Title: Chute Deployment for First Timer
Post by: dusterdave173 on October 28, 2014, 03:25:07 PM
OK
I am a rookie FED pilot--though have drag raced for over 25 years.
I have 6 laps on my new FED
I have a match race this Sat--going to be lots of fun so I was thinking about opening my Chute even though we are only running the 1/8th so folks will get the best show possible.
Thing is...I have never opened a chute on anything before
I have packed it several times--my controls are adjusted and work good
How do I do it--what do I expect--what to watch out for--when to let her rip?????
I expect calm weather No wind if weather report is good

Do I stay in it and pull it right at the stripe or???
A little advice from the pros please

Thanks!!!!!!

You can drive into it or pull it as you step off the gas. As you are only running 1/8th mile it won't open hard but make sure your shoulder belts are tight anyway (they should be that way all of the time). The first time I pulled the chutes while I was making the runs for my NT/F ticket I was going around 190 mph and with a pair of 12 foot chutes that will get your attention right now!
Make sure that you have enough speed to make it to the turnout and once you are clear of the track pull up as soon as possible so that you don't drag the pilot chute too much-they take more of a beating than anything else.

Pull at the line,no big deal. The first time I pulled my chute on an Altered running mid 8's. Got out of shape ,ready to turn over,pulled the chute and straighten the car out. It saved me that day, but no big deal.

This not offered as advice from a pro by any means, just my little experience. Mine goes through the lights at about 125, and if I pull the handle right at the line there's what seem like a goodly part of a second before feeling it slow the car down; so you could let it out a bit before the finish line. At that speed it is not an eye-opening experience. Barely a car-straightening tool either.

It also depends on the size of the chute, and how the chute is set-up. The bigger the chute the bigger the hit or the more MPH the bigger chute is needed. That's why NHRA has a rule any car that runs, or can go over 200 mph must have two chutes. 
The set-up deal is the closer to the car where the chute lines come together, the softer the hit or the slower the speed you are going. The closer to the chute where lines are attached the bigger the hit or needed with higher MPH or the heavier race car. Because the chute is catching more air.
Ya, you are right, EVERYTHING has to be tuned to work together.
Remember you need to wash the chute once in a while or more often if you are dragging thru the dirt more often. And carry a spare pop chute, they wear-out from dragging on the track/ ground.
Have Fun !

looks like you already have the good advice.   but have to share this a friend of mine runs a 70 Gremlin.  With the iron 401(all motor) it was running 8.30s in the quarter, now with some upgrades and juice he is putting down 7.0s I asked where he feels the power/speed.  Fully expecting the 60ft or top end. He says when the chutes hit.  I thought that was pretty interesting that a speed freak would say the decel.

Steve  you brought up a really good point ! One of the most dangerous places to be at the drag strip is the turn off area ! I have seen more mishaps there than on the drag strip . The driver of the car has no idea if his chute is still blossomed . You and your crew have to be on there toes whenever a car comes around that turn .i have seen cars ,crew members ,pit bikes and track workers get caught in parachutes !Wayne Hoffman told me that that his dad one time picked up an NHRA guy on a scooter with his funny car!

Hi guys.
I am allways learnig something new when I open this forum!  i am building my first fed (slowly) and was thinkin about how you guys choose your chute?  Is a 12foot chute for a big dragster or a small one??
Thanks
Palli P

Palli P, that makes 2 of us enjoying learning from this forum.  I think our race rules require one chute over 150mph and two chutes over 200mph (like Jon said above).  If you have a good drag racing 12 foot chute available in your locale, I’d probably install it.  Just a thought (your new fed build) even more important than having a parachute is assuring it’s mounted proper to chassis : )  Alan

I hear that Stroud style chutes open softer and are easy to repack--I have a new Simpson because I bought it for a sweet deal--it has lots of lines and I can see how the other styles may be a little easier to live with.
I rather doubt I will need a chute to stop--If my car goes faster than 8.50 it will be a miracle--I am thinking with a 5.60 1/8th I will just break into the 8's maybe.
But..I feel like folks that come to see a FED run deserve to see the Chute--I posted this on our club website and added that I thought since we Were the Show that we all should pop the chutes each run
Boy..that went over not so well--I got comments like use for me and car safety only etc
I was not expecting that
I just want to be comfortable with every aspect of my car and did not want to toss chute first time and wind up in the weeds because I did not know some fact like not with a crosswind or some such--you get the idea
Glad this post is helping more than just me

Thanks for all the info gang!

