I decided to show off another photo of my Monterey Red C6 Corvette. It can be seen on the upper right. The photo is of the Corvette in front of Graeser Winery in Napa.

I used to be very competitive in the SCCA Solo2 Washington DC Championship series. I competed from 1995-2002 in a Neon ACR coupe, and after a bit of time living overseas, I competed from 2004-2005 in a C5 Corvette. My skills may have eroded over time, but next year I plan on doing a track day at Willow Springs so that I can properly explore the performance of my C6 Corvette. I estimate that on my current 320 treadwear Summer tires that I could do a lap time of 1:35.5 which is four seconds faster than Motortrend did with the original equipment run-flat tires. Switching tires will greatly improve on this. I estimate a lap time improvement of 3 seconds if I used 200 treadwear Bridgestone Potenza RE71RS tires. However, if I use 100 treadwear Goodyear Eagle F1 Supercar 3R tires then I estimate a lap time improvement of 6 seconds (these are streetable track and competition tires). This assumes that my skills are still there. To summarize my estimates are: current tires 1:35.5; Bridgestone RE71RS 1:32.5; Goodyear Supercar 3R tires 1:29.5. Unfortunately the Supercar 3R tires are somewhat expensive at $1600 per set, but they will be worth it on track day. I am retired, so I am not concerned with having far less treadwear. The semi slick tread is fine for California Summers, but I may keep the old tires around for winter rain.

"I have a 2007 C6 a6 and I did 0-200km/h in 14.5sec and top speed of 304km/h on octane 98"

I have the window sticker for our Corvette, originally it cost $58,715. $58,715 in 2007 is worth $89,680.79 today.

Using a 1/4 mile and ET calculator (https://robrobinette.com/et.htm) it appears that our slightly modified Corvette should do the 1/8 mile in 8.4 seconds and the 1/4 mile in 12.4 seconds at 116 mph. From that it seems likely that 0-60 mph is probably in about 4.0 seconds and 0-100 mph in about 9.1 seconds. I have not calculated a 0-130 mph or 0-150 mph yet. For the 1/4 mile calculation I used a vehicle weight of 3440 pounds with 358 wheel horsepower. The wheel horsepower is estimated based on the Magnaflow exhaust (8 whp) and a tune (12 whp) added to the typical wheel horsepower for 2006 to 2007 six speed automatic Corvettes (338 whp).

The original equipment run-flat tires gave little grip compared to modern performance tires. The run-flat tires were also 3 pounds heavier than non-run flat tires. 3 lbs. at each wheel is actually slightly significant. Modern summer tires can improve both the braking and skidpad figure significantly. Lap times with modern tires also would be quicker.

There has been much discussion about tires, here is the guide that I use: https://grassrootsmotorsports.com/articles/track-tire-buyers-guide/

Currently our Corvette has Sumitomo HTR Z5 tires and a beastly sounding cat-back Magnaflow exhaust with x-pipe. I estimate current WHP at 346 to 348. I estimate cornering grip on a 300 foot skidpad at 1.05 g. Sometime in the future, I plan to take the Corvette to a track preferably Willow Springs. I will probably use Hawk brake pads and Motul brake fluid. I plan to lower the current lap time at Willow Springs for the C6 Corvette. I will switch tires to extreme performance tires, probably Bridgestone Potenza RE-71 RS. The current lap time of 1:39.50 is ridiculously slow. I expect to drop that by at least seven to nine seconds. The Motortrend journalists who ran a 1:39.50 were not competition drivers. Superior driving skill should drop the time by at least two or three seconds. I believe that the RE-71 RS tires are worth at least 5 or 6 seconds over the O.E. run-flats. This will take me some time though. I think that with good driving, and the RE-71 RS tires that our 2007 Corvette will get a lap time at Big Willow of approximately 1:30.50 to 1:32.50. I think that with my current tires that 1:35.50 is possible. Modern summer performance tires are so much better than the O.E. runflats it is amazing how much grip is available. In any case, someone needs to beat that slow lap time in my opinion.

The most important bolt on for the C6 Corvette are tires. A set of extreme performance tires like the Bridgestone Potenza RE-71 RS in stock sizes should, with good alignment, give 1.15 g on the skid pad approximately according to my calculations. I plan on getting them when my current tires wear out. Other good bolt ons would be Hawk brake pads and Motul brake fluid. I already have a Magnaflow exhaust with X-pipe. I might add the FAST intake manifold and Hooker headers along with a tune, if I ever need more power. That would give the LS2 engine about 47 more wheel hp than currently. That should be good for 11.9 in the quarter at 120 mph according to my math calculation. Top speed should be 194 mph. Just bored and playing with numbers today.

