article from Corvette fever

"Backyard Mechanic" · 05-17-2007, 08:41 PM

Did anyone see the article in the tech section of the July issue of corvette fever.Page 38.They took a 07 zo6 and did a chassis dyno on it and it pulled 400.9 rwhp/385 rwt.Bone stock,they did what they called a stage 1 upgrade on it and got 498.1rhp/471.7rwt in the end,My surprise was on the bone stock first dyno run they only got 400.9rwhp/385rwt.A lose of 105 hp.Talk about losing some power to the rear from the flywheel.So much for 505hp.I know you lose about 15 -20 % to the rear wheels,It cost 3,995$ for stage 1.No offense to anyone with a zo6,c-5 or c-6 but for the money you bought it for I guess you could spend less money on upgrades and got more hp and tq then a stock z06.Don't get me wrong I think they are great vette's but without the option to take off the top off or put it down,

I enjoy the Florida sunshine in my vette.I was just surprised by the article and lack of hp and tq.I know you z06 people hate me now,

but I will still wave at you.

Just trying to bring up some #.Thought it was interesting.

What is interesting to me is that for the 2008 models, the regular C6 will be bumped up to 450 horses at the crank and the Z06 will still remain at 505. Unless the C6's price is bumped up quite a bit or the Z06 dropped substantially, I think that narrowed performance margin may cut into the Z06 sales. For the price difference, the money could zing up the C6 SUBSTANTIALLY, easily surpassing the power of the Z. Hell, $20K would put one HECK of a lot of mods into a C6!

Didn't you guys see the article on the " SS CORVETTE" ? GM is moving to create a middle of the road CORVETTE, the "SS" version. I will talk about this more later, but this is a just a bunch of crap to up the sales of Corvettes .

Wasn't the Fixed Roof Coupe a GM plan to have a cheaper Corvette to put on the lots? I believe they caught flak about it and that model mutated into the Z06 to quell the uprising.

So either they forgot history, or they are following a similar flight plan here for another performance leap...

Rob, I had to go back and read that part of the article twice, a measly 400hp and even less tq. I think GM is inflating the stock HP to justify the cost of the new vettes. I would be pretty Pee-O'd if I bought a new one and it only dyno'd at 400hp.

Ya for the money you could spend on upgrades on a non z06,you could have more power and be able to see the sun.And the best part you spent less money on the non z06.Joe how was the track?Any photos?

Well we got out there but late so I decided not to run. I wish I had though, It looked like the Vettes were having a good time. I talked to a couple of the racers and can you believe that they have never heard of our forum !!! Anyway, I hope to get out there early next month and do some Racin'.

Do you need some CorvetteFlorida flyers to take with you? That way maybe they will remember to check in here when they get back home.

That's very weird. A guy from another site dynoed his '07 Z and it pulled 466 rwhp. I can't imagine such a huge difference in numbers. Differences in humidity, alt., dynos, etc., may account for some of it but that's crazy.

Just rechecked a post from the other site and there are a lot of C-6 Z's dynoing 450+ bone stock.

Maybe I'm off base here, but I thought the original topic concerned a 2007 C6 and Z06. Maybe this puts a different perspective on things. How much of a difference is the difference in price between the coupe and Z06, compared with the C6 and the C5.

Base price for a 2007 C6 Coupe is $44,250. Base price for a 2007 Z06 is $69,175. That means a difference of $24,925.

So, what would $24,925 of performance mods get you in a C6?
