The more modern the car the more complicated it seems - although the basic principle is the same, electronics play a bigger role in both engine management and diagnostics. Motor mechanics are becoming electricians and fault finding is just a question of plugging in a computer! 

Nevertheless the combustion process is still primarily a mechanical function and the only way to create turbulence in the inlet gasses is with a mechanical device like the CB-26P. 

This new Peugeot 406 2.0 Turbo has quite a complex engine - the vacuum servo, for instance, is drawn off a branch of the manifold and is not suitable. There are however two vacuum lines off the manifold intake/throttle body. One is a crankcase breather which is restricted and also not suitable but the other, on the right of the intake, is ideal. The tests on this car showed conclusively that there was better economy - never less than 10%; more response and better pulling power especially noticeable in second gear and lower emissions even though the car has a cat. Generally our experience on more sophisticated cars such as this, is that response and low end grunt is improved and petrol savings vary between 8 - 12%. With modern engines it is obviously less easy to make dramatic improvements in petrol consumption but 10% is not to be sneezed at especially if it comes with a performance premium.

Similar difficulties are encountered with the 1.8 Peugeot 306 the servo hose connects with just one branch of the two branch manifold and the PCV (positive crankcase ventilator or, more commonly called, the crankcase breather) can't be used because it's restricted at the throttle body end - solution: there is a blanked over vent precisely at he centre of the manifold in the perfect position.

Simply remove the rubber blanking plug get some 12mm hose and attach a 5cm piece to the vent with a jubilee clip then attach the Ecotek to this and use the rubber blanking plug to cover the exposed end of the Ecotek device with another jubilee clip - voila!

Bill's Peugeot (left) was much more responsive and on his annual trip to Devon a fill up that normally cost £30 was only £25 this time (same prices!) so he's saved about 15% on his fuel bill - oops sorry for the pun!

As for slightly older cars; this Peugeot 309 performs better than new according to its owner who is an engineer from Surrey. He said:

"As soon as I pulled away after fitting I knew the device had made a big difference - the engine was much more responsive and acceleration was smoother - this was a big bonus given that I am now getting nearly 20% fuel savings. This is the best car accessory I have ever bought!"

The 205 and 309 GTi Peugeots all suffer from lumpy low end and what is called 'Kangarooing' - ie: jerky acceleration from low revs. The CB-26p goes a very long way to curing this as both Revs Magazine and Motoscope discovered (see the What you say page).

On the subject of older cars we mustn't forget good old British engineering. We have had a fine tradition of excellence in motor engineering in this country - people laugh at some of the cars we built but any problems with the British motor industry have all been down to bad management, lack of investment and politics. Just look at Formula 1 - the World Premier motorsport showcase - virtually all the cars and engines are made or assembled in the UK - the Ferrari design team are virtually all Brits and even the Mercedes engines are assembled in the UK.

Here's a fine example of a well made, reliable and much under-rated car the Rover Montego, perhaps not the prettiest or best appointed car in the World but a solid workhorse still running good as new - actually better now with a CB-26P fitted!

Better response, smoother acceleration and 15 - 20% improvement in fuel economy. Five minutes to fit - QED!
