ummm good luck getting that cars cage approved.

There is no diagonal in the main hoop which it must have???

i thought the same thing at first, but have a look in the cams manual, you don't need anything in the main hoop. all of his cages are designed like this, and they all have passed.

3.2.4 Diagonal member:At least one Each Diagonal member must be fitted. Its location must be in accordance with drawings 253-3 to 253-5 and it must be straight.

I and the people who cert my cages interperate that as each diagonal in those mentioned drawings must be present in the cage design.

Those drawings as im sure your aware indicate a hoop diagonal and a rear leg diagnoal minimum

Some of the basic cage drawings dont incorporate a diagonal but the way we read those rules it is required.

If his getting them through that way then oh well but personally id rather have a diagonal to stop the thing folding over.

253-3 shows the design he uses. main hoop is empty, and the brace is in the back of the car (double brace in yt's case). reason he does it is so you can store your helmates and stuff in the back between stages.

i'm not sure what the cams guys are like in other states. but ours live by those drawings, if you put extra bars in that are not in the drawings, the cage will be knocked back.

eg... this cage has 2 diagonal baces instead of a solid bar in the main hoop...not in the cams manual, and gets knocked back (yt had to cut bars the same as that out of a rally car the other week, cause cams knocked it back)

not being smart Risking but you should check those CAMS manual drawing numbers you quoted. drawings 253-3 and 253-3A neither have a diagonal in the main hoop, only in the rear section.

Ive just completed my own cage and for a first timer its fing way to hard to interoperate the CAMS manual to do with cages. i had 2 or 3 other people come and give me there opinion of what they though it ment then i went n building.

I was with Ben when we dropped his car off and i asked YT the same thing as i thought at the time that you had to have a diagonal in the main hoop. once you look at the cage an the way it is built you can see that its just as safe and better in a weight balance situation.

YT just did a cage for us for a r33. looks like he got his design ideas from custom cages, cause they are very similar.

very well made for a streeter i would have put the taxi bar on some bends and got the bars that follow the roof lining up higher and the a piller bars closed to the a piller but perfect for a race car where it doesnt matter if the bars are noticed

im not arguing, if he gets them through then great.

My persoanl experiance I had one rejected for not having a diagonal member in the hoop so ever since they all get it.

I guess its the same as front door bars like 253-17b. Ive got a cage passed with that straight leg cut and welded to the side intrusion bar. However more recently with my space frame it has been knocked back and the leg must be one solid bar.

Rules are open to interperation and every inspector is diffrerent I guess.

Thats cage design savman would not pass any of the inspectors I use either.

What are the costs involved with having a cage weled in ?

That's if you go with the "Custom Cage" kit option.

Thanks for your help.

Regards

If you are series contact one or several of the people doing them... they will give you a price based on your requirements. There are quite a few mates rates jobs done on Race cars in Tassie, and a forum is not the place you will get an accurate costing.

      I haven't....but a poorly made one would terrify me. Surely a good second hand one is the go, as they don't work hard and no-one wants to keep one after they are finished with it A big consideration would be the weight of the shell you are putting on it....is it a fully dressed chassis or just the body

      Not stock. All remade. Mostly looks stock because the pipes run to and from the standard holes in the inner guard to get to the return flow FMIC. I'm not sure which question you're trying to ask, because it seems like "stock position" vs "stock position".

      Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card style AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had no flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
