    I will be going through the build of our Hellcat here!
    We are stoked to get the car and begin the mods!

    The following details our first round of mods. I'll comment on them as time passes.

    Mickey Thompson 275/40R20 ET Street Drag Radials - These are excellent for general cruising on a stock Hellcat. I highly recommend them. Good in the rain up to 80MPH. They do not like standing water at 70-80 and will hydroplane. If you see standing water, slow to 60MPH or lower. On a modified Hellcat, they are still much better than street tires but will spin obviously. These were our daily driver tires before mods. Love'em.
    Mickey Thompson P305/45R17 ET Street R's - We are now daily driving these tires and wheels, and they hook much better than the 20's. Once you drive a while and they get hot, they hook pretty well on the street. They do NOT like rain. Period. Drive slow, as they have no water channels.
    Weld 17x10" S77 RTS - What's not to like? Beautiful wheels.


    Metco 2.85" Upper Blower Pully
    ATI +10% Damper + pinned crank
    Gates K100572HD Blower Belt
    Unlocked PCM, Diablo inTune i2 and custom tune.
    Speedlogix Catch Can
    160deg Thermostat
    ID1000 Injectors
    Kenne Bell Boosta-Pump
    JBA Offroad Mids
    DSS Aluminum Driveshaft
    NGK 6510 Plugs
    BWoody 2" add-on Heat Exchanger
    www.Billet-Customs.com Decal Kits.

    Interesting Notes:

    Trouble Codes encountered during mods: (corrected with updated tune).

    PCM-P00EA:
    ISO/SAE Reserved - Apparently a transmission code not liking the additional torque. This only shows up at the track. Normal street driving doesn't throw this code.
    PCM-P0128: Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature) - Code with 160deg Thermostat

    Personal Observations:

    The Hellcat Charger is by far the most fun vehicle I have ever owned (before mods). I have owned a few interesting vehicles (no exotics) and think this statement means a lot. I suppose a Ferrari FX might be fun too but I'll never know.

    So for the common man, this thing is unbeatable!

    I know many of you say "Why mess with perfection?!" but I will tell you that this car (again) was the most fun I have ever had driving any on-road vehicle. And now, with this much power. . . Holy Cow! I am so glad I made the jump and modded this thing! It is freaking SICK!!! When I get into it, you can feel the raw, visceral, amount of power just clawing at the pavement. The acceleration is really incredible in 3rd and 4th gears.

    No looking back now!


    Here is a video of our Track rental at PBIR. Thanks to DRP's dad for putting this together.
    As luck would have it, the timers were set up for 1/8 mile and not even working on my first run. But I have posted the time slip from a run after this one.

    Update. Went to the track Friday and ran a new personal best of 10.25. Temps were 77 to 80 deg.
    No change to this setup. I honestly think I could squeak a 9.99 out of her with the current set-up and cooler temps.

    Second round of mods has been completed!

    We added a LMI Intake
    2.75" Blower Pulley
    2309 NGK Spark Plugs
    3.09 Center section and gears.
    New Dyno tune.

    And the results are. . . . BOOYA!

    847HP and 734lb/ft Torque on 93 octane!

    This puts us as having the highest documented pump gas Hellcat in the World for the time being! I will be getting to the track ASAP to see what kind of times we put down!

    Many thanks to Gearhead Fabrications in Stuart Fl. and owner Mario Abascal! Tuned by Brian P McMahan from Diablosport.

    Thanks guys. The Hellcat is a cheap car to modify to this level. Best bang for the buck I can think of. That's a big reason to get one if you want to go fast.
