Mid- Engine Modified Sports

The safety techs are trained to go to either end end the vehicle  to find the shut off so it's your preference. Push or pull is also your preference.
I like pull off in rear of car as it keeps things tighter to the body in the RUN mode and the rear of the car is all dirty air anyway so no measurable drag penalty.

I hadn't thought of the aerodynamic advantage of putting the switch on the rear-- thanks!

Neal:

I put my cut-off on the rear with PUSH for OFF. Seems pushing something to the off position is a more natural reaction than pulling. Remember the safety folks will be moving quickly with their adrenalin pumping. I have a florescent arrow on top of the rear spoiler point to the cut off and one on the underside pointing toward the switch in case the vehicle lands on its lid. Lastly, I had a spare Morse throttle cable that was just long enough to reach from the trans tunnel behind my shifter to the trunk. I made a master cut of lever in my car to cut the power from inside the car. All power inside the car is low amp power to switches. The higher power accessories are run from relay's outside the driver's compartment. Now the secondary benefit I have found to the cable system is every time I sit in the car and forget to turn on my master switch I can reach over and push the lever to the on position.

My 2 cents.

I forgot to add the second photo of the side view of the cut-off switch handle in orange. The other handle is the parachute release.

That looks like a nice setup-- thanks.

We prefer pulling things when in the panic mode.  The fire bottles, the fuel shut-off, the parachute, the main switch.  We think it's easier to grab and pull as best you can.  We also believe the main switch in the back is the way to go with front-engined cars -- in case there's a conflagration going in front.

Stan;

The case of an engine fire makes putting the switch up front in my car more attractive-- thanks for that info!

Today I drilled the rivet holes for one of my 10lb fire bottle mounting brackets. Two 7075-T6 aluminum strips will be riveted to the bottom panel and these hold down two t-bolt clamps that retain the cylinder. The rivets are 1/8" A286 CherryLock so the bottle is very well secured. Clecos hold it in place temporarily.

You Might what to look at the new rule on fire bottle clamps. I took my t-bolt straps out and installed billet holders.
   Figured they would call the t-bolt clamps hose clamps.

Richard might be right, but if they kick titanium straps, I'd get a second opinion.

I just used 4" muffler clamps with rubber tubing, but they're clearly not as beautiful as these.

Roy Creel would be your contact - page 182 of the 2014 rule book.

What new rule on fire bottle clamps?

[RichFox]

Some years ago they went way from hose clamps with all the screw slots in them. So a lot of people went to the T bolt muffler clamps. As far as I know that is still OK.

[manta22]

These T-bolt clamps aren't built for mufflers; they are industrial clamps-- heavy duty 1" wide stainless. Thanks for the concern. I think Rich is right-- that rule is to prevent the screw-type clamps like he described.

I found a local plating shop that will do small odd lots. There are a number of small items that I'd like to get zinc plated instead of painted. I'll take them to him in a few days.

Neil - you've got to stop upping the game - you're making us all look really bad . . . 

[tauruck]

That's a neat solution Neil.

You've just given me an idea.
