Fresh Boarder Posts: 75 Re:Verdict is in - 33-tooth Pulley MPG 2 Months, 2 Weeks ago   Hey Earl how about a write up for a Tech Article on your change. Did you have to change belts etc maybe some picture. I looked through the tech articles and this appears not to have been covered before, maybe you documented it in an earlier post. Sure would be helpful to know of the do's and don'ts from first hand experience. Thanks Chris   Logged     Last Edit: 2008/09/05 11:54 By 2sheds.     The administrator has disabled public write access. #116466 SobaCracka (User) It's best to eat crow while fresh.

The belt and everything else stayed the same. Although, I did yank the belt rollers out next to the pulley because the belt touched them a lot more, and I couldn't stand the roller racket.   Logged     Earl in Catonsville, MD   The administrator has disabled public write access. #116688 onefastbob (User) WARNING!...I can be Annoying!

Pre-33-tooth pulley, I could expect about 41.8 MPG with day-to-day riding, speeds under 75 mph and usually under 65. On my long hauls to GA at intestate speeds 72-82 mph, I got around 34 mpg. Figured out what I got on my 2,000-mile trip through New England with the 33-tooth pulley, using 12 fill ups for the calculation: Overall average was 43.248 mpg or almost 1-1/2 mpg higher than my everyday average, but that included a few hundred interstate miles doing 70-82 mph. My low was 39.135 mpg on my last fill up (almost all interstate), which is roughly 5 mpg higher than the 32-tooth days...and my best was 45.261 mpg on a mostly two-lane day (35 to 60 mph), or about 3.5 mpg better than the previous average. Thanks, Derek, for the pulley. Conclusion, the 33-tooth did improve my gas mileage with virtually no loss to performance for my tame riding style. In fact, I like the way it feels a lot more. 50-60 mph in 4th gear is just cruising now, and I don't really need 5th gear until I hit about 75 on accel.Did you figure the MPG corrected for the 3% error that the different pulley causes? Changing the pulley changes the odometer roughly 3% per tooth (1/33=.03030). Something to think about.   Logged     Last Edit: 2008/09/05 18:22 By onefastbob.   My Image is NO longer illegal!   The administrator has disabled public write access. #116693 smhowse (User) NOPE, it's a Roadstar! Platinum Boarder Posts: 1417 Re:Verdict is in - 33-tooth Pulley MPG 2 Months, 2 Weeks ago   onefastbob... Soba, Glad you like the 33t change.I for one LOVE my 31t but, I love to get from one stop sign to the next as fast as possible Really for me I like the fact I don't have to shift as much in the canyons where I enjoy riding. It sounds like you enjoy the wide open road so the 33t works for you Thanks for the update!

Otherwise I'd be looking for a 33 as well. This is great stuff.   Logged     FREE SPIRIT 2007 Silverado   The administrator has disabled public write access. #116892 Goodygood (User) Junior Boarder Posts: 168 Re:Verdict is in - 33-tooth Pulley MPG 2 Months, 2 Weeks ago   Hey Soba did you have to remove the rollers?? Put out a post on the * project and got several said they had to remove the roller due to contact and an annoying noise it made.   Logged     The administrator has disabled public write access. #117062 SobaCracka (User) It's best to eat crow while fresh.
