did i say mph,i meant to say mpg.
brain fart again,i forgot to take my fiber again.

 

Hey Guys DONT WASTE YOUR MONEY ON THE TORNADO!!!!! It's BS One of the Companys that maks something very simler Coned my company into testing these on our work vehicles and over a 1 year test period we saw absolutly no improvement!!! Its snake oil!!! Save your money for real mods!!!

 

I agree with mgithens for the most part. That is practical advice,

I'll just add an old rule of thumb: Generally speaking, for the best fuel economy in most gasoline engines you want to shift at a point close to the RPM where your peak torque is reached. So with the 1NZ-FE in your xB that is 105lbft @ 4200 rpm. For optimum fuel mileage, you'll want to shift at about (or a little above) that RPM between gears. Beleive it or not, taking off from a stop light and running up to 4k RPM in each gear until you quickly get up to speed will use less fuel than taking off super slowly and shiftting very early. It's more efficient.

Start at a stoplight, rev to a hair past 4k rpm in each gear and get into 5th as soon as you're up to speed. Cruise at 40-50 mph in 5th gear and coast to the stoplights. That's the ticket.

The flip side of that rule is for maximum acceleration, in that case you want to shift at a point close to your peak hp (6000 rpm) or a bit past that so you end up close to 6000 rpm in the next gear and stay close to your peak hp.

Torque is what moves the car off the line, where the peak hp is, is just an indication of where the car most effciently aligns its mechanical advantage (gearing) and torque output.

 

Just about anything you do to improve airflow will improve MPG a little, you just have to be careful that you don't love the sound so much that you keep revving it up at redlights and driving like a bat out of hell :twisted:

 

hey i can get you some stickers to go with that, they add atleast 20hp to the wheels. haha

 

people tend to go back and forth about the effect of lightweight wheels on milage... however, in my personal experience, my milage has gone up between 1.0-1.5 mpg since switching a few months back...

also the additional mpg gained from adding fuel additives might be a bit misleading... you are, in essence, adding more fuel to your car... and since we have a fairly small tank, it can throw off actual #'s a bit...

hope this helps... and keep us posted with what you find...

 

Today I put a Tornado to my xB intake, just to try it out. Just impression.. very slightly different :? . Same idling rpm. A little better trottle respond, a little bit more torque, I guess. I will try to get an MPG number after the next fill up, some times this week.

 

Tape all the seams on your car.
Fold your mirrors in.
Remove your windshield wipers.
LRR Tires.
Accelerate quickly and short shift.

 

I know that with larger vehicles (ie Rec Vehicles) that if you add water injection (petrol pressurised intake manifold only) that there is a substantial increase in milage per gallon.

 

Lol people who think the tornado work are dumb tornado is full of shyt u get no better mpg from it. Its all in the mind

 

Swifty, I don't know if the tornado works to save gas. But the first impression is that it doesn't look safe to put it in the intake. After I put it on and drive for about 10 mins, it seems to move a bit down the intake pipe. It cannot hold securely in the intake.

So I remove it and return it to the store, before I even try to see the mileage on it. IMO, it is not worth buying it. It may cause more harm than its benefit anyway.

Hope this helps ;)

 

In an engine designed to take advantage of the higher octane it does make a difference. My VW GTI 1.8t says to use 91 octane, I didn't listen and I was getting the worst mpgs. Then the engine didn't seem to like to stay on in idle. I changed to 91 and the mpgs went up 2 mpg and the engine gave me no probs.
Now with the scions they have not been designed to take advantage of the higher octane, so you would just be wasting your money.

 

I put using gas treatment on the xB. It does make a different of about 1-2 MPG, if I put only 8oz per tank. But when I put 16oz of treatment, the mileage went down by 1-2 MPG also. The car has better acceleration in both case.

The gas treatment works to some degree.