"Not quite all of the bolt ons but many of them...headers/X-pipe, CAI, 3200 stall converter, FAST intake/ported throttle body, tuning, drag radials/skinnies etc. Car is a 2006 Corvette LS2 automatic with the typical bolt ons yet still retains it's stock 2.56 gears." https://ls1tech.com/forums/corvette-performance/1495493-new-best-my-bolt-ons-only-naturally-aspirated-c6-ls2-10-7-127-29mph.html

"10.78@127.29mph on a 1.51 sixty foot.

Eclipsed 100mph (100.55mph) in the 1/8th and 127mph (127.53mph) in the 1/4 for the first time ever and even a new best sixty foot of 1.50."

I finally posted a picture of our beautiful 2007 Corvette! The photo is from the city of Napa, California when visiting friends. The color is Monterey Red metallic. Interior is light cashmere. It has both the see through top (shown) and body color top. It is fully loaded with options including the 3LT and Z51 packages.

Here are the center of gravity heights of Corvettes: C1 is 19.8 inches, C2 is 16.5 inches, C3 is 17.0 inches, C4 is 15.0 inches, C5 is 17.5 inches, C6 is 17.5 inches, C7 is 17.5 inches, C8 is 18.5 inches. It took a long time for me to find sources for all of the Corvette generations. These CG heights are for base models.

The LS2 engine is SO DAMN GOOD that Mercedes stole the LS2 nameplate and used it for their FLAT-PLANE-CRANK AMG GT BLACK SERIES' ENGINE.

Also the LS7 is somewhat based on the LS2... the small-block GM family and the Mercedes V8 engine family (specifically the 6.2L and the 4.0L, respectively) both use a 92mm stroke

Corvette LS2 engine six speed automatic has roughly 340 rear wheel horsepower stock. Bolting on a high performance cat-back exhaust with X-pipe and headers add 28 horsepower, high performance intake manifold is worth another 20 horsepower, and a tune is good for another 12 horsepower. So with those bolt on modifications the rear wheel horsepower should be about 400 or thereabouts. A C6 LS3 six speed automatic has 370 rear wheel horsepower stock. A C7 Corvette has about 410 rear wheel horsepower stock. I believe that the 2009 Nissan GT-R has 430 wheel horsepower. The underrated new Supra has 388 rear wheel horsepower. Just some information I have gathered.

A six speed automatic C6 Corvette with full bolt on modifications can do 127 mph in the quarter mile: https://ls1tech.com/forums/corvette-performance/1495493-new-best-my-bolt-ons-only-naturally-aspirated-c6-ls2-10-7-127-29mph.html

C6 Corvettes are a bargain here in the U.S. at current prices. Easy to find examples with higher mileage for less than $25k. The engine and transmission are very durable with many examples with over 200k miles that are doing fine. Lots of aftermarket support as well. A few bolt on modifications and the LS2 will put out over 450 horsepower at the crank. With mods the top speed should reach 194 mph. New tires make the most difference though. Light weight, low center of gravity, and wide track width give great cornering grip.

http://www.dragtimes.com/Chevrolet-Corvette-Timeslip-20128.html an example of a bolt on C6 Corvette LS2. Here is another example with only headers and exhaust: http://www.dragtimes.com/Chevrolet-Corvette-Timeslip-23010.html

Magnaflow exhaust, X-pipe, Hooker Blackheart shorty headers, Fast LSX-R intake manifold, and a dyno tune would make roughly 392 rear wheel horsepower with six speed automatic and would be California emissions compliant.

Rear wheel horsepower for C6 six speed automatic/manual is 340/350. Drivetrain loss is 70/60 hp. Horsepower of LS2 at crank 410-411 stock. Cat-back exhaust is worth 8-12 hp, X-pipe is worth 3 hp, headers 15-25 hp, intake manifold 10-15 hp, dyno tune is worth 12 hp. Our 2007 Corvette has the Magnaflow exhaust with X-pipe. In California the emissions rules are strict, but there are still plenty of choices for bolt ons.

0-100 mph is 9.6 seconds: https://www.caranddriver.com/reviews/comparison-test/a15132293/2005-chevrolet-corvette-z51-vs-porsche-911-carrera-comparison-tests/
