how high can a miata boost
How high can a stock miata boost ?
|
Plenty of us run approx. 15 psi safely on stock internals, by using aftermarket engine computers, premium gas, constantly monitoring AFR, etc.
Few people dare exceed that much without built motors. But I'm sure other people here will post replies with more detailed answers, and/or flames for asking such a dumb question without searching first. Either way I look forward to reading them. |

OP, you're going to get some "colorful" responses, don't take it personally and use the search function. There have been lots of posts on this subject. |

Wait, stock Miatas don't have turbos. |
With the right engine management you are good to 15/16psi on stock internals in my experience. I ran those values on a stock 1.6L FM2, then later with headwork, TEC3r, WI and a GT2860RS (0.86AR) for 60k miles with no problem. During that time the engine power went from 230bhp to 280bhp or so with the later additions. Torque (and rpm) is probably a better measure of how far you can go on stock internals though.

Why would a stock miata be boosted? What generation are we talking here?

Greetings, yajkenji. As you've no doubt noticed by now, some questions get asked so often around here that the locals tire of them.
Short answer: there are many, many variables other than just boost pressure which influence how much the motor will stand up to before you break it. Engine management, charge cooling, state of tune, turbo size / efficiency, mechanical empathy, phase of the moon, etc. Some folks are putting down 250 HP on stock internals. Others have cracked pistons and bent rods below 200. |

*facepalm*
How much boost on a gt2554 or on a gt3071? There's a huge difference... |

While the apostrophe is generally used to create the possessive construct of a noun (including indefinite pronouns), it is not used to indicate possession in the case of a personal pronoun such as yours, his, hers, ours, its, theirs, and whose. The only situation in which an apostrophe is used with "it" is to form contractions such as "it is" and "it has." |
You know... when those mini Asian chicks started singing... It kind of freaked me out.
I'm scared of clowns too. Just so you know. |

It is a common misconception that the use of the apostrophe is appropriate in the possessive form of the word "it."
