STS 370Z Single Turbo System

Even on a regular turbocharged car is not too safe to have cats on. I've heard some stories like the cats material getting sucked into the turbo and destroying it. Some particles even made past that and damaged the engine.

Just things I heard about having cats on for turbo cars.

How exactly would the catalytic converter components get "sucked through" the turbo into the engine?

With RMT, cats are definitely an unnecessary risk to the turbo, though, no question there.

honestly if anyone knows a thing or two it's red

Honestly if you know anything about cars or hell even have common sense, cats getting sucked into the engine can't physically happen.

Isamu

dude, I have seen some pretty outrageous shit happen.. but never seen a cat get sucked into an engine...
I was just sayin, Red knows his stuff, for the people in question

Do not buy from STS turbo they take months to finish their bolt on kits on any car it took them 6 months to put on my turbo kit on my car and they wanted full payment within 2 weeks i waited half a year for their basic kit!!! And they would not give me discount is costed over $14k every week after the first month i constantly contacted them and they kept saying the car will be done next week they kept saying for 6 months!!! WTF these guys are lazy,slow and dont give a sh!t about their customers. I want to know can i sue them for having my car for so long and charging me more then their estimation on the price and telling me it would be done in 3 weeks and they kept telling me it would be done the next week for 6 months.


im sorry guys my grammar sucks im just really mad at them.

fuct

do you have anything in writting/email?

dastaco

He hasn't posted any proof yet of having his car worked on. Until we see anything legit from him I'd take his word with a grain of salt.

After what said company has done to a few members it doesn't seem that unlikely of STS doing this. The fact they haven't even tried to defend themselves says volumes about them. How much more disgruntled customers do u need to hear from?

You know, I was wondering the same thing, but that topic has been beat to death on this board so I just left it.

I can see it getting sucked into the turbo on a RMT kit but I'm pretty sure it's gonna stop there and not cycle back through the innercooler then into the engine. Maybe it's the "magic bullet" theory for car guys.

Red__Zed

I've actually seen it happen, although almost exclusively on cars with pre-cats that are right on the end of the headers, and only when initiated by core failure



The turbine and the compressor aren't using the same air. I can't imagine chunks of cat hopping between housings

You can look at a picture of a turbo and pretty quickly figure out that core chunks aren't going to wind up in the intake.

blackonorange

Huh? You've seen it happen ? How ? I don't understand how they could get in the engine

Red__Zed

The short explanation is that there is some overlap between intake & exhaust valves opening. There is vacuum in the cylinder, and backwards airflow (backflow) is pretty common, generally sucking some small amount of exhaust gas back into the cylinder. In cases where a cat (again, generally a pre-cat because of their proximity to the exhaust ports) has broken down, you have
A) loose pieces of honeycomb floating around
B) significant increases in backflow

and it becomes technically possible for cat material to flow back into the engine.

blackonorange

When you say pre cat, you mean cat before the header ?
