I have no idea to get them down.<br>Radiator core is 68x48cm x 5 cm. I suppose that should be enough. I've experiment with different restrictor plates with no change. Changing pump speed didn't help either. The difference between radiator in and outlet is 10°C (50F). Not enough I would say. Maybe making the pump more slower? It was running on a ratio of 0.8 slower than crank, currently 1:1 speed. </span><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D">Any ideas? 10 Liters are circulating.</span><o:p></o:p></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D"> </span><o:p></o:p></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D">Cheers</span><o:p></o:p></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D">Chris</span><o:p></o:p></p></div></div></div></blockquote><blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"><div><p class="MsoNormal" style="margin-bottom:12.0pt">_______________________________________________<br><a href="mailto:fot@autox.team.net">fot@autox.team.net</a><br><br><a href="http://www.fot-racing.com">http://www.fot-racing.com</a><br><br>Donate: <a href="http://www.team.net/donate.html">http://www.team.net/donate.html</a><br>Archive: <a href="http://www.team.net/archive">http://www.team.net/archive</a><br>Forums: <a href="http://www.team.net/forums">http://www.team.net/forums</a><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/fot/gblake58tr3@icloud.com">http://autox.team.net/mailman/options/fot/gblake58tr3@icloud.com</a><br><br><o:p></o:p></p></div></blockquote></div></div></blockquote></body></html>
