) once I get the second turbo out this weekend. They have to go through customs as well, so this long process will continue to be even longer.Ive had major boost leaks and still made 8-10 psi. Even running without my custom blow off valve on before the throttle plate. I was still making 7 psi with a 1.5” hole in the pipe. Even with the linkages took off the turbos. The ecm cant tell it to do nutin. As long as the motor is forcing exhaust into the turbine, it would spool up.
I hate to think it but those turbos dont seem to be making any boost. The turbine can spin all day. Dont mean its compressing air.
Thats crazy, i think everything you tried already put the car out the question. You are running the turbos entirely mechanical and its not making boost.
You know, i bet the wastegate valve is not sealing inside the turbo and pressure it just going through it even when its shut. Ive seen that happen before on another vehicle. Weird how it could be both turbos.
Well if you disconnect the wastegate linkage. And your exhaust works. Ecm and hoses dont matter then. If it dont make boost then the turbos are bad. Either the wastegate valve or compressors. They are simple
They spin freely, aren't rubbing, only have about .005 or less of radial play. I've thought about the chance of someone new at CR performance assembling them, believe me I've thought of every possible scenario at this point. I'm going to send them back for them to inspect and test.Along the lines of @yaycandy, have you tested the turbos themselves in any way? Can you confirm they are not bad? Any chance a newbie at CR rebuilt them wrong? Can you check things like are the turbines actually spinning, are they tight on the shaft, are the seals good, etc?
front turbo shaft broke in half, impeller was sitting in the hose upon disassembly. Rear turbo impeller was rubbing housing and shaft was very loose.Why/how were your original turbos bad?

I could not imagine..... seriously if they weren't as expensive as they are, why if they bench test them, they didn't find it. I would be driving there myself personally.front turbo shaft broke in half, impeller was sitting in the hose upon disassembly. Rear turbo impeller was rubbing housing and shaft was very loose.
So I purchased the car with the tune that ran for about 1.5 years before this happened. The previous owner rebuilt them with the CR Performance billet wheel rebuild kit approximately 2 months before I bought it. Not sure if he did something wrong or if they just didn't last, but to answer your question, no, the new rebuilt/upgraded turbo's have never produced boost since installation. I contacted the tuner from Unleashed and gave him the serial numbers, strategies, etc and told him what I was doing. He assured me the tune I currently had would be suffice unless I started adding fuel pump upgrades, in which I would need a new tune for.@usmc363 just noodling here - was going through your posts - when you installed the new turbos that came back, did they ever run? I am curious why parts broke etc. Since I havent performed a turbo replacement, I know when you get new turbos you need to re-tune and immediately to avoid damaging things, however you always had zero boost, and never heard the mechanical failure when it happened?
Your whole event is very strange.
