LSR Classes Team Elves are running

Running at
Bonneville

What classes & how fast:

There are 4 levels of preparation: Production, Modified, Altered, and Streamliner. Then there's classes for different displacements (ours is 1000cc), gasoline or fuel, pushrod or OHC, and boosted or normally aspirated. Furthermore, Modified and Altered have a "partial streamlined" classification. Almost all possible combinations of these things are available as a separate class.

Official results are posted for Speedweek and these are the classes we currently hold:

Class Speed Current record holder

APS-PG 161.052 MPH Team Elves

MPS-PG 161.207 MPH Team Elves

MPS-PF (fuel) 180.823 MPH Team Elves

APS-PF (fuel) 158.245 MPH Team Elves

APS-PG: 1000 cc/ Altered Partially Streamlined Pushrod Gas class

MPS-PG: 1000cc / Modified frame Partially Streamlined Pushrod Gas class

MPS-PF (fuel): 1000cc / Modified frame Partially Streamlined Pushrod Fuel class

APS-PF (fuel): 1000 cc/ Altered Partially Streamlined Pushrod Fuel class

ERC is the official gasoline supplier. To run in a gas class, you must use their gasoline, which is available on-site. If you run any other gasoline, and/or nitrous or nitromethane, you're in automatically in a fuel class.

The rules for M and A are pretty wide open. Most of the rules deal with safety requirements (chain guards, kill switches, etc). There are some streamlining restrictions, for example, the rear rim must be visible for 180 degrees behing a vertical line through the rear axle, the fairing nose can't protrude farther forward than the front axle, and the front fender can't cover more than the top half of the wheel. There are no engine restrictions other than only one is allowed in M, any number is okay in "A". "A" allows wheelbases over 72", M does not. To configure the bike for "A", we'll take advantage of a tiny rule difference that requires "M" class footpegs to be at least 6" in front of the rear axle. This is how the Goose team did it.

How is it done and measured:

There's a "short" course and a "long" course. The short course consists of 2 miles of approach, followed by speed measurement over the first quarter mile of the 3rd mile and another speed measurement over the entire 3rd mile. Records are based on the entire 3rd mile. Any vehicle can run the short course, and only vehicles which exceed 175 within the first quarter of the third mile can use the long course.

If you exceed the existing class record by .001mph or more, you've "qualified", which means you get to try it again. But first you have to go to impound, and you need to be there within 1 hour of the qualifying run. You then have 4 hours to perform maintenance. At some point, they let you make the second run. After your second run, they average the two runs and the result is your speed. If you broke a record, you go to tech inspection, where they try to find out if you cheated.
