This block of steel is about to become the first ever CTS-V Billet Diff housing!!

What makes you think there is gonna be more then one (if that)?

Won't get that far

[darkman]

I said "if".

[STAGEUP]

I doubt anyone on this board has a CTS-V that can bend the future steel case.

I've looked at doing this for the last 3 years,I've yet to find a way.Cutting is really no problem,just time consuming.The material is the problem,shit moves around like crazy,especially when you need heat treating.Theres a reason they use cast metal guys,it stays straight,it will not bend, it will break from shock.Maybe if these guys are carefull and hog all the excess meat off this forging,carefully heat treat the case,and then finish all the I.D. bearing surfaces,maybe,just maybe they get a usable piece.No friggen way they could ever make a buck selling them here.That square chunk of recycled shit cost more to make and ship than what I want to pay for the case.But hats off to these guys for having the balls to do this,I wish them all the luck in the world.I'm not flaming here at all,just telling it as I see it.Randy

Make it out of the strongest, most flexible, lightest metal........................UN-OBTAINIUM !!

[sideways_v]

I seriously hope you guys are successful at this. If for no reason other than to just prove the nay-sayers wrong.

Mild steel doesn't have a high enough carbon content to respond to heat treatment so what you see is what you get. I'd have chosen 4130 chrome moly.

*4230

I find it interesting that this particular thread is kinda' providing "expert" advice on how to proceed with the project. (Almost in a negative light)

But......these guys are the ONLY ones from what I can read that are trying SOMETHING.

Give 'em a chance to succeed (or not). IMHO

I think the important thing here is that even if the mild steel experiment fails, valuable lessons can be learned and applied to a different material.

For the record: I hope you're successful. If it fails the first time, you've got most of the work done and it just comes down to choosing materials.

[CTSV_Rob]

My post was not meant to be negative but just a question about possibly using different materials.

I work in a machine shop as well and one thing I have noticed is when you mill out that much material it will put stress into the part. For large pieces of SST (even Prodec) we usually rough cut the material then send it out to have it annealed to remove any stresses that the initial maching may have put into the part. Once annealed then you can do the finish cut.

Not sure how much the metal will move when you heat treat as I do not have alot of experience with this process.

As with anything that is machined it is a learning process and when you figure it out you will have the "recipe" for making that part successfully. I'm sure there will be a couple of surprises and I sure hope you push through them. Once you have done it, sell the final product but don't give away the recipe, you should profit from it.


Good luck to you and I cannot wait to see the final product.

Build it, you won't regret it. When I started my twin turbo project, there were a bunch of guys trying to give their "expert opinions" on what I was doing wrong. Most of them probably drive bone stock cars and wouldn't know where to start if they wanted to do their own mods. You'll have bumps in the road with this projects, but with some perseverence this will be an awsome project. Besides, getting there is half the fun.

YUP YUP.



I am curious what type of steel it's made out of. Somehow we leaped to milt steel. In this post CG, indicates its' 4140. Perhaps CG or Nutz can chime in the metal type.
