I talked with our car expert here at work. He said the 10hp/cyl is a good rule-of-thumb... if the goal is solely performance based.
But with consumer cars (and AlGore CAFE nonsense)... part of the advantage with DI can be used to improve fuel economy. And with that as a part of the equation - you won't see a full 10hp/cyl increase.

Well hell Mike - what are we doing wasting our time looking to GM for the C7 answers we seek . . If we had known you have an 'expert' at work, we could just tune out GM Detroit and Bowling Green completely.

Let's hit the middle and say 5hp per cyl. That would still be a gain of 40hp just from DI. So 436 plus 40 brings you to 476. The question is would GM want to bring it to 500hp? You would think they could do this if they wanted to. But at 500hp you set the bar high for the Z models. A Z06 type of car would need to push 600hp to justify the price, and if a ZR-1 type is made now it would need to be at or over 700hp. At the end of the day I think they will have the LT-1 hit 500hp for the marketing behind it and so like the C6 did when the base engine matched the C5 Z06 (400HP on Base 2005 C6, 405 of C5 Z06).

I would be super pumped if this thing ended up cranking out close to 500 hp in base form... Good god.
I hope you're right. 450 hp would definitely be a pretty epic disappointment for this car.

We will have the ultimate wheels for the C7 as well. One Piece 100% carbon fiber wheels by Carbon Revolution. They shed 65lbs on the ZR1.
Currently, only 8.5"X19 and 12"X19" will be available. Orders being taken for May delivery.
On our 2817lb Z06, we will drop 52lbs with the first set ever made for the Corvette.
We'll obviously see how these fit our C7.

Say what!!!! 14g My Viper six spoke are lighter and only cost $2500. They can't be 100% carbon. How is it that a carbon wheel weight more then aluminum wheel?

I think you're reading that wrong. I don't of many of any wheel that size that weight 15-17 pounds. That's ridiculous.
, might sound a lot for you, but for loaded enthusiasts it's a bargain.

Warranty = Lifetime structural and materials and 2 year finish.
DOT – does not have an approval it is a very old specification that has no teeth. In the U.S. the SAE 2530 test is the wheel standard that all the OEM’s adhere to and we have passed these test as well we added 30% to these loads and passed again.
In Europe they have the TUV which are more difficult test to pass than the U.S. the TUV test for aftermarket we passed and added 30% again and passed.
The last most difficult testing protocol is the European OEM wheel test called the AKR and we passed this test added 30% and passed again I will attached to this email our test results with the PASS stamp.
8 to 10 week delivery. 19" only. 100% Carbon Fiber Wheels. Carbon Fiber Material Explained.
Carbon Fiber Reinforced Plastic (CFRP) is a super strong and lightweight material that is gaining increasing favour with engineers. In tension, for a given weight of material it’s at least 3 times stronger and stiffer than steel, aluminum or titanium. Carbon fibers are basically very thin strands of carbon, much thinner even than a human hair. All the individual fibers are bunched together in what is called carbon fiber tow.
Each tow can have between 2,000 and 50,000 individual fibers in the bunch. This tow material is then woven or stitched together to create different carbon fiber cloth materials. The tow can also be used directly to manufacture certain parts. The step between these dry tow and fabric materials and a finished solid material is the introduction and curing of a resin to turn the carbon fiber into a CFRP.
You will not have to visualize these on a Corvette. Our ULZ700 will sport these wheels in May and be at the Katech Autobahn for viewing and testing by Johnnie O'Connell. Our Z06 is 2817lbs (no fuel) now, and will be 2765lbs with these wheels and Pilot SCs. 660 HP.
Carbon Revolution’s wheels are also tested for lateral impact performance. In this test, a calibrated striker hits the wheel on the spoke face, mimicking how a sliding vehicle would impact a curb. All Carbon Revolution parts exceed the loading requirements of this widely accepted test.

The biggest draw back, to me, is that these won't be available in the stock size (let alone the stock height) of the Z51. That's kind of a big deal to me.
