Sounds like a Wankel to me....:leaving:
I do not think it's a flat plane engine, doesn't sound like it revs high enough. |

In my humble opinion a FPC is no advantage in toque or HP and may be a disadvantage in weight and balance. The Sound difference is just from the redesigned Hot V exhaust. If you read the info on the Cadillac 4V, 4 cam, 4.2L V8 where the V mounted twin turbos gives them the opportunity to design the exhaust pulses to be Even for each turbo, helping the turbo lag and even out the heat pluses. That will make the exhaust sound just like a FPC engine, from a normal V8 uneven pulses. Also the turbos will quiet the exhaust reducing muffler requirements and temperature. We will learn to love the sound. I want one. Jim |

I think the short clip we heard on C8R is much closer to the 488. |

Absolutely the worst sounding car in either GTLM or GTD. Sound like crap at any rpm range and especially when getting on the car coming out if a slow speed corner.

1 quart for 5k is not even close to being a concern. Although none of my cars have ever come close to that, even approaching 200k.

I believe ferraris flat plane crank is 3.9liters in forced induction form is what we could see from the hot vee derived 4.0 twin turbo cadillac form. i dont think we will see a flat plane crank twin turbo sized above 4.2 liters. |

Lest we forget the best one of them all? The mighty F136 4.5L V8 from the Ferrari 458 Italia. 110 HP/L in Speciale guise.

That's called a Shelby GT350 since Ford did it first. I am a little concerned about the move to the FPC because in the case of said Ford it was the least mod friendly Mustang to date.

Adding to your point, only two modern FPC V8’s have exceeded 4 liters of displacement. One is obviously the 5.2L Voodoo V8 in the GT350, and the other is a 4.6L V8 in the Porsche 918. According to ZERV, who the forum tends to trust, GM is making a 5.4L V8 and a 4.6L V8 for the C8, and one displacement is likely to have a naturally aspirated variant alongside its turbocharged setup. Unless GM plans on making an engine with the Bore:Stroke ratio of a Ducati Panigale, There’s no way that they’re making a 4.6L or 5.4L FPC V8. |

With the leaked audio clip C8.R sound in which the engine sounds smooth and deep. It can most-probably be result of Flat-Plane crank. First I thought it was due to implementation of Turbos, but turbos cannot make Corvette Cross-plane V8 sound like that nor can exhaust system. Yes I realize that it is not official but the audio clip of the C8.R sound make it sound more like European V8 and only deduction for it can be inclusion of flat-plane crank instead of cross-plane.
Audio Clip: https://sportscar365.com/industry/au...-turbo-engine/ Finally Chevrolet decides to drop in Flat-plane V8 in Corvette. Never thought they will drop it in so soon. |

Turbos controlling the exhaust pulse is one thing I am not sure of. First of all I don't think it is possible. Even if it possible there is no practical reason for Chevrolet to implement it.

Doesn't have to be FPC to sound very different from traditional V8. As mentioned above, could be significantly different header/exhaust configuration, could also be DOHC. Personally, I can't wait to see another 7000+ RPM DOHC motor in a Vette. I still think the original LT5 in the C4 ZR-1 is one of the best sounding Vette motors ever, and I love the high rpm power without the huge low end torque.

Very nice sound from the LT5. :thumbs:

Why does bhp/liter matter? Bhp/lb helps you go faster...
