Video: 30 Years Ago The Stirling External Combustion Engine Was Tested By The Government – Where Did It Go?

We’ve heard of the Stirling External Combustion Engine before but we never knew that they were not only built but also used and tested by the US Government, specifically the Department of Energy. These “external” part of the engine means that the combustion is not happening in the cylinder but rather outside of it. The heat from the combustion is used to move the piston. Weird? Hell yes it is but according to this video, which is admittedly slanted in favor of the potential manufacturer of the engine, the thing beat any and all expectations. It raised fuel economy, exceeded emission standards without the use of a catalytic converter or other device, and gave trouble free service in a multitude of different locations and environments.

If there is ONE part of the video that raises an eyebrow it is the fact that the narrator says that the tchnology exists to put the engines into “limited production” today. We’re not sure why they would be “limited” in their production but there are a few potential reasons. The first would be advanced and complicated machining, thes second would be construction from hard to find materials that are not easy to source. Outside of those limiting factors we’re not sure what the blockage was with these. We’re also not sure why the government did not move forward with more.

Either way, this video is cool because it shows off the testing and talks about these engines being used in the real world, something we never knew happened!

Tre5 Customs OBS Chevy Feature: Red On Red On Red On Red…

Image
This cool truck feature from Tre5 Customs is an OBS that just about everyone can relate to. Yes, the fit and finish is high level, the chassis is rad, and the LS swap is on point, but overall this truck is still identifiable as an OBS, with only one body modification! It still has door handles, features some sport mirrors, and other than a welded in roll pan out back doesn’t have any body mods. It’s just as the general intended, only smoother and prettier. Check out the details in the video below. As we’ve said before, the guys at Tre5 build some pretty cool trucks, and I always like watching their feature videos that come along when a project is ready to get delivered to the owner. These aren’t super sexy videos that make you ooh and aah over the truck but never actually tell you what is in it and under it, these are videos that really show you the cool stuff that went into these builds! We’re talking about the details and info that real enthusiasts want. And while these trucks are t

Check Out This 6×6 Engesa EE-25 Army Truck And It’s Freaky Boomerang Rear Suspension In Action

Image
Army trucks, we love them. Why? Well for the same reason we love functional hot rods that are lacking in amenities but are heavy in ass kicking ability. No matter the country of origin you are typically not going to find a lot of cushy stuff in an army truck, especially a large one. They are loaded full of ability, though and that’s exactly what caught our eye when it comes to this Brazilian 6×6 Engesa EE-25 and its awesome Boomerang rear axle. The truck uses a walking beam style layout but it can articulate in some incredible ways to keep the rears planted while the rest of the chassis rises to some pretty steel angles. Quoting a story on the rear suspension: The suspension of the EE-25 utilizes live axles and leaf springs, the rear suspension having a conspicuous “Engasa Boomerang” walking beam, a feature seen on several other Engesa 6-wheeled military vehicles. This suspension articulates, allowing the EE-25 to traverse large undulations with greatly increased traction, handling,

FAST LSXR INTAKE TEST-IS IT WORTH $1000? HOW MUCH HP DOES IT ADD? LSXR VS CHEAP, JUNKYARD TRUCK INTAKE

Image
One thing that sucks about modern EFI engines like the LS, LT, Mod Motors, And HEMIs is that aftermarket intake manifolds for them tend to be really expensive. It’s understandable as there is a lot of technology going on in there and the manufacturing is way different than the typical cast aluminum intake manifold. Some of these intakes cost around $600 but some are closer to $1,500. The question is whether or not they are worth it. In truth, we know they work, and work well, but whether it is worth the money or not is going to be up to you. In this test video from Richard Holdener, who has tested more LS intake manifolds than anyone on earth, he’ll show the real results of testing this hopped-up 5.3 with a stock truck intake and a FAST LSXr. Video Description: LOW-BUCK, CHEAP, JUNKYARD TRUCK INTAKE VS BIG BUCKS FAST LSXR! HOW MUCH POWER IS THE FAST LSXR INTAKE WORTH ON MY LS? SHOULD I BUY IT FOR MY STOCK 4.8L OR 5.3L? FAST VS TRUCK INTAKE-WHO WINS? HOW MUCH POWER IS THE INTAKE UPGRA
