ADAM MONFORTES’ “SLEEPER” DODGE CHARGER DAYTONA
Adam Monfortes’ “Sleeper” Dodge Charger Daytona
By any stretch of the definition, Adam Monfortes’ Charger isn’t your prototypical “sleeper,” since the yellow and black 2017 Charger is far from subtle. The big fat tires and the aggressive engine rumble portend the fact that big power lays in wait. But today, the Charger, and its sister model, the Challenger, generally require the signature Hellcat logo on the fender flanks to really achieve performance superstardom. Daytona’s like Monfortes’, well, just can’t be that fast, right?
But that’s where the sleeper aspect of this amazing machine wakes up.
With the help of Adam Montague (yes, another Adam) out at Spankin’ Time Motorsports out in San Bernardino, Monfortes’ Charger Daytona has the specs that supersede the Hellcat numbers. Frankly, as his dyno sheet numbers will profess, this Charger’s list of pieces, noted below – generate 840 rwhp – that’s significantly more than the Hellcats 707 hp (at the crank) and more than the muchlauded Demon.
“Everyone is doing the Hellcat build up these days,” noted Monfortes. “But no one is doing the Daytonas. I wanted to do something that was different and between the extensive engine modifications and the exterior upgrades, my Charger is really something different — and beside, I’ve already done the Hellcat thing!”
Continues Monfortes, “The power output at this level can be difficult to harness. Case in point is the transmission that has been completely rebuilt and strengthened by Southern Hotrods. Between the big tires and the big power, if the tires don’t break traction, something had to give. In this case, it was the previous transmission.”
But the route to a super-fast car that can achieve sub-10-second e.t.’s while retaining streetability can also be paved with slippery spots. To deliver that versatility, Monfortes relied on Montague. Specialists in these kinds of builds, Montague understood just what Monfortes wanted and flowed in the right parts and pieces together to deliver the right combination. Featuring a number of Hellcat-tested parts and adding some race-bred pieces like Cp-carrillo pistons and Molinar H-bean Rods, the engine is more than up to the task.
840-RWHP 6.4L MOPAR ENGINE BUILDUP
With a goal of creating more power than even the Demon powerplant, Montague began the build of a completely fresh 6.4L engine goal using higher-end parts. Mike Lazano at Cp-carrillo Pistons created a set of blower pistons that would match the weight of the stock pistons, each piston/rings/wristpin set within 6 grams of each other.
Tom over at Molnar Technologies prepared a matching connecting rod, each unit with 2 grams of the factory piston and rod weight. Interestingly, the crankshaft and rotating assembly remained stock. Topping it off, BMS Racings’ James Cole ported and polished the heads and finished them off with a five-angle valve job.
“We picked the Edelbrock Supercharger as a test to see just what the twin-screw
supercharger could generate,” said Monfortes. “A lot of folks were using the Whipple supercharger systems, but I wanted to use something different from the norm. Currently, we run about 13 pounds of boost to achieve the 840-plus horsepower at the tire figure. With E85, the engine runs cooler, which allows for more boost and reduced chance of engine detonation. But fear not, more horsepower is on the way, each pound of boost equating to 22 additional rwhp, according to [Monfortes].”
Monfortes picking the Edelbrock supercharger is proving to be a super high-efficiency unit, exactly what he was looking for from his Daytona. For fuel delivery the Daytona sports a pair of twin 465-lph pumps and an FC3 harness to handle the E85 fuel in place of the factory 290-lph unit. This set up will support 850 rwhp, the limit for this system. Montague noted that higher horsepower figures would require the swap to a system with a return line (Hellcat and other high-performance Mopars don’t use return line fuel systems) and adjustable boost reference regulator.
Continues Monfortes, “In the future I’m looking to add ethanol injection that will allow for even more boost and horsepower along with an MSD Boost-a-pump to raise fuel pump output. In the high heat of Southern California summers, ethanol injection is critical to avoiding detonation.”
RESETTING THE BAR FOR MOPAR PERFORMANCE
As the name implies, Spankin’ Time Motor Sports in San Bernardino is fast becoming the place to go for Mopar enthusiasts looking to turn up the wick on their vehicles. Montague, as the owner, has laid down some impressive credentials over the last 15 years, including taking the best time for a Hellcat at the Muscle Cars at the Strip event last May of 9.33 seconds at over 150 mph. Currently, his high water market for Hellcat output is right at the 1,200-rwhp mark, meaning he’s making in excess of 1,400 hp at the crank. Vehicles that turn out that kind of horsepower have put his shop in high demand.
