My Atos is year 2007 auto model which has a straight flow inlet filter box as different from the 2005/2006 model. Surprisingly it has more pickup than my wife's 2005 model. Maybe the ECU is an improved one. I improved the performance further by adding/changing as follows:- a)2 MegaRazin voltage stabilser to the battery, another one in the cigarette lighter, b) changed to extractor type exhaust manifold,c) add an electric supercharger triggered by accerator cable at the inlet manifold area, d) add a hydrogen fuel gadget, e) thicker spark plug cables which were modified using other car cables bought from Brothers Shop, f) suck air con cold air into the vacuum tube.The car pulls away very quick and feel nice to drive. However, I didnt want to change the whole exhaust system and therefore top speed is not very much improved. I have retired and do not drive fast anymore. And also the tyres are standard 13 inch type.That Atos (M)speeding very fast is because they fix turbo and the engine will rosak very soon. I had seen one fixed with a turbo, but the owner return a week later for overhaul and the owner did not touch it anymore. There is also a Atos advertised in Mudah for sale on 13/11/2012 which is fixed with an Daihatsu engine 660 cc, but dont not know how fast it can run. What I like most is when I fixed the hydrogen fuel gadget, the exhaust is very clean, hardly any black soot, meaning the engine cylinders are also very clean inside.
However, with so much improvement, saving of petrol is not in my intention because with so small an engine how petrol it can drink? RM50 can get 300km for town use is good enough for me. Thanks. I will not delve on Atos anymore because I am now driving a Proton BLM 1.3 using NGV and it is more challenging. 5 sen per km only, RM 45 a month, how about it? Lagi jimat, lagi power.
