Supoercharger in a brumby?

If I had a brumby I'd certainly do it. Absolutely.

But I have a new Jumbuck and havent a need for a brumby. Pity. Just that after my latest ride on the supercharged Tweety trike I would make hell or high water to put the same set up in a brumby if I had one. Think of the benefits.

- retain the same or even less compression ratio. So a slightly worn engine would still be ok.
- No need for twin carbs, twin carb manifold, linkages (and obtaining them)
- no carbie balancing issues
- No EJ conversions and the issues that come with them (body, loom, space, complexity- mind you there are many positives)
- Not much more fuel usage
- No cam or internal changes if boost is mediocre
- Cost effecitve. (debatable but considering the alternatives of modifying the ea81 in the traditional sense.
- cool factor
- Sc can be operated in reverse
- and add a cool badge. lol





Cost around $1500 max. Power- incredible at 6-8psi, torque neck snapping throughout the rev range, simple, no electronics and one extra ribbed belt.

Ok, you guys are saying...what about the loaction issue. where is it going to go? Firstly where there's a will there's a way...my stategy since converting Tweety to Subie power last year not to mention the roof creation.

What about a shaft mounted above the left head to the rear of the engine and the SC12 or Sc14 mounted central above the flywheel area and utilise the spare wheel area for the carbie. Remember the carbie doesnt have to be moutned directly to the SC. It can be remote with a tube connecting it. We are talking draw through. Furthermore the Sc can be run in either direction so it could be reversed if you want the carbie to extend across the drivers side. It can also be laid down reducing its height. Actually I'm amazed at the virsatility of the idea. Find space for it and a way of powering it and you have your 30% extra power.

And a small bonnet scoop isnt out of the quesiton. Anyone wanting to pioneer the concept has Joels thread and now my tweety thread as a good guide. Just need Subie Brumby die hards out there to work through the space issue.

Your thoughts?

I posted this in your other thread


I dont know what type of SC this is, but it worked and it fit under the bonnet

I hope someone on here does do it to a Brumby, would be very cool

Would there be any legality issues though?

Silverbullet. My understanding is that it is an accessory meaning is bolt on peformance like ehaders or extra carbs. Hence also no engineering certificate. But we should all check with the arseho...sorry Vicroads or your state RTA

Gannon, for soem reason I didnt recognise that engine as aSubie engine. I dont recognise the supercharger.

Looks neat enough. and like the manifold under the blower to the intakes.

It may be different between ute and sedan as well with approval flexibility, commercial V passenger car. Change emmissions you need some testing and certifying in NSW. Our EJ conversion experts are gonna say EJ will / can come under 1500 bucks
If anyone did SC an EA81 in a four speed, may well need a VW auto !

I'm pretty sure that SC is a 1950 vinatge of a air cooled VW beatle. Pretty rare find nowadays

And some! (speaking for SA only)

Briefly, any form of forced induction, if it was not the OME fitted in the AUDM, is a no go.

Example:

EA81T in a MY or MV = no as they were not bought out here

EA82T in a L-Series Wagon = ok as we had the RX

I (as do you SB!) 'know a guy' who mucked around with all sorts of SC in Brumbies and a 4 door Leone...

And, unless someone has got software to turn a digital pic into like looking at a slide the wrong way around - that yellow one is a LHD, with the pully on the SC looking a bit like any other pulley , which was all I could see on a supercharged beetle on display a few years back. Now, I think I know what a complete VW SC looks like - another curiosity resolved But another started - where is the alternator ??

Yeah that is a Gen1 Leone coupe from that was used for rally in the US.

Good spotting on the alternator, i suppose it was removed to save weight, maybe a fully charged battery would last a race?

They may have used a magneto to bypass needing an alternator and a coil as well ... just a thought

I would love to put a supercharger on my brumby but I'm pretty sure I would need to win lotto

I cant wait to finish the little things left to do with my instal and get that dyno tune, because it has transformed the machine.

In the two rides I had around the block the low and mid range power was amazing.

Toonga, I'd be looking out for a SC12 or SC14 while they are still at reasonable prices $250-450 and sitting on it till you can afford to buy the carbie etc.

Mine came form a guy that bought it to put on a V6 Holden but of course it was too small, like the SC14 would have been. And some want to upgrade form the 12 to the 14 so SC12's are out there.

They weight 11 kgms so you can cost the postage.

this ones on ebay but it is a toyota sc14

but it could work with an EJ22 pity I don't have a cent to my name

TOONGA

That a good deal.

One day toonga. baby steps. life gets better.

*sigh* why must I see a thread like this before I even have my brumby registered?

I'd love to do this but have to get it registered and on the road before I even think of spending money on "performance"

$1500 for that is awesome.

I'll keep you in mind once I finally get the car on the road

And AShr that cost estimate is with everything.

But bare in mind. If you are registering a car for the first time eg from scratch and it already has modifications that require an engineering certificate- I'd instal the SC first and get it all done. I've been in touch with my engineer and he suggested he'd prefer to engineer that final product rather then sticking the sC on after he's done.

Costs for my project were:

$500 sC12 (yes overpaid for it but wanted it there and then. Cheaper available)
$320 Fully refurbished Dellorto 40 DHLA carb ebay
$60 Spare carb for parts
$110 Twin carb manifold datsun 1600-2 litre Lynx (to halve for one carbie)
$300 Blow off valve (cheaper ones for under $100)
$40 Ribbed belt size 5pr-0965 common size
$50 ribbed pulley for crank 135mm, ea Ford tensioner pully unit
$250 Engineer to fix solid clutch pully and fit ribbed pulley to crank pulley, lathe a steel mount for BOV to custom manifold
$30 Hose form BOV to air filter box
$24 Middys for a air filter box amde from a wire box
$30 Boost gauge

$1694. Under $1500 if you make savings on some items.

yeah, don't think I need Engineers cirt as it's only got a 2" body lift and no other mods

sounds awesome though, I'll add this to my "list of things after rego"
