I seen this thing in my sport compact magazine and was wondering if it really works. They said it was dino tested and everything. Has anyone used this product? Is it worth the price? Thanks.

did u read the article about the "performance" of it? on the dyno it showed absolutely no gains in performance. This was posted also somewhere around here, im sure u can find it.

From that webpage:

I was pretty amazed when i 1st flowtested the
Tornado by itself on just the flowfixture
the amount of swirl torque was amazing !!!
it maxed-out my Swirl-Meter at only 2.000 inches of
H2O test pressure !

However when the entire induction system path was
flowtested with the Tornado as a "UNIT"
the extreme swirl-effect of the Tornado vanished,
completely unmeasurable on my flowbench !!
I increased flow test pressure to as much as
36.0 inches water..still no increase in any measureable
swirl induced by the TORNADO ...very disappointing !

i then had the idea to flowtest the Tornado just
on the carb by itself....i thought surely i would
see very large swirl readings with the Tornado .
Again, very disappointing, the swirl increases
were barely measureable , bouncing between
0.000 inch/ounces -to- 0.20 inch/ounces of swirl-torque
even if test pressure was increased all the way to
6.000 inches of water !

the carb bores, venturis, throttle-plates/butterflys
overwhelmingly canceled out Tornado's swirl !
even with carb butterfly all the way opened,
no changes in Tornado swirl effects.

if the carb itself is just about totally
"negating" the Tornado's swirl effects,
i can easily see why when the entire induction
path was tested , no recordable Tornado swirl effects
were seen .



Granted... this is for a carb. engine... I beileve the results still apply!!!

junk.... been talked about a lot on speedoptions.. and many have said junk.

some said on a total stock enginge it might help some..
but a modded engine no..

why put something in the path that might get sucked into the manifold??

Think maybe we need one more new folder, Hare brained $hit we have seen before that is worthless!!!!!

I wouldn't trust any type of forced induction that only cost 69.99 :)
