Trouble getting heat into CR500's in the dry? My race car has 30bhp less and I could overheat them within 10 laps of Brands Indy in October. I could get them properly warmed up on a green flag lap.

More likely the surface was too cold

You might want to look at your setup there. I raced on CR500s for half an hour at a time without ever over-heating them. I've also tested 45 minute sessions without an issue. Mine's a Roadsport A racing Caterham.

Rumour has it they are having another crack at this week so watch again on Sunday!

CR500s on a C400 (like OJ's talking about) get a considerably harder time than on a Roadsport. That said, they usually start going off on a Roadsport 20 minutes or so in on several tracks.

The stop/start way Top Gear do their laps isn't conducive to getting heat into tyres.

I'd be amazed if thats true. Maybe they read the thread........

Like we wouldn't all be watching anyway.

I'd also dispute their claim too. On ACB10s in the rain during an Irish tour some 4 years ago I could watch them dry on a petrol station forecourt before I'd finished filling the car up. I doubt I was driving as hard as Stig (although he'd have never kept up with me on the that day ).

1 minute and 17 seconds. That's not a lot of time to get heat into a set of tyres and then exploit it, is it?

[Mars]

You don't have to start each attempt with "out of the box" cold tyres though.

[sfaulds]

Really? My understanding of how it went was that there was sufficient dicking about between each lap to let the very low ambient temperature to do it's work. Of course, it could all just be a conspiracy.

[Mars]

I guess we'll never know. Would be nice to put one on ACB10s round the track in the Summer, just for our interest however I think the result as it stands served the purpose intended very well.

haha, setup are you kidding? RSA at 120bhp can overcook the tyres depending how you drive it although I didn't really have too much of a problem, but with 210bhp (thats nearly double maths fans) in what OJ drives I think you can overcook them very easily.

105mph into breaking for paddock in RSA as opposed to 120-130mph in c400. Work out what does the hard work! Obviously actual corner speed is similiar-ish.

I'll side with OJ on this that the surface was the bigger problem.

cool .. who told you ?

can only be to set a better time i suppose

[RobM77]

Fair comments about the CR500s My two Caterhams have been 120bhp and 156, so I've not run a more powerful one anywhere near 200bhp.

Can't wait to see the R500 again. Surely it's been just as cold if not colder, so I guess it was the faffing between laps and this time they'll only stop briefly.

I think it's quite well known now. Can't wait to see what they do.
