Episode 40: Air Jacks and Air Jack Stands on Perkins V8Supercars

[@glensgraphix]

Thanks for posting these videos Jack. You do a great job being a one man show. I always look forward to the next episode. New workshop looks pretty good too.

[@perkinsengineering]

Cheers thanks Glen!

[@Dazm229]

I’ve always loved this feature in our touring cars. It’s a unique feature and something I wish I had my road going commodores. Thanks for showing the detailed work behind the set up.

[@perkinsengineering]

No worries, cheers!

[@davidlemottee2063]

Thanks Jack, I really enjoy the detail of how a V8 Supercar works. To date Ive been relying on the a number of NASCAR based channels who detail how their cars work. Please keep the content coming.

[@brendannunya77]

Fascinating, thanks for sharing mate.

[@perkinsengineering]

You’re welcome

[@niallk9336]

I like the supergt ones. They stick it in, lock the air, and detach the hose/source. You're left with just the lance to pull, also makes it easy for them to jack it onto wheels and move it into garage when there's an issue.

[@perkinsengineering]

Yeah they are cool!

[@dougobrien2840]

Thanks for Sharing How it all works Jack ,Would love to see your dad,s current projects .Always loved Larry,s stuff and ideas.

[@perkinsengineering]

Yeah hard to keep up with LP and his projects

[@rupie78]

I enjoyed that video Jack. Always wondered how the cars got up onto that second stage stand when seeing the cars at the track or on tv. Thanks for that and keep up the good work with the videos 👍

[@perkinsengineering]

You're welcome, cheers

[@deanehill9730]

Another informative demonstration. Thanks for the video.

[@perkinsengineering]

Cheers!

[@davidewhite69]

first time I saw these on board jacks was at Bathurst in 1984. The British Mobil Rovers had them

[@perkinsengineering]

Sounds like the right vintage

[@scooter0958]

great video Jack, really good to see how the air jacks work and to understand how you would get the car so high to work on safely. cheers mate

[@perkinsengineering]

You're welcome, cheers

[@christophercullen1236]

That was very interesting.

[@perkinsengineering]

[@TheSilverMuleTribute]

Nice work JP. Would be good to see a little video on how the jacks are attached to the cars during the build.

[@perkinsengineering]

Hard to see as they are fabricated into the chassis, would need a bare chassis in build stage to do that properly

[@ianbertenshaw4350]

Great video Jack ! I wonder if there is a specification for how high the jack has to lift the car off the deck ? If not then I wonder if any teams ever tried to minimise the lift to save a bit of time - only micro seconds I know but everything counts ! Also the fitting for the air spike is quite small so maybe a funnel shaped housing around it would help to guide the fitting onto the spike ? Once again only a microsecond gain but it all ads up .

[@perkinsengineering]

Yep all that was done through the 2000's, they shortened the stroke to the minimum height to get wheels off ground, then for rear tyres only only lift the rear of car. Big funnels became the rage too, this car is before that period.

[@timcave192]

Awesome work Jack👍🏻 Silly question, but what makes the jacks go back up and stay up during racing??

[@daz2372]

Spring returns

[@perkinsengineering]

Good question, if I had one on the bench I’d be able to show you, they have big springs inside

[@RBFR01]

Air jacks on road cars would be really useful.

[@Daniel-S1]

Where would the air come from?

[@perkinsengineering]

Probably wouldn't have a massive use for them to be fair, maintenance on road cars is a lot less, especially when tyres do 30,000-80,000 kms!

[@fnm404]

Stupid question Jack,but is the red container behind the drivers seat in the 93 car for water? If it is,love the simplicity.

[@perkinsengineering]

Drink bottle 👍👍

[@The_Evil_Monkey_93]

How stable is the car whilst it's on the double stands? I saw footage of a Supercar being worked on recently, after a crash and it was rocking around a bit on the double stands. Might be slightly unnerving underneatrh it.

[@perkinsengineering]

Very stable on these ones!

[@tomnewham1269]

Hi Jack. Do you know which year the air jacks were first used? I remember seeing a clip on KZbin of a pit stop of the 1984 HDT car that your father and Peter Brock drove which didn't use air jacks but from my memory by 1987 they were using air jacks. I also recall a race which Dick Johnson's car had a fault with an air jack which partially dropped down. Always good to see your videos and may I suggest for a future topic is the water bottles that are used in each of the different cars.

