[TOOSTUBBORN2FAIL]

Decided to test this out today.

7.5 miles of freeway, at 55 mph each way, 4 1 way trips averaged together for each test.

First test was alternator connected, no accesories on.

4 runs averaged out to 42.7 MPG, measured with scanguage. Run differences were less then 1% error margin.

Second test was with alternator connected, lights and fogs on, ac on (my belt is removed, so this is the added load from thee compressor clutch, engine fans being on, and hvac fan).

4 runs averaged out to 40.6 MPG, measured again with scanguage. Run differences were about 1% margin of error.

Last test was with the alternator belt removed.

4 runs averaged out to 43.6 MPG. Same measuring standards as above.

So i was pretty dissapointed in the results, about 2% better then with the alternator with no accesories, and 7% better vs having accesories running.

Couple things that might factor into my lousy results.

At 55 mph, in 5th gear, i have way more then enough power. Stock hp and tq ratings at the crank are 150 hp and 133 ft-lbs. Additionally im at 2500 rpm at 55 mph. And the engines a 2.0L.

Maybe with the other tranny and tires (1900RPM at 55mph, and lower RR) id have some better results, as well as if the car was a SOHC instead of DOHC (sohc has 1 mm smaller valves, as well as a milder cam and a tiny bit more compression)
