    • Comparing the 2016 Ford Shelby GT350 Voodoo V8 to the best naturally aspirated performance engines of the past decade with specs and dynographs

      Ford is doing something very special with the new Shelby GT350/GT350R Mustang. What is so special about it? That in this day and age where emission regulations are tightening (and even toppling automotive giants) Ford is able to deliver what many companies including BMW say can no longer feasibly be done.


      Well, Ford proves you can deliver a high performance and high revving naturally aspirated motor that is emissions compliant and do so in an economically viable manner. The manufacturers that said this could not be done simply wanted to pad the bottom line further.

      The Shelby GT350 Mustang starts at just under $50k making what Ford achieved here even more impressive. Keep in mind that every single engine on the list below was put in a car with a higher starting MSRP and in some cases by well over $100k above the GT350 starting price.

      As reported yesterday, the GT350 5.2 liter Voodoo V8 makes 467 horsepower to the wheels and 374 lb-ft of torque at the wheels. The BoostAddict network a few months ago compiled a list of the highest revving motors regardless of aspiration in 2015. Now let's compare the best modern naturally aspirated performance engines produced in the past decade in the context of the new Ford GT350 V8 with their specifications plus Dynojet output.

      Now some of you may be saying, hold on, where are the big naturally aspirated V12's from Ferrari and Lamborghini? They make more power! You are right, they do. They also come packaged in $300k plus cars. That highlights a key point here. Ford is offering by far the most naturally aspirated horsepower per dollar. It isn't even close.

      Also, we wanted to compare the motor to actually attainable cars and vehicles closer in displacement and cylinder count. Obviously it is not uniform and obviously cars like the SLS Black Series are many times the cost of a GT350 but that just serves to make the GT350 look even better.

      The Voodoo V8 is the third most powerful motor on the list. It makes more power and torque at the same compression ratio with the same revs as the vaunted BMW S85 V10. It also does it for less money at a time when emission rules are tighter.

      BMW has switched to turbo motors because they said they can no longer make high performance naturally aspirated high revving engines that meet emissions standards and still make money. Yet Ford is producing a naturally aspirated motor today that makes more power and torque than BMW's best for less money than BMW. Hey, you figure out if it is because BMW can't do it or the accountants who run the show prefer that they didn't.

      What we also learn here is that Porsche by far pushes their engines harder than anyone else. They are the top dogs when it comes to extracting horsepower per liter followed by Ferrari. That said, the 991 GT3 is the champion of hp per liter and Ferrari is almost a full 20 horsepower per liter off from them. That is a large gap and Porsche deserves tremendous respect for what they do. Yes, the list is missing the 458 Speciale which certainly would be great to see and if anyone has a Dynojet run for one that Ferrari didn't pull from the web let us know.

      Ford is offering the best balance of revs, horsepower, and torque for the money in this comparison. The Voodoo V8 is truly elite only giving up two wheel horsepower to the Lamborghini V10 which comes in a car over $200k while also offering more torque. Only the SLS Black Series M159 tops it significantly but it is working with another liter of displacement and costs $300k+.

      The Voodoo V8 truly is world class. Ford can not get enough credit for what they have built.

        Definitely a good one. Hopefully people notice it and don't dismiss it because it isn't focused on the Germans. Plus it took a bit of time to compile.

        Not to blow smoke up your ass, but this is why I come here. Clearly I'm an N54 fan, but I love cars in general. BA is a one stop shop for me.

        Well this is why I do it because there isn't any other forum that satisfies me or presents things the way I want them. No bans is a plus too I suppose.

        Great article! So, 15 years later the s2000 still holds the title for NA HP/Liter? The Honda kids were right the whole time... V-tec, yo!

        Gotta keep in mind Sticky is comparing WHP per liter. Not sure what stock S2000s dyno'd at, but I'm betting it would have been mid pack behind several of the Ferraris and Porsches above. Plus, I think the RX8 stole away the S2000s crown and would likely still be at the top of this list as well. But, neither engine had much torque - ok for a track car, not great for the street (where 90% of S2000s and RX8s were driven). Not knocking those engines - they were both just different beasts than the engines above.

        You're right! I missed that and was totally off. I'd have to imagine the f20c makes about 100whp/L so its still up there with all the best, less Porsche.

        Stock S2k's dyno right around 200whp and the AP1 was 2L so they aren't top but they are basically the same as the 458's V8. AP2 adds 0.2L of displacement but only like 10whp extra. Not the top but still impressive.
        RX8 is rotary and very misleading calculating specific output per liter. Its "displacement" is only calculated from 1 rotation of the output shaft vs 2 rotations for a 4 stroke piston engine.

        HP/Liter also always favors the smaller motor since they have less frictional/rotational losses while the more surface area/weight hampers the bigger motors but they have an advantage reaching higher total HP

        Perhaps it's a stupid question, but what octane rating do they tune all these cars for? Our premium varies from 93 to 91 which is quite a difference when running a high compression ratio motor. Forced induction, well that's easy enough to tune with pulleys and wastegates.

        Very interesting, but it shouldn't be an issue with proper gearing, but it could be something that would effect a 5th gear pull.... I'm sure tuners will solve it a few hours after taking possession, regardless.

        Exactly what I was going to write. If we included motorcycle engines here it would look completely different.

        The displacement makes the Ford V8 look even better.

        All of these motors are designed to run on 91 octane pump and even account for the random idiot that fills up with 87.

        There was a time when forum experts would say you would never see a 12.0:1 compression production motor on pump gas.

        I'm not sure if I'm more excited to see what this thing will do with ~7lbs of boost or a ragged edge, all motor, build. Should be fun either way. Also going to be cool to see these swapped into the older Fox bodies that weight a hair over 3,000 lbs.

        It's going to be exciting to see everything it does.

        I'm interested to see what it can do all motor. It doesn't have quite the top end of a 458 Italia but I'm sure someone in the Ford aftermarket is going to get some cams for it and even more revs out of it which would be crazy considering the stroke.

        With boost I'd expect an easy 700 whp on pump at 7 psi or so.

        700whp was roughly my guesstimate as well... the great thing about this is that you know people are going to push the hell out of these motors as soon as they get their hands on them. It won't be like the Ferrari V8's where you have to scratch your head and wonder 'what if someone did an all-motor build?'.
