Project Hemi-Hauler: Supercharger & Exhaust - Truck Tech S3, E3

it's black it's big and it's got a Hemi the guys will upgrade this 5-7 ram with a root style blower an exhaust for more power then roller on the dyno for proof that's all today on truck tech [Music] just a few years ago this half-ton pickup was named Truck of the Year by several national publications it's a 2013 Ram Hemi 1500 sharp looks decent power and great towing capacity still make this truck very popular today and a lot of that has to do with price the sticker on this 2013 with only 8,000 miles was just under 20 grand and that's great value especially when you compare it to a Cummins at over twice the cost yeah you get way more towing capacity out of a diesel but we think we can improve this bone-stock gasser with a few performance upgrades and maybe even improve the looking stance of this truck as well let's take it for a ride well we're riding around in this 2013 Ram it's got the 5-7 Hemi right yep 517 yeah you know pretty good power think they rated it 395 and a a little over 400 foot-pounds of torque so I mean it'll be a stock truck that's pretty impressive one thing I've noticed I really like about this truck is the electric steering in it I mean it's almost like you're in a sports car you get into these curves I mean you can literally steer this thing with one finger it is absolutely effortless and speaking of the chassis I mean how does it handle we're on a nice curvy road here is the suspension pretty tight you know it's it's pretty tight it's a guess maybe because I'm a lowrider guy would like to see it a little lower to the ground but I mean to be a stock truck still up in the air like it is it does handle pretty good there's not a whole lot of body roll there and you know there's a lot of upgrades we can do it you know the suspension and everything to you know improve the ride and improve the towing capabilities I'd be all for that so long getting it a little lower to the ground and you know I think this thing's rated it like 10,000 pounds for towing capacity so get a little lower to the ground and I'm sure we can do some air helper springs or something to kind of help help any leveling out we need well speaking of towing I hit the brakes real quick let's see how this thing stops oh not good no not at all but you know what even though even though it stops pretty good spendin stock trim I bet if we throw some rotors and Pat upgrades in there I bet it'll stop even better boy the trailer and it'll stop better time after time after time sure [Music] back at the Tech Center we're on the chassis dyno at engine power now operating vehicle on a chassis dyno can be dangerous if you don't take the proper safety precautions among other things my pre dyno checklist always includes a walk around of the vehicle double-checking the straps before I spin the rollers and a quick inspection of the tire pressure Jeremy you ever run struck on the chassis dyno before not sitting in the driver's seat ahem well it's not too bad lorig news we're gonna ring it up to about 4th gear that's closest to one to one ratio on your transmission we're gonna start the test about 2,000 rpm is and all you do really from there is hit the green bud and kind of get on to it well not too bad about 305 horse at the wheels and 324 foot-pounds of torque that's not bad for a stock truck but I won't I want more power though I don't blame you numbers will vary as the truck gets up to temperature so we'll do several runs all right the second run a little bit less we got 300 horsepower even and 334 foot-pounds of torque let's do another run and we'll get ourselves a good three run average and lastly we've got 310 horsepower and 335 foot-pounds of torque not bad at all that gives us a three run average of 305 horsepower and 331 pounds of torque numbers we certainly can't improve on with some power adders under the hood and the guys will do that next with a step-by-step supercharger install we've got some serious upgrades planned for our 2013 Hemi Ram and now that we've got it in the shop we can get started that's good kill it we're gonna be addressing the stance the load carrying capacity but first we're gonna get some power to this thing now over on the dyno we averaged 305 horsepower and 331 foot-pounds of torque to the rear wheels now that's respectable for a stock truck but we know we can do a lot better this 5.7 liter Hemi is a great foundation for what we have planned this is Edelbrock's e-force supercharger for an O nine through 14 Ram 1500 Hemi and it utilizes Eaton's gin 60 vs 2300 rotors the seven inch long runner allows for maximum low-end torque which is great for us as we plan on doing a lot of towing with this truck Edelbrock's designed their supercharger with an integrated liquid to air heat exchanger this is great because it's gonna minimize our Inlet air temperatures and it's gonna maximize our performance and the great thing we love about this kit it comes with everything we need to install it and we're gonna start by installing the updated calibration inside this tuner provided with the kit let's get started alright the first step is to plug the connector into the obd2 port underneath the dash board once you have that connected and the key in the run position you simply follow the on-screen instructions to program the computer this particular tuner will actually make a copy of the RAM stock tune file and save it inside just in case you ever decide to return the truck back to stock some of the major changes inside this new calibration are for the injectors which are much larger than stock to accommodate the higher power level the first step under the hood is to disconnect the battery after removing the grill the first major part to come off the engine is the intake manifold it's fairly straightforward there are a couple of PCV and vacuum hoses to remove disconnect the