new NHRA altered wing mount rule

[janjon]

I sense a new SFI spec on the way... or at least a proactive common practice, based on Tony's solution, it makes perfect sense to me. Sort of a chastity belt against struts trying to poke holes they shouldn't, deflected from the confines of the cage.  As for the racer with the struts chasing him, did they catch him? Sure hope not.

I'm going home from Florida this wed. 3/26. I have a new wing mount almost done. BUT I'm going to add tubing to each of the pair of struts to show what I'm suggesting as a viable solution. I will take pics and post so everyone can get a better understanding.

Steve sent me these photos of his new additions....I have forwarded them to Gibbs, Hullinger, Bowers, and Snead.

Here's how Dave Benjamin did his new AA/FA.  Sure looks the part, and no wing for the NHRA to mess with.

 If he had removed the rod ends, drilled two holes in the cross tube, slid it over and welded to the tube adapters anything sticking out would be shorter than the diameter of the roll cage tubing.

BK...that is true....The ends are tapered so it would take more "fitting". They are allowing 6" so this was a quick way that most of the altereds could get done to be safe. Keep the ideas coming!!!!!!

Dont laugh at the artwork...only so much you can accomplish with Paint.

Run the tubes straight up off the housing. Connect to the shoulder bar using the allocated amount of brackets and then bend the tubes back for a desired amount of rake.

This will allow the bodys to still flip up with minor cutting.

any updates on this?i'm in process of building a taller cage on my car to give me morehead room;;too tight.unsafe for me to drive..anyway now be good time to remount wing the way they want them for 2015..

You'll have to wait for the great and all knowing to walk down from the mountain top with the new rules.

Thru NHRA contact Bob Blackwell .The issue was handed over to him

so...does anyone know what we are doing with the wing on the roof of our cars

[Nightmare AA/FA]

Bruce is up to date on what's going on.  Maybe he will chime in.

Copy and pasted from the 2014 NHRA rule amendments:

Beginning January 1 2015,all open wheel/body cars where rear wings are permitted the wing may be
fully mounted to the roll cage or frame structure only via plates and/or
short brackets; maximum 6-inches center-to-center between the upper
(wing tab) and lower (roll cage tab) bolts. Tube type or extended wing
stands are prohibited when mounting wings to any components of the
driver’s compartment of any SFI specification roll cage.

I just went to NHRAracer.com and looked at the 2014 to 2015 rule changes as of 10/30/14 and I don't see any reference to the wing mount issue. Did they drop the rule? maybe next year?

Thats it---no changes, as was explained to me (this is a saftey committee ruleing and not the chassie committee) unless a SFI spec is written on the way the struts are mounted to the back of the car. That will not happen because even with a over-kill spec things can still happen and the racer will look for sombody to blame.

Its a grey area BUT---- If one were to make the struts a permanet welded fixture to the cage and not bolt on, one could argue that it is an extention of the roll cage and that constuction exceeds the MINIMUM specs for the cage itself since it is not removable. The thing that they are trying to get rid of is the bolt-on mounting method , because without a spec people are using too small of bolts-tabs(single shear)-heims and the tubing itself.

probably just going to leave the wing off I guess....get your cameras out
