oooooo I want to see this go down so bad.

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 ration 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.

Hmm competition makes everyone better. I like what I am seeing.

The argument of hp or tq per liter is ignorant.

How so? It is a pretty good measure of the power density (efficiency) of the motor, and if you design for a particular displacement (as Porsche does), then it allows you to keep footprints smaller and weights down.

A better measure would be a comparison of hp/tq per motor dimension and weight.

Here is an example of that, two ford motors... On the left is a 4.6 and on the right is a 5.0

Those are valid metrics as well. Think about some of the markets where these cars sell. They actually tax displacement, the weight and size of the motor alone won't impact that. They have to engineer a total solution and hp/liter is part of that overall solution. No one metric (even weight to power) give you everything you need to design a good performance car.

Really curious and anxious to see how the Z/28 and the GT350 models stack up. Goes to show just how efficient the GM drivetrain is compared to the Fords.

The ls7 is making +400 whp for less the 2000 rpm.
The Voodoo is making +400 whp for more than 2500 rpm .
+700 rpm wider power band is nothing to write off , if you tell yourself different your just being a fanboi.

That doesn't change the fact that it means nothing for a car.

You could be making 342 hp/L ... but if its from a 750cc engine you're only making 257 hp. Meanwhile, even a lowly 39 hp/L engine can get you 400+ hp if you make it big enough. Which one will result in a faster car? The one with more power, right?

If you're thinking 'well, it depends on how much the engine weighs' I would agree. But doesn't that then defeat the logic of hp/L being an important engine metric? Making the one of actual importance hp/lb?

I can't think that Ford developed the Voodoo because of displacement taxes (which are downright idiotic). Odds are 80+% of the GT350's are going to be sold in North America. And there aren't going to be all that many sold here to begin with. So it would be an enormous investment to make a small number of cars (which I'm sure are going to be pretty pricey in foreign markets anyways) a little more affordable to a few customers. The bean counters at Ford are more responsible than that.

7.0L vs 5.2L , that little Ford engine is putting up some good numbers.

Well the LS7 redlines at 7000, and crosses 400 whp at 4800, so that is actually a 2200 rpm spread, the voodoo pulls over 400 whp from 5700 to 8200 redline, or 2500 rpm.

Power under the curve!