plug for the throttle body all eight injectors and the map sensor with a retainer disconnected will remove the fuel line and have a rag handy to catch the overflow then remove all the bolts that hold the intake manifold to the engine get rid of this it's always a good idea to clean off the mounting flange on the cylinder head and cover the runners with tape so you don't accidentally drop a bolt inside to break the fan loose we needed a special tool but since we didn't have one laying around the shop we made our own the two tabs on the tool key into the holes on the pulley we left the belt on for this step to also help keep the pulley from turning once the fan is loose go ahead and remove the belt now remove the alternator next we'll drain the radiator move the upper radiator hose and tie it out of the way then pull out the fan shroud and the fan together the reason we're taking everything off the front of the engine is to gain access to the crankshaft on newer engines there's actually no key way that'll hold the crankshaft pulley to the crank itself now these modern accessory drives really don't take a ton of power to turn there's just no need for one but when you add a supercharger into the mix the added drag can actually cause that crank pulley to slip on the crankshaft and cause damaged so to prevent that from happening we'll use this kit from Edelbrock we'll pin the crank and we'll solve all our problems [Music] using this supplied fixture we are drilling a hole exactly between the crankshaft and the hub of the balancer after the hole is reamed to size a [Music] little green Loctite is applied and the pin is driven into place preventing any movement of the crank pulley will replace the factory bolt and torque it to spec there are three main types of forced induction and choosing between them can be a little bit confusing so let's talk a little bit about their differences and why we chose what we did for our 2013 ram a centrifugal supercharger is a very popular option it's a belt driven impeller and it produces a very linear boost curve proportional to engine speed what this means in layman's terms is that low engine rpm you'll have a low boost pressure and as the RPMs climb so will the boost this would be great for a high RPM street or race motor a turbocharger looks very similar except instead of a gear drive it uses a turbine driven by the engine exhaust gases because of that there is some time delay between when you step on the gas and when the boost builds up this is known as turbo lag on a properly designed turbo system the lag will be minimal and the boost pressure will rise quickly and then taper off at the desired level now turbos are great for all-around sporty street vehicles but a route style supercharger is a type of positive-displacement blower and is an entirely different animal driven by the crankshaft it uses interlocking helical rotors that will pump air into the engine what this means is boost comes up almost instantly to its peak when the throttle is hit and will maintain throughout the entire rpm range this boost curve is why we chose a route style supercharger for our 2013 Rams towing application the instant low end torque and response is something that a centrifugal supercharger or turbo just can't deliver coming up there she blows bus dyno proven power stay tuned you hey welcome back now that we've got disassembly all complete we've got our crank pin it's time to start the fun stuff we'll get this protective tape ripped off slide that big supercharger into place all right it's about time let's get this thing on I'm ready for it we didn't forget the gaskets a good tip especially if you're doing this job by yourself lift one side up at a time and slide the gasket in this is a great way to do this to help prevent tearing the gaskets you know end up next get all the bolts in a few threads or so just to make sure everything's lined up snug them down then torque the bolts to nine foot-pounds the next step is to install our injectors in the fuel rail now since we don't want to take a chance of tearing these o-rings by inserting them dry we'll give them a little square root of wd-40 they all to slide right in [Music] don't forget before you install the rail to lube the other end of the injectors as well once the passenger side rail injectors and rear cross over to bar installed right we can move on to the front of the engine by reinstalling the fan and shroud the shroud slides down into plastic retaining clips on the radiator and is secured by two bolts [Music] reconnect the upper radiator hose and line up the spring clamp to its original position our custom tool comes in handy again for tightening the fan clutch we can now add the last fuel line that connects the fuel rail to the body of the truck well the alternator is still out we have access to connect the vacuum hose for the brake booster and the evaporative emissions line Edelbrock includes a larger idler pulley for improved belt wrap on the supercharger which minimizes belt slippage we can reinstall the alternator and hook up its electrical connections then the supplied belt can be routed around the pulleys the factory throttle body is reused but not the o-ring Edelbrock supplies a new one and with that in the front of the engine is done you may have heard the term intercooler or heat exchanger when talking about supercharger systems and wondered what that's all about well anytime you compress a gas like air to force it inside an engine for more performance the byproduct is always heat that heat can quickly lead to detonation which will damage any engine now in order to prevent this that e-force supercharger includes a liquid to air heat exchanger to pump away that extra heat an electric water pump is mounted near the frame rail with the included brackets this makes for a nice no drill installation the pump draws liquid coolant from the