Supercharging Question 1

[m899nyc]

Hi, yes, I have a very specific question regarding automotive engineering. I understand that my background is in electrical engineering - I'm not sure if I'm permitted to post in htis area - but I cannot seem to find the answer to this question anywhere.

Is it possible to supercharge any engine, as in build a custom manifold and mounting for any engine? If so, where can I find the basic instructions on how to custom mount a supercharger to an engine that does not have a "kit" available from an aftermarket company?

Thank you.

1. Yes.
2. Really old issues of HOT ROD magazine.

Mike,

Thank you for replying. Do you have any idea what time period in Hot Rod I should look for? The engine in question is actually a very old make engine. Thanks!

Your specific question is to unspecific to answer properly, but here goes some real guesswork.

If the blower is to be mounted on the intake manifold, make a sheet metal inlet manifold from material thick enough to withstand the load of the blower drive.

Make the manifold so the axis of a blower mounted to it is parallel to the crankshaft axis.

Buy or manufacture or adapt a blower drive to mount a pully on. When designing or adapting the drive and the manifold seriously consider how you will get the pulley to line up with a pulley you will mount to the crank snout.

Design, buy, make or adapt a hub that will mount to the crank snout in a fashion that is secure enough to reliably drive carry the load to drive the blower and other ancillaries as required. This might or might not also accommodate a torsional vibration damper.

In order to align the blower drive belt, you may need to relocate other ancilaries.

If the strength of the snout of the crank is doubtful, you may need to design and build a crank snout support.

You left out the low compression pistons and the new fuel system.

"Very old" may mean something different to me than it does to you.

Why not save us some time and aggravation and tell us exactly what engine you wish to supercharge.

Yes, sorry about that Mike.

The engine is an inline eight cylinder from a 1951 Packard.

 

[MikeHalloran]

They may not be easy to find, but McCulloch supercharger kits were produced for, or are easily adaptable to, that engine.

heh. look at the very recent issues of Hot Rod Magazine.
A guy up in UT did a roadster with supercharged Packard straight eight, blowing through carbs.

And a much more refined McCulloch is available here -

thousand of bucks new, both of which may not suit the spirit of your project.
In some ways a turbo might be easier to mount, involving more exhaust and intake plumbing than bracketry to get a supercharger's belt in good alignment.

I think a nice low boost system (3-5 psi) would pep up that engine and not require a lot of mods. There are a few books by HP, SA Design and Motorbooks

Does it have the auto trans with a REAL direct drive top gear? I wonder what that will think of extra torque or a turbo power band.

 

[JayMaechtlen]

If a guy's looking for performance from the Packard, a good place to start would be a modern trans instead of the Ultramatic. Two speeds with lockup converter? Ugh.
(I had one in a '51)
I guess one of the three-speeds with overdrive could be ok, thought.
cheers

Everyone else could stop wild guessing if you just stop playing 20 questions and just tell us what car it is in, what you use it for, what you expect from it, does it have any modifications etc etc etc.
