Chute lever relocation
rooman:
Most "big show" cars have the chutes on the right just ahead of the front hoop of the cage so that you can do as Bruce suggests--back of your hand against the hoop, slide it down and push forward on the chute levers and then tug on the brake lever. Fuel shut off is generally on the left and most funny cars have the fire bottle lever on the brake handle.
In my cars with auto transmissions (and foot brakes) I generally mount the shifter on the right and the chute lever on the left.
This is Brendan Murry's NT/F car that I built a few years back. As you can see, when the chute levers are pushed forward your hand is right in line with the brake lever. As with a funny car the fire bottle lever is on the brake.

Great picture totally understand, now I am looking at this is it best to have a separate lever both chutes? I currently have both chutes deployed from a single lever my thought on this is if one does not deploy once I determine it I will have traveled so much distance that the by the time the second chute is deployed it may be to late??
Any insight on this

"Big Show" cars also have a lot more room and the driver sits different. Sit in the car all suited up(thats makes a big difference also)helmet included to find you best option. With some cars the suited driver cant bring his hand back far enough to get behind the levers to push forward if on the right, and bending them in gets the driver tangled up while climbing in. Bottom line is that you can not fit the controls of the car unless you are suited up and belted in the car to find out what works best "EVERY TIME"

I guess that it depends on how fast your car goes and how long your track is. Running at Bowling Green for example it is a good idea to use both chutes in a nostalgia top fuel car but with a 7.0 car at around 200 mph two chutes will generally have you stopping on the track as the first turnout is a little too close to the finish line and there is only one other. Bakersfield has three turnout options that are spaced so that you have more leeway. Last September I ran 182 mph in Mark Vaught's car at Indianapolis Raceway Park and only pulled one chute. I probably should have used both as I was going a little too fast for the early turnout but not fast enough to make the second and the top end crew had to come out and get me. By the same token, I ran 186mph in Dan Horan's NT/F at IRP and stopped without the chutes. In that case I hit the chute and already had my hand on the brake when I realized that it was not opening so I had plenty of room to get it slowed down on the brakes. In that case it was a judgement call--do I let go of the brake and try the chute again (using up some shut down length in the process) or do I rely on the anchors?
