stutz 712 Posted July 27, 2017 Share Posted July 27, 2017 (edited) Does any one have any thoughts on cooling a 750 hp E9 in a superliner? I have seen some for sale that have electric fan set ups and wondering how well that works and who builds them? Any other solutions?

MACKTRUCKS4 Posted July 28, 2017 Share Posted July 28, 2017 I'm running about the same HP. I put a aluminum core radiator and switched ELC for coolant. No problems with over heating.

stutz 712 Posted July 28, 2017 Author Share Posted July 28, 2017 Who did you get the core from and are you running a viscous fan drive? What is ELC coolant? Quote Link to comment Share on other sites More sharing options...
ekennedy21 Posted July 28, 2017 Share Posted July 28, 2017 (edited) To me, ELC just means Extended Life Coolant. Thats what cat calls their red coolant anyway. Edited July 28, 2017 by ekennedy21 Quote Link to comment Share on other sites More sharing options...
AZB755V8 Posted July 28, 2017 Share Posted July 28, 2017 (edited) I have an E9 that is turn up real well, actually I have backed it down a bit lately. It had 4 electric fans and no viscous fan on the engine. It worked well but put a good load on the alternator all the time. It was done for pulling to get the 50-75hp that a viscous fan would use at pulling RPM. The engine driven fan works and I have tried the original as well as a retrofit unit with fiberglass (plastic) blades. It is mandatory in most sled pulls to have plastic fan blades now a days. Make sure you have the big 4 core radiator and it is clean inside and straight and clear fins on the outside. Mike is running an Aluminum radiator but in all the engines I have, a copper core actually cools better. Heat transfer by the thermal numbers is greater for copper over aluminum. Yes, Aluminum for weight in a race car... is the way to go. The big thing is no matter what the power output 500 or 1000hp the easiest thing to control heat is backing off the throttle when the water temp and pyro get to high. I have only had to back-off a few times pulling a good grade loaded, but still passing anything and everything in sight. It will recover in 2-3 minutes then lay into it again!!! When you put a good load on the alternator, like with electric fans, with an E9 or spin it past 23-2500 RPM's the belt likes to flip in the pulleys. I always have a spare belt or two in the tool box. I am working on a two belt set-up to stop the belt roll. Edited July 29, 2017 by AZB755V8 spelling 2 Quote Link to comment Share on other sites More sharing options...
