RULES and CLASSIFICATION FORMS REVISED AND INCORPORATED

 

We have released the latest version of the 2006 NASA TT Rules (v. 3.9.6, April 17, 2006) and an updated version of the TT Car Classification Form to match them. They has been substituted for the prior versions, and use the same download links http://www.nasaproracing.com/rules/Time-Trial-Rules.pdf and http://www.nasaproracing.com/rules/Time-Trial-Classification-form.pdf. The primary reason for the new release was to incorporate all rules revisions and addendums as well as Provisional car classifications and approved engine swaps that have occurred since the original release of the rules. This will make it much easier for both competitors and officials to have a single document to refer to. Hopefully, there will not be a need for any further addendums, rules revisions, or base class changes in 2006 (although we will undoubtedly continue to have new Provisional Car Classifications and Approved Engine Swaps as the season progresses and NASA TT continues to grow). All changes to the rules have been written in red to make it easy to distinguish any changes from the prior version. There have been a few additional changes to clean up some minor issues that you should be aware of:

 

1) The rules emphasize that TT will only be run in "advanced level, open-passing sessions".

2) The following has been added to the wording of the +12 points for shocks/dampers modification to clear up the intent of the rule once more. "Also, any shocks/coil-overs with a retail price of greater than $750 each."

3) "Shims" has been added as a method of obtaining camber that costs +2.

4) Since off-the-shelf retail camber plates have slots that often allow for a slight amount of caster adjustment, some wording has been added to make them legal as long as caster remains within factory specs.

5) Retail camber plates that have a pillow-ball joint will not also incur a +3 assessment for metallic/mixed bushings.

6) There is added language to encourage drivers to obtain and use as much NASA CCR compliant safety equipment as possible.

 

Reminder: There were new rules put into place earlier this year regarding the classing of cars that were built originally with naturally aspirated motors, that subsequently have switched to forced induction. All of those cars, as well as all cars with engine swaps need to be individually classed by the National TT Director, and most will require chasis dynamometer testing to help in classing them. TT Rules Sections 6.3.2 and 6.3.3 have been added to the new TT Car Classification Form download as a reminder of those rules for aftermarket forced induction and ported rotary engine vehicles. Also, all competitors that are running under dyno hp restrictions are encouraged to leave a cushion when tuning the car, as the car needs to be compliant on each of the three major types of Dyno's available.
