Outragous Wheelspin!
Hi
Went on the car's maiden voyage today(dad drivin due to my predicament )on a mildly moist road.The car seemed to ride very well in comparrison
to a westy my mate had,but it'll quite happily light up the tires in 3rd,even at 70+.Is this normal in damp conditions in peoples experience,or
is something super wrong?its approx 250bhp,shocks are set on softest setting,and as i said the ride is very good,and 195 something 15 yokohama a539s
at 20psi.

not got much first hand experience with se7ens so everyone feel free to shoot me down.
From my "younger" days of watching oldschool fords on the strips before getting into kits I would say approaching 500bhp per tonne in the
wet would easily light the tyres in 3rd..

try droping your tyre pressures down to 17-18 psi, bigger contact patch on the road

Yep. My BEC had huge grip in the dry but was very poor in the wet. My Peugeot 107, in comparison, doesn't seem to notice if it is wet at all.
Hurl it into corners at indecent speeds and it just hangs on. Perhaps its because sevens are very light with wide tyres and lots of power
(relatively).

first time i took mine out coming off an island at very slow speeds i managed to get it sideways.
I never noticed the difference with cold and hot tyres before i had my 7, now i know it makes the a huge difference.
Again let the tyres down, as low as possible to get the rubber moving and warming up quicker. i also found softening the rear shocks made a difference
also.
Take it easy these things hate slippy condition.
Sorry about my spelling, im an engineer and only work in numbers.

Yep sounds right......had wheelspin in the dry in third a while back.
Depends on your tyres as well....Ive got some russian made junk that came with the mags and they are good in both wet and dry. But I know of others
with fancy street legal slicks that have a poo time in the wet but the dry they are like glue.
Since it rains everyday in this cold mouldy island I stick with the wet/dry combo to stay on the road.
So the answer is just to take it easy....otherwise we will see you posting pix of an off road adventure

Brand new tyres in the wet isn't a particularly good idea. You should find that the wet performance will improve after they have had a few miles
in the dry - also tyre pressures as mentioned above
"That thing you're thinking - it wont be that."

Sounds about par for the course.
This is why we all say TAKE IT EASY until you learn how your car drives.
I have a V8, and as soon as its damp, it becomes very tail happy. Mainly down to loads of power and torque. Its easy to break traction, then spin it
into a ditch or wall, or tree, etc etc.
Take it steady, and watch out on damp roads, and worse still are damp patches under trees, hedges, and areas of shade where it hasnt fully dried out
when the rest of the road appears to be dry.
There is very good reason why everyone plugs the TAKE IT EASY message. Also concentrate on your driving and look at the road / surfaces / cambers /
pot holes as well as the traffic.
Maybee, I'm teaching Granny to suck eggs etc etc... But plenty of newbies will read this, so its aimed at everyone.
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

As all of the above. Mine spins in third in the damp (225 Bridgestone Potenza's probably don't help) and round corners my Megane gets the
job done quicker in the wet!

I wouldn't be surprised at all. I do not have experience in 7s yet, but i could do the same with my pick up truck in Greece with 80BHP and
1300Kg.

7 driving in damp/wet conditions is a definite recipe for ring twitter in my experience.
2 people on board does help a little as it holds the back end down more, but then when it does get way from you which it will, the extra weight works
against you like a sling shot
Dry miles only for me (unless you get caught out in the rain).

My tintop used to spin hugely in the wet with only half throttle so i put wider wheels and tyres on.
The old wheels and tyres are now going on the more powerfull and much lighter locost 
How long can i resist the temptation to drop a V8 in?

Check the corner weights you have a lot of power but one rear wheel might need more weight jacked on to it.

The cornerweights were bob on in the final build,and I'd expect the lsd to compensate alittle, but I guess it will have settled,I'll do
them again with afew more miles on the clock!

I went up the power range from xflow 1300, 1600, another more powerful 1600 then onto 2l Zetec on TBs. This helped to control the car but even the old
1300 boat anchor could spin the wheels in 3rd... It the wet unclean roads that do it.

Your LSD isn't helping in the wet, locks up and the rear of the car follows the crown in the road, open diff just blows all the excess power out
one wheel.
I drive a Jeep Wrangler with a LSD, total hell on ice and snow if the back end breaks loose

Have you set the dampers too stiff?

Ther great fun in the wet but also make you poo your pants. Mine snakes the rear in 4th in the wet if the roads are a bit greasy.

I have 14 psi in my tyres to try calm the backend.
Will happily snake up the road in 1st, 2nd, 3rd if theres any H2O present.
Chucking into corners, roundabouts are worse the back end comes round with the slightest bit throttle.
