it seems to me that ANY type of product designed to cause the airflow to be more turbulent would work on a carb or TBI, but would be completely useless on a TPI, since there's no fuel in the air stream until just before the intake valve.

so, just what's the turbulence supposed to mix, air & air??? more turbulence without any other benefit seems like it's reduce overall airflow, and therefore reduce power.

Why not just buy a Tornado, its cheaper.

LoL, has anyone here used that Tornado thing?

are you serious?

that thing is like putting a fist in your airbox and expecting MORE air to flow higher cfm

now that gave me a good laugh when i seen that infomercial!

Got my tornado as a package deal with some ***** enlargement pills. Now my car is slower and I can't get it up.

I got a used one off of Ebay for $15 to use as a spot to mount my N2O nozzle. That's about the only use I could see for something like this...

:yourock:
Yeah I bought one of those tornado things a long time ago for a carb app, now it hangs on the wall as a reminder for stupid gimmic's, A friend of mine recommended this for my truck (TBI) cause it worked great on his, I just ran across the one for the TPI set up and thought WTF??
