Small Scale Performance Mods...

[FamilyWagon]

Hi,

 

I'm looking to enhance the performance of my newly purchased 2003 Galaxy 2.3 Ghia FamilyWagon.

 

Does anyone know if these really work Ecotek Power Boost Valve . Has anyone got any experiences of using them or does anyone have any suggestions as to what I can do for a bit more power?

 

Cheers,

I'm always sceptical about these things, consider the following:-

1) It can only admit air into the manifold when the manifold pressure is less than the air pressure outside. They state it works on high performance cars such as Imprezza's and Evo's, theyre turbo'd and therefore have pressure in the manifold.

2) It supposed to make the air 'swirl' how can this be when it apparently can be connected to any pip attached to the manifold.

3) Assuming a normally aspirated petrol engine, there will be a vacuum in the inlet manifold so this unit will leak air in there. What happens to the mixture? it goes lean, what does the O2 sensor do? tells the ECU it's lean, what does the ECU do? Ramp up the fuelling where are we? Back to square 1

 

The very best economy measure you can do is drive around as if you don't have brakes. Every time you use the brake pedal you may as well chuck a cup full of fuel out of the window. I have never seen lab condition tests that prove these work, maybe that tells you something.

I wouldn't go for the EcoTek either.

Depending on your budget I'd go for a chipped ECU first, then a Decat pipe & maybe some head work (high lift cams & porting, although these may sacrifice some of the smoothness of the engine).

 

I cheated with my Vectra though and fitted Nitrous injection. It gives the performance of a Turbocharger without the cost, although gas doesn't last forever at