reservoir mounted high up on the engine and forces it towards the front of the vehicle Edelbrock's supplies some nice brackets to mount a radiator or heat exchanger in front of the engine's radiator so it can transfer heat away from the coolant and into the atmosphere the cool liquid then continues on into another heat exchanger mounted inside the supercharger the liquid carries heat away from the supercharger and back out front for another trip to be cooled off Edelbrock recommends that you recap your spark plugs to 35,000 but because this truck has 60,000 miles on it we're gonna go ahead and replace them with new ones and since we're gonna be in there removing our stock coals to get to those plugs we decided this was a great opportunity to go ahead and upgrade to these MSD coils for the Hemi these are MSD blaster coals and they're made out of upgraded materials and windings which create a greater spark now with a stronger spark you're able to burn fuel more efficiently which creates more power the plugs in ignition coal are straightforward to install and I like to do just one at a time and remember whenever you're putting in new spark plugs use a little anti-seize a cleanable High Flow air filter drops right into place followed by the PCV hose then the inlet to the heat exchanger pump harness goes on next Ella brach supplies the harness pre-terminated so there's no cutting or guesswork now the negative battery cable can be installed new coolant from autozone goes into the heat exchanger and we reuse the factory coolant in the radiator the factory grille is a snap to reinstall and four bolts hold the top edge the header panel clips on top of the radiator and this finalizes the supercharger installation all right Jeremy hit the key on let's check for fuel leaks fire right up I would say we're successful you we'll need some gauges to keep an eye on how the engine is running we got this a pillar pod and fitted with these gauges from Summit Racing up top will be our boost gauge and on the bottom will be our wideband air/fuel ratio gauge this way we can ensure that the engine is always running at proper fuel mixture we will start by removing the a-pillar trim then get an idea of where we can run the wires for the gauges we'll start with the boost gauge as it's the easiest all it requires is a solid line put real slow run to the MPT port on the side of the supercharger and a switch 12-volt power source for the lights be sure to run the lines out of the way of any heat or sharp edges underneath the truck we have to find a location to mount the oxygen sensor before the catalytic converter drill a hole for the provided bung deburr the surface and weld it in after the weld cools tighten the oxygen sensor and plug it in and the gauges are done the last performance modification we're going to make to our ramp is exhaust Gibson offers this split rear exit stainless steel catback that will fit perfectly in the cutouts in our Rams factory bumper it features mandrel bent construction for maximum flow without any restrictions and the best part is they're super flow performance muffler will let our blown Hemi operate at its peak and it'll sound great while doing so we begin by using wd-40 to lube up all the rubber hangers to make the exhaust easier to remove we'll get the stock tailpipes out of the way by cutting them off at the rear of the muffler with a sawzall and then we can slide them out of their hangers unbolt the clamp at the factory catback connection and we'll need a little persuasion to separate the pipes and remove the muffler there we go the new system goes into place just like the factory one came out starting with the muffler and then the tailpipes will install everything loosely at first check the alignment of the polished tee 304 stainless tips then tighten everything down for good nothing sets off your project truck like a freshly chromed or painted bumper you can spend weeks scouring junkyards hoping to find a decent core to be cleaned up and rechromed but be prepared to open your wallet since this process can be expensive lMC Truck offers Oh equality steel bumpers that are brand new and ready to bolt on they come in replacement grade chrome or this extra buff premium nickel chrome for around two hundred dollars or if you're on a budget once improper ready to paint for less than a hundred bucks go to lMC Truck com for more heat is often the killer of power and performance design engineering combats the heat with our titanium products line of wraps shields and boots it's made from pulverized lava rock and stranded fiber woven into a protective barrier for fuel and brake lines hoses wires even turbos from direct temperatures up to 1,800 degrees we used it to wrap our diesel exhaust which sits right next to transmission cooler lines dei titanium products are available at most automotive retailers we couldn't in the day without strapping our Hemi hauler down to the Nano to compare numbers now these Edelbrock supercharger come out of the box ready to make big power but you guys know how we operate here at truck Tech we just can't stand to leave anything alone so we threw on a smaller pulley from Edelbrock to increase our boost and by doing this we need a custom tooth so we called Alex from pipes performance tunes out of Houston Texas he's an expert at tuning Chrysler's especially boosted Hemis well the tuning software I'm going to use and what I prefer to use in anything I tune is HP tuners traditionally dodge has always made it a little more difficult however with HP tuners and their great engineering team they have there it makes it easy honestly after making three pulls to 6000 rpm we averaged 431 horsepower and 434 pounds of torque overall that's a gain of a hundred and twenty-six horsepower and 103 pounds of torque to the wheels and we're still not done with this Ram we have a lot more left in store for Hemi hauler
