View Full Version : Question for people using forced induction

02-18-2002, 10:22 PM
I have some fuelling problems at higher rpm's with my SC
So I used a fuel pressure regulator from a 325e motor (2.5 bar) then I put a socket around it and tapped it done (higher pressure) this solved my lean fuel mixture at higher rpm's but killed my idle. Sounds like a big 427 v8.

I am currently shopping for rising rate fuel pressure regulators (fmu's)
anybody hear good things about the cartech system? I know they basically invented the rising rate fuel pressure regulator 25 years ago just wondering if they are as good as advertised.

Thanks in advance
