For safety, run the bars. Bars can always be removed at a later date. What you could do is add a plate on the driver's side of bulkhead, bore a hole in the middle of the plate. Run the tube through the bulkhead plate to the towers. That way if you ever have to remove the forward part of the tubes, you could cut them from the engine side of the bulkhead and towers and the driver's compartment would be unaffected. You would have to trim the tube close to the bulkhead and cover with a small patch. Remember to weld up the tube to the bulkhead from inside driver's compartment.
This procedure affords a little more protection in the footbox area due to the fact the bulkhead is also attached to the forward tube. |
Here is a link to the cage I just installed in my car. 10 point.
http://www.torquecentral.com/showthr...017#post253017 This was my first cage install I think I did pretty good. I would post the pics here but they are to big for this forum. |
What diameter and wall thickness did you use? I guess this is for drag racing? Clean fit! :bigthumb:
|
Thanks.
it is 1.75 DOM tubing with a wall thickness of .134 The .134 is because it has to be certified and the minimum is .120 which tube is not uniform so you may have areas that arent .120. Yes it is for drag racing. |
That is quite a weight penalty to take for using ERW tubing. If you went to DOM, you could have used .125" and had plenty of extra material thickness for the .118" rule.
Could have saved more by using the 1 5/8"x.125" for main cage and 1 1/4"x.125" harness bar. But, if you are not trying to get the FD as lean as possible, it is ok! Still, nice job! Keep up the good work! |
It is DOM tubing. Not ERW. The extra thickness of the walls is no biggie probably adds a a few pounds.
Also the small main hoop and harness bar I could have gotten smaller but: A) I think it looks better all the same size B) It is easier to fit it if they are all the same size C) The bends were already made I just fit them and welded them in so I didnt have a ton of choice. The car is VERY light, probably one of if not the lightest FD out there, short of tubing the front end or backhalving. |

I have been waiting for the engine to get here for the past year so I could finish her. Car has been mini tubbed, relocated leaf springs inboard, left room for the biggest drag radial tire made with 2" clearence for a bigger slick if wanted. Engine is a bored and stroked poly head 318, I think CID is close to 350 now. Engine dyno'ed with a sigle 4 barrel at 440 horse at 5500rpm. Project HP's is around 500. Has custom pistons, rods, cam. Has dual carb custom sheet metal manifold, custom headers, 727 trans with brake. Has 100 shot of Nos, all the bling a new car should have. Installed new Dana 60, disc brakes all the way around. Finishing interior now with a custom Aluminum dash inserts and a full console. All electrical is in the console except lights for the dash guages. all replated interior chrome, new cage, all new glass and will have leather interior. I gutted all heavy parts such as factory dash pods and lightened up the bumpers, hood and deck lid. Car was extremely over weight. When I am done I will post some pics. I'm pretty sure that engine has a 3.79" stroke crank so it's 369ci at .030" overbore. There is a dual quad intake and 2 nitrous plates for the motor last time I checked. Glad to hear the motor is finally running. I guess Mr. Ross got some work done. Speed Raycer (Scott), Ah, ha! I know that car! Mopax wouldn't kick me to the curb. I'm one of the original 10 or so members. I still have my '72 Swinger that I've yet to drive so I'm not completely without a real Mopar ride, other than my '72 B300 van that is. I'm having a house built and once it's done I'll be able to get back to work on the car. The car has a little B&M PowerCharger on a mild 360 that I haven't even fired up. The car has good shocks, springs, sway bar, etc. Once it's driving and the paint and body are done it should make for a nice driver. |

Josh,
350 or 360 what ever, it was dynoed originally with a single carb and of course no NoS. Dick hasn't done anything with it. It has been over at the "Garage" in Vancouver, USA. Dan Maples has gone completly through it, needed new pistons and rings. Has a new Sheet metal fabbed intake and a matched set of high dollars custom Holleys and some extras you have not seen yet. Should have it here in a week or so. LT1RX7, It is DOM tubing. Not ERW. The extra thickness of the walls is no biggie probably adds a a few pounds. I am not bashing you cage, looks cool! I was just adding a little critique offering others interested in Custom cages a little knowledge so they know they have some options. |
No Bash taken.
Huh, I thought they said it was DOM but I looked on their site and it didnt say anything about DOM so I guess you are right. Oh well no biggie, I am happy with it and what it cost as long as it is strong enough to pass tech and save my life I am happy with it. I knew DOM was more consistant. How much weight do you guess I could have saved with DOM tube? |

found these pictures on an old disc, thought I would share!
Last 2 Camaros the City of Portland purchased for Police cars, both are used in the Traffic Division. Marked car is obvious, other car is a All Black with hidden strobes and lights inside car. Car is totally invisble and used for being sneaky. |

Russ... Why the two different rear brace mounts? Keeping the black car stealth/sleeper? Very nicely done on both!
|
Stealth! They have all the windows tinted and didn't want anybody from the backside see the bars when the interior lights were on. All Police cars do have bars, so it was important to keep them tucked and hidden.
Thanks, by the way! |

Hey guys, doing a RX7 cage for a customer. Working all day on the rear, lucky for me my Daughter wanted to help. Nice to have an energetic 11 yr old around. She did all the measuring and help cut the material. Thought I would show a few pics, remember, this is in its infant stage and is still dirty and not final prepped.
The rear is attached to a 10"x8" plate attached to the shock mounts and the crossmember piece just forward. The lower "X" is attached the forward member and the rear support tubes attached to the spring perches with an 1/8" flat plate welded to all of the bars in the configuration. Really stiffens up the whole rear area and ties it all together. Will add more when I get the front half installed with door bars. |
Great work there.. makes it easier deside how to do it on my own.. =)
|
I want to be able to do dimple-die work like that between some of the tubes and the chassis, like on the A-pillars.
Are the tools expensive, or is it hard to do? |
not to expensise, but make sure your class allows it. If you are roadracing they consider it a attachment point not an gusset. Any other form of racing should be ok. I made mine, most only work for sheet metal, not .125" plate. I use a press and it works awesome.
Can buy them from Mitler Bros. in North Carolina in all different sizes. |
Wow Russ... that's some pretty extreme tube work on the back of that car. I guess if you want to get the springs and shocks tied into the cage you gotta do it. I also noticed that your welds look a bit more professional than mine... very pretty.
BTW... I ran my car thru tech for both SCCA and ICSCC and the cage passed with flying colors... no complaints about anything. It trophy'd twice so far in RS class at Pacific Raceways. |

I believe it's www.mittlerbros.com |
You are correct, I was thinking of Irwin-Smith, they are in N.C.

I have a few more pics of the 84 I am doing, going slower that I would like. Fitted the dash and a-pillar bars yesterday. Today will be door bars, cutting of door and refitting dash and components. Damn A-pillars bars in the 1st gens curve out away from the a-pillars bars, Really annoys me. Most other cars are straight or curve in a bit. Really like to try to keep everything tight to the lower kick panel and a-pillar with only 1 bend in the tube. Oh well, can't be perfect ;) all the time!!
I really must apologize for the quality of the pics, if I only new somebody that was an accomplished Photographer! |
