  • Question

    Will a stock mechanical fuel pump work? What electric pump is recommended?

    By Clyde H. on March 25, 2018

    Answer
    Cylde, The stock mechanical fuel pump on your engine will not supply the injectors with the required fuel pressure. we recommend the 12-920 fuel pump for inline solutions. We also have in-tank fuel pumps for various applications. You could also check out the 550-850K Master Kit, it comes with a fuel system.

  • Question

    I know the super sniper 2300 will support boost but I''m wondering if the standard sniper 2300 would also work for a turbocharged application. I have read on forums it is as simple as downloading the super sniper software but would like to know from you guys and girls. Main reason is I''m making an intake to fit one of these and my motor is around 60hp right now(vw bug) so the standard sniper 2300 sounds like it would be more than enough for this little engine:) Thanks again Nate Btw I am already a proud owner of 2 of your sniper kits great r+d they are awesome!

    By Nate B. on September 21, 2019

    Answer
    Yes, they have the same 2.5bar map sensor. But they only have 2 injectors, so your horsepower is going to be very limited. Additionally, there are no additional inputs or outputs for boost control, or fuel pressure/oil pressure monitoring.
