Engine is running sooooo sweet!


I did post this over in my AC thread, but no feedback so let me try here...

I had recharged the system with fresh R12 over a year ago, and the AC was working great, but I noticed the sight glass on the old dryer was leaking.
It was still blowing pretty cold, and the static pressure I had was about 65psi.

When I did the Dryer replacement, I used my AC unit to evac then recharge the system.
It took out about 14oz total from the car.
When I tried to recharge the unit would only put back 16oz.
The hood badge says 1kg or 2.2lb.

Despite only putting less than half of that in, the static pressure is about 110psi today...

The AC works great, in fact I just did a vent test and with the ambient in my garage reading 75degF I am getting 30degF at the vents at 2000rpm.

Anyone care to comment???
