@Ernie Camp - Damn straight man!! That would be cool as shit. I would rock the hell out of it. You could just go Sound Paralysis Fishing for the Large Mouth Bass with the acoustics from the Engine. You just grab them with your net when they float to the top LOL 🤣.!!
I've been wondering about a blower on a modern engine. Everybody is going for turbo powered engines. I old school and enjoy the sound of belt whine with the blower. The torque curve is outrageous.
Old school blowers on modern fuel-injected engines like this is pretty much mirroring what the Germans did with their aircraft engines during WWII, and those worked stupendously well when they weren't starved for strategic resources (specifically high-octane fuels) like what happened later in the war. That's why the Germans were so interested in making air-worthy Diesel engines by the way. By that point in the war, the Allied forces had pretty much cut-off German access to high quality and/or highly refined petroleum products, so they tackled the problem with multiple solutions. Diesel engines for almost every application was just one of those solutions. Another solution was that they started making synthetic liquid fuels from coal and natural gas instead of crude oil. As far as I know, that's the first time any plans were made for large-scale production of synthetic petroleum products, and I'm relatively sure that research and development work done to enable that during WWII was part of the science used in order to develop modern synthetic motor oils. The only reason we don't use the same processes to make liquid fuels for internal combustion engines is that it costs more to do that than it does to just distill and refine crude oil into gasoline, diesel, jet fuel, etc. I bet it would only take maybe 10 years to get refineries switched over to making synthetic fuels from natural gas and coal instead of crude oil if the crude oil supplies were ever cut off suddenly or not-so-suddenly.
Prob one Of The most informative engine build ever.. a true old school mixed with new tech.. thanks for the video.. looking forward to more of your builds..
Found your channel subbed because the way you give the info and talk reminds me of the old hot rod TV shows my dad used to watch and I loved watching them even if back then I never understood any of it lol
I love Motion Race works. They have awesome customer service and are always there to help when I run into snags. They’ve saved me by staying open seriously LATE just to overnight me a part. Best guys in the business.
Not my first comment but it’s great to be giving all the measurements and spec’s. And learning about the LS upgrades because the only American V8s I have built were for Cup cars. I have a specialized shop and just work on BMWS and I still will go over to the race shop and use the equipment in the motor room to do stuff to the cars I’m fixing. When I worked at Jimmy’s I mainly did engine assembly and dyno them. I stayed in racing from 1994-1999. I had a great side business of working on BMWs when I worked there. After I got enough to build my shop I quit the racing world. I have tinnitus from being around all those screaming motors, only time we wore hearing protection was when wearing a head set when the car was on fire track. I can’t believe we were that dumb because all the old timers were usually def in 1 ear from tuneing on a race car. Now I’m in my 40s and ears ring like a bell.
That is a beautiful creation from someone who has a love and a passion for creating perfection in motion! To think that thoes pistons will be rotating thoes valves opening and closing all of thoes pieces moving at 3000 to 5000 revolutions and minute for hours on end for years of getting abused ran hard and left to rest only to get beat on for hours and year after year.... only the best can build the best
Might of been mentioned but shouldn't a belt tensioner push inwards after the blower pulley? Usually tensioners don't ride on the belt's teeth. They ride on the flat side of the belt as it is smooth. The current setup might also shake the belt even more by riding in the teeth and possibly cause premature wear.
This build is perfect, it's going to be super cool in an airboat. I love the look of old-school superchargers, if I had the money I would build the same thing
@@rondoanderson usually an alcohol fed smaller big block being revd to the moon. Typically a mid 460 cubic inch with a 14/71 blower being revd out to 7500+ rpm. Because it runs on alcohol it can do that for 2 minutes (or more) without overheating.
We do this all the time here in Australia just too do skids that's our stock standard go to build for a not to expensive burnout car build or some of the guys with big money are putting big blocks with 14/71 blowers 2500hp just to burn rubber and do it under 1min that's the aim of the game 🤜🤛🇦🇺
I have not seen a blower setup on something modern. It's been a really really long time but it goes to show you some of the old school tech can still do it with the right match ups. Nice job guys!
back in 75 my friend ran a 611 blower on a LS 6 small block one fast car but it was one expensive engine but he had sponsors pay for it pretty sure they owned the car he use to do a lot of west coast racing
Why is the blower belt tensioner tensioning on the cog side of the belt vs the smooth side? I mean the tensioner pulley is smooth wouldn’t it make more sense to run it on the smooth side of the belt? And maybe a shorter belt to reduce the belt slap?
Airboat seems like a perfect place to use turbo's rather than Roots blower. Propellers work most efficiently in a narrow rpm band where turbo's would be most happy to run....and the instant response from the Roots won't be as significant as with a car. Turbo lag wouldn't matter and they'd make more power at less boost with cooler intake temps. But I understand the owner wanted the visual impact of the Roots...and he got what he wanted in spades! One question: How long is that blower belt going to last flapping around like that?
22:30 shorter blower belt and idler pulley goes on the outside hence why its smooth.... I KNOW, EVERYONE DOES IT LIKE THIS... but its still wrong. even the tension on the idler arm is being hold with a set screw versus the other way it would be pressing in instead of trying to hold the belt out. less flex and way less strain.
Amazing build. Would meth be a suitable alternative to cool and lubricate the rotors allowing for a multi port injection system instead of the EFI system used?
BDS is great for an old school 8/71. The money is on The Blower Shop high helix with hard anodized case and teflon strip triple lobes. 60% more efficient than the original twin lobe. A blower shop 8/71 with intercooler could likely hit 1100 on pump gas with higher efficiency and cooler air.
and will need to be restripped adding maintenance and cost. The air for this will be really chill, since its a boat I would guess they would just pull in freshwater for the intercooler but I am not familiar with airboats.
I've been contemplating a build very similar to this. One of my questions is which crank snout do you use with this type of blower? Would the LS7 snout be best or just a regular dual keyed LS snout? The setup I'm planning will be similar but with a larger blower, more boost, and better heads. I plan on running the exact same intercooler too. This will be for a very radical street/strip car built for maximum effort with EFI. Please keep up the awesome work and keep the videos coming!!! Thanks!
Question on the blower belt routing. Why does the cog's of the belt ride over the tensioner instead of running it on the other side of the belt which is smooth? and you would get more cogs engaged to the pulley

