Custom front steel bumper?

[Ludachris]

Oleg, I'll help you bleed the brakes regardless man. Just PM me or give me a call.

 

[Ludachris]

Chris - Check out this front bumper on this 2G race car. Maybe something like this would be good as well. If it was on a race car, I think it would be pretty good. There is all kinds of room there. Well, more than what we are working with now. Just another idea man.

Well, you guys caught my attention. I am currently a second year engineering student out on a work term right now. Sadly I won't be able to do any analysis on the stock bumper untill I return in the spring due to lack of programs (and a bumper). However I was thinking about this same "bar" style bumper for a little while now. I still have access to a CAD program on my laptop and wouldn't mind actually trying to come up with a solid engineering standard drawing to help some guys out.

My only problem is I don't have a dsm to use to get dimensions and such off of. Unless someone feels like being my eyes and hands, it might have to wait untill spring/summer when I get a chance.

Idealy I would like to do with a 1g first (as that is my main project), and even something with a fairly large intercooler to make sure it accomidates this.

My initial ideas were square tubing, bolting to factory bumper shocks, and also utilizing the factory bumper mounting hole locations (90-91 style bumper). this is also something I was hoping to brace in a few points for added strength, but location is to be determined without solid pictures and dimensions. That is just something off the top of my head though, I am very open to suggestions and opinions of other crafty tuners!

And if anyone actually wants me to pursue this I would be more than happy to. My nights are now pretty boring without a dsm to play with

I'm not quite sure what that upper bar is doing but yeah, nice design. I'll talk to Pagosa DSM about making one or three of something like that. He's been wanting to build a light weight bumper for his car.

Shure would be fun to smack into something with it at 5mph and test it out before using something like that on a DD.

I dont think that would be too hard to fab up. Do you??

Not sure what it is there for either. But Im sure it serves some purpose or they (race team) would not have put it on you know? Not the best picture of the entire peice, but its about the best one I could find.

I really like the bar idea. especially the one off the race car talon. they even thought about up high so if you run under another car your OK.

But another thought if it would be feasible would be to fill the stock bumber with AB foam then cut away the metal you did not want. Something along those lines would be super cheap. I have a couple of extra bumper support or at least access to them if we want to try it chris.

Now that the shifter kart is sold I am going to have to get my roadracing via DSM's now.

Good call there. I didnt even think of that one. Good design then.

 

[KGB Pilot125]

I was thinking today that if someone is going to be making this you should add a tow hook to it. That way its mounted solid and if you get buried in the kitty liter you can get pulle dout with out losing any body work.

Any thoughts on a rear bumber?

I'd like to do a rear bumper too, but first gotta get this one figured out. Need more weight savings in the front of these heavy beasts.

Would be nice to get some measurements off the DSM race car I posted you said you liked Chris. It's for sale, Im sure whoever is selling it would have no issues taking some more pics of the bumper and some measurements as well. It doesnt look all that hard to fab it up actually, if you know what you are doing.

 

[Ludachris]

Do we have anyone in the area that can go over and take some measurements? Better yet, do we have anyone here that could just buy the car?

Nice. Well if I had the axtre 15K just sitting around, I would finish my car I'm sure someone is in the Tampa area that wouldnt mind doing it. I believe thats where the car is.

p.s. - I E-Mailed the guy that is selling the car to see if he knew the measurements or would measure it for me. I will see if he responds to the E-Mail.

No, that doesn't offer any real crash protection. The goal is to have something designed that is lighter than stock, takes up less space to allow us to get more air into the radiator, and still offers crash protection. Aluminum bumpers won't work. We've come to the conclusion that a round bar, similar to the type and size used to create roll cages, would be the best solution. It's just a matter of having one designed.

Those would be fine for drag racing though I'm sure.

 

[architechnik]

At the very least, the dejon option is not even welded at that center section. I wouldn't trust it against anything and assume it would not crumple inward quite quickly. They do say in their description that it offers NO protection.

I like the round steel, but I admit that I was thinking about the foam filler option or using some lighter square steel that could be molded then filled.

