Carb'd nitrous fuel set ups (advise needed please)

[Black_65]

Hi All,

Im in need of some direction on fuelling set up on VW's on NITROUS running carb motors. 1st I'd like to say sorry for posting this topic on 'cal look lounge' but wanted to get an over picture on what to do.

Ok so I have a 2165cc and looking to run a 50hp short of nitrous for strip use (car still road legal, we'll until next year) and when I designed/built my set up I planned on using a Facet fuel pump on an 8mm line to a regulator with x2 outlets.

So the 1st outlet goes to my 2nd fuel regulator set at 2.5psi as my 48 dellortos don't like higher psi over wise they flood from the top. And the 2nd outlet goes to a lock off valve with a gauge set at 7psi for the nitrous jet choice. So the reason I'm asking for so detection is that I went to set the fuel using my jets and the regulator is not adjusting!.
So looked into the issue more thinking it was the regulator but  I think my fuel pump is not man enough for the job or I've got the whole thing wrong.

I've been advised by Bernie (stitch up) and Danny (lil lizzy) to look at running a 2nd fuel pump and regulator for the nitrous set up and wire it up with the micro switch to work the fuel when needed.  But this would need a second line to work...

So what I'm trying to get at or find out if it could be done with the set up I have but with a better fuel pump to run at a higher psi then use the fuel regulators to dial in 8 for the nitrous fuel and 2.5 for the carbs. Or could I T-piece into the main line at the back of the car with a 'lock off vale' and run the 2nd fuel pump and regulator that way?

Thank you all for your help and input but will be interesting what will work as not everyone has efi and nitrous .

I run a Pro Fogger system. Completely separate fuel system for the nitrous. 2 fuel pumps (1) motor (1) Nitrous. 2 separate -6 fuel lines. I have a safety switch for the nitrous system on the fuel line side. If there isn't at least 4 PSI of fuel for the nitrous system then the solenoids will not activate. Holley red pumps for both. Running a .020 nitrous and a .022 fuel jet , adds [ Attachment: You are not allowed to view attachments ] about 120 HP

Team97 ,  Very clean engine, everything is all business and no BS. I really like the idea of using a Hobbs type switch , in your experiance have you ever had any switch failures and which brand have you been running ? I too am going to be running Nitrous on my street/ strip car also . Mike McCarthy
