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?

It would get you a heck of a car. I've been a big ZO6 fan for a while now but with prices already beyond my reach, a modded base model C-6 looks better and better.

Rich,

You are right that the article was on an '07 Z06 and the loss of RWHP on the dyno. I understand where BM was headed with the high MSRP for a C6 Z06, but, in his post he stated ..."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." In my opinion, this statement for a C5 Z06 is just not accurate. That is why I posted some facts on the C5 Z06 to give BM and anyone else a different side to this statement.

From your posts, clearly you have an LS1 vert, which by the way is an awesome car for the money. I own a '01 6 speed vert, so I agree with the ability to drop the top when the weather allows. I was not sure which year C5 you owned so I just looked up the last year of the C5s for comparison (2004). Base price on a vert was $50,835 and I would think that most verts were ordered with some creature comfort options that would have driven this up a few thousand. In fact, the MSRP on my '01 was $52,880. Base price on an '04 Z06 was $52,185, and there were not many options available on the Z06, they pretty much came fully equipped. So, in my opinion, if you bought your C5 vert new, you probably paid a little more for it than a Z06.

I am not sure what Stage I package you are talking about, but $4,000 will probably buy you a package that includes new exhaust (headers, cats, x pipe, mufflers), new CAI, maybe a new set of roller rockers, and a tune. I would think that this would give you an additional 50 to 70 horses. This would put you in the area of 395 to 420 hp, and in the range of the stock Z06 of 405 hp. If we started with a base 04 vert at $50,835, added some creature comfort factory options for an additional $2,500, and the $4,000 in performance options to get it into the range of the Z06 hp, you are now comparing the modified vert at $58K verses the Z06 at $52K.

Your analysis talked about hp and tq numbers, assuming that alone would make a modified vert as fast, or as quick as a stock Z06. There are a number of differences between an LS1 and a Z06 that makes the latter a stronger performance vehicle, but let me just talk about one very important area. The transmission gearing. The Z06 ratios are 1 - 2.97, 2 - 2.07, 3 - 1.43, 4 - 1.00, 5 - .84, 6 - .56, rev - 3.28. The LS1 6 speed ratios are 1 - 2.66, 2 - 1.78, 3 - 1.30, 4 - 1.00, 5 - .74, 6 - .50, rev 2.90. The A4 is 1 - 3.06, 2 - 1.63, D - 1.00, OD - .70, rev - 2.29.

The closer ratio transmission alone will pull much stronger and quicker through the gears than an LS1 6 speed or auto. So, if I did my calculations correctly (which at my age is not always the case) if you modified an '04 LS1 vert in the same hp range as the Z06, you would have about $6 grand more in your car than an '04 Z06 and you will probably not beat it at the drags, and you definitely will not beat it on a road course. But I do have to admit, your top goes down in good weather!

I am pulling your leg a little bit here, but my point is it is difficult to compare the two vehicles. I too, like the fact that I can drop the top on my '01 vert and go cruising. But, by no means do I think that my '01 can be in the same performance class as my Z06 for similar or less money. Just not going to happen.

Just a side note, I got my high speed license a few weeks ago at Pocono International raceway. There was a C6 Z06 in my group and I could stay with him in the in field road course, but when we got out to the straight that additional 100 horses became extremely apparent. This was not a comparison on a dyno, but a real life experience on the track. The C6 Z06 is a beast, but I also admit, it is more money than I want to spend. My collection is just fine without it!

Rich

Wow,That's some info Rich,I love to learn new stuff.First off Congrats on your High Speed License.Well I suppose all I can do now is go out and get a Zo6.

But anyways I'm big enough to say that with those figures you are right and I was misinformed

Just thought it was a low rwhp and tq # for being a 07 zo6.But for the price,[07 zo6]which is high in my book,I suppose in the right area and the right shop for the money you could only come in close to rwhp and tq with mods to a stock z06,c-5 or c-6.Thanks again for the info.But it is nice to take off the top.Believe when I say if someone gave my a z06 I'll take it.

BM,

Before I drove the C5 Z06, I pretty much had the same opinion as you did. All of my Corvettes prior to the Z06 have been convertibles. In fact, I used to refer to non-verts as 2 seater Impalas. Boy was I wrong.

A stock Z06 has much more seat of the pants power than a stock LS1. Now, I still love driving my '01 vert with the top down. But when I have a need for kick a$$ speed, it is definitely the Z06.

My 01 vert is already at my house in Ft. Myers, and the '69 vert and the Z06 probably will be shipped there in the next 2 to 4 weeks. When I move down permanently, hopefully July time frame, I would be more than glad to have you over and we can take a ride in each, since both are six speeds.