We kicked around those ideas earlier and it seems to be that the round "roll bar" type design would be the easiest to fabricate. Being you can just bend it easily and not have to have a lot of welds as on a square peice of material trying to make it fit in a rounded area. Also, the round material is less space concuming than the square material.

 

[KGB Pilot125]

chris,
tube benders arent that expensive (i would like to own one anyway) and I have a 110 welder that can at least tack weld maybe we will have to get together and hack up the front of my parts car for fun. We can tack them then have scott over at Mac finish the welding. I can weld and it would be strong but it wont be pretty.

Harbor Freight Tools i wouldnt use any of these to make a cage. But it should be able to handle these simple bends.

Guys, I am Currently designing exactly what your looking for.
Not more than a week befor Ludacris started this tread. I started designing a crash bar for the front of a 2Gb Talon. which if my measurements are correct, will bolt directly to Any 2G front end, While still alowing enough clearance for even the largest of 4.5" cores and fitting very neatly inside or below the upper portion of the bumper cover. after the 2g bar is made. I will hit the Junkyard and cut off what ever I may need to do a 1G bar.

I will tell all the details , As this is a very simple design and anyone with Fab skills can make this. Im NOT trying to get rich!

Just Like was shown on Page one.
Its Full Tubular Mild Steel. which wraps around the front of the car, and supports the upper portion of the bumper cover.
As the Stock bumper did, In one solid curved bar for Exceptional crash protection.
and yes It will be as Light as possible.

This is the 2G bar! I know the 1g is completly different!
We are Starting the Build with 1.5" OD. 3/16" wall thickness on the main crash bar. now the actual tubular mounts that will bolt to the stock bumper tounges will be smaller at 1" OD. with a 1/4" ID, to fit snugly agaist the mounting Bolt.
to crush these bars you must 1st shear the 1/4" bolt or Rip off the bumper tounges. before hitting the intercooler, or other parts of the internals.

what will happen is you will knock out the tiny 10 mill, nuts that are tack welded to the tounges, and use the Existing 1/4" holes to drop the mounting bolt through, and simple screw on the Nylon lock nut. simple effective and very strong.

Im kicking around the idea of Powder coating these in 3 colors or simply painting them with Demkote. In red, black or silver. considering on 75% or more of our cars, these bars will be seen in front of the upper portion on the intercooler.

Im just really busy with my Talon and S-10 Builds along with work ATM. so these are on Slow burn!. Gimme some time or make your own as I detailed above.

Doug - Thats great man. Post up some pics when you get one all done and mounted as well as the process if you can. Would love to see what you have going on there. Keep us posted.

 

[KGB Pilot125]

Doug,

Any updates?

 

[bmoha2]

DOM tubing would work great! Overbuilt sounds nice but the purpose of this front bumper support is to collapse under a stronger impact and pull the strut towers in to absorb impact; To not deform (modulus of elasticity) below or at 5mph and then turn into your front "crush" zone in a harder impact. Possibly 1.75" DOM tubing with a slight radius to it?

 

[4pistons]

Since it won't be seen, rather than trying to bend the same radius as the bumper, you can make saw cuts or pie-shaped cuts (NOT all the way through) and bend and weld the proper shape. If you're a good welder it should be just as strong as a gentle bend. (wasn't he a grizzly bear??? )

I've used this method for frame connectors and crossmembers on other cars and it works well.

Bumper update..

Almost none to say other than a few measurements and some tack welded mockups... But so far I am under 12 pounds of materials. which could be reduced ALOT by refining my Tubing wall thickness and switching over to chromoly.


I'll Try my best to get something together and fully functional ASAP!
But Please be patient with my bumper build, or Do it yourself
As work has Swamped me, to the point I cant even finish the build up on my car, So I am back to driving the S-10 Its fun and all. but nuthing like the Talon!

Chris, Erron and I have been running exactly what you're talking about for quite some time. If you would like something custom bent, welded and ready to bolt on just let us know and I'm sure we can get one together for you.
