How significant is the FDs areodynamic advantage over a C5 Z06?

What is the difference in frontal area and C/D?

IE if I had the same lb/hp as my buddies z06, and we went from 50-150, how big an avantage would the FD have?

A mildly-modded FD will beat a Z06, from my experience, that's my opinion.

Weight-for-weight...I say you give an FD the same HP as a Corvette, Supra, anything, and it will waste them. Many others will agree I should think.

"600hp VS. 1000hp Supra" comparison, no? Something like that. >_>

 

Ummm... sorry but you don't have an areodynamic advantage. The C5 has LESS drag than the FD. It's a VERY areodynamic car. Sorry to burst your bubble!

Oh... the Z06 is at least equally fast in acceleration if not faster than a "mildly" modified FD.

 

^^ I'm with this guy!

John, how are your new rotors working out? I'm about to pull the trigger and order some. Thanks for doing the leg work on that BTW

 

Even if you have the hp advantage or same, they'll have more torque. Combine that with better aero than the FD and you're left staring at a pair of tail lights. I dont like it anymore than you do, but that's just the way it is.

But that's not to say a FD can't be better *driven*...if you catch my drift.

 

i beat a zo6 with roller rockers, exhaust, and intake... my mods were at the time, DP,MP,CB, intake, FMIC, PFC, and 12 pounds... i beat it pretty bad

 

I don't know for sure, but since when is a C5's aerodynamic Cd. less than .29? Because that's what the Rx-7's is. Not that the difference matters that much, I'm just sayin'....

 

FDs rule the world and everything else is just flailing around in its shadow LOL.

a ZO6

Hook your FD up with a full exhaust, intake, and then strip it bare. That's right, pull it all out, I'm talking about the stereo, carpet, AC, PS, etc.....Put some earplugs in and go kick that ZO6 in the

 

a quick google came up with the following figures (fwiw):
>conv .34 >hdtp .31 >cpe .29

 

The RX-7 may have a very small aerodynamics advantage...

As close as they are I doubt there would be much difference until 140 mph or so where the RX-7 will be at the start of 5th gear (bad) and the Vette will have the advantage with it's 6 speed. I would think the Vette's torque advantage would be countered by the RX-7's higher red line and the ability of turbos to work harder under load provided the cork is taken out of the stock restrictive RX-7 exhaust. Bottom line is that power to weight ratio and aerodynamics are not the only important factors. Also, what will happen in theory may not happen in practice.

 

That's pretty funny considering they have the same CD Sorry to burst your bubble!

 

Z06s only weigh something like 200-300lbs more than an FD. Not much to make a difference out of anyways. The Z06 is an amazing car, so it takes a little more than mild mods to beat 405hp. That's why many FD owners who are financially fortunate enough switch up to Z06s.

 

Yep the weight difference is about 300.

Z06s approx 3100

FD approx 2800

However w/ full exhaust, intake, PFC with a good tune (12psi), weight down to about 2600 (don't need to pull the carpet or the radio just some basic weight loss) and you'll kill a Z06. This car will have approx 340 flywheel and will be 500 pounds lighter.

Now you have the power to weight adv and a huge stopping and cornering advantage

There are a surprising # of FD owners who are financially able to own most anything under a 100k and to them a z06 would be a step down. IMO they just are not that fun to drive which is what a sports car is all about.

 

Don't forget about gearing. The z06 has very good gearing, much better than a standard vette or even an fd. That and instant torque. You'll prolly need 350+ to the wheels to beat one significantly.

 

Or you can just make 336-338 RWHP at 2800lbs with bolt-ons if you want to hang with a stock 405HP C5 Z06.

If you're competent at tuning (or get someone to tune it for you) then its not that much work. Of course that's just to trade blows with a stock car that's probably still under warranty. Once they start modding you've got to really turn up the heat on the FD to keep up.

 

Trevor,

Of the cars listed in your sig, which do you enjoy driving and why? Just curious.

Tim

 

Even though some of the vettes get down to as low as .29 cd, don't forget frontal area which is just as important. The FD has a very small frontal area.

with 400 rwhp, I destroy z06s from a roll no problem.

 

I should hope so you crazy bastard

 

Um... Dan Neil's article in yesterday's L.A.Times quotes weight of the 2006 Z06 at 3147 lbs, and horsepower at 505, NOT 405.

 

The c6 Z is a whole different animal.

I can't wait to see some on the track this coming year but my car is far from stock hehe

 

i thought the question asekd AERODYNAMIC advantage? everyone keeps talking about power..

maybe i cant read

 

I just got the stealth back on the road after a long hiatus while I was concentrating on the FD. The stealth is straight mean and rather uncomfortable (mostly because of the rather loud exhaust and JIC FLT-A2 coilovers). I think I went soft cruising around with the touring suspspension FD for so long. I don't know...just depends on if I want the decent size gun that doesn't hurt your shoulder or the elephant gun that packs such a big whallop that you come away sore from the experience.

And as far as the aero question goes I believe its already been answered. The C5 has no advantage over the FD once you factor in frontal area with Cd.

 

As far as the Aero question is concerned, I think it only starts to play an important role at high speads.

 

If you read the thread you'll see the question was answered and now we're just having some fun.

Answer is NO

 

Okay so what's the frontal area of the Z06 and the FD?
