I just got to listen to sound of the 5.2 Flat Plane Crank engine of the GT350 and R on Automobile.com. I cranked it up on my Bose speakers and went to the back of my house to hear how it sounds. Dayum...that thing sounded wicked. Then my brother yelled at me for making it so loud, then he asked kind of car was it. He asked if it was a Ferrari or Lambo. When I told him what kind of car it was he was like, "Why the hell would Ford make a car sound like that?" "Where's the rumble?" I just shrugged my shoulders. I told him it just doesn't have the muscle car sound anymore. Then he tells me, I hope your Camaro won't sound like that. I told him...HELL NO!!!!

Love the car, don't like how it sounds. But that's just me. What say you?

So you thought it sounded wicked...and he asked if it sounded like a Ferrari or Lamborghini. Yet he then says I hope your car doesn't sound like that. That doesn't make any sense.

Sorry but a Ferrari or Lamborghini FPC sound better than any Mustang or Camaro ever will.

I don't think you will find many people here that will agree with that. While exotics like the Ferrari and Lamborghini definitely sound good, it is a different class of sound to me. Much like a TTV6 and a 911 sound good but I wouldn't put them in the same class as a V8 either. IMO a cammed long tube header mountain motor V8 sounds better than any car on the planet.

As for the 5.2 in the GT350, I want to hear it going flat out through the gears...then I will pass judgement.

I have not heard the GT350, so no opinion there. I do feel that the sound of Ferrari's and Lambo's I have heard sounds like an angry v6.

I'm not sure what all the hype about the flat plane crank is....maybe Ford is sandbagging and it's far more impressive than the dyno graph shows. What I see though, is a engine that almost matches the 10 year old LS7. Hold off on the 5.2 vs 7.0 because that 5.2 as we know is a lot bigger than the 7.0.

Voodoo makes power by virtue of engine speed (inertia) whereas the LS7 uses displacement. I.e. Power is the rate that torque can be applied but the FPC engine needs the inertia of the vehicle for this and is why the curve is so poor at low rpm. It's power is a function of engine speed. LS7 high T, low rpm, Voodoo low T, high rpm

HP = (torque x RPM) / 5252

A light car with momentum will go like hell with the Voodoo. Knock it off its rpm and it will need time to recover. A LS7 uses pure grunt (displacement). So the Voodoo needs 3,500 rpm to match the LS7 torque at 1,000 rpm.

If you compare the engines in their intended rpm range, Voodoo has the power edge (4500 to 8200) whereas the LS7 has the torque edge (3500 to 7000)

The FPC also allows for better breathing up top and quicker accelerating. Not too mention being lighter. Despite the size of the 5.2L, its actually lighter than the LS7.

I didn't know Ford had released the weight of the Voodoo. How much does it weigh?

Actually the Voodoo only has the HP advantage above 6,500 rpms.

I HIGHLY doubt that. Proof?

C&D said according to Ford it is lighter than the Coyote...which is lighter than the LS7 or close to it from what I could find.

That's true at any given rpm but if you look at them in their individual intended operating ranges, the Voodoo makes more power, the LS7 more torque.

The LS7 operates 1,500 rpm lower so pick points 1,500 rpm apart and compare. Example: compare Voodoo at 5,500 to LS7 at 4,000 rpm. Voodoo makes more power, LS7 more torque. If Voodoo loses speed it will struggle

Love the graph you made!

[shaffe]

I think it sounds wicked.

as far as whats impressive its a 5.2L engine that makes more HP than a 7.0L engine. It makes more HP than the 2007 GT500 supercharged 5.4L It redlines at 8,250 RPM. I am not trying to know the LS7 at all, but like hotlap said it gets the job done in a different way. I think that is very impressive

Gotcha, I misread what you were implying.

Anyways, because I was curious I also graphed the LT1..

[hotlap]

Baylor. It would be interesting to see the LS7 and Voodoo staggered 1,500 rpm on the same plot.

You are a true track guy. What do you think about an engine that must maintain high rpm to perform?

As a street driven car, imagine driving around with the rpm over 5000 or it is sluggish. Tooling around at 2,500 rpm isn't going to get it done. Chevy warned that the Z/28 isn't a good daily driver. I think there is going to be buyers remorse with many early GT350 takers.