I just did lic passes in march and ran 7.92 @ 171 on second hit and pulled chute just before stripe and drove into it. had to look to see if chute was out after pass. single chute. was not what I expected at all. just was expecting much more I guess or was just too pumped up either way it was very cool.

hemidakota,
                   my first time took a while. When I drove in the late 60's/ early 70's it was a restricted category six cylinder car and there was no need for a chute as it only run a bit over 120 mph. When I finally got back into a car nearly 40 years later it was a nostalgia top fuel dragster and the first time that I went fast enough to feel that I needed the chute was on the full pull run for my license. 186 mph and two 12' chutes put my head in the dash (not literally but it sure felt that way).

I made a habit of pushing the chute lever forward at the MPH cone (66 before the stripe).  Just something easy for this dumb dumb to remember.  I bought my car with two chutes on it, and i pull both each time (one lever, two wires).  Why? because it makes bitchen pictures. 

I can stop fine with no chute, with one chute, and with two chutes i JUST make the first turnout @ Famoso.  :)

1880# car, 178mph, 7.60 index car

BTW, mine are Stroud 420-6 chutes (the 6 is the color, the 420 is the size).

Driving into the chute... can't really see what the difference would be between releasing it with the gas still on, and (very) shortly after letting off. 'Twould seem the drag would be related to the speed, and not to whether power still is being applied, being that acceleration, ACROSS the finish line is essentially zero? From the sensory standpoint as mentioned by the earlier poster that his friend gauges speed by parachute impact, I can think that timing the hit of the chute to coincide with stepping off the pedal would maximize that sensation but not be considered a "technique".
 I also agree that popping the chute for any spectator appeal is a good thing; I run my car at a track I could get it stopped reliably, (probably) but if anything unforeseen went wrong it would be too late by then. I got it bouncing on the brakes once, and found that banging the helmet against the cage is painful! I will bear the burden of packing it every time. Let the turnoff bystander beware.

Hello Duster, we were one of only two Nhra A/F cars that I know of who actively licenced people in there car one of the things we teach is to drive with one hand and get your chute hand behind the lever to grab on the wat to the brake lever if something freaky happens to help get the car back under control I know from the experience driving a friends cars even just off the starting line when an axle broke and it kept me off the wall. What you are looking for is to be in the habit of pulling the chutes so as to hit as you cross the finish line to have the laundry out as soon as possible mainly for the short shutdown tracks. It is VERY IMPORTANT that when you get get off the throttle that you get on the brakes and DO NOT let off even when you feel the chutes hit as it wouldn't be the first time a chute hit and imediately ripped enough shroud lines to collapse. Only when you are sure you feel the car really slowing down with the chutes do you want to ease up on the brake to make it to the turn off. Letting off the brakes without the chute blossomed and tugging on the car will send the car bouncing badly from the stored energy in the tire from braking and loading the tire in the wrong direction I have photo proof of this as well.[lol]  You didn't say if you're running 1/8 mile on a 1/4 mile or 1/8 mile track but if you're on a 1/4 mile track and running 1/8 mile you can get away with just pulling at the 1/8th and hope it will coast to the 1/4 mile shut down but you would be much better off to be in just on habit or routine every time you drive as it becomes instinctive and autonomous to reactions. I hope this helps you and good luck.

I'm sure a lot of you guys may know this but for those who don't some chute manufacturers actually make two lengths of pilot chutes and some others are longer than others the longest one you can use will be the best to help deployment.
