What kind of time would an R500 do round
Discussion
Was at brands last year with a friend in his SLR and we were right up the backside of a black SR3 radical for about 5 laps, but couldn't quite get past....
I reckon 50-53 secs is fairly easily achievable.
PS Mr.Radical driver, your car should go a lot faster than an SLR!!!
(we were on A032s, not slicks) and the thing was understeering all over the shop!

For anyone that reckons that they can do a 49sec lap in a standard R400 on road tyres, you should note that the the quickest R400 lap on slicks is 49secs (a series that had top line drivers in it).
If your R400 has serious mods, then i would have thought it may be wise to state this before boasting certain lap times..

Think fergus was just out for windup. Sound like fast car / driver combo - you go so much faster than my Tr which has alot more power (250ishbhp)and is lightish 815kg - but not when compared to caterhams - we do very low 56 or high 55 if a good day on 32's. I am not lap record holder in mine - but out class if for load of different cars and mine looses out to more powerfull cars on longer track but better on slower one's - only a second off Gerry Marshall (different class) in his DB4 before he popped his clogs (and lap record there in my class) - I have shed loads of lap records. If you are fast you are fast.
Started post as the R500 in the workshop of other halfs Mini Cooper S (real one not BMW dross) - rolled off the numbers and just seemed nuts. Would no doubt hammer my 400bhp Chimera too (only place I could see Chimp winner would be on the Autobahns!)

According to a well respected Caterham race engineer none of the R500s that he has seen racing (including heavily modified ones) have beaten R400 race times round various circuits.
Remember the front running drivers in the R400 championship are seriously good drivers. If you see someone like Tom Ferrier at a trackday in a Caterham Motorsport club 1.6 Roadsport he blows people in much more powerful Sevens into the weeds! Another point to remember is that the fastest laps are set often with several drafts on the straights, cutting times down significantly.

No series for the R500 but a number were made into race cars and raced in JCC etc. There were a few R500R race cars built for Japan but not for here. The top series is now the CSR260 (article in this weeks Autosport). These cars are certainly quicker with the totally new chassis set up and stiffer chassis.
R400 was the top race series and is about to be replaced by the C400 which is the same chassis as the R400 with a 220bhp 2.0 litre Cosworth Duratec.

ding, just look at the JCC times of 2001-2002 and some of those times are R101 R500's with >230bhp
the R400 is a fast combination and as you say the drivers are very good with a very good setup. Some of them dont even dip under 50 seconds on slicks so a road R500 on road tyres would be doing extremely well to reach 51/52 IMO.
To illustrate the wide gulf between a road/casual trackday car and a proper race car prepped by a race team Autocar (chris harris or anthony reid driving IIRC) only managed 52.5-ish in the R500 evolution on a group test a year or so ago and that has a whole 50bhp than the r400 race cars.
intersting finchy, do you have a timesheet or url ? does the R500 time come from a particular race series ? A race R500 being significantly quicker than a race R400 to teh tune of 1 second on a 1 minute lap is not something that's been demonstrated in any of well documented race series in the UK.
