EPnick22 Posted July 11, 2013 Share Posted July 11, 2013 looking at getting a few new bits, running a stock rad at the moment, wouldnt a half size rad give less cooling efficiency than a full size rad like this? http://www.tuningdevelopments.co.uk/product_info.php?products_id=1152 just curious of the difference that's all.... cheers Quote Link to post Share on other sites
StuDoc 72 Posted July 11, 2013 Share Posted July 11, 2013 (edited) Yes the full size would offer better cooling but its not all about cooling. Coolant must be held at the optimum operating temp this is done by the thermostat opening and then the water being allowed to flow to the rad to be cooled to come back and do the same again. So theoretically if you have too large a rad then you would actually cool the water too much and cause the thermostat to open and close allowing the operating temp to drop which is bad. There is a point reached where no matter how expensive well designed thick or wide a rad is it can only so efficient. My point being that half rads do the job as well as a full rad. Aslong as your coolant is not overheating then thats all that matters. Also they are half the size so it makes sense. I think even if the car is used on track rather than go back to a full size rad people tend to just fit a lower temp thermostat.

EPnick22 Posted July 11, 2013 Author Share Posted July 11, 2013 hmmm that makes sense, cheers buddy the half size is cheaper anyway Quote Link to post Share on other sites
daniel_g Posted July 11, 2013 Share Posted July 11, 2013 With some turbo setups its not possible to run a full size rad due to clearance issues, so if youre looking to go for a bigger turbo upgrade then buying a half size rad now makes sense Also the thickness of the half size rad matters, i ran a triple core to try to keep the temps down, i had no heater matrix so temps would have been slightly higher. Also withe the half size rads youre better off using the proper mounting kit from J.D performance on this site Quote Link to post Share on other sites
EPnick22 Posted July 11, 2013 Author Share Posted July 11, 2013 i was looking on T.D at the half sizes, im only on a stock ct9, fmic etc etc, would a twin core or triple core be better? Quote Link to post Share on other sites
Fozzie Posted July 11, 2013 Share Posted July 11, 2013 I was planning on going with this one for mine; eBay item number 380674214730 Quote Link to post Share on other sites
daniel_g Posted July 11, 2013 Share Posted July 11, 2013 Up to you really and what youre gonna use the car for, i went for the triple at the time because it was only about 15 quid dearer at the time. From that cunt at cj performance :/ Quote Link to post Share on other sites
EPnick22 Posted July 11, 2013 Author Share Posted July 11, 2013 wow thats cheap for the flee-bay one? £110 cheaper than the one on T.D bloody hell, hope it isnt a dud cause I'd happily have that for the price! Quote Link to post Share on other sites

From that cunt at cj performance :/ well i only use it on the road but usually on the weekends im boosting a lot of the time, only running .8 bar on a ct9 Quote Link to post Share on other sites
jayc-glanza17 Posted July 11, 2013 Share Posted July 11, 2013 my twin core civic rad runs fine with 320bhp for road use..im selling it soon, as need a more efficient one for track use Quote Link to post Share on other sites
Burny Posted July 11, 2013 Share Posted July 11, 2013 I went for a full size rad and low temp thermostat, better safe than sorry i say lol Quote Link to post Share on other sites
