power boost valves

[mdjones]

are they worth it?

 

[Adams_16v]

they are if u have other engine mods so you can tweak the fuelling. cams etc.

They dont give any real benefit.

Just control the fuel pressure. Benefit comes from the larger diaphram which responds to load changes better.

If setup correctly and used in the right circumstances then they are good, but the clio isnt one of those good reasons.
