Behavior Modification
Back in the May 2010 issue, I reached out to many of you through the Shop Talk column, asking for your thoughts on modifying our C5 Z06. I have to say the number of responses we received really caught me off guard. Over the years I've always known that we had many Corvette owners, however, most of you tend be a little more on the quiet side. I've said this before and I'll say it again; this is your magazine and if there's something you want to see, simply email me at chevyhi@sorc.com with your requests and we'll do our best to get moving on it. Thanks to those of you who wrote in, and here are a few of the responses for everyone to read. Survey says-thumbs up to modifying, and we're already on it.

Modify? Absolutely!
Let me tell you just one of my stories. The car in question was my '99 Corvette Coupe, equipped with the stock drivetrain (LS engine, four-speed auto, with 2.73:1 gears). Completely stock, I ran a 14.2 in the quarter-mile. Not one to be satisfied, I modified it with the following: dual-snorkel cold-air intake from West Coast Corvette, Bassani X-Pipe, Borla hi-flow mufflers, and a dyno tune performed by Tony's Corvette Shop in Gaithersburg, MD. On the next outing, the modifications resulted in a 13.0-second quarter-mile. That's 1.2 seconds quicker than stock!!!

The real surprise however was the added benefit of increased fuel economy. It was already a great highway cruiser before the mods, but after the mods, the car would consistently get 34 mpg on the highway, as long as you kept your foot out of it. Think about it, 34 mpg is Chevy Cobalt fuel economy.

I was so pleased and impressed with the mods on that car, I did the same to the vehicle that replaced it; my current ride is an '07 Corvette Z51 automatic coupe. I am completely convinced that adding quality parts and having a professional dyno tune is the way to go. It is very cost effective and the car can easily be brought back to stock specs. Keep up the great work, I love the magazine.

Forever Young
I'm a 60-year-old "gearhead" that is a tech by trade and a hot rodder by desire. My compassion for hi-performance vehicles is what has driven this old dog since being a puppy. Fast is good, while faster is better.

The Z06, while a fine piece of GM's greatness, still has room for tweaking here and there. I would say, YES, by all means modify the suspension to make the good, even better. I, myself, would be prone to not only make the underside work more efficiently, but to also feed the horses more oats. Compressed air comes to mind. A slight boost, with some remapping of the computer, could make this C5, great!

I'm not one to go absolutely nuts (although I have built some pretty wild machines in the past). But rather one to make several smaller modifications that can deliver greater performance while still maintaining dependability and a tremendous "grin-factor" when behind the wheel. I wouldn't do anything to the ride that couldn't be reversed, so to take the car back to OEM, at a later date. However, for today, I would let it ROCK-N-ROLL. Just be sure to have a cardboard box for the original parts that you take off. Then, remember where you store the box, just in case.

Make The General Proud
To modify is what makes us American, it's the core of our being. You reference The General and I think he would approve of autocross', a short shifter, added boost, exhaust, and intake system in your C5-oh yes, he would! The General and his buddy Uncle Sam love to see us make each and every car our own, by adding parts, taking away unsightly marker lights, chopping, cutting, and otherwise personalizing and improving on what they bring us. Think of it this way, all stock vehicles are a bare canvas, a challenge, as if The General is saying: "Here, take what I have started and improve it."

The question isn't to modify or not to modify, but how much and how far do you take it, my friend. Never doubt your inner child that wants to add 500 hp to everything. Never suppress the urge to make that new car even better, it's what makes each of us happy, and happiness is good. Be proud to be "that guy!"

Straight Line Beast
I drive an '02 Z06 and have installed a cold-air kit, headers with free-flow cats, 180-degree thermostat, and a dyno tune, all of which have gained me 60 additional rear-wheel horsepower and still get 28 mpg!

Although I don't autocross, I know there is an 11-second quarter-mile in the car with street radials; if I could better my 60-foot time. What a rush for a 61-year-old man. Do it-you won't regret it!

Stock? What?
I'm 66 and have five Corvettes in the garage, belong to the NCRS, and every darn one of my Corvettes is somewhat modified.

Like you stated, I have never owned a car that I "could" keep bone stock. Even the '61 VW I drove in college was slightly modified. If I remember correctly, 36 horsepower just did not get me up over the hills fast enough on the way home.

I say modify the Z06 the way you want to and enjoy the car. If you are anything like me, then you know half the fun is turning wrenches, so why not enjoy yourself.

Rooster Call
Sean Haggai
Usually, this late in the month my keyboard sounds like a machine gun-pecking away. It billows smoke like a steam locomotive and the plastic keys melt under the friction. However, recently with our second move, this time from the Placentia, California, office to our new digs here in Hipvine (Irvine, California), the brutal finger-pounding of the keyboards have slowed. Trust me, that's not a good thing either. While our month of March, which produces edit for the July issue was a bit longer for us, I still ended up asking the gods of time for more hours of daylight. I'll be honest and can speak for the CHP team when I say that we have been running ragged with callused minds. We've got a crazy event schedule in the works though, which means the once sought-after free Saturday is generally spent catching up on late edit and working on projects. No worries, we'll get it handled just as we always have.

Like I mentioned, we've got a crazy autocross-heavy event schedule with an upcoming first for Chevy High with our association with the Holley LS Fest. Even now, as this is being written, CHP is prepping the '72 Nova for an autocross event at the abandoned airstrip in El Toro, California. CHP will be participating in the Run To The Coast Experience. From there, we're off to the Goodguys autocross event on April 9-10 in Del Mar, California. We're not finished yet; we're then heading to the May 15-16, Goodguys event in Costa Mesa, California.

More recently though, the CHP team hit up the Super Chevy Show in Las Vegas. There, editor H and I played with the Z06 and Nova during the quarter-mile TNT session on Friday night and returned the following morning for the autocross portion. Aside from cliffhanging from the Nova's steering wheel, skimming across the bench seat, kicking the back end out, and plowing into the cones it was awesome. I was skeptical at first about this whole deal, but who knew autocrossing a 3,500-pound muscle car could be so much fun? By the end of my first run, I was so crossed up I didn't know which way was which. Luckily I missed stuffing the Nova's nose into the curbing. Other than some spare rubber which accumulated on the right rear quarter-panel, we left unscathed and smiling ear to ear. Cones beware!
