NHRA rule change

[8306gt]

True Street correct? I wonder if they were more lenient on you guys.

When I tech'd in Friday, they looked at every one of my SFI tags....

Our local track will not let you run without a roll bar sub 11.50.

I ran True Street yes, but I actually teched in with the other guys down by the scales which I thought were NHRA ispectors and not NMRA however I could be wrong about that. He asked me about SFI items, such as balancer, flexplate, jacket, helmet, all of which I have and then told me I was good to 10.0, technically however my car wouldn't be covered by this rule as its an 06.

Gotcha.

The difference with your car is if you have the SFI tag they are going to keep you to that standard!

I've talked to 2 local track tech guys about this so far this week & both are telling me that the nhra is very clear on the "unaltered" part.

from what they are telling me, nhra's stand point is unaltered means 100% stock, period.

no d/r's, no nothing, other wise its buisness as usual, 11.49 you'll need a cage (well a 6 point roll bar if you want to be technical, around here most folks call anything legal a cage, again around here, a roll bar is something the exhuast shop whips up after work to throw into the bed of an old pick up to mount lights on)

I guess we'll all find out next year how they choose to enforce it, either way mines going to the chassis shop after the holidays since I mainly bracket race the car & have no intentions of slowing it down so with a street class cut off of 12.0 I'm forced to move into the modified class.

at my home track there are plenty of modified class cars in the 8's or better so my reasoning is that I at least want to have a chance of surviving if I was to (knock on wood it will never happen, but better safe than sorry) get collected up on the other end by one of those guys.

I know NHRA was basing their roll bar rules on Unaltered Chassis, not the rest of the car. Other rules were covering aftermarket power adders and such.

An unaltered chassis meant no modifications to the firewall, floor pans or roof structure (ie carving out for weight reduction or tubbing) .

It is ambiguous but I'd hope they mean that here ... I do agree, once you get over 120, you need a roll bar and 5-pt harness.

I agree the unaltered comment means completely stock. My chassis guy was discussing this with the NHRA inspector that certs his cages and he said that is how they will handle it at NHRA tracks.

Also, They are going to really crack down on high 9 sec cars with roll bars instead of certified cages. Mine is going back in this winter to make the 6 pt a Cert cage.

I can't answer what "unaltered" truely means in this case as no-one seems to know.

over the holiday I spoke with another tech guy from a somewhat local track though & he assures me that his reading as of now is a 100% stock (in his own words, down to the air in the tires) car, unaltered in any way, period.

he will continue to enforce the 11.49 cage (everyone local has always refered to a 6 point, 11.49 rollbar as a cage, so I use that term frequently although I realize it's local slang) rule for any mods what so ever, even d/r's.

Typical NHRA rule change. What could be written with one sentence so that everyone understands it will take months and several more announcements from Olympus to get everyone on the same page.

NHRA Amends Roll Bar/Cage Rules For ’08-Later Street Vehicles

A lot of safety advancements have also been made to vehicles since the original 11.50 roll bar rule was put into place, keep that in consideration as well.

I am not one to skimp safety though either, but 11.50 is out dated thinking with today's tech on new vehicles.

 

[fdjizm]

Alot of people thinking this is awesome news must not be reading the part where it says "unaltered factory car", so if you think you're going to take your modified 10 second car out to the track with no cage you're in for a surprise.

 

[Mike K]

It also says 08 and newer. I wonder how much they will enforce that year cutoff.

 

[fdjizm]

IMO this change is for cars like the new gt500, the gtr, the zr1, some exotics etc... so owners can take them to the strip UNALTERED and run their car. People who own these cars will be grateful for that but I'm not sure why people with modded cars are getting excited about this change it doesn't even apply to them.

 

[stkjock]

Bone stock to the tire..... otherwise you'll need a bar

also the rule seems to apply to a specific NHRA "Street" class only

 

[Unreal]

If you have an 06/07 that is the same as an 08/09 and you put 08 on your tech card do you think they are really going to check the registration to confirm the year? I guess this will all depend on the track and the inspectors.

 

[Seer]

I'm thinking this is more responding to the GT-R and ZR1. GT500 is going to need tires to hit 11.50 with any form of consistency. To be honest, it is probably more in reference to the GT-R as you see them racing a lot more in street classes than any other vehicle that would fit this description.

I'm not counting the Z06 out, but on street rubber, you usually do not see an average driver getting one passed mid 11's.

 

[mrnoodley]

I doubt that "unaltered" will mean factory tires. Do you expect the tech inspectors to know the OE tire on every car made? Just my guess, but I would think that any DOT tire would be considered a "service replacement".

I'm not even sure how you define a DR in a rule, treadwear rating? That's how SCCA does it.

most DRs are labeled as such, any tech guy worth his salt should spot that right away
