LS vs Coyote 2, Episode 4: A Winner Crowned In Dramatic Dyno Session

In a dogfight on Westech's engine dyno, the LS and Coyote engines are dyno tested in a quest for victory in the competition. LS vs. Coyote 2: Boost, is a competition where two teams were given $15,000 budgets, plus ProCharger superchargers, in a quest to make the absolute most horsepower per dollar allowed in a brutal dyno test. Budgets were pushed to the limits in order to win. Top engine builders, LME and MPR, were both were given the platform (LS and Coyote) and a common set of rules to build on - which included VP C85 fuel, up to 12-rib serpentine belts, their choice of any ProCharger, and hydraulic roller camshafts (among other things). These teams were challenged to make the most horsepower possible on a fixed budget. Things got dicey in the room, as both builders tried to push the limits and the rulebook in ways we didn't even imagine.

The funny part is all but the 4.8L vortec would likely have also beat the Coyote (edit: meaning 5.3/5.7/6.0/6.2 would, 4.8 wouldn't), if specific output was similar. Would saved a lot of cash.

[@brianfrost303]

I'm shocked. Shocked i tell you!! Never in my wildest dreams would I have guessed that a 427ci with aftermarket block, crank, heads and a 10 rib belt driven blower would make more horsepower than a 302ci motor with factory block, crank heads, smaller blower with a measly 8 rib drive.

I own an LS and Coyote. LS is a great engine for its exterior dimensions. Coyote is a great engine for its displacement but is physically huge. Comparing a 427 to a 302 is like comparing a small block to a big block and then acting surprised when the big block makes more power. This video is a stupid comparison. Lets see a stock internal 5.3 go against a stock internal 5.0 if you want a valid comparison.

Funny that the coyote is both bigger and heavier than the LS. So which motor is really "bigger"?

[@stefanl5183]

" it’s what Chevy has available vs what ford has available" No! Ford has an RY45. The RY45 is a wide bore pushrod engine that can support large displacement just like the LS. So, why not put the LS up against the RY45 instead? That would be better comparison. By the way, the RY45 has already taken on Chey's finest and beat the crap out of it. Look no further than Dirt late model racing. Want to be competitive against the likes of Josh Rchards, Scott Bloomquist, and Brandon Shepard? Your not going to do it with an LS under the hood. If you look under the hood of those cars, you'll find they are almost exclusively RY45's. And as for why displacement matters, in most forms of racing this is one of the metrics they use to define the limits of a class. If you decide to go racing at your local racetrack, you'll most likely find that their classes usually have some displacement limit that defines then. If not, then just get yourself a Sonny Leonard SAR1005 and be done with it, 1000 CID and 2100Hp naturally aspirated!

[@gavwilldo]

Love how the ford fans talk about the capacity difference, of coarse bigger is better, why would anyone prefer a smaller capacity larger physical sized engine for the same $ and make way less power

[@terraboundmisfit]

CID wasn't the point DA!

[@danielbrealey2924]

True, but they dob't want to hear "sensible"... They all live in dream land and just windge and bitch that it'd "not fair" because the LS is larger capacity. No one cares sbout hp per cube. It's total and average hp that counts. It's also funny that there are people complaining that they didn't get into an RPM range where the Coyote makes power! I wonder why that is? Maybe because the timing chain shit the bed at relatively low RPM for a DOHC engine. They just don't WANT to face reality

[@justinanderson8394]

Daniel Brealey well it didn’t make as much power it should have because of belt slip, coyotes live way up high and the fact they didn’t allow a cog really hurt it especially. Plus too they decided to use a stock timing chain, hopefully we will see the engines at there fullest once they are back up and running

I think the engine builders got to pick the supercharger based on what they said in the video. Procharger and the coyote builders chose the smaller supercharger. Kinda wish the rematch would have gone with the f1x that the LS used instead of f1A94. f1a94 says it is good for about 1300HP and really that is what the coyote made. Time to go bigger I would say.

AND FOR WHAT. When a fella can build a cheaper, easier, more reliable motor with MORE cubic inch power potential that can live through certain failures such as pushing a head gasket. That LS only needs the deck & head resurfaced, along with the ARP head bolt upgrade. Now it's gonna cost a small fortune alone, just to fix that Coyote motor. There's just too many moving parts in that INTERFERENCE design of the Coyote to cause catastrophic failure that is much harder to do to the simpler, more reliable LS platform.

Yeah but with pro chargers, the higher the rpm the higher the boost provided your belt don't slip. Usually the coyote rpms 1500-2500 more then LS motors can. And it was not that much smaller of a charger. It just looks small because the 5.0 is a giant engine.

