What is a good safe PSI on a turbo? I hear if you go too much, the apex seals are at risk.. Id like to get a good 4 years out of my engine.. Thanks!

 

In order to get your 4 year mark, you will need to keep the PSI at less than 0. If you increase the PSI to 0 or higher, then you must garage it 6 out of every 7 days of each week across those 4 years.



Note: I'm serious. Every tiny little bit of boost increase on our engines is a DIRECT drop in engine life expectancy. Also, note that "4 years" of being a garage queen is drastically different life for an engine than "4 years" of doing 150 miles per day commuting. Mileage is far more important for engine life than time, and you haven't provided that.


Basically, if you boost your engine, taking your crazy slow time doing everything exactly right, starting with a complete engine rebuilt, with a budget of $10k+, then you can probably get at least 20,000 miles out of the engine. Every shortcut you take less than this will decrease your expected lifespan. There is a thread going right now about a guy that made it a couple miles...



This isn't a piston engine. There is no "safe" PSI when you can blown your engine staying naturally aspirated...

 

turbos don't have apex seals...

 

Hmm...How cool would it be to have a turbo with a tiny little rotor in there in stead of a turbine. It wouldn't do a damn thing but at least you could say its there.

 

I modded my seatbelts, so that the pretensioners run on little rotary motors....

 

One billion PSI.

 

for real though. There is no magic number for any engine, in any car. Some come close, but rarely and they usually come boosted from the factory when it happens.

Sit down and do some research OP. By research, i mean read until your eyes bleed, then read some more. After you have a pretty decent understanding of how rotaries work, how the renesis is different, how turbo charging works, how turbo charging a renesis is different, and then how PSI actually doesn't mean as much as air flow does, then you should ask questions to clarify the missing pieces.

 

Who the hell would be dumb enough to turbo their RX8?

 

Posting your questions in the wrong forum area is not safe for getting correct answers ...

 

Especially when they're this broad.
