cyclone2 or surbo ????????

this two product is useless

Maybe you should consider on this statement..

When Does Hiclone Not Work?
Why does the same part work on one car and not work on another same model car? The reason is normally related to Air/Fuel ratio or engine tune. Hiclone increase's airflow at all times by up to 21%. The only time Hiclone can’t work is when there is a mechanical, electrical or fuel system problem. This means the engine is un-able to match the air/fuel ratio to the increase in airflow generated by the Hiclone product. If you add a lot of products to a car to increase airflow through the inlet or exhaust, at some point you will need to add more fuel to match (eg: in the UK if you fit a sports air filter to SU carbs you need to use richer needles). But this can be fixed. This is also why the first Hiclone usually saves more fuel than the second; it has access to the most un-burnt fuel.
The rule is that any engine is only as efficient as the amount of fuel it can completely burn per combustion stroke and convert into power (torque), the more air per combustion stroke, with the correct air/fuel ratio, the bigger the bang and the right foot spends less time on the pedal.

Electronic Fuel Injected Engines (Petrol & Diesel)
By using sensors like Air Flow Meters on the inlet and O2 sensor on the exhaust, the engine's ECU will match the air/fuel ratio and create a new fuel map. The ECU will need time to re-learn (about a week) this is why dyno shops who test products by doing one run without, and one run with any product don't know how to use a dyno on an EFI car (as proven in the “Street Commodore” magazine test on our “More Power” page). You will use less fuel to achieve and maintained the same speed. A second Hiclone will give a further increase in airflow.

any add-in gadget is still perform within the capacity of the engine itself,the best is still do a transplant to get a more obvious and long term power solution.

To get the max power through surbo depends on the air flow sensor, If I'm not mistaken it will not have any effect since the air fow sensor is right infront after the filter, and the surbo is fix at the throttle, because of that, the air flow sensor will tell your ECU to distribute the amount of fuel. Hence Putting a surbo will not make any difference unless it is fix right before the sensor such that the sensor will sense a higher air flow and distribute higher fuel which will result higher power.

For cars that the air flow sensor is fix after or in the throttle body, this design will give higher effects for surbo but limited, you won't be able to feel any dif....