[@SoundFaithStudios]

@@matteatmon5558 it's easier to manage traction with a engine like the coyote. Makes peak torque high in the rpm range. The wheels have more time to gain speed before peak torque occurs. In the LS's case, 1500 lb ft of torque at probably 4k or less is a tire shredder. Nearly unusable unless you have a chassis, suspension and tires to match.

Bryan Mayes if a 4.8L is left a 4.8L it would not destroy a 5.0L coyote regardless of budget.

Yeah, usually in a supercharged motor, it's better to use more boost and less compression. no matter what fuel you use. If these guys knew much about engines, you'd think they would know this. More boost increases dynamic compression, but it also packs more fuel and air into the cylinder. So, boost trumps static compression when your goal is to make more power!

Wesley..........You're speaking complete NONSENSE. It's painfully obvious that you have no clue what kind of punishment they just put these 2 engines through on that dyno. Besides, there were NO plans of running them on a race track, and besides, the numbers don't lie, the LS would've won anyway. There is no replacement for displacement. Cubic inches always win when both platforms have the same power adder budget. Furthermore, you can't blame the LS engine over a lousy FACTORY STOCK HEAD BOLT FAILING. And no one being totally honest can give the same pass ( good excuse ) over a broken chain on the Coyote, because MANY other internal parts were destroyed due to the design of the Coyote being an interference motor. When something breaks, usually A LOT OF OTHER SHIT is going to break right along with it. In other words, it's going to cost a small fortune alone, just to fix that Coyote motor. The LS only needs resurfacing the deck & head, and new gasket, and then use REAL performance head bolts from ARP like they should've done to start with. Hell, they could've sacrificed by choosing a more economical yet nice high performance intake to cover the cost of the head bolt upgrade, and STILL would've remained within the budget limit to make far more power & torque than the Coyote motor. Perhaps less power with a cheaper intake, but still would've been plenty to beat out the Coyote. Folks, these are perfect examples of why the mighty LS platform is the #1 choice for engine swap all over the world. Cheaper, MUCH easier to build, tons of after market performance support to match any budget, and the engines can live through more failures with less cost to repair.............WITH MORE CUBIC INCHES. This is street/strip racing in the real world.

Building a $35k to $50K engine (ok 15K in parts, +9K blower, and of free labor and machine work) and then blowing them up after a couple of pulls makes the engine builders look like idiots. They should know how to build engines for a given hp range without it breaking on the dyno like that. They should know the limits for their build. If they don't then find another builder.

