FI on a ZO6 sounds exciting.

Any word on AWD or DCT being available as OPTIONS for any year or version of the C7 ?????

Thanks.

 

HELLO!!!!

You have my attention. Not a fan of the design, but a big fan of the weight. How strong are these and do you have an idea on cost?

 

You and Hennessey And your claim regarding DI, how exactly you know what the power is before adding up the gains from DI? Just curious about it...

 

Maybe in "Bizarro World"...

 

Fixed it .....................

 

Just assuming that if the LS3 with NPP is at 436 HP, and DI averages 10/cyl. on the same displacement motors, according to GM, just do the math.

 

The LT1 is going to be a baaaaaaaad boy.

Compared to the LS3 you've got a better flowing IM, smarter computer with higher capabilities(it's got a humidity sensor, any thoughts Jim?), 11.5:1 compression, higher flowing heads, LS7 style headers. People forget that the Z51 exhaust is larger than the LS3 exhaust as well.

Even it doesn't hit the 505hp of the LS7, its going to be closer to that number than the hp of the LS3.

 

Here's a good closeup of the engine. Its going to be a beast once the tuners get ahold of it.

I am leaning more and more toward 510 HP. I believe the LT1 will match the LS7 motor easily, or at least has that potential.

Let's look at the dry sump version of the LS3 found on the GS. Tested at 414 RWHP by GMHTP Magazine dynoed 3 times in a row within 1 RWHP. Most LS7s average 448 RWHP to 450 RWHP. I have owned two, and both dynoed 448 at the wheels. I have seen maybe 30 different dynos hit numbers close to 448 on the DynoJet. 34 RWHP now separates the LS7 from the LS3 in the Grand Sport according to GM High Tech and Performance Mag.

Forget about correction factors for the moment. 448 RWHP would represent 57 HP lost to DLL average on the LS7. The LS3 Grand Sport making 414 RWHP should be around 471 HP if the motor was recertified by SAE using the same loss factor to DLL.

Now GM's claim of 10HP/cyl for equal displacement. You see the potential for huge numbers. Even 7HP/cyl is 56 more hp than the LS3.

I can see some LT1s making close or above LS7 numbers. As I said, I have no hard information on the LT1. I'm waiting for numbers like everyone else. If they come in at 450 HP, that would be a huge disappointment in my opinion, and would not advance the direct injection platform at all. Even the compression ratio would bump 12 HP to the LS3, leaving zero hp gain for DI vs. Port Injection?

I do not want to be argumentative but would really prefer for someone to actually dyno the engine and then the car to make sure this is really the case. The engine has a pretty high compression according to GM, it should be more hp than GM claims. Maybe there is something else going on here?

 

$15,000 set

 

Any sentence that begins with the words "I don't want to be argumentative but" - really means "I want to argue"

 

I do not want to be argumentative but

 

I thought the C7 was using the GPEC II computer???

 

Correct: $14,990 set

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.





How many aluminum wheels could survive this at 60mph?

 

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.

 

A few years ago, this was the only way you could purchase these wheels. Buy a $650,000 Ultimate Aero:

Halltech has been involved in the development of these wheels for the Corvette. 3 years ago they had no interest. Today it is a reality.

 

Now, what are the chances for two super car builders to have the same last name and then name their companies after themselves?

At less than 2800 lbs and packing all this hp, you have something that C7 should have been. This is outright impressive

 

My take as well.
