Please DO NOT Post In The General Section
From this point on until otherwise briefed, posting in the general section of Performance Tech is prohibited. The only thing to remain here will be the stickies. We would just delete this section, but that would cause unintended results.
The majority of the threads created can appropriately be placed in one of the Performance Tech sub-forums or Technical; and the posting of them here is detrimental to the activity of said forums. If you have any questions about where you need to place your thread PM me or one of the other mods.
For the most part you all have caught on without this post, but there have been a few habitual offenders that forced me to say this.
Everyone will get a couple of warnings from here on out, after that I just start deleting threads.
Again if you have any questions, PM me or one of the other mods.

You want to be above 140 (160+ H23, 180+ H22), and you want it to be even; as in no more then 15 PSI difference between any of themOriginally posted by DoctorCipher...the beginner forum was created to provide a place for all the stupid ass questions to pile up and fester, kind of like huge globs of mayonnaise left in the sun for weeks at a time.

A motor will run with 100 PSI compression, but it won't make much power, and probably burn a lot of oil (or have a lot of gas deposits in the oil)Originally posted by DoctorCipher...the beginner forum was created to provide a place for all the stupid ass questions to pile up and fester, kind of like huge globs of mayonnaise left in the sun for weeks at a time.

Okay, I have a quick question: Is it something I'm missing but why are all you guys' compression #'s so high? Is it b/c you did your checks while being turbo'd? You wouldn't see any boost while checking compression or would you (thus upping the comp. #'s)?
Originally posted by HondaFan81Helms manual info for F22ax motors:
178 psi Nominal
135 psi Minimal
28 psi Maximum variation
hurricanedsm-185psi on all 4 @ 118K (stock)
prodigymb-180psi
midnite racer x-180psi @ 184K
92HondaEX-190-195psi
Why are these #'s so high being that 178psi is standard? These 4^ are all using the F22aX block w/ stock compression (I believe). I'm sorry for the noobish question
