compression test #'s
just wondering what you guys are getting with your compression test #'s. just finished mine's and here's the results.
270 270 265 265
not too shabby for a motor with 100k+.
setup: JDM h22a, m2b4, AEM CAI, dented up Apex N-1 catback, removed balancer belt.
side note: did a compression check on my lil bro's d15b7(dx motor) and he got:
215 210 210 215

Re: compression test #'s (Honda Sport)
depends how you compression test it, but it doesn't sound like your doing it properly, turn the car on get to operating temperature, hit WOT and crank 3 times....
Cold compression testing will always give really high false numbers

it was at operating temp with all plugs pulled out at WOT. I've done this a few times so I think I know what I'm doin. plus if it was cold, I would think the numbers would be lower considering the rings haven't expanded yet. if you guys don't believe me, I can get video if you want. 
so anybody have any numbers they wanna share?