Blower is even bigger than the entire engine. Insane job well done 👏.
The belt will always be the craziest part to me how much it can move and still grip WOW, guys Wow
It's cogged.
Yeah that huge belt flopping around is pretty crazy.
Watch the Australians doing there burnouts - those guys take blowing a LS to a whole new level!! This one you built is beautiful!!
And us Kiwis. Innovation is key. If you can think of, just try and do it until it works, to prove yourself right.
Would love to see a video on an old school style build with a roots blower with mechanical hat injection on a 540 BBC running on pump e85
look at every Aussie burnout car in AU but switch out the E85 for alcohol. They are all blown, mechanical injected v8s of all kinds
This engine builder guy was next level... I'm just amazed watching the craftsmanship.
I absolutely love old school roots blowers on LS engines. My dream is to one day have a setup like this in a drag car, if I can ever afford it.

Air boats are so friggen cool!! Those guys go insane with engine combos. Little flat bottom pc of aluminum with a blown 632 BBC. They sound awesome.
I run an engine very similar to this-Blown 408 Ford Windsor-In a 65 falcon Ranchero-Its a rocket ship! Did all the work myself.
Sounds like a fun ride!
God bless the man doing all the manual work there coming to an end!

Awesome Build! Did anyone else see a bit of belt slip on the overdriven run? Looked like it was riding up on the upper pully in some frames...
The belt did look loose to me also...

It was cool to see the boost pressure fall around the torque peak due to increased volumetric efficiency.

An air boat absolutely needs the instant throttle response that a roots blower gives. Turbo lag would SUCK on an air boat.
Intercooler is probably made of coopernickel. Same thing used in good geothermal furnaces.
Hell yeah motion raceworks I was literally going to comment if you guys can you them. By the way almost everything that comes from motion is billet
I would love to see a high RPM LS build maybe with solid lifters
Had to shut UA-cam down when they showed the beginners drag queen commercial. Cool video. Too bad I didn't get to finish it.
22:30 shorter blower belt and idler pulley goes on the outside hence why its smooth....
I KNOW, EVERYONE DOES IT LIKE THIS... but its still wrong. even the tension on the idler arm is being hold with a set screw versus the other way it would be pressing in instead of trying to hold the belt out. less flex and way less strain.
All that effort on a beautiful build.....why keep the coils on the valve covers?
Why not relocate down below the headers or basically anywhere else?
Probably more convenient
Nice build
Boost makes things better.
Amazing build. Would meth be a suitable alternative to cool and lubricate the rotors allowing for a multi port injection system instead of the EFI system used?

So what would this build cost s guy?
I think this would go great in my mkIV Jetta!
Looks cool, but that belt setup is not ideal. I would keep extra belts on hand. I'm assuming the crankshaft snout is upgraded.
Out in the swamp I think I'd want a pulley on each side of that belt to stop that radical belt whip.
That's and incredible well built engine
