4kq supercharger?

[Ken Keith]

Supposedly there are some advantages in having a centrifugal 
design, instead of a roots type, positive displacement setup like 
the Eaton.  Then again, they do use them on the high end stuff.

There are advantages regarding mounting considerations.  With a 
centrifugal design like Vortech, Paxton, or Powerdyne, you only 
have to mount piping to the round inlets and outlets.  The unit is 
supported by separate bracketry.

I think the Eaton setup generally requires a custom intake manifold 
to support the supercharger.  Correct me if I'm wrong.

A bunch of Saturn guys have been waiting for an individual that has 
been working on a s/c kit for them.  He's going to be using 
Powerdyne for the s/c.  http://www.powerdyne.com  The Saturn 
supercharger project webpage is located at

The 8.5:1 compression ratio and stout bottom end of my 4ksq has 
gotten me thinking that it would be pretty easy to "slap" onto it.  At 
least easier than in my 9.5:1 Saturn motor (with 150k).

I've picked up on a few tidbits of info regarding s/c'ing n/a motors.  I 
think it comes down to proper fueling under boost and retarding 
timing before knocking, as well as having a healthy and strong 
bottom end.  There are fuel pressure regulators that are available 
that increase pressure under boost or other factors.  However, I 
don't know if or how these products would work with our CIS 
systems.  The J&S Safeguard could apparently be used to keep 
the timing under control.

I have a friend that can machine some things, and I can do some 
mig welding.  Time is another story.  I'd at least be interested in 
following along, if not participating in a development effort.

Then I can supercharge the 4ksq, and keep the 5kcstq intact, 
hopped up in its own right.
