Manifold Vacuum Experiment
I want to come back to this and report on Vixen. We drove her to Milledgeville today to a small cruise in and to grab breakfast biscuits. Then, went to Harbor Freight to get a hand siphon and finally WalMart for cat food. All in all about 60-65 mile round trip. I can tell a bigger difference than I first thought. Much like Gladys, Vixen feels stronger with just the throttle "cracked" going down the road. It just took a little more distance for me to recognize it. She didn't miss a beat. Also, without a doubt, she's using less fuel and running cooler as well. I'd say this experiment was a double success.
