Making Formed Carbon Fiber Parts At Home! This Is Super Cool And We Want To Do It!


Making Formed Carbon Fiber Parts At Home! This Is Super Cool And We Want To Do It!

We’ve featured Carbon Fiber fabrication videos from Street Bandito before, but this one is cooler yet. The process for building this small part can totally be replicated for something bigger, and other than the materials there are no special tools you can’t acquire pretty easily. This part is small, more decorative that structural, but ends up really nice and strong and is the first part he ever built himself. I dig it, and this video just makes me want to try it in my own garage. I’ve already been thinking I need an oven for the new shop in case I want to powder coat small parts or something, but this just cements the idea that I need it. An oven, a vacuum pump, and some materials and you are good to go. This is fun looking stuff and with the availability of resins and materials nowadays you can make virtually anything from Carbon Fiber.

What do you think? Would you try this at home?

LT Asks: The Actual Cost of Turbocharging a Big Block 8.1: Should I have built an LS instead?


LT Asks: The Actual Cost of Turbocharging a Big Block 8.1: Should I have built an LS instead?

I’m a big fan of LS engines, and they are all the rage, but some people can’t stand them because they ARE so popular. Some think there is no other engine on earth that can compete with them. I happen to be a fan of horsepower, so I know there are a lot of great platforms for making it out there. With that said, I’m a Chevrolet guy to the core so I tend to lean towards Big Blocks, LS, and small-block Chevrolets. I own all three, in different vehicles, and I have plans for building at least one of each in 2021, including a possible turbocharged big block for a tow rig build. So you can imagine my intrigue when I saw that LT had a new video out with details on the costs involved in his turbo 8.1 build.

Keep in mind, that this project is a work in progress and that this 8.1 has had very little upgrades to the stock engine, as it will come out later and be built to make 1,000 horsepower to the wheels. So don’t confuse this with a build designed to see how much power you can make before it breaks. This is not that, and in this iteration it has very low boost.

Here is the description from LT. Watch the video and see what he thinks.

Everyone wants to turbocharge their car or truck, right? But the real question is what should it cost. If you can buy a turbo kit for your car or truck, the answer is simple, but if you have to build a one-off kit, the answer can vary widely but in this upload, I’m going over the real, out-of-pocket costs that I spend on Uglytruck. The second part of the discussion is should I have stuck with the 5.3 LS that was under the hood originally or was it worth my time to swap and turbo the 8.1?

News: Mercedes-Benz and Nvidia Join To Redefine the Auto


Strategic Partnership To Develop Future-Proof Cars

Mercedes-Benz, one of the world’s oldest and most-respected premium automakers, is taking a big step into the future by partnering with super chipmaker Nvidia to create a new generation of software-defined cars. The plan is to embed a high-powered processor to power the software of all Mercedes, starting in 2024, allowing original software to be updated and new software to be downloaded, creating what potentially could be a 20-year-old car with state-of-the-art technology inside.

Starting in 2024 Mercedes cars will have a new operating system

Ola Källenius, chairman of the board of management of Daimler AG, joined Jensen Huang, founder and CEO of Nvidia, to make the announcement online today. They said this “perpetually upgradeable machine” will offer “endless possibilities” to the customer, eventually ranging up to full autonomous operation, and open up a new business model for the automaker. The companies added that thousands of engineers in Silicon Valley and Germany would be dedicated to creating updated software and new technology for the cars over the life of the vehicle.

The chip that is the foundation of this new system is the next-generation Nvidia Drive AGX Orin, which will have multiple processing engines for high-performance, energy-efficient computing and artificial intelligence (AI), and will come equipped with an array of sensors. It will be capable of processing 200 trillion operations per second (TOPS). As Huang described it, the chip will “solve problems that ordinary computers can’t solve.” It also is designed with built-in headroom “for things that haven’t been invented yet.”

Of course, for automakers 2024 is right around the corner given the timeline for new model development. For chipmakers like Nvidia, the development cycle is shorter, but in this case the chip is “still being designed.” The commitment promises a long-term involvement and further growth even after initial deployment. The joint vision of the companies is to offer “the ability to automate driving of regular routes from address to address” as well as deliver additional safety and convenience applications.

The New Car Business

In some ways this is a traditional automaker trying to catch up to a disrupter, in this case Tesla. The Palo Alto electric car maker has taken a different approach than incumbent auto companies, eschewing annual model changes (or even designating annual models), minimizing redesigns, but utilizing over-the-air (OTA) updates to add new software and features to customer’s cars. The most recent example was an OTA software change that extended the range of Tesla batteries to more than 400 miles on a charge.

The Nvidia chip that will power it all

When asked about this, Källenius deferred talking about a competitor, but noted that all new software from Mercedes would have a safety focus, be fully tested and meet industry standards, a not too subtle jab at Tesla’s pattern of rolling out beta versions of its software (and hardware) for use by customers.

Huang said with the advent of the 2024 Mercedes equipped with this new technology “the definition of a car will change forever,” with the newly purchased becoming the “starting point” for what a car could be.

Källenius added that the concept of “updates for the life of the vehicle” moves the automobile closer to the “iPhone on wheels.” Since Mercedes, working with Nvidia, has already created MBUX, the automaker’s proprietary infotainment systems that incorporate AI, this is logical extension of that relationship.

Mercedes is not worried about this new approach to automaking changing its sales cycle, although Källenius admitted it could impact things. In the same way this is a reinvention of the traditional automobile, he said Mercedes would need to continue to reinvent luxury in order for new vehicles to appeal to new buyers. In the meantime, older vehicles would be serviced by “engineering angles in the background” to keep customers allied to the Mercedes brand.

Changed Relationships

Not coincidently, I’m sure, Mercedes announced earlier this month that it was putting its joint work with rival BMW on autonomous vehicles on hold. Källenius said the major difference between the two German companies was a matter of timing. It seems clear Mercedes-Benz is ready to move ahead more rapidly.

The Perpetual Upgradable Machine

He also clarified the most recent direction from the company on its autonomous vehicle technology. While Mercedes had been working with supplier Robert Bosch on robotaxi concepts, Källenius said the company now believes full autonomy will first appear in its heavy-duty trucks used in hub-to-hub operations.

Similarly, Nvidia said the Mercedes relationship was not exclusive and the company would continue to work as it does today with a variety of automakers.

Nvidia engineers will be writing code and Mercedes engineers will be working on the first vehicles that will incorporate this new system over the next three years. Mercedes said it will roll out the Nvidia system as new models are introduced, but significantly that it will cross the entire product line, pointedly not a feature exclusive to the high-end models. It looks like cars of the future will be tied to the cloud as much as to any dealership on terra firma as auto companies continue their move to become mobility companies.
