Evening all.
If you have seen my project thread, you would of seen my car was mapped last month and didn't get too good a result. Only 189bhp ATW. Main reasons was lack of boost (caused by a serious boost leak, was only making 3psi) and failing fuel pump not supplying enough fuel. Ive now fitted a Walbro 255 so fuel pressure is not an issue and boost leak has been dealt with however Steve at track and road suggested at the time fitting a rate of rise fuel pressure regulator before it goes back for re mapping along with the pump and sorting the boost leak. I never asked why i would need one but now wondering, how would it benefit me? Do i really need one or is it just worth going back with the new pump and boost leak fixed?

Cheers

440cc injectors, After about 210-220bhp which should be well within reach on my setup. Once the leak is sealed and new pulley on, should be seeing 7-8psi

Something like that do the job?

Based on that information then, I agree with the others.

A 4 BAR FPR will be just the ticket, you won't need any more than that, plus I've never rated those 'rising' ones anyway.
