then its you and me AZSaleen04!!! Haha!

On a serious note. I am trying to find basic rules for the track and the website points to the NHRA website, which is a bit overwhelming. I am mostly wondering about helmet, driveshaft loop, rubber oil/fuel lines in engine bay, coolant overflow size, battery hold downs, tread depth requirement.......$hit like that.

anyone got any links to general car requirements? Thanks.

Some general rules:

-All cars must have a catch can for radiator overflow of at least 1 pint. These must be securely fastened (bolted or clamped). Factory overflow in most late-models is fine.

-Neutral safety switch (again, if using a factory shifter, this should be already installed. Aftermarket shifters will require wiring this in).

-If battery is in the back/trunk (regardless of ET), a secured tray and cutoff switch is required. The cutoff switch must shut down everything electrical when off; see here for pictures and a wiring diagram: http://www.ls1tech.com/forums/drag-r...ct-switch.html

-If using Nitrous oxide, the bottle must be securely mounted (no plastic brackets), bottle must be stamped with 1800-lb DOT rating and identified as nitrous oxide. If bottle is located in driver's compartment, it must be equipped with a relief valve and vented outside the compartment. Commercially available thermostatically controlled bottle-type warmers are permitted, all other heating of bottles prohibited (i.e. blow torches).

-Any vehicle using a spool center section requires aftermarket axles with positive retention (c-clip eliminators).

-NHRA national and divisional races require clear glass around the vehicle, subject to check. Local races vary, check with your division or track.

-Tires/Wheels/Studs and lugs/spacers:

Tires may be checked for condition, pressure, defects, etc. by a tech inspector before allowing runs. All street tires must have a minimum of 1/16 inch tread depth. Temporary spares, space saver spares or trailer tires prohibited.

Thread engagement on the lug must be equivalent to or greater than the diameter of the stud or bolt. Length of the stud/bolt doesn't determine permissability (example: a 7/16 inch stud must be thoroughly engaged through the threads in the hex portion of the lug a minimum of 7/16 inch.

Spacers are allowed and can be either hub centric or lug centric. Spacer can not reduce the minimum permitted thread engagement below the standards listed above. No stacking of wheel spacers allowed.


13.99 1/4-mile (8.59 1/8-mile) or quicker:

-A driveshaft safety loop is required when you run slicks (not drag radials or street tires). With street tires or drag radials, no loop is required until 11.49 1/4-mile (7.35 1/8-mile) and faster.

-A helmet (closed face or open) is required with a minimum Snell K98 or M2000/SA2000 rating. Helmets last 12 years from their rating date (example a Snell 2005 would be good until 2017). Shield is not required.

11.99 1/4-mile ( 1/8-mile) or quicker:

-Metal screw-in valve stems required on tubeless tires on all wheels.

11.49 1/4-mile (7.35 1/8-mile) or quicker:

-A 5-point minimum roll bar on a fixed roof car (t-tops okay as well if in place while racing) from 11.49 to 11.00 (7.00 1/8-mile). If the hardtop / t-top car has un-altered floors, firewall and frame rails (wheel tubs are okay), then the 5-point roll bar is good til 10.00 1/4 mile (6.40 1/8-mile). Convertibles require the 5-point bar from 13.49 (8.25 1/8-mile to 11.00 (7.00 1/8-mile).
The rollbar must be constructed of a minimum o.d. mild steel or chrome moly tubing (moly can be a smaller o.d and is lighter but more expensive), see diagram below for specs.
The roll bar can be bolted or welded to the floor, see diagram below for specs.
Roll bar must be padded anywhere the driver's helmet may contact it while in the driving position, see diagram below for specs.
The 5-points are:
Main hoop; 2 "down bars" (bars that go from the main hoop rearward to the trunk floor/hatch area. These can be straight or bent like a "package tray" style, search for photos); Welded crossbar for belts (can't be removable), see rulebook for exact location. Driver side door bar (can be a swing-out. Many put a passenger's side bar in as well (6-point) because it strengthens the car on both sides, but if you have subframe connectors the difference may be minimal).

-Protective Clothing (SFI jacket with a 3.2A/1 rating, no expiration date)

-5 point harness (up to date, they must be replaced or re-certified every 2 years; You can re-cert by shipping the belts to the manufacturer, or buy new ones. I usually buy new ones and sell the old ones on EBay (street racers and dune buggies buy 'em).

-SFI-approved flywheel and/or clutch (no expiration date)

-Screw-in valve stems

-No tint allowed on window except factory

Let's do it.....

I am wondering how do I know if my helmet is ok to run with.

I have a HJC and in the back it states SnellM95 DOT.

Is that ok?

I am not 100% sure but the M95 would have been good until 2007, if the ratings are good for 12 years. I too have to round up a helmet.....

I have a crack in the front windshield that runs from the bottom straight up to the top, will they let me run with that?

[AZSaleen04]

I just went and bought a new helmet it wasn't bad $150.00

I was talking to Tony earlier and he said they are strict on the helmet and will look at the inside. I ner knew a helmet had an expiration date.

just a reminder if you have street tires or no skinnies up front go around the waterbox, if you have a tire that needs the waterbox back into it

Ruckus46gt was does a 5 point cage look like?

[IMSHAKN]

Yes, that will pretty much get you through tech
