but has anyone tried, heard of, know is crap, whatever....one of theses systems:

since turboing is hard and cant really be useful due to high compression ratios maybe these would be good?!?!?
again, just an idea...
Please dont laugh...

nar don't laugh.
I was chatting about these kinda of system at work the other day. We were debating if u had a fan pushing air into your CAI would it help? at idle it would have to help for a better launch were concluded depending on the CFM rating of the fan. while the car is moving...we didn't decide as the airflow is high if u take it direct from the grille anyway although some airflow tests would proivde this...
in my mind - and this is in theory only - a fan forced system is a bit like the big fan used on dynos...it might help with your launch it seems to me. I would like to see a high quality fan that could push a sh*t load of air in - heheh hey wait a minute thats a turbo?

These have been discussed quite a bit on public forums but just to take a few lines from their faq:-
5. Doesn’t the impellor fan block the intake and restrict the air flow?
No it doesn’t. The Force Flow 4.0 inlet flow area is 95mm wide, so with that size inlet minus the area that is blocked by the motor, the inlet area is actually larger than that of your standard 3.0 inch (76mm) intake pipe. So even if you installed the unit and never switched it on, you would have a far more effective intake system than your stock setup. Having this inlet area big enough was one of our biggest design features, as it is the flaw of some other Electric Supercharger units available on the market today.
Makes no sense, size is only a part of the picture, air flow is also very important since the air is now restricted by this device and has to find a way around the fan.
6. Why is it recommended that it only switches on at full throttle, can I run it all the time? Basically, unless you have your foot flat on floor and the throttle is wide open, no amount of air you pump in will get through. Think of it like a flood gate, if the gate is only half open and you try and pump 5 times more water through the gate, the entrance to the gate will just flood with water. In the case of the throttle taking in air, the same thing will happen, the air will just flood at the entrance of the throttle body and all the way back through the intake pipe. Not until you open the throttles gate all the way open can the air flow freely into the manifold. Knowing that the Electric Intake Supercharger is only going to be on at what (wide open throttle) for 10 or maybe 15 seconds at a time, we have designed our motor to get maximum power for its size for that amount of time only. So using the Electric Intake Supercharger when it is not needed will only decrease the lifespan of the unit and give you no gains.
Agin mean that unless you are at full throttle, you basically will feel the effects similar to turbo lag, so unless you drive with your foot constantly flat your car would probably in general feel slower.
10. How much will the power increase on my car?
The gain in performance gains differ from car to car depending on vehicle make, engine size, intake type and many other factors. Gains from small engines of about 1.5 litre have been seen higher than 10% but we like to safely say around 7%. On larger engines around 4.0 litres displacement, we suggest average gains will be around 4-5%.
Hmmm....most manufacturers will round up. So I would assume that at best one could expect an increase of about 5% on the FTO which equals about 10hp while the device is obviously on at peak RPM. Thats about the same amount of bhp you could get from a decent filter and CAI.
So to review...this would give you the effects of a 10hp bottle of NOS but with a constant restriction and slower build up. For just 10 or 15 seconds of fun at one time you're better off getting a decent NOS kit that has no restriction and can give you a good 50bhp more+ So to some it up.....WASTE OF TIME

I heard of this kinda things...
And they have been a debate where many people said they have tested it and it actually works, and also increase the mileage (better combustion). However, some car expert said that these things only causes reduction in air flow. Many of us have been trying to do some tricks in the air piping so that there's less "90 degree" turns and the air intake can suck in more air with less restiction. And this device actually do the other way round. Although it has a larger diameter, but there're many fans there so the air is... well, u know...
However, I have not tried it, and i am not a car expert... so... hope there're some experts commenting on this ya

By the time you get enough wattage from your alternator to run a fan big enough to shift enough air to notice, you have sucked all the power away just to run the alternator!
You want a positive pressure manifold without a turbo or a supercharger?
Get a big bottle of pressurised air and a regulator set at 6psi, run it into a sealed manifold system and hey presto, no lag, no power drained from the engine and, as your depressurising the canister, freezing cold air to boot
Piece of pi55 really.

that much compressed air and you'd run your air fuel ratio too lean and bye bye engine...Storm wrote:Get a big bottle of pressurised air and a regulator set at 6psi, run it into a sealed manifold system and hey presto, no lag, no power drained from the engine and, as your depressurising the canister, freezing cold air to boot
thats the same principle as nitrous, N2O... at high tempretures it breaks apart into nitrogen and oxygen, the nitrogren cools and the oxygen is used to burn

True, you would need an uprated FPR, and preferably some sort on stand alone fuel management system but its still cheaper than a turbo providing 6psi because you'd need all that anyway with a turbo.jonowong wrote:that much compressed air and you'd run your air fuel ratio too lean and bye bye engine...Storm wrote:Get a big bottle of pressurised air and a regulator set at 6psi, run it into a sealed manifold system and hey presto, no lag, no power drained from the engine and, as your depressurising the canister, freezing cold air to boot

Oh, the downside is that when your air runs out, so does your driving
But I'm sure you could find a valve or a flap to get you around this.

up to a point your standard ECU can compensate with fluctuations in air pressure and oxygen levels but when you ask it to do too much it is fooked.
When adding nitrous most kits will have an extra injector which can be fitted to the intake and provides the eatra fuel you need.
And of course, for a turbo you need an uprated fuel management system anyway.
However I have found a flaw in my plans. At normal air pressure and 8000RPM the FTO will displace 8000 litres of air per minute.
Thats 8000 revs per minute times 1/2 for firing every second revolution times 2 litres of air every time it sucks it in.
Thats a bloody big air bottle
Back to the drawing board I think
