Chute weight.
« on: January 11, 2019, 07:32:19 PM »
Hey.
Has anyone got a 4 line chute and pack off their car at the minute they could drop on their wife's bathroom scales please. Just looking what I don't need to save a bit of weight. So far it's - wheelie bars, battery, sundry wiring, a couple of cables, lead on the nose and get the hole saw out into the gas pedal and sundry brackets. I reckon there's a hundred pounds there with the chute. I hit 200 on the scales last week so I know I can knock 20 off that.  I've just gone to a 12" rear disc so don't reckon I need the chute and hoping I can balance the launch with better use of a little weight on the nose. 120 pounds has to be worth something.
Cheers

How fast are you planning on going? 150mph+ chute is required

If it ever starts to bounce you will wish you had the chute. Ask me how I know.

Might look  into smaller chute. I know from large to smaller chute can be 3 to 4 lbs saved. A lot of place to cut wieght and would go most before removing chute IMO. Fast is great and be able to come back to next round ain't bad either.

I watched a guy with an old Vega funny car go into the woods somewhere around 100mph several years ago. He had pulled his chute off and left it laying in the trailer. Then proceeded to bust a brake line with rear brakes only. The car was totally destroyed, if he had a chute on there at least it would have been a lot slower when he ran out of shutdown area.

The total weight of the 4 line chute, chute pack and pop chute on my car is just under 5 lbs.

 5 lbs with careful shopping can cost around 500 bucks to shave off and only .005 in 1/4. Risk to reward ratio ,sounds like bad investment IMO.

I only go to eighth mile tracks and have just upgraded my brakes. The car is currently in bits it's started to pick up a few extra bits and pieces (as they do) so I'm just asking myself what I can get rid of. A parachute I never use - see ya. Couple of surplus cables and wire - bye bye. I had some starting and stalling issues while sorting my one off injection so fitted a battery - ugly up front so I hid it out back among my wheelie bars. Added weight to the front axle to counter the battery position. Starting stalling issues sorted so time to go back to a plug in battery and get rid of 60 lbs of unsightly fat - you getting the picture? Anything I don't need is going in the bin. Anything I hit with the hole saw I'm hitting, and thing I've made from steel that I can replicate in aluminum like my shifter. will be happening. I'll weigh everything up when I'm done just to see.
Cheers

Why not do a back-to-back test, removing and adding the weight of the chute, and report the difference in e.t. to us? I'd be interested to know.
I kept the chute on my altered when we went totally to eighth mile Super Pro racing at the tracks I run for the Kool factor it gives it.

There are more track variables out there that will alter ET's then would a pound or so in a chute pack. Drop the weight and work on RT's  those 2 things cost nothing and have the most impact

Reaction times are extremely important, but how can they help your ETs?

 ET is not that important if you get to the finish line first
