C7 Corvette Updates/Info

The (visible) aero is actually more aggressive than on the race car, same for those front corner intakes.

It makes sense, though, the C7R makes only about 500 hp and weighs less than 2600 lbs (2745 lbs w/driver and full gas tank), and its most important tracks have very long straightaways. This potential ZR1 is likely going to have at least 650 hp, weigh around 3500 lbs, and be driven on club tracks more than Daytona, Sebring and Le Mans.

That swirl paint isn't hiding anything...

It is kinda awesome though.

Sorta like "see, it's a test mule.".

Detuned for reliability? WEC/ IMSA/ SCCA regulations?

Regulations, mainly around inlet size. AFAIK anyway.

Yep. The race engine is also 5.5 liters instead of 6.2.

same block, but de-stroked?

To not answer your question, just found out that Corvette Racing's engine builder makes a 7 liter LT1 kit: http://katechengines.com/performance...s/c7-corvette/

It uses an updated version of the C6.R V-8, not something based on the LT4. Why forsake the Z06’s mighty, supercharged LT4 small-block V-8 for the C6.R engine, especially given the fact that the C7.R is directly developed off the Z06? Blame the rules, according to Fehan. “We can’t use the supercharger or the variable valve timing. Add the fact we’d start life with 6.2 liters in an all-new architecture, [with a] new block and new cylinder heads, and then have to de-bore and de-stroke to 5.5 liters to meet the rules. To go through that process on a brand-new engine with the time and expense to determine durability and reliability didn’t make any economic sense when we already had a proven 5.5-liter done.” The one big change made to this year’s version of the V-8? Direct fuel injection, last used in the 2009 car, has returned. It allows for more precise throttle control and about a three percent gain in fuel economy, enough to potentially eliminate one pit stop in a 24-hour race.

MOAR codes, then?

DOHC engine for Vette in 2017?

New LT engine? Where does it fall in the heirarchy? Will it be a "premium offering?" Lots of questions.
