Just wanted to make sure..

 

looks the same as my car

 

yes, that is an acceptable way to do them.

 

that is how i do all my cars...

 

that is legal

 

So the bar that goes across the floor board is just additional then?Our local NHRA tech official, that certified my cage, said that isn't required, and he hasn't heard anything about it being added to the rulebook either????

I know on here I have heard conflicting things, but this is from the guy that certifies all the chassis's around here for NHRA.

 

yes


thats how may bars are

 

Its not in the rules yet but it will be.
I just had my car done the same way.

Says who?? No disrespect, but I would think that the NHRA officials would know of this rule change if there were plans on it being enforced??

I just haven't heard of anyone, other than just people on here, say that it is going to be enforced.

 

Thanks for the replies. I kinda half posted this as a joke because of all of the conflict about the way they should be done.. We did it with the extra "sill bar" just in case my local chassis inspector wants to see it that way. Its turning out nice so far!

 

It is not in the rule book that we get. The nhra officials have a much larger, more detailed book than we do. I saw the book with my own eyes when I had mine certified. It says that cars without a frame must have a bar going from rocker panel to rocker panel to a 6" plate and that the d-bars must be connected to them(the d bars are actually the two smaller bars that go down twards the center of the car). If your official usually does framed cars and hasn't had this brought up to him, chances are he has never read it in the book. I think that is why some wind up getting through and others don't. My offcial almost let it go. He said, "There was something about those d bars in a unibody car. I'd better go check the book." That was when I knew I was gonna have to add the bar. Anyway, here is a pic of mine before and after it was added. The second pic is after it was certified:

 

BTW- you can actually mount the hoop on top of this new bar if you want to. That is jus hard to do after the hoop is already mounted to the floor. My official was actually in the process of building one for his son. The bar went from rocker panel to rocker panel and the hoop and the d bars went to it. I wish I would have gotten a pic of it.

I'm having a cage put in right now. I already had a bar and this D-bar issue is the only thing I'm not sure on. When you say the book we get what are you talking about? The reg. NHRA rule book or the NHRA SC book? I have both and haven't scene anything saying these D-bars are needed. The same inspector who did Carey's will be doing mine. If he has some different book than the racers what page is it on? Our inspector does the top fuel and funny car chassis here in Indy. He is very sharp and has to be on top of things and he is passing these cages without a D-bar. So if you have some proof I can look at with my eyes that would be great. Not saying you wrong or right! I just trust my eyes over everyone else's

By the way Matt the cage looks good! I'll post some pic's of mine as soon as it is done.

On another note. I like the way the D-bar looks compared to just running the bars to the floor.

 

Note for clarification - "D" bars are the two diagonal bars that run from the main hoop down to A) plates on the floor (old way / usually accepted way) or B) an additional cross bar aka "Sill Bar" (new way / better-safe-than-sorry-way).

Thanks!

 

So if we had to change it and you already had it ran to the floor plates do you guys see a problem with putting plates on the rocker stills and doing a 3 piece pipe so basically it will have both D bar types.

the book that is issued to you when you join the nhra and the rulebooks you see online don't have this rule in them. the nhra officials have a more detailed book that we do not have access too.i didn't right down the page numbers, but i saw it and he read it to me. i don't know how else to explain it. just build it like mine and you won't have to worry about it.

Well i tried to get Mike to do mine this way, and Jack was there when I was asking and both of them said it wasn't needed.....

So you'll have to talk him into it....haha

The book you get is the book you follow. I dont understand the reasoning behind a tech inspector having a rule book with differant rules then what is issued to the general public.

It's not needed until the NHRA comes out with a rulebook that says it is.

 

If you really want to get techincal about your cages, just do what I did, and buy the SFI plans. If the cage is built to SFI spec, NHRA will accept it

Oh and please don't pm me asking for copies of the plans, you can goto http://www.sfifoundation.com and buy them. I know most of the chassis builders I know, all own sets of each SFI spec.

 

Why would you build an SFI cage if it's not needed??

My street car won't run 8.5 or 180mph so why waste the money/time? That's why there are rule books and you build your cars based on this.

Just my opinion, if someone wants to put an SFI cage in there street car, more power to them.
