Replace original X1 Series regulator internals with the conversion kit of your choice (Part #'s 13013, 13014, and 13015) and you have a regulator with vastly different characteristics. While versatility is one of the X1's greatest assets, it is far from the only new design feature. Utilizing larger (3) -8AN ORB inlet/outlet/return ports to accommodate increased flow, at the same time Aeromotive reduced overall size and the weight by 33% (compared to Aeromotive 13109 regulator). The new X1 design eliminates the compromise common to other convertible regulator designs, with the optimization of all internal components including the diaphragm/poppet, spring and bypass seat, the X1 delivers all of the performance and features you expect from an application specific bypass regulator, regardless of what you decide to do with you r induction system tomorrow. Above and beyond the expected performance, you still have the amenities like a 1/8 NPT gauge port and 1:1 ratio boost reference port for forced induction applications. Base fuel pressure adjustable from 35-75 PSI. Vacuum/boost reference capability. 1:1 rising rate for forced induction engines. Gasoline, ethanol, and alcohol compatible. (2) ORB-08 inlet/outlet ports on the sides. (1) ORB-08 return port on the bottom. (1) 1/8 NPT Gauge port with plug. 1/16 NPT Boost port with 5/32 hose barb. 0.188 bypass with matching spring and poppet. Handles up to 150 GPH with AN-08 return line. Suitable for any Aeromotive pump up to A1000. Mounting bracket included.

Why Drivers Choose FAST of West Chester

  • I can't recommend this place enough. Being able to trust a shop in the performance world is big. The 2hr drive to get there, is worth knowing the job will be done right. Very happy to have found this shop, to
    support my builds going forward.


    Donald Wojnar
  • I recently had the pleasure of working with FAST of West Chester for some performance upgrades on my 2022 WRX, and the experience was nothing short of exceptional. I opted for a Borla S-Type exhaust and Cygnus Coilovers, and the team at FAST nailed the installation, fitment, and setup to a T.


    Adam Cranston
  • The team at FAST are excellence in every way. First, I consulted with Dave on mods for my HPDE track car. He listened and advised me on the best parts & mods to achieve my goals. He was patient & gave me space to research the options presented & worked with me through several changes before we built. Second, the build execution was flawless, proper heat shielding, bracing and poly everywhere. All components worked as advertised.


    Bryce Budd
  • This place has been my go to shop for all things Subaru. From simple service to performance parts and tuning, they have been top notch.


    William Brunell
  • Excellent shop. They installed a Cobb Stage 2 DP and Whiteline Sway bars and end links on my 2013 WRX. The work was done right and clean. The estimate was accurate. They were very knowledgeable, friendly and gave me the straight scoop on exactly what I was getting for the money
    and what I needed to get where I want to be with it. I'd recommend them
    to any car enthusiast.
