UPDATE: the car has undergone significantly more modications over the course of this whole build. There are more updates throughout the rest of thread.
Hello all, first post fun post. I have the pleasure of owning a 2017 challenger Hellcat. This car is loads of fun and Is absolutely beautiful to look at from every angle. But I am definitely not one to leave things stock for long. After owning it for about 4 months now is she has already undergone many modifications.
Started off with a upper and lower pulley swap and mid pipe pump gas tune. Made 780 to the tire. Had fun but wanted more power.
Went with upgraded driveshaft, differential brace, 3.09 gears, Triple pump fuel system, e85, heat exchanger thermostat etc. made 825 to the tire spinning on the dyno. Very fast car!
Motor went kaboom racing a local charger Hellcat shortly after. Sad day.
Now! The car is getting a beefier set of internals and a pretty whipple 4.5 on top of it.
Sooooo... here is the mod list.
New 6.2 block
Stock crank
Mahnley rods
Diamond pistons
Thitek Heads
Stock cam
Whipple 4.5
Fore triple pump fuel system
ID1300
Catch can
Stainless works complete exhaust headers to tips.
10% lower pulley
Torque converter
Aluminum drive shaft
3.09 gears
Diff brace
Bwoody control arms upper and lower.
All poly bushings for rear
Mopar lowering springs
Vossen GNS-1 wheels (hand brushed, with dark smoke transparent clear coat) 20x10.5 rear 20x9.5 front.
Nitto 315mm rears
E85 pillar gauge
Car will be a daily driver. Goal is 1100 street daily. No excuses. Nitrous is sitting in the garage wondering if it wants to be installed.
I would have done billet crank but I don’t want to wait 16 weeks. We will be running a tune with the 4.5” pulley which should be 20psi. The 4.25” pulley is probably what’s gonna be needed to break 1100 Hp. 23-24 psi should get that whipple to whine.
Looking to have a stealth tank in the trunk to carry an additional 20 gallons of fuel for extending E85 range. I want 350+ mile range min.
I’m used to whipple cars as I own a 2004 terminator with a built 5.3 and 2.9 whipple making 730 to the tire. Also a fun daily driver. The challenger will take over the heavy driving while the cobra becomes my weekend baby.
I’ll start adding pics of what parts have come in so far. Mario at gear head fabrications is doing the installation work.
What’s nice as this has been ongoing so the build will be done hopefully within next couple weeks.
UPDATE:
Dyno result and pics/videos on page 10 of this thread. Enjoy.
