Scott:


Actually, even though my POSDD was off, my bike was running too hot for my taste. Particularly in hot weather and traffic. I didn't always bend over backwards to read the POSDD but, I knew it was hot, so I took some measures:

- Wards fans
- 10 row Jagg oil cooler with fan

The above operate without thermostats and are wired in the aux circuit. I turn the fans on when the going is slow. Now, I can just turn them on when the oil guage climbs above 230... Or whatever.

Also, for the best protection against heat, I'm running Amsoil in the motor.

 

You have an air cooled engine without a factory installed fan, like your lawn mower has. Why would you even come up with this question? Your engine isn't cooling unless it's moving. It's going to get hotter the longer it idles, and the higher the ambient temperature.

 

===================================

" Your engine isn't cooling unless it's moving. It's going to get hotter the longer it idles, and the higher the ambient temperature. "

BINGO!/LOL!!!

Thats why i have stated mult times in mlt threads here in HDForums that HD's stock oil cooler is useless as ***** on a bull because when the oil cooler is needed most like when the bikes sitting still at stoplights or when in very slow moving traffic loafing along in 1st or 2nd gear inbetween being stopped there's is either Zero " 0 " /NADA/NO airflow going thru the oil cooler sitting at stoplights or so little airflow thru the oil for a few seconds while putting along with 1st or 2nd gear for 10-15 seconds before stopping & sitting still again it cant cool the oil like the ultracool oil cooler can with both its dual electric cooling fans wound up tight cranking away sucking/moving plenty of cooler air thru the oil cooler along with Wards dual elec cooling fans giving additional cooling to heads & upper cyl's @ the same time giving the heat HD motors generate in summer heat a " 1-2 knock out punch" !

This is one of the many reasons i installed Wards cooling fans (best targets cooling heads & upper cyl's) along with an Ultracool oil cooler with dual thermostatically controlled elec cooling fans (best targets cooling the oil which also reduces engine temp at the same time along with Wards cooling fans too) both at the same time as max effort cooling team for my HD that works great.

Those 2 cooling mods working together as a team reduced oil temp 50+ deg-F in summer heat resulting in multiple benefits/improvements in engine performance and overall riding experience on my 09 FLHTCU which i posted about earlier in this thread.

Happy Motoring!

=============

Ah,with the Wards fans ,oil cooler with cooling fans & amsoil you have a very good cooling team for your HD so you must have experienced some of the same great benefits/improvements like i did post installing the 2 cooling mods on my bike too.

But it's nice finally to see i am not only person here in HDforums that realized even though HD states 230deg or so oil temp is acceptable the truth is HD's air cooled v-twins perf better with oil temp in approx 195-200 deg range or so in same summer heat vs when oil temp is @ approx 230-240deg f or so in same cond thats still acceptable by HD & or most if not all oil mfg's too esp when running a quality Syn oil even though we know 1st hand the motor performs better in many ways when its cooled lowering oil & overall engine temp.

Happy Motoring!

Quit worrying about oil temps. Cool the oil all you want it will have no effect on the heads. Not enough oil flows to the heads to do much cooling . That is a pure fact. To think any different is just BS your self.
Heads can get over 300 degrees on a hot day. want real numbers ask I will post them for you.

 

===========================================

I AM NOT WORRYING ABOUT OIL TEMP,i just decided to do something to correct the negative affect excess heat generated by air cooled hd's has on the motor itself and the riders too which the avg HD toruing bike owner experiences when riding in summer heat.

Last time,i go by facts and the fact is i got every 1 of the improvements i listed below when i reduced oil temp reduced 50+ deg which shows the motor responded very well to the additional cooling you think isnt beneficial that in fact is.

And anyone that try's to argue that fact shows what little they know the know about how excess heat affects a lrg displacement air cooled HD motors in summer heat.

And the other fact is ONCE AGAIN YOUR JUST ANOTHER GUY HERE IN HD FORUMS THAT OBVIOUSLY DOESNT KNOW WHAT YOUR TALKING ABOUT WHEN IT COMES TO THE BENEFITS THE AIR COOLED HD MOTORS GET WHEN COOLING /REDUCING OIL TEMP 50+ DEG IN SUMMER HEAT LIKE I DID ON MY BIKE.

AND IT'S FUNNY YOU ARE SO OPPOSED TO IT WHEN YOU IN FACT NEVER TRIED & OR INSTALLED THE SAME 2 COOLING SYSTEM MODS I DID TO SEE IF IN FACT YOUR HD RESPONDED WELL TO IT OR NOT & SAY ITS NOT NEEDED WHICH MEANS YOU DONT THINK IT'S BENEFITIAL WHICH IS TOTALLY INCORRECT & NOT THE CASE,PEROID,END OF STORY!

