Prior to me putting my car into its supercharger makeover i ran some tests

History
03 Model Australia RX8 (04 in states) 4 PORT Automatic

113,000kms, 73,000miles

No engine rebuilds

Only premixed for past 3,000kms.

Now this was done without Decarbon, last Decarb was about 10 month ago! (oops)

Ok the compression ratio

Crank Speed 245
Front 117 119 114
Rear 108 117 111

I also have a boost gauge atm (no boost im a ricer)

At Idle (since auto i presumed in neutral) (WARM)

Vacuum is reading at 18 - 17.5

At Cruise its generally around 24 - 25

Now how does my engine look? since the high mileage i am abit worried about the health, so just grabbing the experts opinions on this!

In Terms of service History

I have been using for the past 50,000kms (when i bought the car) Penrite 5w-40 Semi-Synthetic

Workshop serviced every 10,000kms,
