I gave up with all that stuff, that I never looked at, I found that I was too busy looking elsewhere, in front,behind, to each side and then there's braking, steering you know all that driving business... My shift lights, now, only flash at 7000rpm which gives me time(just) to get the change in before hitting the limiter. The flash is very bright and can't be missed, even in the following car 😬

What would be the weight saving over a Caterham SLR 421 system with 7inch silencer ?

Is yours the converted washer bottle affaire ? I re routed the pipe from the 'conning tower' so that there is a good length pushed into the plastic bottle, this seems to have stopped the automatic anti rust treatment.

Antony, Thanks for the info, do you have the Z shaped bit of alloy? I presume that this runs from the bottom of the water rad to the top of the oil cooler, in such a way as to seperate the two air flows. I have also just fitted a big rad, I worry that even if I fit an oil cooler, the extra hot air created will be held under the bonnet, raising the under bonnet temperature and therefore raising the oil and water temperature. I've a second bonnet into which I've cut two cutouts, one for the throttle bodies and the second above but slightly behind the exhaust manifold, I'm hoping to create an airflow across the motor.I have yet to try this and with the luck I'm having at the moment, it'll fly off and hit me on the head the first time out ☹️

Martin, Thanks the photo's will be most welcome. Peter, If there isn't a real risk of cavitation, that just leaves the temperature problem to resolve. I see that your looking for sunshine, it's come back to France this week we're promised over 30° for the rest of the week. The extra 10° or so pose major problems for a Caterham cooling system designed before global warming was even thought of.......

Martin,How/where is the oil cooler fitted ? I'm trying to work out how to get the oil cooler in, without compromising the water radiator. RedSLR's set up seems to be on the right track.

I'm a bit further south.......... I'm sure that I've seen photo's of R500 with a tiny Apollo, the oil cooler was hearsay,

Thanks Red, I get the general idea, what is the oil cooler attached to and where have you routed the hoses? Paul

Any ideas ?

ERRR does anybody know how the Oil Cooling on a Caterham dry sump system can be improved ? It has been sugested that the Caterham dry sump system is prone to cavitation at high revs, I wonder if there are any improvements that could be made to the standard dry sump system. Does the R500 have a different dry sump system to say that of a R400? I seem to recall that the R500 has a small Apollo tank, does it also have an oil cooler ? If this is the case where are they positioned ? Edited by - paulo on 1 Sep 2006 20:49:50 Edited by - paulo on 4 Sep 2006 16:25:04

Talk to Gary May, Freestyle. If the car has already been set up rake, cornerweights etc, try turning in on the brakes and get on the power once you're sure the cars turning. All that worked for me.

Sorry, if i wasn't clear, it used to be an R300 spec. The change is quite dramatic 😬 We could argue for hours about the power recorded, but who cares. It's much too fast enough........ which is the result I was looking for.

Tony, Jason langan (Hellier) built the engine,it has a reworked MS2 head with Jason's own cams,omega pistons, roller throttle bodies rebuilt by Minister, a Caterham 4-2-1 exhaust, lightweight flywheel and a MBE remapped by Steve Greenald. regards Paul
