Actually, Mercury Marine built it. Lotus designed it. But at that time, Lotus was wholly owned by GM.

Then be specific. We talk about Corvettes a lot in here if you haven't noticed, easy to make that jump. And Chevrolet is GM. I assume now you were talking about the Caddy Northstar engines, but whatever.

Oh yeah, that's what I meant

I don't buy manufacturer's posted times anyway, didn't Chevy get caught cheating the timers with the Z28 a few years back, Dodge claiming 9.65s for the Demon.

You’re confused by M6G propaganda

While I agree that the 9.65 Demon claim by Dodge is false, Chevy is typically pretty good on their performance claims, in fact they often undersell the performance of the car. Look at the Camaro SS for example, they say 12.3 in the 1/4 which is EASILY beaten with real cars that are sold off the lot.

Then contrast that with what Ford did to promote the Mustang GT A10 PP. They had that publicity stunt done with the resulting claim of 11.8sec in the 1/4, yet I have been watching the actual cars that come off the lot, and that claim has proven false. They basically had somebody else write their ad copy with that stunt.

Bottom line, ANY 'published' performance claim could be questioned, just go out and see what the actual cars that you can buy off the lot do if you want to know the truth.

Would emissions and reliability requirements be met at that output? Only exotic NA engines have higher specific output than the Voodoo.

That said, I hope they do it: 600+ hp FPC 5.5 liter C8 Z06.

With the C7 Z06 putting out 650 HP its logical that they wouldn’t drop back below 600 HP for the C8. Whatever the power rating will be, the expectation should be that the C8 Z06 will outperform the C7 ZR1.

I also prefer NA over FI. I owned a 13 ZL1 and didn’t care for the weight and inconsistencies from heat soak.

stunts and asterisk * models.

Ford took until the ZL1’s fourth model year in roll out the GT500 ...including a $94k GT500* called the CFTP. They brought trailers filled with cars to VIR and then went home. Disappointing. Oh well

Ford Not Interested In Chasing Lap Times With Shelby GT500

Chevrolet isn't shy about such things

Ford’s new 2020 Mustang Shelby GT500 should be one fast machine. Thus far we only have a few vague stats from the automaker to gauge exactly how fast it is, and those estimates only account for straight-line speed. In its GT500 press release, however, Ford was keen to tell us about the car’s suspension tuning, aerodynamic enhancements, and massive brakes. Clearly, this Mustang is designed to be more than a one-trick pony, but according to Motor Authority, Ford isn’t interested in benchmarking the GT500 with official lap times.

Speaking to Motor Authority at the 2019 Detroit Auto Show, Ford Performance Chief Engineer Carl Widmann allegedly said there were “no plans” to go lapping with the GT500, either for benchmark times or records. Reportedly he went on to say Ford hadn’t published such numbers in the past, but that’s not entirely accurate. Almost a year ago to the day there was a bit of excitement over Ford racing driver Billy Johnson setting a lap record at Virginia International Raceway in a Ford GT

It could be argued that it wasn’t an official Ford endeavor, having occurred after Car & Driver’s Lightning Lap testing at the track, but the time was certainly shared by the Blue Oval's PR crew. And then things went strangely quiet when Chevrolet beat that record days later with its Corvette ZR1. That was back when Jamal Hameedi was the chief at Ford Performance, and curiously, he said almost the exact same thing as Widmann.

Chevrolet, on the other hand, has a Camaro ZL1 1LE that can lap the Nürburgring in just 7 minutes 16.4 seconds, and it let the entire world know about it. Ford never officially sent the Shelby GT350 to the Green Hell, but unofficial times had the 526-horsepower (392-kilowatt) Mustang clocking a 7:32 lap. With the GT500 set to make over 700 hp (522 kW) while utilizing segment-leading brakes and aero tweaks up the wazoo, it feels like a tremendous cop-out if Ford doesn’t dip its foot into the pool on this one.

In the report, Widmann did suggest that Ford would send a GT500 to Car and Driver’s next Lightning Lap showdown at VIR, so there could potentally be at least some closure on the big Shelby’s track prowess. But building something as awesome as the GT500 then stepping away from direct competition seems a bit weak to us. Come on Ford, give the people what they want – a proper Mustang-versus-Camaro showdown.

What stunt with 11:80s, you understand several reviews have gotten 12:00s and 11s right? Its only a stunt because the Camaro can't match it. If C&D can get 12:00s out of a 18 GT on an unprepped track do you really think it is far fetched that it could run an 11:80s on a preppered surface with a great driver? Look at the mph the car traps.
------------------------------------------------------------------------------------

You want to know whats a stunt, Chevy taking a supposed stock car to a track thousands of miles away, installing roll bars, endless electronics to review every foot of data, having an entire Chevy support team there supposedly not making any modifications to the car, going through endless sets of tires (tire manufacturer support either on site or on the telephone), having a paid pro-driver run the car to an inch of his/car's life in order to publish a time that will never ever be duplicated without a massive budget to match all above. This is a stunt! This vs what you call is a stunt, a GT running 11:80s at the track. Comical!

They are afraid the 94k CFTP will perform poorly. It may not even beat a 350R. Already rumors about the 350 being faster than the base 500 on a track.

So you're saying it's not only a matter of adding +200 HP to the GT350R?

I'm disillusioned.
