Roll cage advise

[VooDoo]

So It is if your going over 135 mph you gotta have a nhra approved cage regardless of times. Question is are there any bolt in cages that are approved or will this be a custom fab issue. I think i read Duane got booted for not having a cage with his last run. I still want to be able to get in and out without having a bar across the door opening.

ANY ADVISE?

Thanks

Bolt in cages are for show, weld in cages are for racing.
look on S&W race cars for the cage you are looking for, then have it put in (will need minor mods IIRC)

get the kirk racing cage it has better fitment and more options than the sw cage.

however ultimately i still recommend a custom cage over any of these off the shelf cages. never go cheap on safety equipment

Kyle speaks the truth boys and girls. Safety is not something you go "bargain" shopping for.

I've seen Kirk Racing online before, but their web page is terrible. Anybody have any pics of their cages installed?

I agree 100%. I know our strip is a NHRA sanctioned track and I will be able to get it inspected there next event. Whatever I do it must pass inspection. THATS my concern. If it dont I wasted $ on something that is not gonna do its job.

if money isnt a concern, i would def suggest going chromoly. its twice the price but atleast 1/2 the weight.

also i've never seen any of the bought cages that didnt have to be tweaked and notched, but easier than a full custom cage. not a lot of people around that know how to build a certified cage. its more than welding some tubing together.

lastly, if you are getting forward bars id get a swing out for the driver side. may not be necessary for you, but i'm a tall guy and it isnt a lot of fun to squeeze over the fixed bars.

What about putting a cage in a targa car? wouldn't it interfere with the top?

Careful with this info Dave. Chrome molly weighs just as much as steel tubing, but its stronger pound for pound than mild steel or DOM, therefore you need less making a lighter cage.

Also, when requesting a chrome molly cage, request to see the welder/fabricator's welding skills. Chrome molly is very easily over heated if not welded properly.

In regards to chromoly: http://www.dragracingonline.com/burksblast/ix_9-3.html
Mild steel or DOM is cheaper and every bit as strong without the issues.

Putting a cage in a targa car is easy and has been done many times as well.

Cheaper yes every bit as strong definitely not.

Pound for pound, no, but if properly made it's every bit as strong. It wouldn't be allowed if it was inferior.

You really should think twice about saying some things.

Cages are not all rated the same. And yes inferior cages are allowed to run slower times.

Tell me again, if it wasn't as good, why is it allowed?

With all due respect poo you're so effing wrong it's sick! Chrom is about 2.5 times stronger in everything...yes a mild steel cage works but it's not near as strong as a chrom cage made exactly the same! You're a mod and should know better than too spout off ignorant comments

Cause mild steel works....but as strong it is not...chrom you can have a lighter cage that is much stronger than a mild steel...not everyone has the bank for chrom! Come on poo this is simply retarded you're agruing this!

you are basing this off something that is vague?

You have only reading comprehension and google to guide you.

Would you like me to do a stress analysis of chromoly tubing vs mild steel? I do have access to the testing equipment.

It is allowed yes, but beyond a set point you need to have chromoly.

Does not mean every bit as good as.

Read the links posted and know the facts. Chromoly is downright DANGEROUS if not properly welded (and the risk of this is very very high, if they're having issues on top fuel dragsters, you think you're going to have your cage done perfect?).

As in the link I posted since you fools don't know how to click

The wall thickness spec is higher on mild steel and it's going to be heavier. Nowhere did I say anything about "made exactly the same."

Reading comprehension owns another one.

Also conviently missed my first link...
