the Z06 (2013) has the 427 ci (7 liter) with NA. the zr1 had the smaller 6.2 liter (ca.375 ci) with supercharger. why not put the 7 liter in, with the supercharger and determine once and for all the fastest road car. none of the porsches with their 6 cylinder power plants could presumably touch it in 0-60/0-100kms or 1/4 mile? would the 427 be uncontrollable with current technology if equipped with supercharger?

I'm sure GM has considered that possibility along with many others, but seems likely technical and business factors are not gonna make that concept a reality in a C7 package. Course there's always Lingenfelter for those who want to go in that direction.

I like your idea!

You have to be able to put that power down. You aren't likely going to beat the fastest AWD/Paddle shift cars in 0-60, and unlikely in 1/4 mile either but just throwing more hp at it.. Too ferocious off the line. Anything other than that though.....

They went with the 6.2 for boost because the smaller bores offer more meat between the cylinders, thus improving durability. With boost the 6.2 is large enough to make all the power they would want to in an OEM application.

Callaway has offered that package for several years now for the C6 Z06. I believe it had 652HP along with a three year warranty.

because they would like to confidently warrantee the engine to 100k miles.

This is true, GM tried putting the S/C on the LS7 and the motor literally melted.

Bingo.

FI engines are rarely limited by displacement, you have turbo 5.4 Mustangs and 3.0 Supras making 1000+, but until you put the power down, reliably, and especially coming out of slow corners, it means nothing.

Size doesn't make power in FI boost does

Look at 3.0L twin turbo Supra's making 800rwhp for evidence. Blowers are less efficient true, but NA motors and FI motors are completely different animals. The strength of the block and thickness of the cylinder walls are far more important to making big power safely - and providing a 5 year / 100k warranty

That's a lot of heat soak

If you are not running against a Porsche Cup Car a Vette driver has all of the advantage already. It is amazing how fast C5/C5/C7s can get around a corner and power out of it. P car drivers are constantly being embarrassed by them on road courses.

I do not you will ever find a Porsche driver embarrassed by a Corvette.

Daekwan06

I think you will find many that have been embarrassed. One of the worst feelings after spending upwards of $100K on a vehicle, is to have a first row seat to it being OUT performed by a cheaper stock vehicle. Its the exact same way a Corvette owner would feel, if a stock Mustang performed better than his Vette.

Anyways.. the reason why you wont see a supercharged 7.0L offered from GM is due to a few reasons:

1) How much is GM going to charge for it? $150K?
2) Who's going to actually buy it?
3) How many would actually sell?
4) Will the 5yr/100K warranty apply to it?
5) How much power can be realistically put the ground in a RWD?

Ricer math 101. Tomorrow I plan on buying a pinto and putting a 1000 hp engine in it. Do you think if I pull up next to a new Porsche , the owner will even look at me twice ? What I beat him , does that mean he will feel bad ? Lol c'mon guys. I hate the money argument because anything can be made to go fast. Even a Camry

If you are looking only at straight line acceleration numbers, the C6 frequently came out slowest in comparison tests with such cars as the Ferrari 458, McClaren MP12C, etc., but would hold its own or win in road course lap times.

I think you are fixating on the straight line stuff and not noticing what an excellent all-around platform that Corvette is giving us. Acceleration is a good thing, but not at the expense of everything else.

NineBall

Do you speak from experience? Ever purchased a $100K+ vehicle?

When I buy cars, I couldn't care less if someone with a cheaper car out performs mine. I still buy what I want. There is always someone faster. 9 times out of 10, I'd still rather own the nicer or more expensive car, given the choice.

This sums it up:

The question was about being outperformed on a racetrack fellas. See the original post below:

Clearly if you are buying an expensive car for social status perks only. Then yes the pricetag and the brand are going to be much more important than the performance. Any monkey with enough cash can afford to purchase status.
