top speed?

[magpies]

What top speed do you get (should be reasonably accurate using SatNav) - need to know tyre size and rev limit

[S2Mike]

Will have to wait until I travel on the Autobahns of Germany...

[Spanish S2]

130 ish

[TurboTony]

Probably limited to how light the car gets at speed and how brave (foolish) the driver is before they chicken out. I've never taken J-LLO over 110 (in Germany!) but always aware that the road needs to be clear with no possible incidents. They don't stop so well as some modern cars from high speed so I think that this governs the effective vmax.

Hi Sp2 130mph.....sounds good but at what revs and tyre size?

There's a handy tyre size x speed per 1000rpm x gear ratio chart in the Steve Heath book


V6 S on standard (205 / 60 x 15) tyres should be doing 24.6 mph per 1000revs in fifth

130!! Brave guy. I would need a good nappy fitted before going over 110 in the old girl

[phillpot]

I'd need a very long straight (downhill) road and a following wind !

[greymrj]

And a nappy?

[Scoobimax]

Depends how much room you've got and bravery as mentioned above.

110 mph on an airfield and it felt more. Not sure I'd take it much higher. All on standard wheels/tryes

[AutoAndy]

....wot Mike said...let's see on the autobahn in Germany on the Eurotour this year...should get a good average over all the cars with views on tyre sizes, bravery etc

Failing that, I believe that the fast oval at the Bosch test track is banked....my personal target is 200mph (after all you won't get the most out of life if you don't raise your expectations)...I think I need to shed a little more wight from the car..

If mine got to 200mph I wouldn't expect to get any more expectations out of life, period!

Max your speedo said 120mph, top was off too

Oh good I thought it was just me... I believe better front aero is the key.. A air dam + splitter perhaps

No wind help too on a windy day 80 is a bit unnerving

You're right Bob - I blame my age for failing memory.

It was the braking distance that worried/limited me

[Smokey Boyer]

I got mine (V6) up to 130mph, but not a lot more, on the Bruntingthorpe airfield as part of the Asda On Your Marks charity day last year.

I also think mine was the slowest car on the back straight as well, with almost everything passing me.

And how old were your tyres on the day?

One word: cojones!

[AutoAndy]

...ref my earlier comment i have changed my mind.....

...I don't want to reduce weight, but increase it a little for stability......

....how much does a Veyron engine weigh?

[Brummmie]

You don't need a veyron engine, my ls3 based engine in a cerbera has achieved 202mph at brunters, with data logging.
£10k if you are handy with the spanners might get you to the double ton?

130 on an RAF runway in heavy rain but the front end was lifting a fair bit and I would not have gone faster if I could, schimg was doing about 170 in the cerb though and Bob about 155 in his Tam I think.

Now, the next year on a dry day in the cerb was about 165 on a much shorter track with odd smelling brakes at the end

This year who knows...... ;-)
