All it did was show manifold vacuum in a red, yellow, or green section of the dial. Green being the most vacuum. We were a cave-dweller culture back then! Today's MPG indicators measure actual miles per hour and real-time fuel flow to calculate MPG. There is often some averaging to make it halfway sensible as well. This was part of the American Package of platform shoes, and emissions control that smelt of rotten eggs and had more vacuum tubes than the space shuttle has wires that made cars ping badly, then "run on" after turning off the key. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, June 13, 2008 7:02 AM To: [EMAIL PROTECTED]; [email protected] Subject: Re: MPG up 50% so far In a message dated 6/12/2008 10:38:38 P.M. Eastern Standard Time, [EMAIL PROTECTED] writes: I checked my mileage today and it is up 50% since I started the project (30.5 MPG vs 20.0 MPG). I'm pretty psyched about it because I have not really spent much time working on the car. It would seem that I could possibly get to 40 MPG now instead of the 35 that I had for a goal. So far the only mods I have done are removing the SC (intake is just a PVC coming 90 degrees out of the manifold with an FM purchased K&N filter), pumping the tires up to 50 PSI, and dropping the Master Fuel from 100 to 90 (RC 440s). Of course, I have changed my driving habits quite a bit. Impressive, but you can probably drop the fuel setting a bit more. FM's "standard" setting for turbo with 550s is 87. You have 440s and now no FI. Keep in high vacuum when cruising. If you need aditional encouragement, try adding vac gauge to go with or replace the boost gauge. I'm not entirely certain, but on cars equipped with "MPG computers", I think those computers are registering vac numbers (and probably fuel flow info) on an MPG scale. I use the one in my Subaru (big 2005 Legacy) when driving that car, and by staying in high vac I average about 27-28 MPG, where I used to get 23 -24 when not paying attention. Watch out for tire wear, especially in the center tread. ________________________________ Vote for your city's best dining and nightlife.