These comparison videos are very interesting, but they always (at least partially) measure the wrong things, especially when comparing motors with significantly different performance characteristics (especially different rpm ranges). Modern car enthusiasts are starting to properly understand power, torque, how gearing makes torque X rpm (= power) what really matters, and what it takes to actually compare real world performance. To give us a "Real World Winner", why don't you measure and compare the things that really matter, such as (I've also tried to explain why for those old school among us): 1. Peak power & torque. These are really only useful numbers for boasting about (and are worth measuring for this reason). There are very few applications where the motor can always be run at the peak power rpm all the time (CVT transmission, a well setup boat, top speed run, top fuel drag car slip clutch, and not much else). Peak torque might give us an idea how well a motor can move a heavy load without having to rev high, but only when multiplied by rpm does it provide real world useful information since we enthusiasts are willing to make our motors scream (run a 2:1 gear after a motor with 1/2 the torque at twice the rpm and you're back to the same...). 2. Average power over a 50% percent increase in rpm. Average power over a range of rpm is what really matters to serious car enthusiasts. To simplify things, say we have a manual gearbox and need to accelerate from 40 to 60 mph in 2nd gear and then 60-90 in 3rd, then 90-135 in 4th, then 135-203 in 5th. With this vehicle, the engine rpm increases by 1.5x (50%) while in each gear (most manuals and automatics with less than 5 gears average around a 50% rpm increase per gear). One engine may make its best power revving from 4000 to 6000, while another engine might perform best from 8000 to 12000 rpm. With the right gearing it doesn't matter what the actual rpm is, but the percentage difference or ratio between the lowest rpm after a gear shift and highest rpm right before the next shift is what matters. So a very useful measurement would be average power between an engine builder's chosen rpm and an rpm that is 1.5x (50%) higher. In this case the LS might perform best between 4500 and 6750 rpm and the Coyote might perform best between 5600 and 8400 rpm. Calculating the average power over those particular rpm ranges would give us an excellent measurement on how they will perform in the real world. 3. Average power over a 25% percent increase in rpm. Older 3, 4 and 5 speed transmissions needed to increase the rpm by a good 1.5x (50%) per gear, but many modern vehicles have even 10 speed transmissions and need a much smaller rpm increase during each gear. It would be useful to do the same measurement as #2, but with something like an increase of 1.25x (25%). An LS might perform best between 4720 to 5900, while the Coyote might like 6560 to 8200 for the 1.25x (25%) rpm increase range. These measurements (#2, #3 and #4) are far more important than peak power because they measure and predict real world performance. For example, an LS that makes 250 hp at 4500 rpm and 1000 hp at its redline of 7000 rpm, with most street transmissions, will be blown away by one that makes 650 hp at 4000 rpm and 750 hp at 6000 rpm because the average power is much better with the 750 hp motor. People often get confused and say it is peak torque that matters when accelerating, but it is always power that matters. Power just needs to be measured and averaged over the rpm range used. 4. Average power over a 15% percent increase in rpm. When building an all out drag racing car we'll probably have a torque converter that stalls somewhere around 1000 rpm below redline. For example we might have a 6000 rpm stall torque converter with a 7000 rpm redline and a 6900 rpm shift point & 1/4 mile exit rpm so our rpm will always be above 6000 rpm. In this case average power between 6000 rpm and 6900 rpm is what we need to measure. To compare different motors with different rpms, when using this type of transmission setup we now want to compare average power over roughly a 1.15x (15%) rpm range. 5. Rotating inertia of the engine. When accelerating down the track, some of the power goes to accelerating the rpm of the motor itself. Motors with heavy crankshafts and heavy flywheels can waste enormous amounts of hp, just accelerating the rotation of the engine itself. This is why installing a light flywheel, balancer, etc. improves 1/4 mile times. Similarly V8s with lightweight flat plane cranks often have a significant advantage over ones with heavier cross plane cranks. One way or another this should be measured and compared. One "fun" (but still valid) option might be to accelerate the engine on its own between two rpms a percentage apart, similar to the real world power measurements; Say 4000 and 6000 rpm (50% higher) for an LS and another pair of rpms (higher rpm 50% higher than lower rpm) for the Coyote and measure the time in 1/100ths of a second. 6. Width of the engine. 7. Length of the engine. 8. Height of the engine. 9. Mass (weight) of the engine. 10. Specific fuel consumption (hp/fuel burn rate) 11. Cost of the engine (in this particular comparison not required because of the $15k build price for each). 12. Power per displacement (hp/liter). For street vehicles this is really just something of interest or to boast about. For racing, where displacements are often limited per racing class, it is useful to know which type of engine gives us the most power per displacement. Typically more advanced, better "breathing" engines generate more power per displacement, but sometimes more advanced engines suffer from additional complexity and are more difficult and more expensive to modify for maximum reliable power. A perfect example, the Coyote has 4 valves per cylinder, 4 camshafts, 4 timing chains, etc. and is physically larger compared to the LS with 2 valves per cylinder, 1 camshaft, 1 timing chain, etc. The above measurements would give us all of the real world data needed to truly compare and decide which engine is better. To turn it into more of a competition you could apply a weighting factor for each measurement, add them all up, and decide on a "Real World Winner". For those with physics PhDs reading, yes I know average power is a simplification of the integral of power over time, but this "approximation" is still a far, far more accurate way of measuring and assessing real world performance when compared to the peak power and peak torque measurements we are typically provided with.

The coyote would kill the ls if it was the same size as the coyote. They coyote can spin higher rpm and is a much more efficient engine. This motor would have made much more power if it had a cog belt setup also. It wasn't able to take advantage of the high rpm because of the belt slipping so bad. The ls doesn't spin as high so the belt slip was much less. If that's part of part2 where they both run a cog setup and both head units being the same these motors are going to be much closer. Either way you can't lose with either one for them.

[@clutchkickpj693]

I mean that's a more logical comparison but Ford doesn't have a 7 liter coyote lol

[@waynebollentin989]

@@clutchkickpj693 they rely on the rpm and DOHC instead of the cubic inches. If you can spin the motor higher you can make more hp with less cubic inches. It's why the coyote does as well as it does. You go back to the 3.8 v6 by Buick and they made 1400hp+ in the 80s and now 2000hp same with the 2JZ'S. Rpm makes up for cubes. When you can combine both rpm and cubes then you have a really bad bitch on your hands. Then there isn't a replacement for displacement lol..

[@taylorgtrotter]

So we learned that a 99.9% aftermarket LSX with Brodix heads, a larger supercharger, and 120” displacement advantage can beat a stock block and heads coyote with 120” less displacement, and a smaller supercharger in a dyno race. We also learned that the LSX needs every single one of those advantages to surpass a coyote. Yes Dohc heads make up for lack of displacement, but only to a certain point. Way to keep it non-biased Power Automedia. (Sarcasm) too much to ask for a non-biased test where one engine doesn’t get a huge advantage?

