Before
you pay big bucks for this gimmick,
take a look at our tests.
We used a 1987 Z-28 Camaro with a 5.0 Lt Port
Fuel injected engine. It had an automatic transmission which
we kept in drive for all tests except the IM-240 tests, where
we put it in overdrive.
Each of the tests below were run three times.
Otherwise, the car stock was run through the 3500 rpm stall
test three times and the average horsepower generated was
167. The numbers below are an average of all three tests.
S= Stock air intake
F= Funnel type air intake adapter
T= Tornado type air intake adapter

You can see that the funnel gizmo
restricts the air, causing a rich condition that makes this
car go a tad faster, but at a huge raise in CO which translates
to a reduction in fuel economy, contaminated oil and carbon
build up in the combustion chamber.
When we asked the Tornado folks
about our test results, they said we needed to install it
and let the car get used to it. We should not have tested
the car so soon. Go figure.

Dear Mark:
I'm the service manager at (an auto repair shop) in MO and
have experienced the "Tornado." The originator came
by our shop 4 or 5 times before we let him talk us into trying
it on our co. truck. It's a 1997 S10 4.3l engine. We
documented mileage, 1/4 mile times etc. After a month
or so, he stopped by to see what we thought of it. Our
mileage went down and we saw no difference in the performance.
He tried to tell us that we needed to use it in conjunction
with a K-N free flow filter to get the best results. Imagine
that!
We took the tornado
off and put on the K-N filter and guess what? We got
better performance. Maybe he should throw his Tornado
away and go to work for K-N!...........
Love your show and
have all my techs and managers listening as well.
Greg