HOW CAN YOU SAY THAT AFTER YOU READ ALL THE GREAT IMPROVEMENTS/BENEFITS THE MOTOR ON MY BIKE GOT WHEN COOLING THE OIL 50= DEG ON HOT SUMMER DAYS?

And you stated you thought the heads wouldnt see much temp reduction,well have to get some x-amount of temp reduction i am sure the heads got temp reduction because the oil cools the motor and the o9il itself was cooled 50+ deg which directly translates to motor being cooled x-amount at the same time,just how much i dont have pre-post data on.

But who does have some pre-post head/cyl cooling data data is the mfg of Wards twin elec cooling fans that are directed at the heads & upper cyls with the mfg having real time test data showing Wards fans do in fact reduce head/engine temp & thats without the oil cooler i am running with dual elec cooling fans that also cooled the oil 50+ deg on top of what the wards fans have already proven to do cooling wise,see the data in on wards fans website,the wards cooling fans & oil cooler with elec cooling fans working collectively together have proven to be a great cooling team.

Botton line is your completely misinformed on the subject because you never tried it using same exact 2 cooloing mods i did and have absolutely nothing to base your OPINION ON other then BS,as for me i have a 50deg+ redduction in oil temp along with all the multiple benefits i got cooling the oil & motor to improve what i say is fact,not BS from someone that never did it.

ANYONE THAT THINKS THE BELOW IMPROVEMENTS ARENT BENEFICIAL TO THE RIDER OR ARENT BENEFICIAL TO A LRG DISP AIR COOLED HD MOTOR ON A LRG HVY TOURING BIKE IS JUST BEING A STUBBORN YOU KNOW WHAT THAT DOESNT KNOW A GOOD THING WHEN THEY SEE IT POSTED IN FRONT OF THIEI EYES HERE NOT BELIEVING ANYTHING IF IT DOESN'T COME FROM THEM.

AS FOR ME I AM LOVI'N THE MULTIPLE IMPROVEMENTS MY HD GOT POST REDUCING OIL TEMP 50DEG + F IN SUMMER HEAT THAT ARE LISTED BELOW:

Scott

* OIL TEMP WAS REDUCED 50+ DEG PER STOCK HD OIL TEMP GAUGE.

* VALVETRAIN REMAINS QUIET WHEN MOTORS HOT.

* OIL PRESSURE WITHOUT COOLING MODS IN WARMER TEMP USED TO BE 8PSI @ IDLE & 32-35ISH @ CRUISE ON HOT DAYS,POST INSTALLING THE 2 COOLING MODS HOT OIL PRESSURE IS 18PSI+ & IS 45-48PSI @ CRUISE.

* MOTOR STOPPED DETONATING ON HD'S REC 91 OCTANE FUEL FOR THE 9.2 COMPRESSION 96" MOTOR MY BIKE HAS.

* NOW THAT THE MOTOR & INTAKE RUNNING A BIT COOLER IT ALLOWS THE MOTOR TO RETAIN MORE OF THE PWR/TRQ & CRISP THROTTLE RESPONSE IT USED TO LOOSE WHEN IT GOT ALL HEAT SOAKED BEFORE I INSTALLED THE 2 COOLING MODS.

* MOTOR STARTS/TURNS OVER EASIER & FASTER LIKE POST FUELING UP ON A HOT DAY BECAUSE THE STARTER & BATTERY ARENT AS HEAT SOAKED ANYMORE.

* OIL RUNNING 50+ DEG COOLER MEANS LESS HEAT IS HITTING THE RIDER/S IMPROVING RIDER COMFORT LVL IN SUMMER HEAT TOO.

 

wscott,
Were you on roadstar clinic for a while? I ask because I remember the same long winded posts about every topic that came up. If I remember right, you were trying to convince everyone that Rotella T6 5W40 was the perfect oil for our "old school flat tappet engines". I also remember punctuation wasn't one of your strengths. I also remember if anyone questioned you, you went on and on. I don't have time to post multiple paragraphs about every topic that comes up. Please get out and ride.


If that wasn't you on roadstar clinic, my apologies.

 

Hey Scott, you got the Wards fans installed? I have a set but havent installed them yet... I have a 120R, it gets pretty warm.. I put on a Hi-cap oil pan already, havent decided whether to put the fans on yet... Im sure theyd be beneficial...but I did have one question though.... wont those fans just blow all the heat onto your right leg? legit query, as its already warm enough over that way from the exhaust.

 

That's a really good question, and one I've wondered about myself. I'm also wondering why all those cooling fans want to blow left side to right side. I mean, why not the other direction? Would that be less effective? Why not just put a much larger fan between the frame rail out front as if there were a radiator there, would that not better simulate forward motion?

I'm not just asking because I want to provoke anything, just trying some outside of the box thinking.

 

Holy crap wscott, relax brother or you are gonna blow a gasket...Wound kinda tight, I'd say...Everyone likes cool oil...really...i promise...relax...
