I need a rising rate fuel pressure reg for a project i'm working on at the mo.

Anyone know where i can get one from?

Thanks,

Doug.

Try this place Doug,have dealt with them quite a bit....

These reg`s are the daddy too..

 

Cheers Diva. Looks good, but not rising rate unfortunatly

 

 

It says the pressure will rise... not that its rising rate.

1:1 is a normal reg that raises or lowers fuel pressure on a 1:1 ratio with plenum pressure.

I need something like a 1:1.2 ratio.. a rising rate.

 

Diva, he means that as boost increases, ie the differential between boost and fuel pressure as well, so it is more at a bar than it is at idle etc, ie it rises rather than is just maintained

 

Correcto mundo!

Prob is i can't find any for sale apart from one in the states for $260.

 

NEVER use these on a turbo car with EFI unless its completely remapped !!

Highly UNRECOMENDED IMO

 

Im sure Doug knows what he is doing

 

I am sure he does, my remark was for those who arent as able

 

Fair enough, although given that someone as clued up as the diva didnt even know what a rising rate reg was, I doubt many people on here will be intending to fit one as they all wont know what one is either, lol

 

There is no need for them usually but this is a special situation.

Its not actually for a car. Its for the bike shown at the bottom of the page in the thread below.

The injectors will be too small and all i have to change the fuelling is a Powercomander 3 which gives basic control of an aplpha-n map and not alot more.

I can't replace the injectors for bigger or turn the fuel pressure up as it will bugger up alot of other parimiters like warm up and accel enrich that i cannot re map.

So the plan is to use the best comprimise which is a rising rate FPR that will only increase the flow of the injectors up top when on boost and therefore shouldn't effect the other parimeters so much.

All a bit bodgy and not the way i would do it, but my mate only has a small budget and therefore i have to find the solution to fit the cost!

 

Sorry mate,totally read your question wrong

Just automatically assumed you needed a rising rate with boost to keep the fuel pressure matched......

 

No probs mate. It's sometimes confusing as people often refer to a FPR that will compensate for positive pressure as rising rate when in fact it isn't.
