Compression results after rebuild

[matt98eclipse]

Today I did a compression test today. My results were pretty good I think. The rebuilt has only 127 miles on it. My question is what do u guys think about the numbers and how many more miles should I go before I can do 8 pounds of boost? Right now I have been boosting around 3 pounds.

1,200
2,180
3,180
4,180

Keep in mind all I did was changed rod bearings and put new rings in motor.

Above 150 lbs is great unless I'm misinformed. As far as #1 being so much higher, I dunno.

Looks pretty good, it's not too out of the ordinary to have one cylinder with slightly higer compression than the others.

Ring seating is a highly debated topic. The first 20-40 miles are critical in the ring seating process. So with 127miles, your rings are as seated as they'll get. However, over time your #1 cylinder might drop to be closer to the rest.

Let it sit for now. Let it go another 1000 miles before you turn the boost up. Go ahead and change the oil to remove crap from the fresh rebuild and after 500 miles check it out again.

Thanxs guys this weekend I am gonna change the oil and see how things go from there. So you guys are saying that pretty much the rings have already seated all the way?
