knowley Posted April 26, 2004 Share Posted April 26, 2004 After searching & reading lots of posts on radiators and Laminovas I have a question or two I plan to fit a Laminova as the 120degree oil tempreature reading is not to my liking, although I understand is normal on track. I don't race as such but do trackdays and enjoy the summer heat so is there any need to upgrade the radiator? If so should I go the whole hog and get a Caterham Race radiator or will the Radtec replacement radiator be ample?

mav Posted April 26, 2004 Share Posted April 26, 2004 I still run the std ali rad with laminova... I will be upgrading to the cat triple or radtec next year pre usa tour... Link to comment Share on other sites More sharing options...
Anthony Posted April 26, 2004 Share Posted April 26, 2004 Hi, suggest you change one item at a time ( this not a suggest I have followed on my car 😬) and it will help enable constructive development. You can always change rad afterwards and go for best quality you can afford If you go for a laminova have a look at the medium size one ( c.250 mm ?) the small one is I suspect not going to help much and the large one will probably need a hole in the bonnet. My one fitted nicely under nose cone at an angle between head and rad. Regards Link to comment Share on other sites More sharing options...
knowley Posted April 26, 2004 Author Share Posted April 26, 2004 So the standard radiator can cope The Laminova came with the car (thanks Simon) so it should be the right size 😬 Edited by - knowley on 26 Apr 2004 19:24:18 Link to comment Share on other sites More sharing options...
Paul McKenzie Posted April 26, 2004 Share Posted April 26, 2004 I think the standard ali rad is OK I just changed from the standard steel/brass/gunmetal effort on my HPC to an ali rad off a K ☹️, and despite all my reservations of consequent massive coolant leaks and HG failure like all you K boys have , the thing actually works , and in fact my coolant temp has fallen by 10 degs.

Peter Carmichael Posted April 26, 2004 Share Posted April 26, 2004 The Caterham triple pass one is, as far as I understand, designed completely the wrong way to achieve what it sets out to achieve. Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted April 27, 2004 Support Team Share Posted April 27, 2004 The standard black Caterham radiator is highly unlikley to cope but the ali one might - keep an eye on your water temperature on track as the Laminova will be dumping heat from the oil into the cooling system. I found that not only did the oil temperature get to 120+ but the water temp was well over 100 as well. I fitted a Laminova and a Radtec radiator at the same time and now after a 20 minute track session (on a hot day) the oil will be less than 100 and the water in the high 90's - a great improvement and temperatures that I am a lot happier about.

NigelR Posted April 29, 2004 Share Posted April 29, 2004 An additional method, which I can highly recommend is using a product call "Water Wetter" I have used this in the past in a single seater, where overheating could sometimes be a real issue on a hot day and it really made a big difference in dropping the temparatures. You can pick it up in race supplies shops like demon tweeks. It works by breaking down the surface tension of the water in a cooling system thereby improving heat transfer from the engine to the coolant and from coolant to radiator. Not sure if there are any similar products? Caterham SV-R – Coming soon - Will it meet your expectations and budget? 🤔 Link to comment Share on other sites More sharing options...
