Porsche Twin Turbo vs C5
 

I just had the opportunity to drive a new Porsche Twin Turbo. Now you have to understand, I am a Chevy guy from day one, but I was impressed with this car. In fact, it would probably give my Vette a run depending on the driver. However, even with all wheel drive, I don't like rear engine cars! :smash: And the price of one of the Porshe's is equal to 2 plus Vettes!

From what I have heard, the TT Porsche is quicker than the C5. But for more than twice the price, you can buy a lot of mods to make the C5 a lot faster.

Aw....I must idmit it was a Porche Turbo (great car anyway) who did "beat" me a late night for a few weeks ago, thats the major reason why I'm installing SC in January.
Silly? yeah mabye it is....but It hurt when a Porsche do this..... :mad

No flaming :boxing I love and have a Vette and have had access to a 3.6 TT and have driven a few modded Z06's and let me say that it you put equal drivers in the cars a super modded Z06 would not do to well IMHO. But let's all be honest - who cares because I don't have 120ish laying around :smash: :boxing :boxing

Re: Porsche Twin Turbo vs C5 (MilYellow02)
 

I believe it was Car & Driver who recently had a shootout where the Z06 beat the TT Porsche. I'm pretty sure they had skilled/equal drivers in both cars. ;) :cheers: :cool:

Re: Porsche Twin Turbo vs C5 (l2vette)
 

I live in Belmont, and actually played with a new 911 Turbo on southbound 280 in the Woodside area. It still didn't have plates on it, so it must have been fairly new. He wouldn't commit to an all out bonzai run, so either he was still breaking it in, or he was chicken. However, he did jump on it with me tucked in behind him to about 110mph, and he definitely was pulling me. Now I just have a 1999 coupe with six speed that is stock, but I was impressed! Of course, for that kind of money, a 911 Turbo should be able to do something!!

Re: Porsche Twin Turbo vs C5 (MilYellow02)
 

I had the opportunity to run our stock Z06 against a new Porsche TT last August on the way home from Monterey. From 70 to 145, it was a dead heat; I probably could have done a little better by starting in 3rd (instead of 4th) at 70.... Oh well, for $70 large difference, I'll take the Z06.

Re: Porsche Twin Turbo vs C5 (l2vette)
 

Man you guys are so lucky...I haven't ran into 911 Turbo yet, only regular one.

And I think you guys already know the outcome for those non-turbo Porsche :D

Re: Porsche Twin Turbo vs C5 (steve hummel)
 

Let me start over :seeya A broken-in 3.6 against a modded broken-in Z06 and a driver with balls like us Vette owners yield in :chevy defeat. As far the test in the magazine. :bs I bet there are a few forum gurus that would agree with me that the Mags, you know which ones, just don't seem to have the numbers that we all deserve and sometimes believe. I know all you people love me, and I would kill my ex-mother-in-law to own a Z06 or to Super-Mod my Coupe, but I am right. Once again, no flaming :cheers: :cheers: :seeya

Re: Porsche Twin Turbo vs C5 (MilYellow02)
 

So we're supposed to trust your seat-of-the pants meter that the 911TT is a quicker car than the Z06??

Car and Driver hooked up test equipment on the same day with the same driver** to both the Z06 and the 911TT and the Z06 was quicker (from 30 MPH on). I think that is a little bit more objective than your seat-of-the pants meter. Again, no flame intended. :chevy :chevy :flag

**Correction below - Porsche sent their best driver and Chevy sent their best driver

Cliff, what do you think about some magazine facts - Keep in mind I am a Vette owner - all I have owned in years - and by the way love your bad ride. I am not a Porsche fan but would love to own one, but think the magz don't tell us poopie other that MSRP and they even Clinton that up. Some of the things that the mags screw up is probably minimal - yea right.
M/T same car, somewhat same conditions, same driver, same equipment = dry weight - 405 Z06 - 3216 pounds somewhere in the 4 sec. range
M/T same story weight 3100 pounds, feul 20+ mpg say GM claims 3.9 but they cannot get it to go that fast.
C&D TT weight 3395 3.9 0-60 12.4 1/4
C&D TT weight 3491 3.9 0-60 12.3 1/4 all with same driver. My point is :lol: :lol: These magazines dont mean squat, I mean my
96 Mitsu 3000 VR4 went 0-60 in 4.5 seconds in every magazine for a little less than 2 years and weighed over 3500 pounds via 4WD AWS etc with 320 HP and 300 lbs of torque - I can only imagine what the real dyno numbers would be probably 299/281 or less. JMHO about numbers in Magz regardless of where, with who, temp and so forth. I will try and check with other members and hopefully I am wrong because I want the Vette to stomp 120 thousand dollar stuff. :cheers: :seeya

Re: Porsche Twin Turbo vs C5 (MilYellow02)
 

I've also had the opportunity to drive both. My impression of the Porsche was Z06 performance with Mercedes engineering and quality. Both the Z06 and TT are excellent cars.

