Quick bit of theory: weight has no relevance to top speed if you are on the horizontal. Surprising but true.
Weight has a big impact on ACCELERATION [F=ma] and power to weight will give some guidance to the accelerative capabilities of a car.
TOP SPEED occurs when motive force = aerodynamic drag. So top speed is simply a function of power (and correct gearing) and aerodynamics.
Also don't forget that speedos tend to over-read, usually by about 10% if you look at Autocar's test results. ie: if you indicate 180mph, your real speed is probably closer to 165mph.
My view: unlikely that any standard TVR (RR Cerb + Tuscan S included) could exceed 200mph but I'd like someone to prove me wrong! Be careful!

Never went above 150 mph in my Cerb S6 as it felt very light at the front and did not inspire confidence. I had plenty of power to go but just felt unstable at those speeds. In my opinion, it takes a very brave (or stupid??) person to go much above 150mph in a Cerb.

Pikey faked that.
I guess this subject could run & run but I tend to agree that a REAL 200+ in the old Cerby seems a tad unlikely. I had been running mine since new in '99 when a quick trip to Cannes the following summer beckoned...
The acceleration in these things is always quite special and I still recall it's exponential lunge to an indicated 170 and the way most vehicles (and living creatures within a half mile radius) were reduced to awestruck (and indeed very frightened) spectators. My speedo was still advancing albeit much slower but it did creep around to a tad over 195 - there WAS more to come (another 5 or 10 INDICATED, perhaps) but even Europe's finest routes have bends in 'em!
Stability was fine, apart from a slight edginess between 135 and 145 but below and above it was fine - probably just camber/surface effects: indeed, a 928S4 a year before showed 160 on the speedo and felt no more planted - which IS a good thing for TVR. Unfortunately, when I came to rest at the next Euro checkpoint the exhaust sounded unusually resonnant and had split asunder but hey, you've all heard this record...
My current pride is a modified 993TT which feels massively quicker (no bull): this car seems to get to biker hero speeds like any RUFfian I've read about and would surely crack the magic barrier in reality (490 BHP) - although one of the technicians associated with the mods reckons as a rule of thumb you need 500 BHP or so...70 MPH limit - deary me. Still, if the original Diablo DID 200+ with just under there's hope yet!

derestrictor,
I'm considering buying a Cerbera 4,5 (new).
But theres the 993TT, ...a serious option.
I had a short testdrive in a 4,5 LW Cerbie .. just breathtaking!!
How does the acceleration feel in comparison?
I drive a lot in the mountains, and need a car that does the bends just as well as the steep straights ...getting both is not an option

Zubi - you drive in the mountains a lot? Wow! Can I come?
In answer to your question, the Cerby WILL blow you away the first time you experience it but living with it IS a different story (see countless threads!).
Given your requirement IT HAS TO BE THE PORKER! Even in standard 408 BHP form it will maul the TVR up through the Alps...
I know you won't want to hear this (probably) but for 'mountaineering' I'd love to compare a 993TT or even the 996TT against ANY EVO VI or VII - there's far less romance and swagger for sure but hey, that there rally technology is wild (only REAL problem is the 150 mile range when driven in anger - the tank's pathetic!)
But at the end of the day, the combination of sheer passion & ability means you simply must buy the German.
Good hunting and let us know what you decide.

I have to agree with the Porsche over the TVR, I had a Cerbera and now have a 996 TT they would be pretty equal in a straight line but the TT would leave it for dead on the twisty bits without even trying.
You will also need to factor in the weather that you will get in the mountains and every day use etc, it's a no brainer...

dannyIT in his Cerbera RR 4.5 LW having had the Joospeed magic worked on it would leave any Porsche TT in a straight line or round the twists from what I hear.
Flame away
I think that we are talking standard cars,or as standard as a Turbo or Cerbera can be :-)
You can do far more with a Turbo than you can to a Cerbera,I've seen a 800BHP road going 996 TT totally outstanding..... any other stories of highly tuned Cerberas/Turbos ???
Steady on chaps! Let's keep our heads and realise sommat here - BOTH the 993/996TT AND Cerby are totally involving, stimulating masterpieces. As I've said, having owned a 4.5 Cerb and then changing to a somewhat uprated 993TT I still get strange stirrings in the pantaloon department whenever I oggle Blackpool's finest...
I think we all acknowledge custody of both would be ideal so 'Vive la difference!'
For my own part, however, I'll n'er forget the first drive in the Porker on my fave backroads round here...even at the time as a standard 408 machine, it's sheer poise and traction and indeed general 'any gear/speed/rev-range' flex was astonishing: within minutes I was overtaking where I wouldn't have dared with the TVR. Fundamentally, the 993/996TT IS IMHO always going to be quicker A-B than a TVR and for straight line oomph (one of my personal Euro obsessions) it would really be very close depending on individual car specs...

Hmmmm. Id beg to differ.
All depends on the drivers.
Ever seen a tuscan in the hands of a race driver, up against another race driver in a porker turbo on proper tarmac?? I have, and lets say the salesman from porker UK looked a bit red, especially as the tuscan wasnt even a red rose or an S.
Fun and games
