Subaru Huckster: 862hp 4WD Monster!
 

No need for the HP but I like the vintage, angular styling -- let's presume not based on a current production model?

Then again, I liked the Subaru XT6 back in the day. :party0030:

I like all the active aero. Pretty funny and badass.

I am sure it is fine, but some of those welds in that cage look terrible.

Looks good to me :iono:

I work in manufacturing, so stuff like this stands out to me. Like I said, it's probably fine, cages are hard to weld. Just looks like poop even with PC over it. Looks pristine compared to some of the fab work on the HKS TRB-03 GT86.

Probably mild steel cage that was MIG welded for cost/speed :iono:

Probably seemless mild tube. You would mig a cage, tig would be wrong application. Just body positioning when welding a tube with a bunch of other tubes coming into it would suck. It's not like a small object where you can just move it so you can be comfortable and have nice access.

TIG is what is used with chromoly cages, and many people use TIG to do mild steel cages. Having done both TIG and MIG, putting a MIG gun into tight spaces is not fun. Same for TIG, but the torch is smaller and easier to reach tight spaces, but it does require attacking the weld from both sides with the filler rod and torch. The heat is easier to manage, and the welds are better quality, but the time is night and day different, which is why I think they went with MIG for this, as it is for function over a show car, and it is so over-powered, chromoly is not needed.

Chromoly is a totally different beast then mild steel. I don't work with many welded chromoly parts, just machined shafts out of 4140 that we have case hardened. TIG on mild steel is a waste of time unless you are working with thin tubing, and even then it's kind of a waste. You TIG for a few reasons, a big one being heat control. Chromoly is sensitive to heating and cooling so you TIG it.

Edit: Really any high carbon metal you want to be careful of heating and cooling when you are bringing it within its phase transition temperature or you start ending up with bad grain structures.

I forgot who I am talking to, better cover all my bases :D

Yes you can mig chromoly. You just have to take some extra precautions and should probably try to normalize the weld affected areas.

Judging by the rubber on the pavement, there were several takes while filming Pastranas video. It must be a nightmare getting cooperation from the municipalities to do those things.
