Psifer Build Thread - Kong 2650 & HHP/BES 426

[Psifer]

I've been receiving some questions about my build, so I've decided to consolidate all the information in one place for others to reference. There are a lot of minor details that I left out to try and keep the post as short as possible. Feel free to reach out and ask any questions.

Performance:

• HHP/BES 426 boHEMIth Long Block
  • Thitek Heads
  • HHP Racing Custom SR(Street/Rumbler) Camshaft
  • Billet Main Caps
  • Callies Magnum Series 8CWT Stroker Crankshaft
• Sipple Max Effort 8HP95
  • Billet Input Shaft
  • 2600 Stall Torque Converter
  • Billet Converter Mounting Pads
  • ATI Hemi Flexplate
  • Mishimoto Transmission Thermal Bypass Valve Kit
• Kong 2650 Supercharger
  • Kong 130mm Throttle Body
  • Nick Williams Upgraded Hellcat Bypass Valve
  • ARP Stud Kit ARP-400-8025 in conjunction with FI 0.5" Hellcat Blower Spacers
  • FI Thermal Blanket
  • AAD Adjustable Idler
• Injector Dynamics 1750cc Injectors
• JMS Fuel Pump Booster
  • Temporary until Fuel Injection Depot releases their triple-pump returnless style fuel kit for the TRX.
• Satera SENSORED Flex Fuel Harness
  • Requires some custom modifications, mainly extending wires and tapping into your AAT sensor, to get it to work with the TRX. It is supposedly plug-and-play for the Challenger and Chargers.
  • The only way for sensored-flex tuning without needing to go to an aftermarket ECU.
• Kooks 2" Long Tube Headers with Green Cats
  • I sent the headers off to Swaintech for their proprietary "White Lightning" ceramic/aluminum coating.
  • Paired with the Borla Atak catback and Borla exhaust tips. I no longer experience the infamous exhaust "chirp" with this setup.
• FI Stage 2 Interchiller
  • Pierburg CWA400 Intercooler Pump
  • FI 3-Gallon Reservoir
  • FI Normally Open Solenoid
• Tuned by Zdung Ho!

Brakes:

• RB Performance Brakes 18" Caliper kit with lightweight, two-piece rotors.
  • They eliminated my biggest frustration with the factory brakes, where they would heat soak very quickly and start to fade. I have yet to experience brake fade with the RB kit.

Exterior:

• ADD Baja Bomber Front Bumper
  • Paired with 3x Yellow Baja Design LP6s and 2x Baja Design Squadron Pro Yellow SAEs for the fog lights.
• ADD Baja Bomber Rear Bumper
  • Paired with 2x Baja Design Squadron Pro Wide Cornering Yellow lights.
• Line-X
  • Covers bumpers, fender flares, side steps, and rocker panels for a two-tone look.

The new setup is broken in now. I still have a lot of tuning to go, but so far I'm cleared for WOT pulls on 93. I will continue to update this thread as I go on my journey of trying to see how deep into the 9s this setup with take me. I expect the Kong 2650 to be the limiting factor at this point.

We need a WOT pull video!

We need a WOT pull video!

That will be coming very soon! I was just doing some data logging today to confirm the WOT pulls are looking good. It's so much quicker now; I run out of real estate fast.

Awesome build. Please keep us updated as you progress.

Holy cannoli, she sounds like Satan himself singing a lullaby!

Here's a small 3rd(35mph)-4th(110mph) gear pull. Pump 93 @ 15psi of boost. The shift point is set at 6800rpm, which will eventually be raised. This is the slowest the truck will be. It looks a lot slower on video than it feels in person. I will definitely get better quality video once I'm done with the tuning process. I'll be working on adding more ethanol tomorrow. Afterwards, I will be going with the smallest pulley to make 22+ psi on E85. The Kong has a boost ramp between a PD and a centrifugal supercharger. Butt dyno says it has less low to midrange torque compared to the IHIs and Whipples.
