sutol 0 Posted January 12, 2007 I've just removed this monstosity from the front of my 205 it weighs...I think I'll weigh it later! Does anyone think it is worth putting in the track car for extra cooling or shall I go with a slim one This one is 2.5 inches thick or 6 of those metric spaces on the ruler (old person ) Share this post Link to post Share on other sites
sonofsam 5 Posted January 12, 2007 (edited) No need to way it yourself, wouldnt want you to put your back out http://forum.205gtidrivers.com/index.php?s...=weights+thread Diesiel rads are thicker arent they. Alloy nissens rads are probably what the track boys use. Edited January 12, 2007 by sonofsam Share this post Link to post Share on other sites
sutol 0 Posted January 12, 2007 Just nipped out and weighed it on the bathroom scales Without water but including the fans etc it comes in at 32lbs Share this post Link to post Share on other sites
pug_ham 245 3 Cars Posted January 12, 2007 Diesiel rads are thicker arent they. Diesel rads are the same as the GTi but the Turbo diesel rad's are nearly twice as thick. A track car with a decent standard rad should cope fine, mine does on an 8v along with quite a few other people on here that have 8v or Mi16's fitted. Graham.

sutol 0 Posted January 12, 2007 Thinner is better these days as long as the coolant is flowing I suppose. They recon a Mini Metro rad is good enough to keep 2 ltrs cool and it's wafer thin anyway -- just testing the water Share this post Link to post Share on other sites
Sandy 191 Posted January 12, 2007 Get air to and away from it is the most important thing IMO. Most of the sprint/hillclimb 205's I work on use 1.1 radiators without any issues. Ok sprinting isn't as demanding as a 30 minute track session, but in reality it probably keeps the engine cool beyond the proper heat range of your tyres or brakes.

Just as a matter of interest and to save searching/trolling... How far forward can the rad be put or is it more impotant to seal the engine bay and use air pressure ?

Sandy 191 Posted January 12, 2007 We tend to mount them low and tilt them back with alloy panelling to force the air to go through the rad. The air beneath the engine bay should be at lower pressure than in front of the rad, so the flow goes down from there. We don't have access to a wind tunnel to prove it, but in practice there's no overheating. Share this post Link to post Share on other sites

Normski 1 Posted January 13, 2007 I've had 2 replacement radiators (standard), and the first (and the original) one was a copper core, but this latest one has an alloy core and it is far lighter. I can't detect any difference in the cooling. Share this post Link to post Share on other sites
welshpug 1,677 Posted January 13, 2007 one plus point of the Nissens rads is that theyre also one of the cheapest rads available, around £40 from GSF, way cheaper than on EBAY! no problems keeping my road car cool with that, but make sure the rest of the system is up to scratch, I.E hoses, metal pipe, thermostat and rad fan switch Share this post Link to post Share on other sites
