Has any one tried that thing called turbonator? I think is the same that some people sell in ebay as Tornado. It claim a win up to 35 HP. Does it worth the money?

It will add as much horse power as the GTR badge on the side of that car in the pic...

wow! 400hp increase?!

Yea it won't do anything. Turbonator is a bunch of crap. A friend and I were talking about this. In theory it could work to add more power, but the problem is, it's running off the intake, so it spins the fan at the speed you take air in. So it's essentially not pushing in any more air than what's already coming in. If anything, it might make your car hesitate more from a stop. Because now you've got this stupid fan impeding the airflow in your intake, so it has to spin up. I love the fancy name for a fan. Vortex Generator. I also don't understand when Higher Horsepower and Better Gas mileage became directly proportional.

In theory it is supposed to create turbulance in the intake. So your air being sucked through the manifold is spinning. This in turn creates a more even fuel mixture because the fuel sprayed in is mixed up in this spinning air. That somehow creates more torque. More torque, and light driving will create more gas milage.

I can see how this theory would work well on a carborated engine where you really could use some better fuel mixture. But fuel injection? I think its pretty close to ideal already. I have never known anyone to add this to their vehicle.

35hp increase is probably on a carbbed 400ci V8 or something. On a 2.8L engine... it can add up to (but maybe not any at all) 4hp???

In the ol days of carburetors got some defenders, using the same theory, is a nono for FI.

If you think about it.. How well do you think the air and fuel on a Z FI motor gets mixed??? It has like 1.5in. before it hits the valve

Bleach

but the injectors actually spray the fuel in a mist. Carbs let loose fuel through a needle and rely on the velocity of the air to dispurse and 'mist' the fuel through the intak runners.

I know its released in a mist but it just seems strange to me.. BUT obviously it works

I think the word you guys are looking for here is "Atomization". In theory, by creating a vortex, the spinning air atomizes the fuel being sprayed more effeciently. It's all good on papaer, But like Bleach said, The system is already pretty efficient on it's own. It may do a little better of a job and add a slight increase in power, but we are talking about a very small increase at best and probably one that isn't even noticeable.

lww

Damn! Rod beat me to it again...

'Atomization'... um, big words are fun!

One of the reasons the last 1" of my intake runner in the head was left alone when it was ported/polished. The sand casting marks actually help create turbulence in the airflow better 'atomizing' the fuel.

As has been mentioned, this is a carbureted motor so it's even more important to get the air moving around to evenly 'atomize' the air/fuel charge.

You can actually get a much better performance improvement from your motor by having your injectors rebuilt, flow tested and then flow synchronized.

Getting the flow to be the same across all injectors and making sure the spray patterns are optimized will do wonders for your FI motor, in huge noticeable ways.
