Episode 189 of Mike Finnegan's Garage will help everyone who's building their own turbo kit at home, especially if they are trying to fit twin whirlybirds inside of a small engine compartment. In this video, we show you how to pie-cut straight aluminum tubing to create the tightest 90-degree bend possible. We'll also show you the tools we used to make it happen. Also, here's an update on the 21ft Eliminator Daytona jet boat build and some new technology for you jet boat guys! This one is heavy on the tech and also features the one and only Mike Cotten behind the ol RU-vid Starter Kit aka his smart phone! lol
Want to support our bad decisions? visit www.fsmgarage.... and grab some of the new merch. We guarantee it will keep you warm on a 90 degree day!

OMG! Finn, Dave and Cotton you guys are awesome! Jet boat content is the greatest. I’m 54 and grew up on jet boats! My dad was one of the first to have one on the river here south of Chicago in the 70’s. Once everybody saw what he had and how fast his 72 Sidewinder went with a big block 455, everybody wanted a jet boat! Within the next 2 years the majority of the guys were getting jet boats. My dad has been gone 20 years now but you are helping me bring back all the memories from then. Thanks for posting your jet boat content!

@frankrotello8938 2 года назад

That innovation at the jet nozzle is genius. I work with pump systems and once I saw it I was like.. oh yeah that will work. I also noticed that there is an inducer on the inlet of the impeller as well. They should all help with hole shot. In Fluid terms low velocity head. By using both devices you increase your suction head which reduces cavitation. It should give you a very quick and smooth transition. Thanks for showing us that. I had a few river boats back in the day, most used the Hamilton 212, the Am Turbine, and the Kodiak 3stg.

@sjorsdewit9394 2 года назад

great video! i realy like this solution and you guys did a great job showing hot to do it. but if you want a bit more flow you can also cut the y tube from the turbos a bit further back, make the round cut on the 90 ovalized and weld something like a 3.5 inch or even 4 inch 90 to it. right now the 2 turbos are pushing a lot of air trough that tight small 90 and that risistance will also make a lot of back presure resulting in a lot warmer exhaust temperature. cheers! cant wait to see this thing slapping cheeks in the water!agag

@95Sn95 2 года назад

A quick tip for anyone out there that doesn't know for aluminum you don't need a metal chop saw you can literally use a regular wood chop saw with a quality wood blade and you can use a wood router on aluminum wether its pipe,tubing ,channel whatever ... Sounds crude and dangerous but it's not you will be surprised how quick and easy aluminum cuts with wood blades., I work at a large custom fab shop and we use these methods quite often, one thing always wear PPE like glasses face shield and don't skimp on hearing protection high speed tools are ear damagingly loud! One plus is a quality wood chop saw usually has very accurate miter adjustments compared to most metal chop saws especially budget abrasive saws. Fyi DO NOT use any high speed wood cutting equipment on aluminum that doesn't clamp the material i.e. table saw or circular saw, it would cut through the material no problem per SE but where a table saw can fetch up and send wood flying at super high speeds with aluminum binding is way more likely probably definite and metal or blades flying at bullet speeds it would be life threateningly hazardous .... Do not use a table or circular saws not even in a pinch!

When you are working with aluminum angle or flat stock.

I am an old worn out fart who started out in automotive right out of hi school mainly because I could not afford any college, so I did what I could to support my wife and children, first one I had while still in hi school. I never missed a child support payment and left 3 x wives way better off than I was. Just a word to all you young men. Do not short change yourself, and put something away for your 'golden years' (my ass). Before you know it , your days of racing and toys will be way behind you an your body will be as worn out as a super t-10 with 5000 passes behind a well endowed big block. You will grind and clank and pop out of gear 20 times before you reach your front door most days. You will not believe what all your tools will fetch at yard sales or online.

17:00 there is one more way that's accessible to anyone with a 4 ton press and enough skill to carve out (or have carved with a CNC) two wooden molds, and that is to press two halves of the elbow, and weld down the seam center after clean up. You can bend most alu in 2 mm flavor with just those. IMO, also gives a clean finish product. If you have access to a CNC (one of the small, wood and light metal types) you can even go one step further and do reductions into the piece you're pressing, alu is easy to bend (with enough lubricant, of course). Any 2~3 ton bottle jack and a half decent frame can do it.

It's all about "fluid dynamics," and in this case, it's gas or air but the principles are the same........ decrease volume and increase pressure (& velocity!) If you have a 3 inch tube with 10 psi of air pressure passing through it and you decrease that 3 inch tube to a 1 inch tube, the psi of air pressure increases not quite to 30psi but close (and it's travelling much faster!) I hope that this makes sense?

@AndyFromm 2 года назад

@@scottykify agreed

@scottykify 2 года назад

Technically, the smaller diameter of the tube raises velocity of the fluid flowing thru it and turbulence increases with higher velocity. So I'm not convinced all the small diameter tubing bends and transitions are the BEST "due to increased turbulence". But it might not be that bad either, specially with a intercooler and plenum to straighten out the flow down stream. There's allot of really fast cars out there with very tight bends on their turbo plumbing.
