Lot of talk lately about NHRA going 11.40 w/ a Belted Radial type tire (Nittos or BFG, F1s, NOT E.T Streets or QTPs) before requiring a cage on newer vehicles like the Cobra and Lightning.

Anybody else hearing this??



VINNIE

 

No but I sure hope your right...

PEacE................

still dont help me...... I run SLICKS!!!!
I am sure it would help out alot of people though!

 

Who will be the first in the 10's on Nitto's or F1's?

 

when you say cage, do you actually mean a Roll Bar. I thought the cages are required for the even quicker vehicles

 

where did you hear these rumblings Vin?

 

VINNIE,

I hope you are right.....it makes sense, even to include radial slicks.

The tires we run on are much better than what was available when the roll bar rule was introduced. It would make sense to require a speed rated tire in the front that would have wear limitations.

They go much faster on motorcycles with no protection.

Jim

 

Not true. They have to wear a cup.

 

For us noobs, can someone tell me what the current rule on cages and roll bars is?

Actually, what's the rule on helmets also?

And actually, are there any other special rules for production cars that I should know about when I hit the track for the first time this summer?

 

ILLINI-SVT here is a great site for noobs:

Use the track locator to find out what is available.
Most of the tracks have a website. The regulations and any other quirky rules will be laid out not to mention, dates and times etc...

Once you zero in on a track/date casually post here when you are going. Maybe a non-noob will pipe up that they are going, you meet and secretly do everything they do right up to the last yellow light on the tree.

Then no one knows you was a noob.
If they call you a noob, 'deny,deny,deny'.

 

What I have found:

ADDITIONAL RULES FOR CARS RUNNING 10.00 TO 11.99 SECONDS
After market rear axles required for cars running 10.99 seconds or quicker.

All cars must have an approved roll bar/side bar and head protector sufficiently padded and utilize an approved 5 point quick release seat belt/shoulder harness. (SFl Spec 16-1, 3" straps, 2 year interval).

Roll Cage with window net required on all cars with modified firewall or floor panels faster than 11.00.

After market harmonic balancer mandatory on all cars running 10.99 seconds or quicker (SFl Spec 18.1).

Manual transmissions require an explosion-proof flywheel, clutch, pressure plate and flywheel shield meeting SFl Spec 1-1 or 1-2.

All drivers must wear an approved protective jacket (3.2A/1).

Arm restraints and gloves mandatory in open-bodied cars running 11.99 seconds or quicker.

No independent rear suspension on cars faster than 11.00

 

more....

CAR REQUIREMENTS—ET 11.99 TO 11.00 SECONDS

---All cars must have an approved roll bar/side bar and head protector, sufficiently padded; and must utilize an approved five point quick release seat belt/shoulder harness (SF 16.1).

A roll bar is required on all cars running 11.00 (7.00) to 11.99 (7.49) and in convertibles running 11.00 to 13.99 and in all dune buggy type vehicles running 12.00 and slower. See the NHRA Rule Book for more detailed information.

 

Thanks for the linky Raoul.

Seriously? Then that would mean don't bother building any 10-second Gen 3 Lightinngs when they arrive, huh?

 

no, you just switch it out, or just run once.

Might be one of ot those things thats more linient since i've never heard anyone switching out the axle?

 

This is the 2004 rules. I don't think the Gen3s will be out for some time certainly not 2004.

You wonder how the '03 & '04 Cobra's are getting by.

I know at the track rules are bent, broken and flat out ignored unless somebody complains.

Consider this, if you are going to run 11.99 or better a cage helps you stay alive if something goes wrong. In the long run it is cheap insurance.

That's why I'm having this done:
