Stuffed purple Tuscan??
Discussion
We are all casting ascertions over whoever was the unfortunate driver of this Tuscan.
For all we know he may have had to hit the brake to avoid some Mondeo driving prat who cut him up.
He may have had a mechanical failure.
When the crank snapped in the Cerberra I was driving it locked the rears. I was fortunate enough to get the clutch in very quickly and save it, it was also in the dry.
I would not like to have that happen to me at those kinda speeds in the pouring rain etc etc ...
Unlucky to whoever it was, but at least it seems they got out of it !

i.e. Dont boot it in the wet unless in a straight line and in 3rd?
Savage for whoever it happened to though.
Matt.
er...if I boot my Tuscan in 3rd in the wet it snaps nicely sideways....
which can be tricky sometimes...

I was leaving Blackpool last week just heading off from the lights in a straight line. 2nd gear at 40-50mph and the back end started sliding about. I was not even trying! The road was damp rather than wet - these Tuscans are seriously powerful motors and need the upmost respect. I too have heard that 3rd gear, 70 mph on a damp road can produce wheelspin.

Me, I drive like a granny with bad eyesight in a Metro when its bad.

I've had wheel spin on the motorway in 5th at 70 mph in the wet after I booted it - hit a bump, wheels lost traction on the up bounce.
However, it's still faster in the wet than most other cars as it's got more grip and lower centre of gravity e.g. it's faster than my old Fiat Coupe 20V Turbo.

Sounds the exact same rule that I use about 2nd on the bike! went out last night, it was a right laugh - for the hour I was out, I felt alive... then went down the pub after. Excellent.
Back to the topic, does make you wonder though, if you can't use ALL the power ALL of the time, is there any point in having so much power? maybe the electronic traction devices are a good idea when the going gets damp... only "wondered" for a short time though, 'cos there is no way I'd give up on the horsepower race!

Mmm, don't like the assumptions here. More grip, lower centre of gravity improve the car in an aquaplaning situation...
Bridgestone on their site say:
Factors influencing aquaplaning.
Water layer thickness.
Car speed.
The ratio, weight of the car / Tire contact area.
Tire thread design and pressure.
Shock absorbers.
Suspension.
Wide tyres, low weight makes aquaplaning MORE of a possibility. More weight helps, narrower tyres help. More power, lower cofg will not help at all in this situation. There are formula for this situation. They are scary!
At the end of the day, aquaplaning equals out of control on a public road.
Yeah, but I wasn't talking about aquaplaning. The Tuscan is faster on a wet road than most others - I meant going round corners not going flat out in a straight line - I hope that clarifies your assumption.
You shouldn't be driving in any car faster than the conditions allow. Aquaplaning is a specific condition that occurs when not enough water can be moved from underneath the tyre. I suggest you shouldn't be driving so fast in conditions that might get you into that situation in any car.
My loss of traction accelerating in 5th at 70 was caused by the weight on the rear wheels being reduced as the suspension rebounded as I went over an expansion gap on a concrete motorway. The wet road made it slippy enough for the wheels to spin. Nothing to do with aquaplaning.

Yes, OK, but I didn't want others to relate this to what could be an aquaplaning situation. You are saying that the Tuscan is quicker on a wet road than other cars. Maybe, but in some situations you ARE closer to aquaplaning than other cars . The original posting was about aquaplaning I think he said pi$$ing rain, so I did not want any comments in these posts to be incorrectly applied to the original post.
However my concern was that there is a condition where in stable state conditions, aquaplaning is not occuring but when suspension bounce happens in the presence of small amounts of water can cause aquaplaning to occur at a speed LOWER than the actual speed of aquaplaning in those water conditions. That is to say, on aquaplaning for whatever reason be it speed or bounce then the speed of the vehicle has to fall much below the aquaplaning speed for the wheels contact to be re-established.
[To quote from an RAF source]: Aquaplaning is a progressive phenomenon and significant losses in braking ability and in directional control will occur at speeds below total aquaplaning speed. Once aquaplaning has begun, wheels can spin down and stop fairly rapidly. However, it will take longer for wheels to spin up again after speed reduces below total aquaplaning speed. Aquaplaning, once begun, will persist to a speed lower than that given by 8.6 P^-2 P. thus, pools of water may initiate aquaplaning and that condition will persist long after the aircraft has passed through the puddle. [unquote.]
Next time we drive down the motorway in pouring rain on your 35 psi tyres at 70 mph (who goes faster)? we need to be aware that we could be well into the total aquaplaning region and find ourselves making sudden contact with the barrier or that big truck a few yards ahead.
If your tyre pressure is lower than 35 then just calculate the aquaplaning speed! And the formula does not have to take account of the tread on the tyres!!!???

Not directly related to this thread...but broke a crank
...what, as in engine crank shaft!!!!!!!!!!!!!!!!! 
I wonder what Steve Heath and TVR would say about that. 
I have never heard of a crank breaking, not even on rally cars! Perhaps I lead a shelterd life?
Hang on whilst I check my Griff's crank is OK! 
. They're not evil, you just have to adjust your driving technique. You don't have to stamp your foot on the gas pedal every time you change into 2nd or 3rd gear! It's just that you can
