dudlow Posted November 14, 2007 Share Posted November 14, 2007 Took delivery of my 05 CSR today. There is no redline on the tacho, what is the safe rev limit, and is the engine fitted with a rev limiter ? Any owners tips would be apreciated. Thanks.

6speedmanual Posted November 14, 2007 Share Posted November 14, 2007 When there's a loud bang and hole in the bonnet and a puddle underneath, well, the rev limit is around there somewhere 😳 😬 ...ducks.... 6SpeedManual *tongue*There's no such thing as too much BHP per Ton 😬 Link to comment Share on other sites More sharing options...
mav Posted November 14, 2007 Share Posted November 14, 2007 Not useful 6 speed - Should be around the 7500 range. once warm and out on a run, take it up to the limiter in 2nd, then change up. don't do it on the down change.

RWHomer Posted November 15, 2007 Share Posted November 15, 2007 Yes fitted with Rev Limiter at around 7500 rpm CSR260 Hillclimber Link to comment Share on other sites More sharing options...
dudlow Posted November 15, 2007 Author Share Posted November 15, 2007 Thanks RWHomer. After a good blat today, I am discovering that the 260 has got an amazing engine, it pulls like a train at any revs, but press on from 5-6k and its mental. I am used to many years of top sports bikes and Porche/Ferrari type cars, but this is so raw and aggresive in the power delivery its like nothing I have driven before. The back end was coming out around not too fast bends, but I am putting that down to 4 degrees C and rear tyres that have seen better days (Avons). Am I best sticking with the Avons, or are there much better tyres out there, am I best sticking with Caterhams recomended 24fr and23lb rear ? Which oil is best, as I think it may be prudent to do an oil/filter change as the car has been doing nothing for 12 months. Roll on the spring, I just love this car !!

Road Terrorist Posted November 15, 2007 Share Posted November 15, 2007 Hi Mr Dudlow, Caterham obvious recommend their own motorsport and having it serviced by them they only use their products. Tyre grip only from my own experience and style of driving is better at around 20psi front and rear, smooth cold road at low temps has relaxed my 🙆🏻 on several occasions If in doubt flat out !

mav Posted November 15, 2007 Share Posted November 15, 2007 5w50 is what is reccomended by CC and Cosworth.

6speedmanual Posted November 15, 2007 Share Posted November 15, 2007 D J 😶🌫️ (and neat little K dig too. hehe Errr... this posting is not a joke.[serious smiley] Engine management rev limit is set to 7700rpm. here is a very useful info source (also for k 😬 ) Some type of ecu controlled fuel injection cut-off will be applied which acts across the various injectors in sequence to give a softish cut. (good ol'fashioned ignition cut no good as it can allow unburned fuel down exhaust into cats) Mechanical rev limit (which could possibly be important if one is in the habit of downshifting at excessive roadspeed for the gear....???? Dunno???? Maybe one of the tuning experts or a EuroCup racer would have information on this. I would hope the unit would be robust to at least 8250rpm if the engine management allows powered revving to 7700. What lets go first? Rods/pistons/valve gear???? AVONs..... The CR500 is an exceptionally good tyre but as with any subjective aspect of car grip/handling this is a subjective point and there have been many debates about this previously. What I can confirm from speaking with an AVON motorsports division engineer is that the rubber compound does not really get out of bed until ambients of over 10 deg C. On these cold mornings we're having, the CR500 is soundly snoring with pyjamas and nightcap on. Worth exercising great caution in these winter months. Also the rubber compound is about dead after two years. This is not too much of an issue as they only last 3-6000 miles. But beware the very low mileage "garage preserved" 7 still sitting on original tyres at 4 years old 🙅🏻♂️ Will be distinctly skittish , especially in the wet. ......end serious post. 6SpeedManual *tongue*There's no such thing as too much BHP per Ton 😬 Link to comment Share on other sites More sharing options...
dannylt Posted November 15, 2007 Share Posted November 15, 2007 Nothing much you can do about mechanical overrevving on downchange apart from having a computer controlled transmission. But I can't imagine an occasional blip well over this mattering. Certainly I had a rev limit of over 8300 for a couple of years with similar top end/rods/pistons - but also a steel crank for safety (which the CSR260 doesn't have). Anyway, just enjoy! The CR500 is probably the best compromise road tyre, and with that much power and weight it's always going to wheel spin at some point, especially when this cold...

dudlow Posted November 15, 2007 Author Share Posted November 15, 2007 Really usefull info, thanks very much. I will also make extra sure about checking the oil level very regularly after reading Markie1's post, it would seem to be critical . Presumably if it spits into the overflow tank its not a problem.

paul jacobs Posted November 15, 2007 Share Posted November 15, 2007 Further on the tyre issue, Avon are the only manufacturer to make a tyre of 245/40/15, so you have no choice, you could of course go down to a 225/50/15 which Yoko make, but it would be a stretch on the 9" rim.

Sheds Moderator Posted November 15, 2007 Share Posted November 15, 2007 I used to run Yoko 032Rs and they were very sketchy in cold damp conditions. Drive carefully and make sure you know your grip levels (a nudge on the brake works wonders!) before using too much power. Link to comment Share on other sites More sharing options...
dannylt Posted November 15, 2007 Share Posted November 15, 2007 Oops, I've just remembered - there are other top end mods required for 8000+ rpm so I take that back. No excuse to over rev it anyway! Link to comment Share on other sites More sharing options...
