spiral max
ok the new guy has to ask a stupid question
i just read about these in sport compact ad section
wanna know if anyone has heard anything good/bad about them
theyre called spiral max. they install into your intake and are supposed to increase velocity.
considering getting them if they are worth anything
lemme know if ya know anything

actually, Spiral max is just a bent peiece of metal. It sits inside your intake tract after the MAF sensor.

Just think about the dynamics of it for a moment.
The "spiraled air" must go through the 90 degree bend into the Throttle body area. Let's just give them the benefit of the doubt and say it can manage that.
Then it gets cut in half by the throttle body butterfly. Let's give them the benefit of the doubt and say it splits off into 2 perfect sub spirals as it passes the throttle body and enters the intake manifold plenum chamber.
Then those 2 perfect sub spirals magically combine back into one spiral on the other side of the throttle body in the plenum chamber?
Then it is supposed to split up into 4 smaller sub spirals to head down each inake runner?
Those 4 smaller sub spirals then stay perfect through a 180 degree curve of intake manifold runner?
They then get blasted by 44 PSI fuel injection...
then they squeeze through a .044" opening to enter one of your two intake valves (or split the spirals AGAIN to enter EACH intake valve).
Then they keep spiraling around inside the combustion chamber till the pistion squishes them and the spark plug ignites the air fuel mixture.
Do you really think a cheap $0.99 piece of bent tin can accomplish all that? If so, why has no major auto manufacturer copied the design or bought the rights to these devices? Why do you not see them used in drag racing, NASCAR, and INDY cars?
Why? because they don't work.
