Mid-Engine Corvette's Twin-Turbo LT7 V8 Fully Revealed!!!!!! - GM Inside News

https://twitter.com/ninonessuno/status/945683644634497026

Corroborating with pictures that surfaced on the internet last week, the next-generation Corvette will be receiving a new DOHC twin-turbo V8 that’s likely to birth GM’s next-generation V8 architecture. Displacement still remains a mystery, and will likely remain shrouded in secrecy until launch. However, there are alleged rumblings a 4.0-liter motor for racing purposes, along with perpetual rumors the Corvette will gain a 5.5-liter V8 pilfered from Corvette Racing.

Regardless, the image shows a longitudinally mounted V8 with turbos hanging low off each cylinder bank and plumbing for the turbos that snake around themselves from back to front as it runs from the rear, to the centrally mounted airbox. An earlier drawing had made the turbos seem like they were mounted at the car’s extreme rear, but this image shows they will, in fact, be mounted more mid-ship, closer to the cabin.

The picture appears to show similar thinking as we’ve seen in GM’s 3.0-liter twin-turbo V6 LGW engine used in the Cadillac CT6. The turbos are closely coupled and include water-to-air intercoolers and it looks like the heads will have the exhaust manifolds cast into them, which is also similar to what Ford has done with its 2.7-liter V6.

According to the original poster over at Corvette Forum, this will be the last leak for the foreseeable future, kicking off a fresh round of speculation and once again propelling GM to the top of the news cycle as we wind down the final days of 2017.

OMG, all I see is a warranty nightmare for service departments just like the LT5 was.
