Spiral Max (fwd)

[Orin Eman <orin@wolfenet.com>]

>From the diy_efi list.  Yes, the Spiral Max thing is a scam, but note
the comment on the Nology wires as well...  Stay well away from
the Nology stuff - at best they capacitively _drain_ spark energy
to ground.  At worst, the ground connection is bad and they
cause cross firing.

> the only change is the addition of the spiral max device?
> It has been proven on carbureted and TBI fuel injected enjines that
> turbulence induced *after* the fuel is introduced to the intake charge that
> more complete atomization/vaporization takes place and there is a benefit
> to be had, but on PFI or Diesel apps, turbulence in the airstream *before*
> the fuel is injected can have anywhere from no effect to a detrimental effect.
> on PFI, the fuel is injected onto the backside of the intake valve usually
> within an inch or so of the intake valve.  A turbulent airstream will have
> negligible effect on this atomization process.  The swirl that is created
> by the design of the combustion chamber and the placement of the intake
> valve will be the definitive factor.
> On a diesel engine, the swirl can inhibit the flow of air if it is too
> turbulent.  It will have 0 effect on combustion, as combustion in a diesel
> occurs  *during* the injection of fuel and at the top of the compression
> stroke.  Any swirl imparted to the airstream is long gone by the time the
> piston reaches the top of the compression stroke, the injector opens and
> combustion begins.
> This really sounds like a modern day "snake oil" scam.

> Wonder if these are the same people that came up with the "Nology Plug wires".
> They cost me $1500.00 in repairs to my neon, then told the CA State atty
