Hello,

As tittle says, what would be the typical cylinder compression in these 3.3L turbo engines (stock in good condition assuming). Not looking for the leak down test at this moment.

Thanks

I just did both compression and leak down before dropping my motor to do more mods.
The compression tester is a new IEC .
I do have small reliefs cut in my pistons for a high lift cam.
I have 10 k miles on a full rebuild
I measured 150 psi on every clyinder
the leak down was less than 1% on every cylinder

Thanks! I got 50 psi for all the cylinders which seemed too funny! Is a new Snapon compression gauge. I will just have to test the gauge in another vehicle and see if is defective or what.