Re: Porsche Twin Turbo vs C5 (l2vette)
 

I had a 993 C4 for my wife a few years ago,didnt like it at all,even though its kinda of fast.Twin t would likly beat our C5 (not to metion the gt-2) but well
I would choose the vette any day over it . :smash:

Re: Porsche Twin Turbo vs C5 (Viprklr)
 

Right you are! Here're some notes from the article:

"Porsche sent three-time LaManas and long-time Porsche driver Hurley Haywood. Chevy sent hard-charging John Heinricy, GM North America's director of vehicle dynamics and a successful production car racer.

The common thinking at the staging area was that the Porsche's all-wheel-drive system would help it overcome its less-advantageous power-to-weight ratio. The Porsche's twin-turbocharged flat-six thumps out 10 more horses than Chevy's newly fortified405 HP V-8, but the Chevy has the substantial advantage of being 375 pounds lighter.
The Porsche squirted off the line quicker, as we figured it would, to 30 mph. But when the needle touched 60, the svelte vette opened up a 0.1-second gap that would only widen as acceleration continued. Heinricy is also well practiced in production Corvettes (some of Haywood's time has been spent in Prsche race cars) that he snicked off clutchless upshifts as if in a finger-shifting Formula 1 racer.
If we thought the Porsche would have the edge in straight-line acceleration, we weren't sure what would happen on the road courseThe best Corvette Z06 we've tested outperformed the 911 turbo in the skidpad (0.98g versus 0.93 for the 911) and in braking tests, stopping from 70 mph in 152 feet, 11 feet shorte than the Porsche can manage. But again, we thought the four-wheel-drive Porsche would squirt out of corners quicker. Any advantage the Porsche's driveline provides wasn't enough, however, as the Vette pulled higher grip in almost every corner and finished the road-course portion sooner by 1.9 seconds.......But as the speeds increased, the Vette's lower drag coefficient (0.29 versus 0.31) gave it another edge, and it finished the full course a slimmest-of-slim 0.7 second sooner."

Well, there you have it - the best Porsche driver vs the best Chevy driver and the Z06 comes out on top, despite the whopping $66,500 price difference!

Porsche, it's back to the drawing board time!

Re: Porsche Twin Turbo vs C5 (Dave68)
 

Thanks Dave68 for actually quoting the article. :cheers: I'll agree that both are great cars and I'd love to have either one, but when it comes to best performance for the dollar...can't beat the Z06. Just imagine what you could do with the extra $65,000. :crazy: I'd rather buy American anyway. ;) :flag

For those of you who haven't seen that particular issue, I highly recommend picking it up.

The "911 TT vs. Z06" was simply a sidebar to the cover story about the super car shootout. It included a group of exotic "street cars" including a Mallett C5 and a Lingenfelter C5. The Millenium Yellow Lingenfelter walked away with top honors. Great article!!!

For starters. Add on the maintenance. Still it's a nice car.

Re: Porsche Twin Turbo vs C5 (MilYellow02)
 

I've been a CD subscriber for many years and think they get it right most of the time. What I like about them over some of the other rags is they manage to maintain a sense of humor about themselves and their profession. IMHO, it's all about having fun.

Re: Porsche Twin Turbo vs C5 (01C5fan)
 

"and in braking tests, stopping from 70 mph in 152 feet, 11 feet shorter than the Porsche can manage."

I have no idea how they could manage that in the real world. I have had 4 C-5's including a Z06 and an even half dozen Porsche Turbos, including my current TT. Porsche brakes are superior, period. No numbers to quote you, just experience.

BTW I feel the C-5/Z06 is the best bang for the buck but, you just have toexperience what twice those bucks gives you.

Re: Porsche Twin Turbo vs C5 (l2vette)
 

Well, as a one time Porsche enthusiast, I'll give my .02 here. First, I will say that Porsche's aren't any more sound in terms of repairs than vettes or any other car for that matter - I don't care what the Germans tell you. I've had a 944 and 928s and when they break (and they do!!!) you will pay lots of money!!!

On the 911 issue, I've driven 3 different 911's, 2 of them Turbos. A few years ago I drove a '96 (I believe it was a '96 because there were a couple of years where Porsche didn't make Turbos) 911 Turbo. That car was amazing. 0-60 in 3.6 secs and the responsiveness was the best I've experienced. Interestingly, the Porsche TT's of today are a little slower than the stock car I drove - don't know why. Perhaps AWD's are heavier, not sure

Anyway, I'll be objective here. The 911 TT can do things that the C5 cannot do without significant mods - I'm not just talking about hp. Even with those mods, the C5 cannot quite match the center of gravity of the 911. The 911 is the most road responsive car I've ever driven even though it looks butt ugly (except the Slant Nose like in the late 80's - that was a cool looking Porsche!). But it does have the price tag and as mentioned, its not any more sound in terms of longevity and repairs than the C5.

With that said, If I had the money, I would invest in LPE's TT and enhance things like skid pad, braking, tires, etc. Then the difference would be negligible and I'd rather do that then spend $120K (or whatever it is) for a 911 TT which will fall apart sooner than you think.