“We are an exclusive Mopar shop. With the exception of those customers who were with me before, we made that our policy,” says Montague. “That allows us to focus on Mopar brands and deliver the kind of performance our customers pay for. We are an engine builder/installer and dyno tuner, but we can address all aspects of the vehicle right down to a rollcage if necessary. The majority of our cars are daily driven yet run sub-10-second quarter-mile times, which makes installing rollcages mandatory to run at many dragstrips. For those applications, we use Carlin Fabrication in Calimesa, California.”
For a time, Mopars were the one left out of the mix, Chrysler holding tightly to the computer codes that allowed modification of the vehicle ECMS. While GM and Ford vehicles were easily upgraded through computer technology, the Mopar tuners stood on the sidelines unable to make these cars compatible with many of the standard performance upgrades demanded of enthusiasts. That all changed when Diablo Sport broke the code — and from that time on, Mopar fans have enjoyed unlimited performance enhancement.
“We use Diablo Sport CMR software and HP Tuners to calibrate our vehicles, and
I tune the cars for compatibility with the changes I package into every vehicle,” continues Montague. “We package every engine for the targeted performance on a case-bycase basis. We exclusively use Southern Hot Rod Transmissions, Pro-torque Performance Products for our stall converters, and Fore Innovations for fuel tasks. Whipple is still our first choice for force induction but the Edelbrock’s performance has been impressive. From mild to aggressive, we see our performance output abilities at Spankin’ Time Motorsports as unlimited.”
Continues Montague, “Even through we may be moving the Titanic [reference to
the heavyweight of the current Challengers and Chargers] we build cars that drive great, are very fast, and retain the comfort items we know our customers want from their cars.”
The Edelbrock 2650 supercharger used on Monfortes’ Charger is a firsttime experience for Montague, the two Adams wanting to try something different. The twin-screw supercharger system, also used by Whipple and Kenne Bell, are the standards for the industry. Edelbrock’s 2650 version of the Twin Screw system took Montague by surprise with its power output at low boost and impressive low air intake air temps.
“My shop focuses on forced-induction intake systems, and the Whipple superchargers have been the best so far in terms of power, intake air temps, overall kit quality, and fitment,” says Montague. “With Monfortes, we are hoping the Edelbrock 2650 will be a contender on the smaller displacement supercharger kits and offer a solid option to any customer wanting to run something other than a Whipple [supercharger]. With [Adam’s] car we are currently running 13 psi and spinning the supercharger 16,660 rpm. Edelbrock states that their superchargers will handle 18,000 rpm. If we put the next size supercharger pulley on the blower, it will hit between 15 and 16 psi and turn right at 18,200 rpm, which will put us on the cutting edge for the supercharger’s abilities and peak efficiency. But the horsepower at the tire will be over 900 — and that’s truly the limit as I see it for this combination — and some of the current internals of the engine build.”
As any engine builder knows, keeping the inlet air cool is key to big power. With the Edelbrock supercharger, inlet air at cruise is only 5 degrees over ambient and peak temp after a dyno pull is 150 degrees F. Clearly this combination is perfect for all performance duties. But despite Montague’s impressive dyno numbers and record-setting customer cars, he retains some humility, a unique quality that makes his efforts all the more impressive. Notes Montague, “I don’t refer to myself as an expert, but a Master in Training. I still have a lot to learn.” Don’t we all.
From this view, Monfortes’ Charger Daytona hardly looks like a sleeper, but the car’s full potential is hidden deeply underhood. Hellcat snobs beware.
The handwork of Adam Montague and his team at Spankin’ Time Motorsports, this 6.4L engine has been reworked to emit 840-plus rwhp. For those wondering how that ranks with the highly praised Hellcat, nearly 300 rwhp more. This red blow-by separator unit keeps the oil out of the fuel system.
The factory Brembo brakes do a great job of stopping the Charger. As per the theme, Monfortes painted the calipers yellow.
To give the front end a performance look while increasing the car’s ability to cut through the air, an APR splitter from Wicker Build was installed. The side reflectors were “smoked out” to add to the all-business look, and a K1 Body Kit included all of the other body dressings.
The massive rear spoiler applies significant downforce to the rear tires to aid traction and provide a purposeful performance look.
The massive diameter of the rear exhaust tips provide some clue as to the performance potential of the Charger.
The neatly detail trunk includes this ethanol kit, which is tucked into the driver-side compartment.
While the suspension utilizes the stock shocks, Rob at Big John’s Performance in Valencia, California, helped Monfortes into a set of Mopar Race Springs that greatly help weight transfer at the racetrack and deliver a decent ride on the street.
The carbon-fiber hood is super lightweight and provides three function heat outlets to keep things cool at all times.
The license plate says it all – 392cid – number-one supercharged and very fast Daytona.
