Lol Probably true....I got one on my old 1.2 8v and believe it or not it did make a difference....not just in my mind either. I doubt you would notice anything on a bigger engine but for example slowing down for a mini roundabout near me would need a drop to 2nd to pull away with a bit of pace but after it was done (and set up for what it is worth) I noticed that 3rd would do fine
Surely you would have to have the engine mapped to benefit from the pointless increase in fuel pressure.
The engine will only take as much as it needs in I thought...

made a difference on older engines but not really worth it with a newer engine. Gave a decent increase on the vauxhall C20XE/LET lumps and a friends valver.
Do you know the increase it made on the valver engine? One was fitted to a F7P I bought... Was considering ripping it out.

No RR figures but pulled much harder than before it was fitted. pulled away from all other valvers at the time.
IIRC didn't the mess about with the fuel pressure of the 16v cup cars???
Sounds interesting. thanks for that.

all it is is a pressure regulator. all it does it force more fuel in when you turn the fuel pressure up. It can't give a power increase just by doing that
