Cossie convert,

If I am not 100% sure about a technical statement I make, I will qualify it with something like "I believe". John made a statement with no such qualification, and it was wrong. This kind of dissinformation cannot help in any way, it can only cause problems.

Heard a lot of talk recently about the merits of fitting one of these to a normally aspirated engine (Sport) - I think TSL do them. However, nobody has been able to explain how it works and what it does exactly as opposed to a OE fuel pressure regulator. Any ideas greatly appreciated.

This type of regulator allows the fuel pressure in the rail to rise with engine rpm. The std. item maintains a relatively constant pressure. They can cure pressure related problems such as flat spots. The FSE item helped with a modified Mondeo (Turbo`d) I had but If you have`nt actually got a problem don`t bother.

Thanks John - I don't think I'll bother as they aren't particularly cheap with fitting!

 

John D is incorrect or just plain wrong.

FPRs regulate the fuel pressure in relation to the manifold pressure. Linear FPR's increase fuel pressure at a the same rate as the manifold pressure, rising rate FPRs increases fuel pressure in faster, non-linear fashion.

You are correct, however to be fair to John D, the FSE sales blurb presents a graph showing fuel presure rising at an increased rate plotted against RPM.

hmm would this cure my flat spot on my turbo???

That will be why you edited your post then after a re read

My sincere apologies for making my reply too simplistic.
