There seems to be a lot of misunderstanding surrounding Laminova's from the number of posts in the last couple of weeks.

As above a Laminova is an oil/water heat exchanger. If the oil is at a lower temperature than the coolant then the oil will be heated. If the oil is at a higher temperature than the coolant then the oil will be cooled - it's that simple.

In a Caterham, coolant is typically kept between 80 and 90 degrees by the thermostat opening and allowing the coolant into the radiator (an air/water heat exchanger) where it is cooled by the air passing through it.

With a Laminova fitted, when the oil gets hotter than the coolant (as will occur on track or on a high speed blat) the oil is cooled in the Laminova to close to the coolant temperature - the heat exchange capability of the Laminova will determine how quickly.

The size of the heat exchanger is important as it must have the capacity to exchange heat between the two fluids at a rate greater than the heat is being pumped into the hotter of the two. Equally the car radiator must be of sufficient capacity to remove heat from the coolant that is now absorbing extra heat from the oil.

So if you get the Laminova sized correctly and have a radiator of sufficient capacity, it is a very good set up.

I believe that the main problem with fitting an air/oil heat exchanger (a normal oil cooler) in a Caterham is finding somewhere to site it where it gets sufficient airflow without blocking the flow to the radiator.

Pistonheads seems a pretty good place to advertise.

Richard - you forgot the Bacon Roll bit - most important part of the day .

I have used a place in Slough called Quickstart for reconditioned alternator. Pretty sure they do starters as well. They are on 01753 567077.

Why not leave the poppers there and add double sided poppers to the aeroscreen? The trim that goes between the aero and the scuttle is enough to more or less fill the gap that will be caused by the poppers.

I've got footage of Wiscombe, Cadwell (a bit foggy ) and Harewood. It's all in car stuff. I can stick it all on a DVD and post to you if you let me know where to send it.

Results from Harewood are published here. Still searching for Cadwell park results.

Fine for no number plate is, I believe, normally £30 and no points.

One other thing to think about is that a number of the speedcamera databases have regular mobile site locations on them giving you the chance to drive a bit more carefully and/or keep your eyes peeled.

Radar and laser detectors are likely to soon become illegal see here about half way down. The bill failed last year but has been reintroduced.

GPS based systems will still be legal. On that basis better to get one of those.

I have a NavMan sat nav onto which I download the Pocket GPS World database so that is another alternative (TomTom, etc. all have the same facility).

Just checked the Palmersport website and the drive by is nominally measured at a distance of 20m with the car under full acceleration from 60mph. If you are near to Bedford, you can go there for a free noise check.

101db static is usually done by holding the noise meter 0.5 metres from the exhaust at an angle of 45 degrees to the tailpipe and then holding 3/4 of your maximum revs. The driveby I doubt you are going to be able to replicate - depends on distance from the meter, throttle opening, ambient conditions, which side your exhaust pipe is on, whether your induction is louder than your exhaust, etc. If you are borderline on the static test then there's probably a good chance of failing the drive by.

OK I missed the obvious joke 😳. 😬

Cheers Mark - I wasn't sure when they were coming back. Gill has left a message on Julies mobile but could you mail me Andy's mobile number just in case she hasn't got the message.

Andy - can you get in touch - we've got your new toy. Let me know if you want it charged up ready for the weekend.

On an Apollo install the Laminova is fitted in the return to the apollo tank. The water side is fitted in the radiator top hose. See here for good instructions (it's under the modifications sections).

Martin - sorry you didn't make Wiscombe but glad you've got the car sorted now. It meant there was only me and Simon Rogers in class 5 - you can gess what the placings were! 😳

Oil temperature can rise quite high on a long high speed journey (e.g. motorway) but trackdays will almost certainly cause high oil temperatures. GJT - your engine builder is wrong. Oil temperatures can rise much higher than water temperatures as there is no cooling of the oil as standard - I have seen 115 degrees oil temp on track (Stack dash so fairly accurate).

The apollo + laminova + Radtec combination does a very effective job of taming this. The important thing when using an oil/water cooler is that the radiator is up to the job of dumping the extra heat from the oil. A lower rated stat is not really necessary but I'd probably go for an 82 degree one anyway.

Er...here maybe?

I had a similar problem with by Bernard Scouse airbox. The solution for me was to put 3 washers under the driver's side engine mount to raise the engine a little on that side. This might work for you although by the sounds of Myles' problems it is then possible the plenum will foul the bonnet.

We're staying in Colyford - which pub are you going to?

You could get similar power for less money - have a look here.

It is horses for courses though and the advantages to the average buyer of having a factory fit, MOT friendly upgrade are not to be sneezed at. If you are not likely to sell your car and maybe have an eye to future upgrades then the aftermarket route is perhaps better and certainly better value.

The standard Caterham air filter for K-series engines is from Pipercross and is good for well over 200bhp (works fine on my 227bhp engine) and is £31.73 from Caterham (see here). Alternatively you can clean and re-oil the one you have but for the price it's probably not worth it.

I read that as acknowledgement of application rather than entry. Most of the other sprint organisers have emailed acknowledgement of a place - I hope Wiscombe will too since they requested an email address on the form.

Yes you can. The Varley Red Top is an absorbed acid battery i.e. same basic tech as your normal lead acid car battery just that the acid is absorbed in glass mat. I use an Optimate on my Red Top 15.
