Con me out of supercharging my 1916
A friend of mine who did the bodywork on my Oval is upgrading the supercharger his V6 Calais just to be different.
+ 1 - He says he can get an Eaton supercharger for about $1800. He recons we'd get a cross-ram manifold from a Torana and run 2 side draft 45mm
carbs. He can TIG-weld aluminium and has offered to do as much welding as I want to get manifolds and brackets working.
+2 He suggests mocking it up on another car first and I just happen to have a '54 waiting for a resto and a spare complete 1600.
+3 The plan is to run a conservative 5 or 6 psi boost on my 100 RWHP 1916 as it is or maybe add some spacers or a head gasket to reduce the 9.6:1
compression ratio a bit.
+4 The ports on my head are small enough to adapt to the factory DP manifold end castings. From there we may adapt some aftermarket single carb
manifold to the blower.
-1 At this stage I worry that there wouldn't be enough room for dual pulleys for the fan and supercharger in the tight oval engine bay.
In the cold light of day this is probably a stupid thing to do to what is a pretty reliable combination. Please help con me out of it.

Hi CT
Not a bad idea. Twin Webber's? Better of with EFI as it will control fuel and spark much better to help the motor live. Turbo charging is a much
better solution but requires a bit more commitment.

definately go to EFI as it will give you heaps more room to play with. Injector bosses welded into the twin port manifolds right down near the ports
then mount the blower where the dizzy would sit.That way you can run one belt with a tensioner type set up. Run individual coil packs and a sensor set
up on the crank pulley and your in business. Grab a throttle body from the wreckers off a late model Honda and if your mate can do all the welding and
fabrication then that's a big step in the right direction.
The only problem I can see is the room. Might need to massage the boot lid a little.....

I say go for it!
For starters keep it a simple draw through system with carb and maybe water injection, this setup alone may be enough to surprise and thrill you.

Nope, I won't be talking you out of it dude. You should check out the yahoo club for supercharged VW's. From memory its just called "blownbugs"
searching should bring it up pretty easily.
The side drafts sound like they would look awesome, though I would go with webber style throttle bodies to get the looks and still be able to run EFI.

You guys are no help. You're supposed to talk me out of it!
To me old-school webers (Or is that ye-old webers Cam?) are as important as the VW badge. I understand the superior performance and economy of fool
injection but I love brass jets. The closest thing to a computer that will ever be bolted in to my car is the MSD 6AL.
Some enthusiasts like to re-engineer as many components as possible because modifying stuff is fun. But I want to keep things pretty simple.
Can I get a flatter dizzy cap that sends the leads out horizontally rather than vertically?
Do all these supercharges need long snouts to mount the pulley on or can that be shortened?
Thanks for the tips. Keep them coming.

I don't see any reason why the snout length can't be modified - provided you don't stuff up the balance of the rotating mass. The Detroit blowers
on my boat have no snout at all - and are gear driven.

Commondores only have the snout so that the pulley line up with the rest of the engine pulleys due to Holden's placement of the blower on the V6. Yes
it can be changed. Not 100% sure but you may be able to even buy shorter ones but I could be wrong. (doesn't happen very often lol)

A 0.060" head gasket will drop the CR to 8.2:1 which would be safe for considerable boost. I love my EFI and computer engine management, but am
inclined to agree with Gracey in that keeping it simple for your first attempt. Then once you get a feel for it, go hard core on it!
I had a thought about using a toyota blower as a draw through EFI blower on Reub's 1916. If I were to do it i'd replace first remove the distributor
and run a twin coil waste spark crank triggered ignition. This would allow the blower to be mounted a lot lower to the block. Then the output of the
blower would go through a charge cooler that would be mounted on the parcel shelf. This would mean making 3" holes through the fan shoud to run 2"
pressure piping through(allowing for engine movement etc, or convert to porsche cooling). Run a small radiator mounted on the front beam and thats
more or less it.
7lb would be safe on a 8.2:1 CR 1916, and would make around 150-160hp easily. At 7lb and above id be wanting water injection or charge cooling, and
engine management capable of retarding the igniton based on boost. With charge cooling 14lb not a problem, and expect over 200rwhp. Thats provided
your engine revs to around 7ish. Considering the CR im assuming it does.
Have you noticed that nobody is talking you out of this ! Seems we are all a bunch of petrol heads

I know ther is plenty of debate about the benefits of centrifugal vs roots superchargers. The centrifugal is smaller so might fit better between the
fan housing and crank pulley.

Try and find a centrifugal thats even close to being small enough to run on a vw engine. They are generally all for V8's. The smallest are for
engines around the 4lt mark, so some 6's. I guess it has something to do with the load of the gear up systems that drive the turbines.

Those are Autorotor screw type superchargers.
Nice units made in Sweden.
I had two of the 3150 units on my engine running at 53% faster than engine speed.
They are a bit pricey,
although if they are sold based on the US dollar
they may be cheaper than what I payed some 10 years ago.

Pictures!
I'd love to see pictures of somebody else's effort.
My first shots are likely to be uninspiring. Think rusty '54 oval, a grotty 1600 and bits of cardboard with duct tape!
Nobody has been able to convince me not to do it yet! But it would be difficult to get it up and running for under $4000 all up. But you could see
some IDAs and porsche Fuchs on ebay when I get serious.
Re: The eaton that eats and shits from the top I might just have to
see that after work one day.

I stumbled across DUB74L aka Joel's post on the super charger he fitted to his engine. I wish I could find a link to it because its much better than
this post. Nice work Joel.
I doubt I'll be playing with a super charger for a while. I've got an engine rebuild and the Portland Drags, BugIn and a Dutton Rally to prepare
for.
The cogs will be turning in the back of my mind though; or are they gilmer drive pulleys?
