Ok, I am going to be doing the Eaton M112 install on my 95 LT1 engine. I'm also using the OE cobra 39lb injectors with adapter plugs. My question is what kind of fuel pressure regulator would be best to use with a roots style blower to add adequate fuel pressure vs. boost? Thank you for any info/help.

 

Found an Aeromotive for lt1 with 1 to 1 reference, will this be all I need? Are there any better than this or is this the most I should need? Thanks.

 

I don't think you want a 1:1 ratio.... that's what the stock fuel pressure regulator is. If you are going to try and control the A/F ratio using fuel pressure, you need a fuel management unit (FMU), that has a specific ratio of fuel pressure increase to boost, like 7:1 (for example). But if you are doing a blower, the best way to handle the extra fuel for boost is to use a 2-bar MAP sensor and the appropriate "tune". Let the PCM control the fuel. There's a thread in the "Computer....." forum on 2-bar tuning.

Can we assume that you are not using a stock style LT1 fuel pressure regulator, since you will not be using the LT1 intake? If so, that leaves you a large degree of freedom in selecting a fuel pressure regulator. But you need to investigate the best way to control the system.

Probably the best idea would have been to post this on the "Forced Induction" forum. Do you owant me to move it?

 

Sure, maybe someone there has heard about something like this. I havent started on it yet, just trying to do my research first so I can collect everything needed. Thanks.
