OMG GAINED 15 HP THROTTLE BoDY SPACER
They were good for the older engines when the fuel was sprayed before the throttle body and air mixed with the fuel, but now its sprayed after the throttle body so this does nothing but make a cool wanna be turbo whistle!
thanks to a friend on gmfs, where i got the picture.
You might even lose power using those tornado things since your slowing the airflow down.
i would recommend you save your money for a cold air intake or some long tube headers or full built exhaust.

OMG Gained 15 HP THROTTLEBODY SPACER
I talked to the owner of Vararam last year and he said the spacer are good for a little more torque because of the extra intake volume and not beccause of the swirl design. Also very little hp if any on some engines. He makes them for the LS car motors with no swirl designs. I took my Airaid off my truck and cut off and smoothed of the swirl part and reinstalled. It seemed to help a little with throttle response.

i noticed a 2mpg change on gas mileage, and it also gave me a little bit of torque and throttle response on my truck, plus the whistle does sound kinda cool when you get close to red line

I'm no physicist but it just makes sense to me that there is no way a spiral groove on the outside of an orifice that takes in air is going to create a spiral effect on all the air entering into it. It's more likely that the tornado things would do this, but at the risk of decreased cfm. The only thing I see these spiral cut grooves would do is create more turbulence, which would also decrease air flow to a degree. Though not even remotely as much as the tornado would.
It's just my opinion but these are about as effective as fuel line magnets.Patrick

the basic theory is the more air you can get in the more power it will make you have to think of your motor as a over glorified air pump if you raise your intake volume then you will gain a few just like superchargine or turbo's they force more air in then what naturally flow in

I thought the TBS simply increase the volume of air....which is something most engineers of an auto maker dont foucus on.
I purchased a TBS a day before this post. I may set the truck back to stock settings as right now I have a performance tune programmed. See what she drives like then.
However, I will say I did notice a difference in the ol girl after I installed it. Nothing earth shattering...

I bought a BBK 85mm throttle body for my last truck, and that turned into a nightmare. The part itself cost $300, but then it took me almost 3 days trying to get the A/F ratio under control. Even then I ended up with a ton of black soot in my exhaust, I ended up taking it off after 3 months because of several other problems it caused. If you do buy one make sure to get it professionally adjusted, because you will be all over the place with that thing and I wasn't ready to jump into a tune then and I still am not ready. I thought about giving the TBS a shot just for fun, Summit Racing has there brand for $50 so I must try it out???2004 Chevy Colorado
