Forced Induction Differences - THE SKID FACTORY - [ Quick Tech]

Today on The Skid Factory Quick Tech, Al Explains a few different types of Forced Induction and how they work including a Turbo Charger, Centrifugal Supercharger and a Harrop Eaton Roots-type Blower.

Thanks to Harrop Engineering for supplying us with their Display / Demo Blower to show off how they work!

"It's pretty hard to talk about boost and not be emotional" NEEDS TO BE ON A I know I would buy a few.

[DEBOSSGARAGE]

Thanks for the link guys! We had fun with that engine!

"Get in that comment section, and start yelling"

HAHAHAHAHAHAHAHA

I can't believe you said those things about those things! My mates cousins next door neighbours father inlaw had a big huffy boy on his V8 and it was by all accounts super awesome. Or so i'm told. Also i saw a video with one and it made my thing go schwiing.

Al, it looks like the trip to New Zealand has had a positive effect on the tidiness of your workbench!

[Baksteen_Express]

Even though there is almost no new stuff for me as far as the knowledge about the tech. I still like watching these videos

Hey guys, another great video, thanks! I fitted a Rotrex C38 Centrifugal Charger to my Euro BMW M3 (3.0l) a few years ago. I kept it on standard internals, so needed a good and reliable method of governing boost. For a finish I ended up using a Tial wastegate (yes, you read that right) just after the compressor outlet to bleed off boost. With this setup, I also have the advantage of being able to use a smaller pulley to get to max boost lower in the rev range. Why not just turbo it? Well I don't have the skills (or desire) to race a laggy pig and its a bit of a PITA to fit a turbo on a RHD M3 of that era. Ultimately the setup works really well, it has been extremely reliable and it's really nice/predictable to drive... which all adds up to relatively pain free motorsport!

just bought a centrifugal supercharger for my xr8, turbo will make more power, but the simplicity of literally bolting it to the front of my engine makes it a good option

[tiporari]

Straight talk. Application matters. There is no perfect solution for EVERY scenario.

[mrcaps]

Love your channel. I had a 2004 L67 Calais. Swapped to a smaller pulley for extra boost, water to air intercooled, roller rockers, otr intake, pacemakers, 2 into 1 exhaust, plugs and a tune....reliable and fast....brilliant.

[oldbloke]

Back in the day I owned a 1985 Atkinson truck with an GM 8V92T Diesel engine. It had a huge turbo on top of the blower. It also had a water to air cooler under the blower so its nothing new. You explained it well.

[madmotorhead]

I love the roots blower whine more than the choo choo of a turbo or centri. good video

[jamesw]

Al is very pleasant to listen to, just laid back, facts, no BS, Thanks

[nathanshobe]

As per usual Al is spot on. The only aspect I'd expand upon is that in some forms of circuit racing twin screw is quite popular because it provides a very linear response naturally which is much easier to tune around, versus needing dynamic traction control strategies or boost by gear. On a road course, and extra 10% power mid corner isn't always wanted more than predictable linear response.

[garrypeterson]

Love the show guys, I would like to see you guys do a twin charge application, Supercharged and turbocharged.

[KENARDO]

The only thing I feel is worth noting is, modern engine management solutions often have the ability to limit boost on launch, making turbochargers suitable in those high-output drag applications. Obviously Al and Woody are already hip to that, but _Youtube Comments!!_ Great summary on the tech boys

[tomhyde]

Please do an episode on TIG welding, your choice of settings and strategies.

have always been a turbo man. driven a few centrifugal supercharged cars and was never a fan and positive displacement supercharged v6's lick massive balls and in most cases do drive better without it but after driving an car with an LS3 and harrop 2300 runnin about 14psi i've gotta say the torque is addictive af.. so much so i'm pretty sure thats the route i want to go with my SS now.. perfect for a street LS. no doubt i could make more power with a turbo but being realistic for a street car a turbo 6 litre LS even on 9-10psi boost makes stupid power that you can very rarely even try and use on the street and when ya do it doesn't do anything anyway cause ya just peel tyres so maybe i'm just getting old or something but i don't see the point anymore. 3/4's of that power with big torque right off idle where ya can actually feel it is fun as on the street. i still say on anything other than a V8 its must be turbo'd but. supercharged 4's and 6's= aids

[deeze]

Hahahah, seeing Al saying "Choo-choo boi" got me laughing so hard dunno why :D
