- The bold on top system was superior to the arm system because the adapter gives virtual no additional resistance to the intake system.

- The arm system provided the advantage of bringing the mixer in a position along site the carburettor.

 By using the arm you can install the Tornado mixer in an engine bay were there is virtual no space or height.

The only disadvantage of the standard arm was the reduced air flow on powerful engines.

The reduced air flow wasn't effecting engines up to 275 bhp.
But the more powerful engines, 325 bhp and higher, lost in some cases too much power.
For this reason Iwema Enterprise designed a totally new High Performance arm for the Tornado 450 mixer.

We were able to design the High Performance arm in such a way that it can be used as a substitute for the standard arm on all engines.

The biggest differences are:

- The air flow of the High Performance arm for the Tornado has increased with 33.3% compared with our standard arm.
- More adjustable to the actual space between the top of the carb/throttle body and the engine cover.

These 2 advantages together will give your engine the maximal possible power output.
