Does thhe tornado rally make a difference??

[ChevyWade]

does the tornado really give better gas mileage. if so how much?
thanks

[calgary_redneck]

I saw a test one of the car magazines did on it they even ran the car on the dyno and the end result was that the fuel economy was unchanged and the hp was slightly less with the tornado installed. Which makes sence when you think about it as the theory behind the whole thing is flawed anyone who says that it makes a difference has their heads in the clouds

cool, i didnt really think it made sense either, how the hell could spinning air move faster than air moving in a strait line? Im thinkiong about getting a k and n filter for my truck, does it make much difference as far as throttle response?

and i was thinking about removing the pipe that draws hot air of the engine into the intake and sealing up the hole on the intake. is this ok, and do i just leave the other end open?
thanks for any help

Check in the earlier posts i believe it is about TB's or EGR's. but if you referring to the EGR assembly there was a whole thread with "more knowledge" about this mod. Check it out.

i would invest in a tb spacer (i have a helix tb spacer) seems to help out some with the tourque.

i remember when i didn't have bills. now im 19 and my paychecks got bigger, along with my wants and my bills. now im working towards getting another bill. a 4-wheeler. time to put my truck on hold. no more spending money on mod for it.

You guys wanna talk about bills!?! Wait till you're 25 with a wife and a 5-month-old boy at home, two cars, house, student loan, credit cards, utilities, and all on a 40k/yr income. then you can cry about not having any money for the toys you want!

[digitalhorizons]

You guys do know that if you are driving a Silverado you already have a tornado built in to the air cleaner intake tube!! Dont waste ur money to buy another one!!

[ChevyWade]

are u sure, mines an 89. but i dont know crap about cars. i was lookin at my intake more closely today and i noticed a butterfly valve that is held closed by a spring. it is connected to a duct that runs down and draws heat off of the exhaust, and i cant figure out why the hell they would put that on there. any ideas?

its a heatriser for those cold mornings........it diverts warm air off the exhaustmanifold to your breather untill the motor warms up

i dont even want to know how many bills i am going to have at 25. thats exactly why i want to buy my toys now when i am still young (19) that way they are all payed off by the time i turn 25. well all will be except my student loans.
