My Winter Project....

[HiImBrian]

^Hes got a good point. Any new pics of the brackets or the finished rear? I can't wait to see the thing one the wheels are all mounted!

[JET]

Is the tube frame mild steel or chromoly?

[EvilEvo]

All the tubing is chromoly. It needs to be to meet SFI 25.1E.

I should have some good pics sometime this week or weekend of a rolling chassis and body.

Another reason I couldnt really do much of the load testing is the way I stuck all the piping together. I did it in a way that none of them are technically connected in solidworks.... that way I could make a parts list with lengths and even print out the coped cuts for each pipe should I want to.

Hopefully the FEA will at least isolate the major stress concentration areas so you can address those.

That's the problem; they're rather complicated. I plan to send them to Advanced Design Concepts in Pewaukee.

Where is this thread at?

[EvilEvo]

There were two threads that they got pissed.. the first one was thier own thread in thier forums on Evo M. They deleted half of thier posts and almost all of mine a few days after. The other thread was this one which they also had most of thier comments removed:

Reading that thread really intrigues me, considering the amount of time you have invested in this entire project, why do you publicize everything? Since you don't have the financial resources that many shops do (as stated on EvoM), you can be sure that people will be copying your work. When I get the CAD models of the parts I'm having scanned, there is no way in hell that I will even think of freely giving them out. I'm sure that I'll selectively give them out but that's it.

On a side note, what is your background, Aerospace Engineering?

Are you using Oxy/Acet to do the preheat and cool down? I have read through the process several times but I haven't done it yet. My cage is chromoly, so I will get to play with it whenever I get around to putting the cage in.

[EvilEvo]

On thin walled tubing you dont technically need to stress relieve the welds. I preheat the tubes just using MAPP gas to sweat the pipes. Once all the welding is done I will use an oxy torch and heat crayons... mark the pipes around 1" from the welds and start ocilating the torch heating it up evenly.

The chromoly does crack if you attempt to weld too hot, or too slowly. If you dont shield it while its cooling it also tends to crack. Im sure you already know this but it needs to be welded with a Tig Welder. You wont need all that beafer of one for a simple cage.. All you really need is around 80 amps and make sure you have some sort of pedal control or hand control for the heat input. Use ER80D-S2 filler rod and pure argon for the shielding gas. The Tungsten is the red one.. I think it is 3% Thoriated (Which is also radioactive I believe so dont eat it or something)

The reason I publish this stuff is because I dont care.... it is my hobby. I dont make money at this and if I do someday then perhaps I will keep more of it secretive... I never posted the actual cad files and it would be extremely difficult to copy the exact specs... could you get it close, of course.Then again go on Ebay and buy one of Marco's intake manifolds for half price. Once I sold 5 of them someone would tear it apart and copy it if they thought there was a good reason to do so.

This is just my hobby... I will make a header and intake manifold for myself. If I decide to maybe Ill make a few extras and sell them. I dont ever plan on making this a money making career though... if I get a few hundred bucks every once and while cool.

My background is confidential.








(Just kidding)
No Im not an Aerospace Engineer. I get paid $9 an hour working at a sign company. I was the General Manager of a few companies a few years ago. I moved back to Winona and now work for the great wage of $9 an hour. Now you see what I meant when I said I lack the financial backing as most people have. Want to give me a job?

[EvilEvo]

Here is an extremely rough draft of the front end...

My guess would be mechanical. Hard stuff, that's why I changed majors. lol.

[JET]

What exactly do you do with the crayons? Was that just for marking? Or are you putting that on the weld to shield it during cooling? I have the TIG covered, I have a Miller Sychrowave 250.

[EvilEvo]

The crayons arent actually crayons.. they are heat markers... they will melt at a certain temp. That way you know when you have heated it enough.

[Pushit2.0]

Looks like fun, do you know what tranny/rear end you are going to use? 2speed glide and a ford 9?

[niterydr]

Fun looking project, good luck once again getting it going.
I honestly wouldn't have attacked the big dogs with your dreams and aspirations while only owning a partially caged Evo, but that is just me. I hope you can contend on that level, it would be really cool to see a local, self-sponsered vehicle to pull it off.

Just curious though. How large is your guy's shop down there?

[EvilEvo]

It is definately something to kill boredom. And the only people I really made fun of was AMS.. I defended Buschur and I gotta say I like the guy. And hey, racing is a competition after all

Just enough for 4 cars to be worked on reasonably... you could probably squeeze 7 or so if you really wanted but you couldnt really work on them at all. More of a big garage then a shop really Its cheap rent and is big enough for our personal cars so it works.

Sweet deal. Let me know if you need anything.

[EvilEvo]

Got any 4202Rs with the Tial Housings sitting around you wanna loan out for the season? :P

[niterydr]

No, only thing we have instock are a few 70gtq's and a 4202 currently.

If you haven't shopped around the turbo manufacturers or big retailers yet, I'd bet you could get a turbo sponsored with the promise of some magazine coverage and attend some big races. Building something that nobody else is currently doing attracts sponsors. You might get stuck with some shitbag like Slowboy, or you might actually get some good sponsorship, it's worth a shot.

[AJ]

Shit, we shoulda asked for magazine coverage before this thread went up here. LOL

Steve's got a point though, seems to be the way to go is trade coverage for products vs cash, even if you get you hands on some product you don't always use, sell it for some funds to use on other racing expenses.
