Default Move from FE to ME presents new challenge to Corvette Racing

Sorry for the tangential subject matter here, but we have been talking FE vs ME relative to the ZR1... as I write this the C7R’s are doing great early into the 10 hr Petit LeMans, last race of the IMSA season. The 5.5 L front NA chevy pushrod engines running against much more sophisticated stuff and doing great. Hopefully taking home another championship. Next year begins a new era it appears for Corvette. Mid engine, unknown powerplant , but my guess is DOHC twin turbo, and Im afraid: many reliability issues. Oh how I hope Im wrong about that last sentence. But if Corvette can bring out this this totally new car, street and track, without nagging reliabilty and recall issues, it will be a first. I write this for anyone weighing the decision of getting a C7 ZR1 or waithing for an early C8.. just my 2cents.

If the new car is turbo, its a big loss. Every twin turbo car sounds like utter ****, muted, ridiculous. Its very sad the NA car is gone.

I dont know what it will be, but the ME testing at Nurburgiring didnt sound like an LT4 or 5 to me.. more like a Ford GT...

It did to me, although that wouldn't rule out it being a turbo. It's hard to get an idea of how loud the car is from a video. Definitely not the V6 sound of the Ford GT.

I’m no accustics expert for sure... you may be right but all I know is that the ME at Nurbugring sounds nothing like my LT5... no external baffles as needed on the ZR1 there either. Here’s another’s opinion:

You mean everyone doesn't know that the top engine for the C8 is a twin turbo? That's the worst kept secret ever

I'm not so sure we will see a C8 team in racing. The car hasn't even been released yet and Daytona is at the end of January. That leaves very little time to take an entirely new platform to racing at a world class level.

There is zero gain to push the C8 into racing before they are 150% ready and everything to lose. The C7 platform is tried and true and will be sold to customers through at least 2019. I believe, based on what little knowledge is out there right now about the C8, that it will be the C7 racing next year.

What I do expect to see, is an expansion of Corvette racing to Europe for a full schedule, and possibly Asia.

The C8 is almost a no win situation for Corvette racing IMO.. if the car is faster, BoP either reduces power, adds weight, reduces fuel capacity or slows refueling process or all of the above. If the car has reliability issues, they get no help from BoP... it will have reliability issues.....its a totally new car....although Ford won the the manufacturers title this year with their $$$$$$ carbon tub Multimatic built GT and Gnassi race tested (in Prototype class for several years prior to GTLM) twin turbo V6, the archaich 5.5 pushrod V8 FE alum frame Vette brought the Champinship home again for Magnussen and Garcia (decided yesterday at Petit LeMans)....Doug Fehan seemed to say the ME would race in 2020.. I’m not certain if the rules require them to run the same car they start the season with. They make exceptions to the rules. Ford ran the GT in IMSA before a single street csr was made. Corvettes have been using Dual Clutch direct shift gearboxes for several years now despite never offering one in a production car. Maybe we see the C8 race car mid season??? I doubt it though. I think either at Daytona 20 or 21.

Most of the difference in the sound of various 90 degree V-8s will come from a different firing order, or a different exhaust. Car manufacturers meet with muffler manufacturers to evaluate various samples, and among other things, choose the sound they think will appeal to their target market for a particular car.

I thought Corvette Racing had already announced that the C7R would continue to be raced through the 2019 season. Is it too early to talk about Petit LeMans results? Are their still people out there who haven't seen their recording yet and will get mad if we start discussing it?

Having watched the IMSA race live at laguna seca, the C7.R was easily the beast sounding race car there. I love the looks of the Ford GTLM car more, but the C7.R sound was ******* awesome.
If you put that v8 motor or even somehow fit a nascar motor in the new Ford GT it would be ******* epic.

They wind the snot out of that 5.5 L smallblock... it was a 7 L years back... then got cut back to 6 L. And then 5.5L.. and that engine is hp limited with air/fuel restrictors. The Chevy smallblock pushrod V8 isnt dead yet. .

GM had a test session after the Detroit race (I think) where they ran the C8R in cameo around the track. So there is a racecar version coming for sure. Pics of it are over in the C8 section.