[@perkinsengineering]

It’s another good question, well before my time to be fair. I’ll have to ask a few of the old boys. Our first car, PE001, built in 1986 was fitted with them. Funnily enough water/drink bottles is on my list for future episodes!

[@timjohnun4297]

@@perkinsengineering I could be wrong but I'm pretty sure it was at the start of group A?

[@Daniel-S1]

Thanks + always horrified to see UK teams not using a stand with air jacks.

[@perkinsengineering]

Yeah not safe!

i have em on my 03 GT2 mustang car 😁they ain’t cheap!

[@perkinsengineering]

Depends on the brand?

[@rodneyjeffery9726]

Cool thanks

[@perkinsengineering]

You're welcome, cheers

[@reflexgb4264]

One question i have is i always see the v8 teams using the under the wheel type skates/dolly's why do you guy down under prefer them over airjack skates that you tend to see under gts?

[@perkinsengineering]

Go Jacks under the back axle, probably safer with the weight of our cars at nearly 1.5 tonnes

[@reflexgb4264]

@@perkinsengineering cheers for the reply was just something I always wondered about, for reference used them on btcc, gt4 cars that aren't much lighter no probs and sure make getting them back in the garage easy if a corner been plucked out. Ps love SC's best touring car championship in the world.

[@AdamWrightthegeek]

How much would something like this cost? Just the parts

[@perkinsengineering]

The air jack stands? I think they retail for around $2500-3000 plus GST

[@vech400]

Where do you get the rams from to fit to the car?

[@perkinsengineering]

We use Bilstein but other brands like AP Racing are available from local importers and distributors

[@vech400]

Thanks

[@vech400]

Is the reason you use AP or Bilstein because of regulations? Could you use a generic/industrial cylinder for a budget racer in a lower class if you wanted to try n fit something like that to your car?

[@vech400]

I guess you could even use nitrous if you were a drag racer to power them other than argon or nitrogen

[@perkinsengineering]

@@vech400 well when we built race cars they were never regulated. Bilstein were cost effective, easy to maintain and suited our application. They’ve only become regulated in the modern supercars as parts went to tender etc. I wouldn’t recommend using something that’s not designed for racing. These are designed and manufactured to not fall out on the track, not to blow up in the garage for example as high levels of air pressure can be very very dangerous, especially with fittings, hoses, lines etc.

[@volksdeutschewaffenss9670]

hey jack how about you interview your old man about the story of him blowing away the cops on the hwy and racing back to HDT, parking the car and hiding out in HDT, the cops turned up and description was of your old man, large mustache and glasses would make a great story interview , was it really your dad, i worked at AMI in Bertie st port melb at the time and we always watched in our lunch breaks the HTD guys test fanging the cars around the block testing the road cars, great days

[@perkinsengineering]

But he had photos with my baby sister being born at the same time and wasn't sporting a mustache! So was it really him?

[@volksdeutschewaffenss9670]

@@perkinsengineering enough time has passed under the bridge, let your old man tell the story, its history and makes a great yarn, hit your old man up, what car he was driving, what highest speed he got up too, and where he hid at HDT bertie street lying low, and how the chase began , baby sisters birth was a good excuse as was a quick shave, come on jack, queeze your old man, video will go viral, come on, what a great story

[@brdllc]

This is so bad ass, I second for this for sure. Of course this is all allegedly, LP would just be telling an “urban legend” 😉 wish I could’ve watched them road test the cars on my lunch break! Hahaha.

[@ldnwholesale8552]

Does the block of wood come with a Perkins part number?? Various heights? Though airjacks,, just another cost that is really not required. Build a decent jacking point into the car and simply jack it up, one each side. Then if you want to work on it use stands. I have welded some 'stand' points into the floor and simply drop stands through the floor with holes. Works well and cost about $50 for the materila to do it. And,, get rid of those dumb dangerous centrelock wheels, go back to 5 stud, Larrys preferred method!! And save a LOT of money

[@perkinsengineering]

Yeah air jacks aren't overly expensive, our cars always had them and the rules allowed it.
