well i did my compression test today and got 160-175 is that ok? want to put a low 230's cam and spray 100-150 dry. so i go a head and get the cam/spray or should i save for a short block

 

any one?

 

I just did my 01Z LS6 and all the cylinders came out about 180 to 184. The car seems to run strong so I think we're both probably OK. Did you open the throttle when you checked each cylinder? It's supposed to be the correct way to do it.

 

looks fine to me, i did mine came out to 175-180 on all 8 cylanders.

 

hrmm..thats slightly low...not to low but a good average number u want to see is 180-190 but i dont think thats to bad is it high mileage?

 

99,000

 

thats fine. Mine has 10300 and I ran it a couple days ago. It was 174-182

 

Another important thing about compression is that all the numbers are pretty close to one another. Having one at 170 and then one at 150 and scattered around is not really a good thing either. But 170 is fine

 

well I ordered my crane spring compressor and melling oil pump from thunder, and was gonna order the cam package from texas speed but, I got wind of a new version of the cam I was looking in to but now im gonna wait till they release more info

 

i think you should be ok. like mentioned above its just showing signs of wear.they are all close to the same number so thats a good thing

 

i have heard that nitrous likes somewhat worn rings i dont remember why but the guy who said it knew what he was talking about.

 

worn rings or rings with a large gap...same difference. but i really don't think it makes a difference unless you are up in th 250+ shot range because the rings won't inflate enough with a lesser shot to merit using them.

 

compression test wont always tell you everything, i would do a cylinder leak and a power balance test...

 

170 is ok as long as it is consistent between the cylinders. Liek stated above the leakdown test will tell you exactly where any compression loss is coming from because it could be worn valves instead of a worn bottom end.

 

1100 miles on my 408. Compression and leak down test this weekend. 185-190psi. Yours sound real good for the miles. Just do some leak down test to make sure for peace of mind.....
