Drag Strip Safety Rules

Im getting ready to run my car in the 1/4 mile and was wondering if there is somewhere online that shows what needs to be done to a car to be "Legal" for racing at the track. All I want to do is run time trials, but want to pass inspection. I want to check for running up to 9's. A few people told me that the track where I live is getting strick.

Different tracks have different rules.............but to go down in the nines at a 1/4 mile track..........will require some serious safety items........roll bar, drive shaft loop and most likely non stock axle shafts.... at least.

Yep, go ask at your track, or become an NHRA member & get a rule book, that way youll be covered at ALL tracks. Theres a couple 1/8 mile tracks not terribly far from me that dont have any safety requirements, but they are both unsanctioned...so kinda depends.

the nhra book will get you there, but i've never been to a track that if you ran faster than a 12 and didn't have a cage, you'd be invited back. keep in mind, i don't get out much....
dipping into the 9's is a whole nother ballgame$$$... sfi certs required then.

After the first 9 second pass, they will IMMEDIATELY stop you and tell you your gonna get thrown out if you do it again without a NHRA license. 9's in a street car are pretty difficult. So don't panic. There's more to getting a 9 other than horsepower (450+) Traction issues are ranked right up there.

Your best bet is to take a ride to the track and ask the tech guy what you will need. I'm sure you will need a Snell 2000 rated helmet as well.

Have fun, and don't try to make your first pass a 9. Make a few passes to be sure the car launches straight.

You will need an NHRA certified cage for sactioned tracks or events. Cage has to be built by the book. You will also need SFI balancer and flywheel along with trans blanket and scatter shield. You will need a drive shaft loop on the front of the drive shaft. You will need axle retainers other than c clips. You will also need a saftey electrical disconnect on the rear of the car. Also need SFI seatbelts. There are a bunch of little things I am forgetting. I cant remember the site and cant find it, but google should find you a camaro site with an old rule book that will get you close.

Geezzz, Well Im way off. I have the driveshaft loop and fire suit from running in the 10's before.

Thursday nights and saturday are what they call time trails. They do not have any racing. How close are they going to inspect my vehical?

My balancer and flywheel are not SFI. How will they know if my flywheel/balancer is SFI certified? I mean I'm not running in any type of class for racing. Will they let me slide on some things? I just want to do time trails to have fun, nothing else.

If you need a custom roll bar, how can I make it certified by NHRA, why can I not just weld one together, and make it look good enough to pass inspection.

NHRA certified tech

Any tech person on the track should know the rule book inside out.

Cage and chasis certification has to be done every 3 years. Belts, helmet, suit, balancer, flex plate all have dated tags. If they are removed. You fail.

Roll cage is very explicit. 1 3/4 chrome moly tube. Must be tig welded. Main hoop cannot have kinks in the bends. Rear down angle 30 degrees, no further than 6 inches from top of bar. Front down angles must pass between elbow and shoulder. Seat no further than 4 inches from shoulder bar. Shoulder cross bar no lower than 4 inches below shoulder. All points must be welded to the frame except in monocoque bodies. Where you must have 4 x 4 inch sandwich plates. Plates must be held in place by 4 3/8 inch bolts. The inner angles must attach directly to the frame extenders. Top hoop must be 4 inches above drivers helmet.

Lap belts must be on 45 deg angle from drivers body. All five points must be attached to frame or have re-enforcing plates under the body.

List goes on. I suggest you get NHRA rule book.

Your first 9 sec pass without NHRA drivers license will result in warning against another 9 sec pass.

General rules are posted here

The Rules

The Rule:
Find out what sanctioning body your local strip operates under, or if its an outlaw track, contact them, and get copies of their rules, or in the case of many outlaw tracks, find out what sanctioning bodies rules they do use, as well as any changes, additions, or abrogation to those rules they have.
Even sanctioned tracks may have used option clauses to alter or add rules of their own.

Just one quick question for you.

Why would you want to shirk the safety rules? When something goes down bad, you'll wish you had that safety item. I mean, you only need a helmet IF you crash, right? Ever been in a bad crash?

So tell us, what did you have that ran in the 10's? We like seeing pics!

racing

Am I to understand you have never raced before and plan on making a 9 second pass on your maiden voyage?

I'll send flowers.
