Ok guys I just wanted to know what fuel reg I should get, the one I've got at the moment is a standerd one. Don't know what bar I should be running either, I've got 83lbs Siemens injectors so need a good reg to suit.

Tell me if I need a 3 bar 3.5 bar or 4 bar????

Thanks

 

standard one is good for over 500bhp!

 

So standard 3 bar

 

No idea what bar it is but i still have a standard reg on mine with 500bhp but saying that i am going to change it so i can aero quip every thing

 

It's easy. If you want to run 3 bar, buy a 3 bar. If you want to run 3.5 bar, buy a 3.5 bar....I hope you see a pattern emerging.

Or seeing as you are spending money and they are all adjustable anyway. You can just adjust it to whatever fuel pressure you want !

Although isnt the OEM one adjustable anyway ? The old 2wd certainly was.

 

Depends how much boost you are running, at 0 bar boost a std cossie regulator is set to run 3.5 bar fuel pressure, and rises at a rate of 1:1, so 1 bar boost will be 4.5 bar fuel pressure, 2 bar boost will be 5.5 bar etc.

 

Ok I'll just get the standerd one as I was looking on the MSD site and they had all different ones

 

There's nothing wrong with the standard unit unless you want to run some aeroquip
