ZO6 vs. F430 dyno figures.

i owned a 2006 z06 from 10/5 to 4/6, drove 5000 miles and 4 track days and i dont believe it will turn faster laps, except on the smoothest of tracks. the recent C&D track comparo found the Z lapped slower, and ID's the main fault of the car:

it handles bumps in corners very badly, is upset badly and I have direct experience with this; it's f.g scary, whether it's the mid corner bump in McClure tunnel on PCH, or the one in turn 6 at big Willow i am way slower in the Z. strad.s are the best at this, and i hear 430's do it well also. whether it's worth the $$$ to have this finer handling is up to the purchaser.

the Z is still a great achievement and a steal at 65, i enjoyed mine alot.

 

Yeah I own a Z06 and I have driven a couple F430s and the 430 is definately more fun and involving to drive but to dismiss the Z06 outright is a mistake because it is a blast to drive as well. It's alot better than a Porsche TT or an Aston. The F430 is a hard experience to duplicate.

 

Well, the Z06 is faster on the nurburgring, and that's a pretty bumpy track! In the hands of a pro driver the Z is faster. The test you refer to had the Z on run flats and the 430 on r-comps . . . hardly fair! But, I will concede that the 430 is easier to drive for us mortals, but a pro driver will definately turn faster laps in the Z.

 

Just keep telling yourself that.

Do you have a more reliable source that can refute the official times posted on that site? If not, your post was useless.

 

Tell you what I notice from that site. Every time the same car is tested by someone other than Sport Auto it goes nearly 10 seconds faster. That means that if Sport Auto tests a Z06 it should run in the 7:50's.

 

Owning a 430 Spider, I was interested in an answer to the original post. I guess there isn't any 430 dyno data, at least any that will be disclosed.

 

Here is your answer: http://www.ferrarichat.com/forum/showpost.php?p=136006696&postcount=9
Maybe 10 or so HP below Z06 peak numbers. However, the Z06 has more area under the curve. The 430 has better gearing.

 

Hey Watt, nice to see you posting. I ran my 430 on a Mustang Dyno which was on site at an Autocross my son participated in. The result was rather disapointing. It showed 363 HP at the RW. This was a portable setup and had no fans. The weather was rainy with 100 percent humidity and temps in the low 60's F. Car ran on 91 octane. Don't recall the torque figure and the dyno sheet is in the car - and not at hand right now.

I am told that Mustang Dynos tend to produce lower results than others such as Dynopac. The car was fueled with 91 octane.

The owner mentioned that he had done another 430 and it showed 385 HP on the same machine but was running 94 octane. This suggests that Watt's expert guess is close to the mark. Another data point is when compared to my GT3 on the track, the F 430 clearly out accelerates the GT3 in spite of being about 500 lbs heavier. The GT3 is known to make about 360 RW HP based on dozens of published results. This makes me suspicious of the result I got and question the 380 figure.

I tend to distrust chassis dynos for anything but A-B comparisons since I have seen pretty strange results every time I do a run. My 2002 GT2 showed 517 RW HP .. which I doubt was true.

 

bob in my experiences with dynopak, dynojet and mustang, it's very hard to compare mustang with the others, and the numbers always come in quite low. Other tuning communities have used a 1.2 correction to calculate crank hp when using the mustang fwiw.

I too owned a gt3; they are truly beasts and are underrated from the factory.

 

This is a very funny thread. First the vette is faster on track. Remember though that this is the fastest vette ever built and it is as fast or a little faster then Ferraris cheapest and most common model...

Take a 430 CS when it comes and compare it to the Z06 and the vette will be a very slow car in comparison.

Also a vette is only a vette no matter what, but a Ferrari is an excotic, a very rare car so comparing them is imo really stupid. Still the Z06 is a fantastic car but would i change for my 360 and get lower yearly costs ? No f*****g way !!!

 

Wait until the Blue Devil comes out. 650hp at 2900Lbs. It will faster than any Ferrari made for road use. Then it will be even harder to say,"vette is only a vette no matter what".

 

As many have pointed out, this thread is silly. Think of it this way, do you wear a Timex or a Rolex? The Timex keeps good time, has lots of features and cost less than a full tank of gas in a 430. A Rolex (or Patek, Breguet, IWC, Jaeger Lecoultre etc.) costs thousands and doesn't keep time as accurately as a Timex, Casio etc. Why then is Rolex (et al) still in business?

The answer is that for some people a Breguet (to name one) is more desirable than the Timex despite the fact that it is less accurate.

Some buy high end mechanical watches to impress others. Some buy Ferraris for the same reason. Others buy high end watches because the appreciate the ingenious mechanical complexity and artistry that is implicit in the design and construction. Some people buy Ferraris for the same reason.

The Corvette Z06 is a great buy. So is the Timex. To the right person, a $100,000 Pateck is also a great buy. They both have their place but we don't compare them.

Drive train loss is very low on those cars. Like the NSX, the GT3 has very low drivetrain loss - around 7% or so.

 

Two awsome cars...very different personalities....I know first hand.

 

Amen, for the $$ it is hard to beat.

 

Don't agree with that; other 911s show 15% or so drivetrain loss, or reason to think that the GT3 magically is better.

It's all academic anyway, what matters is rwhp.

 

Why? Because you say we don't compare them? Great reason. I've owned both and I love to compare and contrast them. It's not like Ferrari is so good they are above comparisons.

 

Drive train loss is, in general, the same. When people quote cars having high or low drivetrain loss, it's really an overrated/underrated engine from the factory. Most, if not all, Porsches are underrated from the factory. Same for the new Z06 and new Viper (both putting out about 550hp instead of 505 or 510).

 

Actually, alot of these dynojets are corrected way too high. If you put the engines on an engine dyno, they make right about the rated power. According to Katech, the new Z06 makes it's rated power.

 

true!
even of the oem's were to underate they sure wouldnt do it by 40-45hp!?

Take a look at this. It seems that Ferrari is a little faster than the Vette on this track!
