Not to be a bitch or anything, but nsfw tag before you post a photo like that PLEASE.

Thanks for the NSFW tag jackass

Damn it people fine!

There's people that have blown their engines at 0psi then there's people like leatherface running 21psi just fine, I run 17psi and there's plenty of more people too.

I've learn no to click on any of Leatherface's links if I anywhere but home.

Since I have a similar question, how many miles were on the engine before you started running 17psi, and how many have you put on since?
The problem is we need to specify what it means to "blow." If you mean fail by any method - then yes. It is possible that by adding extra load to an engine you can cause it to fail sooner than it would have from normal load conditions. If you mean fail catastrophically - like as in send a rod through the side of the block - then not usually. I have seen a stock motor fail on break-in at 0psi because someone failed to torque a bottom end bearing cap. I have also seen the same thing happen due to a bad tune. Basically in both situations, unless something is ready to fail on its own or your tune is messed up, you are pretty safe. The more you are asking your engine to do, the stronger/fresher it needs to be. |

I am guessing what you are asking essentially is if high milage motors are more dangerous to add force induction to, and if they survive long in that condition.

Basically thats it for me, as i'm still in the decision making process as to what miata I buy, and with what engine in what shape. Luckily I telecommute, so no need for a daily driver. So I doubt i'd put more than 2-3k miles on per year, and really i'm probably only looking at trying to reach the 180hp or so mark (as i'm looking for 5-6 second 0-60 times). So seems like a 6-8psi boost should easily hit that, and from the sounds of it not hugely reduce engine lifespan.
I turbocharged the Miata when it was my DD for a 200mi/day commute. 10-12psi, 180-200whp, and ragged on it for over a year. It's all in the tune. |
Also a quick comment- the engine is only seeing higher stress when you are in the boost. A majority of the time your engine is just purring along like stock.
