dritchie Posted July 17, 2004 Share Posted July 17, 2004 Trike WITH body http://www.cyberonic.net/~dritchie/srrear.jpg Trike withOUT body http://www.cyberonic.net/~dritchie/FIN2.jpg Having trouble keeping temp below 220 degrees. Any ideas ??? Link to comment Share on other sites More sharing options...
MorganM Posted July 17, 2004 Share Posted July 17, 2004 Looks pretty restrictive on the air flow over the radiator with the body on. How does she cool with the body off? Sweet ride by the way, well done. Link to comment Share on other sites More sharing options...
Turbone Posted July 17, 2004 Share Posted July 17, 2004 I agree with Morgan, on all counts. What are you running for fans? I think you were considering this when you were putting the engine in a while ago. Link to comment Share on other sites More sharing options...
archemitis Posted July 18, 2004 Share Posted July 18, 2004 i like 180degree thermostats. looks like a summer (mostly) vehicle, so it should help. might be as simple as adding an inch of space where the radiator is mounted, or making a scoup to direct air flow. or oil coolers are cool , and you could stick one right in the air flow, they make a huge difference. looks like fun Link to comment Share on other sites More sharing options...
beachbum Posted July 18, 2004 Share Posted July 18, 2004 ok guy i got a ? for ya and it might sound dumb but hear me out cause ive seen plenty of people do it ok? 1st off compared to a car ur engine and radiator r backwards, so technically ur fan is pushing against the airflow coming thru the radiator,back into itself, i guarantee u if this is the case and u reverse ur fan wires it will run cooler hope this helps and if it does let me know. thnx bb Link to comment Share on other sites More sharing options...
beachbum Posted July 19, 2004 Share Posted July 19, 2004 dang i didnt realize somebody had already told u the above till i was looking thru the old threads. sorry:banghead: Link to comment Share on other sites More sharing options...

Scoobywagon Posted July 19, 2004 Share Posted July 19, 2004 That is one spiffy ride! I'm kinda wondering if you couldn't just louvre the black piece that appears to lay across the "engine bay". In the pic, it looks like and inlaid piece, perhaps with hinges? Might try putting some louvers in that and if you STILL can't keep it cool, the perhaps some sort of airbox rig inside there to help direct air to the radiator, assuming sufficient inside clearance for such a beast.

dritchie Posted July 19, 2004 Author Share Posted July 19, 2004 I wish I could have seen more of a front view of your trike to get a idea of how the airflow will get into the radiator, both with the body on and off. It looks like the front of the radiator may not be receiving near enough airflow to cool it. Here are a couple pics that MAY help you get an idea of "limited" air flow http://www.cyberonic.net/~dritchie/srrf.jpg http://www.cyberonic.net/~dritchie/FIN1.jpg OR look at the whole page http://www.cyberonic.net/~dritchie/s_r_pics.html Link to comment Share on other sites More sharing options...
leeschaumberg Posted January 9, 2006 Share Posted January 9, 2006 If your EA81 gets hot look at the ffollowig - Coolant Never use something with an insulating thing in it. Hard Water. I'm talking about calcium. Radiator Use as big as the factory used or bigger. Fan Follow what the factory did. When there is no fan surround high temps will result. Never change direction with out testing. Thermostat Whenever the thermostat is removed a very differant heat load will be put on the system. Wheel Don't try to reinvent the wheel!

TomRhere Posted January 10, 2006 Share Posted January 10, 2006 As mentioned, I would look at ways to isolate the air flow to the radiator. The way it looks now, you're drawing air that's been heated by the engine and muffler. You want to get as much cool air as possible. Once the engine starts to overheat, you're just adding more heat to the radiator with the way the air flow is now. Just my .02.... Link to comment Share on other sites More sharing options...