[@my87z28]

You’re viewing this as a comparison. It’s wasn’t, it’s a competition between platforms given a specific budget. Only the budget stopped MPR from boring and stroking that coyote. Also, don’t be mad at the producers at the fact that GM has a much larger aftermarket following than Ford does. Be mad at the aftermarket developers.

[@mikevanmeyl123]

$15k to build a 427 lsx aftermarket block and machine work get off the pot

[@stefanl5183]

@@my87z28 Let's see the LS go up against an RY45. The RY45 is still a small block compared to the LS being a big block, but at least it's a wide bore small block. That would be a more apples to apples comparison and it would wipe the floor with the LS just as it's already done in the world of dirt late model racing!

[@tortol4847]

So basically you don't want one engine to have an advantage. Which is why you would prefer something like a 5.0 coyote vs a 5.3 ls... at which point you would turn your cheek to the fact that the coyote would have a significant advantage because it is dohc. So more or less you want a competition with perfect parameters for your favorite participant to win. Not really a competition if you ask me.

[@taylorgtrotter]

my87z28 I purely looked at it as a competition. Can’t bore a coyote past 3.7” where that motor already was. The stroker cranks are only so big, producing 327” engine. That still wouldn’t have given the coyote another 370+ hp. Then there is the blower part of the equation. Coyote heads don’t need aftermarket castings, they’re great from the factory. That aside, there’s a very large aftermarket for coyotes.

In Factory Stock racing the 5.2L Cobra jet entries have dominated so far in 2019. In a field of 11 Fords entered to 17 COPO Camaros and 3 Dodge Drag PaK Challengers at the Gatornationals. After three rounds of qualifying the Cobra Jets held down the top five spots, with Bill Skillman setting the pace at 7.74 at 172.96 mph. Bill was trailed by Carl Tasca (7.75/178.24); Chris Holbrook (7.77/178.05); Randy Eakins (7.78/178.64); and Drew Skillman (7.82/175.11). Skillman went on to win the event. Yes, the little Coyote can hang.

[@nathan22outdoors8]

We know the coyote can hang.... thats kinda why all the fanboy excuses saying it has a displacment disadvantage is completely irrelevant.

Really? NHRA is making that their form of WWE, they control that shyt week to week with BoP to keep everyones interest. It literally proves nothing. "Note: NHRA may make adjustments to (minimum weights, supercharger pulley ratios, etc.) at any time to control performance and maintain parity within the category."

[@EGGINFOOLS]

I mean, did the DOHC guys really think they would win? The LS made more torque than the coyote made HP. 🤣😂🤣😂

[@177SCmaro]

I hope the LS won. It had over 100ci on the 5.0 (not to mention a bigger supercharger running more boost). What's telling is the 427 didn't win by a very big margin. Lets you know how well those 4v engines run for their size.

So you say 5.3 makes 1500+ but that's a built 5.3 but then your mad that you would expect a smaller built 5.0 to make more hp? Your expectations are pretty flawed buddy. Fyi that coyote was nowhere near done with how much more hp it could have made if it didn't have a timing failure.

[@jmtmotorsports3173]

Coyote is a stout motor that may be able to win a battle here and there, but it’ll never win a war! To small and to many little moving parts to fail. Can’t match the efficiency of a monster LS either... Grandpa didn’t tell y’all “There’s no replacement for displacement” for nothin! And in my opinion, If you wanna compare apples to apples, Horsepower Wars 3 can be a 5.3ish coyote vs 5.7 LS1, both built and with budget boost again. Ford fans can’t really cry cubic inch cuz history has shown since the 80’s, even earlier, it was a 302 Mustang vs a 350 Camaro.

[@thedude4632]

JMT Motorsports ya you did not compare the 351 to the 350 . I almost always go for the under dog . Your test is bull shit , not a clear winner, cubes must be as close as possible. Your test a 427 compared to a 302 is 105 cubes is a bull shit comparison means nothing . Get real .

[@HioSSilver1999]

Why would you ever run the same size blower on a better flowing engine? Gmc knew back in the 1930s you don't run the same size blower on all engines.

[@bobloblaw7465]

You failed to understand the rules and premise of this video

[@joshheinz5328]

Same budget, same target customers. The engines stock have more than a liter difference between them; pushrod engines have higher displacement for the same power. But that only matters when entering certain racing classes. For real world, real life use, a lighter engine, with smaller external dimensions, with a lower weight/lower CoG is preferable. On that note, kinda funny how they used an engine with 4 times the camshafts, and much larger physical dimensions.

[@joshbrown811]

So? they compete directly with each other and they had the same budget for the comparison. The 5.0 also has to rev higher, more complicated, and is physically larger.
