What is this? I don't know. And MTI doesn't know, either. Not only does MTI handle fabrication of parts for their racing efforts and for their product lines, they also contract machine for outside firms. This is some kind of thing for a company that makes armored vehicles (the kind that carry money). MTI has no idea what role it plays, but they are happy to precisely and accurately machine parts for anyone who can provide the engineering drawing. It’s a “don’t ask, don’t tell” kind of relationship that works nicely in this situation. And, if you want, one of their mechanical engineers can provide the CAD drawing, too.
One of the last things I expected to see when I walked into a shop known for Corvette racing was an AMG Mercedes G-Wagon head. There it was, being prepped by Austin Ivester for a fully-built life of 900 supercharged horsepower. MTI not only does engine work for their own client base, they build motors for a number of other shops throughout the country. Their expertise certainly helps everyone.
Want further proof of attention to detail and expertise? Take a look at the crank for the G Wagon. While already a true piece of work and sporting an AMG logo from the factory, MTI spends a ton of time balancing and machining the crank to be able to support huge power. They found that, with the load generated by the blower, a more robust harmonic balancer was required. This meant a larger keyway in the crank, which you can just see in the front of the picture. These guys are no joke.
But, even with all the fancy-schmancy computer controlled stuff, sometimes you just can't beat turning something manually on a lathe. Here, David Thomas is working on a thing. What is it?
It's actually a fitting that is being used on this jig, that MTI also fabricated in-house. The jig is used for assembling C7 Corvette harness bars that MTI has engineered and fabricated to fit in the new Corvettes without any interior panel modifications.
