S&W cages and NHRA

[Archer Fabrications]

Hey guys, I'm trying to purchase a pre bent cage and had just a few questions.

Is the chromoly cage NHRA approved/will it get approved? They say it's 1 3/4 .083 wall chromoly

But when i look at the nhra specs i see they are requiring different sizes of tubings? Is the fact that everything is 1 3/4 fine because it's still larger than all the other specified bars?

I just want to be positive I'm getting the correct spec of tubing.

I'm just getting the 8pt and I'll add to it as needed. But the goal is to get certified for 8.5 ET eventually after i add to it. Until then being good for 9's will suffice.

For those of you that do have this cage, did it fit well? I know they come over sized and it's cut to fit but I'm curious with anyones over all experience with it as well.

Also if anyone has any other suggestions of pre bent cages i can weld in I'm open to it.

I run their mild steel 6 pt and I was pleased with the fit. Just give them a call and ask them, they were more than helpful on the phone.

I don't know about chrome moly. I know it can be thinner/smaller diameter but needs 100% fig welded around perimeter, which usually requires tacing the cage in and cutting holes in the floor to drop it down, to allow the top to be welded. That or you cut the roof off. The fitment is much more difficult as when Tig welding, you can't have much of a gap when butting the tubing up. At least with mild steel, you can get it within 1/8" and just fill it in nicely, makes it look like you are still stacking dimes and get great penetration on the joint.

EDIT:

You linked DOM mild steel. Your NHRA attachment above is for 8.5 second chro-mo. I believe you just want a regular 6 pt roll bar (not a full sub 9.99 cage) like me. The S&W DOM mild steel is a great ROLL BAR (it is what I run) and is legal to 9.99 and up to 135mph. Fitment is great, I've done 3 so far. You can successfully Mig it in with a 120VAC 15 amp mig. Regular 80/20 gas and regular mild steel wire. Its a great first welding project. This is my AWD, I reused all portions except door bars from my old car:

I'm a tig welder so i got that covered. I have linked the correct cage. You choose chromoly in the drop down menu. I'm looking for thr 8pt and I'll use an X brace in the rear. I am looking to get certified for 9's right now. And then 8.5 after I'm in the 9s. When i add the halo and A piller bars.

Some of my stainless welds. To guce you an idea.

I mainly wanna know if this cage is NHRA legal. I already run 135mph traps.

NHRA is listing minimum spec. If you want to use a stronger tube then what they require, then you are fine.

I'd buy from magnus if they bent the cage. But I'm going weld it myself.

Just buy the main hoop in CM and 6x6 plates and 20 Foot Long Tube. Have someone bend the harness bar for you and the ends of the side bars to the floor to plates.
Call S&W and ask them to make the main hoop wider

 

[Archer Fabrications]

How much wider? I habe 6x6 mild streel plates, i dont need CM plates do i?

steel plates and just double check the measurements. I dont remember off hand on a 2Gen. If I remember right they are 2 inches off on each side. also have them NOT cut the bottom of the main hoop because they cut it short

 

[Archer Fabrications]

Looking for this sort of a design. X brace attached to a strut bar welded in.

With the front bars and main hoop to look like this, but i was t planning on a low bar parallel with floor like I'm this pic.

checkout Franks White 1Gen DSM. and Just another thing. Some tech guys want a bar on the floor over trans/DS tunnel but NHRA says FWD.

You do realize that the 8-pt roll bar you've posted is only legal from 11.49-9.99 and/or 135mph right? You keep saying you want to be good for 9s but you have to go with a full 10-pt cage to be good for anything quicker than 9.99 or 135mph. The 10-pt cage is good for 8.50s. There is no in-between certification. It's either 5, 6, or 8-pt for up to 9.99 or 10-pt for up to 8.50. Skip the 8-pt and go with the 10-pt, especially since you say you already trap over 135mph. With the 8-pt you'll already be out-of-reg.

Fair enough. 10pt it is. Thanks for clarifying.

What is the beat way to go through dash or around dash?

 

[SonySlave]

No problem! Just didn't want to see you have to buy twice! The listing has a drop down for "through dash" or "around dash". Also, don't forget that you have to have a window net going any quicker than 10.0. S&W offers a mount kit and net on the order page. I'd recommend picking that up at the same time.

Is that a through dash kit? Was avoiding pulling dash at the moment .

dash needs to come out if you are going to add the dash bar and if you dont go in front of the dash "looks like shit anyways" you will need to cut your dash . Are you planing on racing a Nrha event ??? I dont like one job holo from s&w.

I wanted to have the option to be NHRA legal I mean, why have a cage if it isnt certified? Especially if i do events. definitely will be attending a shootout or two and the 3794HTA is a big fella


I'll see what marco can do about bending me a good fitting main hoop. maybe mr white horse can get a discount? Lol

They dont care at the shootout. Shep was running 7's without cage and friend was running 9's without a cage

Just tell tell him you need the whitehorse price

 

[Archer Fabrications]

Really?? Interesting... I always hear about tracks kicking people out for no cages. They do at my home track pacific raceways allllll the time. Thats why ive even been looking into this.

I have a cage for my own safey. cops around will tow your car if they see you have a cage. because if you hit your head on the cage you can kill yourself. they dont seem to care about the rollbar

Yep. Check out the videos and pic from the shootout.

 

[SonySlave]

The Shootout is a track rental and is a major exception to the rule. You only need the driver safety gear at the Shootout: helmet, fire suit, etc. depending on how quick/fast you are. Just check Buschur's rules on the High Boost Forums or the Shootout 2014 thread here on Tuners. Pacific Raceways has always been a bunch of tech nazis! That was my home track as well before I moved to Maryland last year. Buy the proper stuff to be NHRA-legal for real events outside the Shootout.

I have seen that but Here is the funny thing about the shootout. The NHRA Tech guy. Said this to me. NHRA doesnt care if it is a rental or not. If a Track wants to be a NHRA Track that track must follow there rules 24/7 So I dont know.

I know that's the rule as well. I have never understood how Buschur gets away with it. Either way, my car is caged and NHRA-legal whether my competitors' cars are or not. I've seen too many bad accidents at the Pan Americans, WCF: Imports vs Domestics, and other events, even test n tunes, to not have my safety gear.

 

[nitrouskris]

On another note. I have been to tracks were the tech guy says car isnt legal. so I pointed him to the NHRA Sticker and He said he didnt care. So I call the NHRA Tech cellphone and hand the phone to the track tech and he tells me to go. I always have a rulebook in the car. because lost track tech guys dont know shit

I with you on that. the problem is most DYI guys and shops have know F'''ing clue about how to build a cage for a car. See Lutz Fab car on YB. There was a very know DSM car on here that when they show me the car. Not One thing was legal on it. But the tech guy give them a sticker thru the mail.

You're right about some of the tech guys for sure. Especially with imports. Some just look at you sideways and don't know what to do. Haha, I'm WELL aware of that thread on YB. Ridiculous!
