Compression and Leak down results

[Clockmike]

I just had a mechanic do a compression test and leak down test on a 911T 2.2 liter engine with “upgraded cams”. Could I get some feedback on these results?
Compression ranged from 105-115.
Leak down was between 1 & 3 percent on all 6 cylinders.
Engine has 31,000 actual miles.
Would you conclude that the motor is in good health?
I’m concerned because it seems the compression is lower than the 120psi minimum I’ve read about.

The compression ratio in a T engine was spec’d for mild cams. When upgrading cams, the compression ratio is typically raised to keep the dynamic CR up.
I think your motor is fine based on the leak down numbers. I’d like to see the compression test numbers be a little more consistent, but the low numbers are likely due the the cam specs plus the low CR of the T pistons.

Did they open the throttles while doing the compression test? It makes a difference on individual throttle apps like carbs, mfi, etc.

related question for mr. walker. I've always had my leak downs done at 90-100psi on the compressor side.
On the auction sites I see tests being don at 30psi, is this really enough pressure to run a valid test?
