Old School Repair: This Dude Welds A Crankshaft Back Together Like A Boss! It Was Broken In Two!

If you watch videos from other countries, where guys are doing repairs that would seem nearly impossible without modern tools, you start to appreciate and understand what our grandparents and great grandparents were doing to make similar repairs. It’s a true testament to how good something can be even without CNC machines or what have you. In this video, the only equipment used to fix this completely snapped crankshaft is a drill press, a stick welder, and a lathe. The lathe isn’t anything new, but it does seem to work well, and the guy using it clearly knows what he’s doing. But the lathe could be 50 years old or 5, it’s all the same.

Watch as this guy cleans and machines each end of the broken pieces, which might actually be from two different crankshafts, slides them together, indexes them, and then gets his arc welding on. He then straightens the crank, machines the crank, and finally drills the oiling holes in it and then sends it on its way to be used in some truck or what have you. It’s impressive and you’ll dig it.

Dyno Proven 500 Horsepower Combos: Three Stock Bottom End 5.3 LS Combos That Will Make You 500 Horsepower Or More.

I get asked about LS engine combos all the time, and the overwhelming majority of them are from people who think that they need to build an engine with all aftermarket parts. When I ask them how much horsepower they want to make, the vast majority say something like 450 horsepower. This makes me shake my head, because making 400 to 500 horsepower is simple and doable if you have a 5.3 LS that runs. Stock they make 350 horsepower, so anything you do from there will make real power improvements. A camshaft and headers will make over 400, and when you combine an intake, heads, etc, there are real power numbers to be had. And then there’s nitrous! Okay that’s another video, these are completely naturally aspirated combos that are based on a stock bottom end 5.3L.

Check out Richard’s combos, dyno results, and more in the video below.

Video Description:

HOW DO I MAKE 500 HP WITH MY 5.3L? DO I NEED FORGED INTERNALS TO MAKE 500 HP WITH MY 5.3L? CAN MY 5.3L MAKE 500 HP WITHOUT BOOST? WHAT IS THE BEST CAM TO USE ON MY 5.3L? WHAT ARE THE BEST HEADS TO USE ON MY 5.3L? WHAT INTAKE SHOULD I USE ON MY 5.3L? CHECK OUT THIS VIDEO ON THREE (3) DIFFERENT 5.3L BUILDS THAT NOT ONLY EXCEEDED 500 FLYWHEEL HP, BUT DID SO WITH THE STOCK BOTTOM END (STOCK BLOCK, CRANK, RODS AND PISTONS). ALL YOU NEED ARE THE RIGHT HEADS, CAM AND INTAKE (WITH HEADERS) AND YOU TOO CAN REACH THE 500-HP MARK.

Valvetrain Tech: If Light Weight And Low Reciprocating Mass Matter So Much, Do Stiffer Valve Springs Cost Horsepower?

Roller rockers, roller lifters, beehive valve springs, lightweight valves, lightweight locks and retainers, and the list goes on. These are all things designed to aid in controlling valvetrain at high rpm and under extreme power levels, and they do this by reducing the load required to move and control these components. So it would make sense that lighter valve springs would also be good for that. After all, anyone that has built an engine before knows that spinning the engine over by hand is very easy when it is just a short block and gets harder as you add components. If you have an engine with no spark plugs in it, and no rocker arms, then it is still really easy to spin by hand. But when you also have to turn the valvetrain, it becomes much more difficult.

So if you had an engine that didn’t “require” heavier valve springs, because it wasn’t going to be run at high rpm or didn’t have a camshaft that needed the extra valve control that heavy springs provide, would it make more horsepower with lighter weight springs that the others? Logic says yes. Or at least it seems like it does. But what does the dyno say?

Luckily for us, Richard Holdener knows because he’s done this very test and here it is so you can see for yourself.

Finnegan’s Twin Turbo Jet Boat Finally Hauls Some Ass! Watch Out World, Mike Is Going 130 MPH Now!

If you’ve been following along as Finnegan and Newbern thrash on projects, you know that the giant Hemi headed big-block twin-turbo jet boat has been fun but also a bit frustrating. The thing runs great, makes stupid power, and Finnegan has got a handle on the tune, but the problem has been that the boat runs out of water pretty quick and can’t accelerate for long enough to actually make a full drag boat pass. If you can’t get enough water into the jet pump to keep it fed, then it cavitates and stops pushing the boat forward. There are a few ways to get more water into the pump, which Finnegan has gone over on a couple of videos, but while each adjustment has made the boat better, it just hasn’t gotten it working well enough. Until now.

Yep, they’ve made some more adjustments and they are finally all working together and this thing is starting to haul ass!

Unfortunately, those adjustments required a grinder. As if the hull didn’t have a big enough hole in it already? Jet boats have a giant hole in the bottom of them, which is a little un-nerving when you think about the fact that holes in boats are usually not a good thing.

Mike will explain, so watch and enjoy.

Car Hauler Rebuild And Remodel: Windows, Kitchen Design, And More! This Thing Is Going To Be Rad!

Everyone wants one of those big giant toterhomes with the huge stacker trailer and all the fancy stuff that goes along with it, but most of us have zero shot of actually being able to afford something like that. I know I’ve considered buying an older gooseneck car hauler with the intention of building a nice and efficient living space in it that would still allow me to haul a car or two to the races. Well Emily and Aaron are doing just that and if you have missed any of the previous episodes, just click the link below and you can watch from the beginning.

In this episode new parts are actually starting to go into the trailer including big new windows that will make the bedroom area super nice. There will be no doubts that everyone will be jealous of their cool digs at the races. In addition to the windows, there are also new parts coming in and the kitchen planning is turning into kitchen construction. This isn’t an ultra fancy build, but it will definitely be cool, comfy, and useful. They are putting lots of thought into how each element will be used and that’s cool to see.
