ok, i will correct myself.
true, most people think that more horsepower = more speed. sure, the Viper has 700+ hp and the Griffith only has 569 hp. (you would say "what??!!) but the "equation" above is sometimes not true. why?? because the Griffith makes up for its lack of hp in other factors. mainly, the weight of the Griffith. i was surprised by the weight of the Griffith, around 2000 - 2100 lbs. compare it to the weight of the Viper. see the BIG difference??
I actually knew a Blackpool weighs much less than a Viper, I just couldn't remember how much power a Blackpool winds up with. A fellow here named Pupik used to have a killer GT site with all the car-stats when they're fully-modded at
www.formulanone.org . Now all his GT pages seemed to have vanished, so I couldn't remember how much power for a Blackpool. In any event, I'd vote for the Viper having better overall acceleration on a straight run/Test Course scenario, but I could certainly be wrong about that.
...but since they're fully modded, does that mean the racing-kit is installed? Is downforce maximized or minimized? Identical? And what about suspension and gearing? You've got both cars full-modded, does that mean with a racing transmission? Doesn't that introduce a whole nother set of variables that can make either car faster than the other so long as you tweak their gear settings?!?
next, which car has manuevers better?? my answer is the Lancer Evo VI. why again?? because of a certain upgrade exclusive for Lancer Evos IV - VI. find out what it is
I have no idea what it is...yaw control? What do you mean by "maneuvers better?" More control/ better grip? Less downtime between braking and throttle? Less understeer? Less sway-induced oversteer? Better drifting capabilities? All of the above? What if one person
desires a bit of oversteer but another loathes it?
...see what I mean; explain to us in
detail why a Lancer "handles better", and then you'll still have to address Puke, who seems to disagree with you here.
the Dodge Copperhead mentioned is the orange one
Okay, I'm voting for the orange Copperhead. True, it has less power than the Aston Martin DB7 coupe, but I still don't know what you mean by "performance", so let's break this down into specifics:
1. Raw power. Obviously, the Aston wins here but let's keep going.
2. Short-run acceleration: we're talking quarter-mile or 1 KM here. The Copperhead packs about 350 horses, the Aston packs about 530 horses. You might think the Aston would therefore win. I'm voting for the
Copperhead.
It weighs 1,557 pounds
less than the Aston and has a lower power-to-weight ratio. Since both cars are fully-modded I'll say that includes tranny tweaks, which further makes the Copperhead a winner here.
3. Long-run acceleration/top speed: Now we're going round the Test Course. Again, both cars are fully-modded which means you can play with downforce and suspension settings + tweak that transmission.
Overall, it could go either way...sorry to say I have no idea here. More power generally = a faster top-speed, weight doesn't factor quite as much. Aerodynamics do, though. Sorry, can't answer this one.
4. Handling: this means quite a few things so I'll narrow it down to
4a. control: The Copperhead wins. For me we're talking about grip-style cornering. Running towards a turn, braking, and getting back on the gas with minimal drama. We're talking about
getting lower lap times essentially. Which car is easier to drive? Which one do you have to wrestle like an alligator? Copperhead wins hands down.
4b. Understeer: the Aston loses here. I've driven DB7s before they really have 'iffy' braking characteristics (even with the race-kit) which means the Copperhead will get thru that corner
later than the DB7, and with less "waiting" before understeer goes away (if it shows up at all).
4c. Oversteer. Aston loses again. I got one word for ya here: Fishtails! You don't have to go to a seafood restaurant to eat some.
4d. Drifting/ sliding: Can't ignore this anymore, not with D2 being such a popular racing-style nowadays. I would choose the Aston as being
better here. Finally. You can get it sideways easier, maintain a drift, and possibly get better control from the DB7, while it's still on good tires. In the Copperhead, you'd have to "force" the drift; you'd probably have to be on crappier tires to get it to break traction in the first place.
5. Ability win a variety of GT2 races. The Copperhead has less power, but this also means it can enter more races in GT2, half of which are horsepower-limited. Also, its lighter weight and more control (as outlined in numbers 4a thru 4c) mean the Copperhead can also murder plenty of cars in GT2 that have much more power. Some really experienced players may even be able to win the GT All Stars in a 350-ish horsepower Copperhead, matter of fact, if they're
really good.
the final pair. yes, the Spoon Civic and the RX-7 Infini are both stock.
i will re-phrase my question: which car has better overall performance?
ok, i have corrected myself. i am very sorry, hope you will not get confused this time
Better overall performance where?
Okay, I'll stop side-stepping with questions.
I'll provide the scenario:
Autumn Ring
Even tho the Spoon is front-drive and the RX-7 rear-drive, Polyphony Digital's representation of understeer is probably at its lowest ebb in GT2. Arguably at it's lowest. This means that in this case, the Spoon (which should ordinarily suffer more understeer) gets the better deal around a track like Autumn Ring. It is several hundred pounds
lighter, less prone towards swishy, sloppy behavior a stock RX-7 displays, and around this track you'd have more control overall I would say. Plus, the Spoon has that delicious VTEC system and a huge area to deliver the revs from (I believe a 10,000 rpm redline? I'm forgetting).
...so my vote would go towards the Spoon...driving stock around Autumn Ring on normal tires that is. But then that seems a tad unfair because the Spoon is basically more of a racing car specially-modified for performance; wheras the RX-7 Infini is a sports car that was sold primarily for hip dudes and gals who want to enhance their sporty, devil-may-care image. Some RX-7s are bought by midlife crisis types--guys mostly who are hitting their 40s and all a sudden realize they're getting old!
...all I'm saying is the RX-7 Infini gets a bit of a raw deal here. It weighs more due to the extras it's carrying because it is a street car first...racing car 4th or 5th. To get it to perform adequately on the track you need to do extensive modifications on it...whereas the Spoon
already has these mods mostly performed.
I do plenty of testing on stock cars, but none on fully-maxed ones. I only have so much time ya know. Then again a fully-maxed GTS has just over 700 horses in GT2. The Blackpool? Man I'm forgetting now...I'm kinda thinking I'll pay a visit to Pupik's site...(comes back) which no longer features GT2 stats for some reason! 
I was thinking a fully-maxed Blackpool stocks less than 600 horses...which kinda makes me think a Viper GTS would win the test overall. Now I'm really confused. 
.
It's tough to say really which one handles "better"--it's more of a preference of whoever drives either one.
