NASA Prototype Rules Change Requests – Summary

 

Approved for 2018

 

1. Mandate bump stops front and rear ~$75

Approved, reliability. Front bump stops are now allowed to help keep nose/splitter from bottoming. To eliminate the need to test for different tracks and conditions, the spec stops will be mandated on all cars.

 

6. Allow side window vents ~ $250

Approved, driver comfort. Allows better venting and ability for “point-bys”.

 

7. Increase minimum weight

Approved, parity – Changed to 1775lbs. Reduces the number of competitors who are unable to meet the minimum weight.

 

8. Allow air intake scoop ~$500

Approved. Will improve top speed performance.

 

13. Allow modification of canopy to make removal easier

Approved, serviceability. NASA tech bulletin to be created for details.

 

14. Allow any manufacturer for master cylinder (maintain same size) ~ $250

Approved, reliability. Any brand with similar list price (<$150ea) is permitted.

 

15. Open fuel pump to any manufacturer ~ $150 to $250

Approved, reliability Permit Bosch 044, AEM 50-1005 or Holly 12-935.

 

17. Fix front spring rate at 600lbs

Approved, cost containment. Following the intended path of decreasing complexity of suspension setup and testing.

 

18. Fix rear spring rates at 2 choices (1400/1600)

Approved, cost containment. Following the intended path of decreasing complexity of suspension setup and testing.

 

19. Allow wheel speed sensors on all corners ~ $75 per corner

Approved, driver development. Allow for driver development and aid in setting bias bar.

 

20. Specify (or leave open) where extra splitter support cables may attach.

Approved, reliability. NASA tech bulletin to be created for clarification.

 

21. Allow addition of Elan oil cooler kit. ~ $600

Approved, reliability. Help with cooling during high temperature and/or high elevation events. Elan to create tech bulletin.

 

 

Not Approved for 2018

 

2. Allow any size master cylinder ~ $250

We need data showing changing master size would help bring the balance bar ratio more neutral.

 

3. Allow 1800lbs rear springs ~ $150

Class focus is to limit # of choices, no proven data showing need for stiffer springs than 1600

 

4. Allow any rear suspension pickup points - no material costs

Class focus is to limit amount of adjustments to caster/camber/toe/rake.

 

5. Replace water temp sensor with head temp sensor ~ $1500

No significant need provided with request. Rule will be rewritten to allow coolant pressure sensor or extra temp sensor to be hooked to AiM.

 

9. Allow front high downforce splitter ~ $7500

Not within cost containment intention of class

 

10. Allow front splitter ramps ~$1000

Not within cost containment intention of class

 

11. Allow rear diffuser (see #9)

I need ideas to add 50 lbs of ballast. The two lugs on the frame just in front of the seat tub does not have much room to add a lot of weights.

I have used the bosses for the heel stop in front of pedals also. The weight made a great heel stop also. Dave put lead shot mounted under his seat also.

Yep. I took lead shot and poured it into the two cavities under the seat. Then adhesive and rivets to secure flat aluminum sheet over the top.

 

The two bosses in front of the seat are good up to 65lbs per Elan.

Now I have an excuse to eat well; to make spec weight.
