Hi, just got my compression test done today and i got these results. I have no idea how to interpret them. Couldnt do cylinder 4 since the guy couldnt pull the lead off. Car has a ported and polished head.

Are these good?

 

Oh BTW i dont think that it was done with WOT. If that makes a difference.

 

lol.. yea thats great.

 

Yeah they are fine but you really want to know that fourth one! You know your compression results are always good as long as your #'s remain consistant . Basing your answering off of somebody else's #'s is a bad idea b/c there can be error, whether mechanical or just not used properly. Consistancy is key though!

 

That chart is pretty neat...I've never seen one like that before.

The first three appear to be almost too consistent. That is, if I'm reading the chart correctly.

 

Thanks for the help guys. I was a bit comcerned they look a bit low in comparison with other results i have seen. Will get the last cylinder done when i pull off the freakn lead.
