2011 103" Street Glide w/255's Runs at ~275*. Too Hot, or Just Right?
« on: Monday, June 13, 2011. 04:55:40 PM. »
2011 103" Street Glide with the following mods:

Stage I intake
SE255 cams
Fuel Moto head pipe (no cat)
Rinehart 4" slip-ons
HD oil cooler
Fresh Amsoil 20/50

With ambient air temps at ~80*, the above rig will run at ~240*-275*, when on the highway and in city traffic, respectively.

I have nothing to compare these numbers to, except my 2007 96" Softail, which never gets above 230*.

Do the 103's naturally run hotter than the 96's?

Are the new 255 cams causing these numbers, or are these just average temps for this bike?

Thanks

Has the bike been tuned, or just a download? If a download, which one? The 103 "legal" stage 2 download is designed for 103 flat tops, 255 cams, SEAC and stock mufflers. Oh, and to keep the EPA happy.

After I installed the 255 cams, bike got a TTS 'canned' download to match the build.

I have since done nine V-Tune runs, and the VE tables look picture perfect.

Didn't notice any temp difference in between these two adjustments.

Need any other info?

Thanks

You might post up your MT8 file in the Tuning section for the guys to look at. It's easy to overlook something. I have a 37 cam in my 2011 RG Ultra 103 and I'm slowly picking off items that reduce the temps.
I feel the need... for twisties with speed.

TTS Tuning file: DUH-009-03-A0

Does this help?

Not really. If you did that many vtunes, your file would be quite different

Are you measuring the temps using the same thermometer for both bikes? That would be where I start.
You have 2 different bikes, and the temps are probably not going to be the same .
You are really not that far off the normal, given the ambient, and other details.
A good tune can drop temps a degree or two, if you find that right tuner!
My 103 with similar conditions shows from 215 -250 normally.
This is using a Marshall gauge with sending unit in the oil pan.
(My '09 seemed to run pretty warm also, but, I never put an oil cooler on it.)
I also have a dipstick digital gauge that typically reads about 10-15 degrees higher.

The 103" Street Glide measure oil temps using a HD dash-mount oil gauge (with sending unit in the pan) and a digital dipstick, which typically reads 25-30* higher than the dash gauge.

The 96" Softail uses a completely different analog oil gauge dipstick.

So, I can only expect my temp to drop 1-2* with a good Dyno tune? That's disappointing......

 I would Strongly suggest a Good Full synthetic oil.. Redline 20/50 or 20/60 comes to mind...

That Top temp. worries me..

The smart ones will help solve your problem.. Using the the good oil will Help..

Amsoil 20/50 isn't good oil?

I'm running as follows, cylinder head temp:

Interstate cool day: 235 - 240
Interstate warm day: 260
Around town not sitting in traffic 270 -280
Sitting a lot in traffic I will spike 300 and as much as 316.

Oil temp I have no idea.

....

Depends on who does your tuning...and what system they use. Too many variables to actually zoom in on a set number, IMHO.
My last 2 bikes showed significant drops in temps, but, not the same as they were different builds. My old 113 runs way cooler than the 2010, for example!

You may also be at the limit of  the oil cooler. My 2010 Trike last year was 103 with SE255 cams, Fuelmoto Jackpot head pipe, SE Ventilator air cleaner, SE 50 state legal mufflers, tuned with a SEPST. I pulled the HD oil cooler and replaced it with a 10 row Jagg and never got above 245 deg in 95 deg ambient, the 245 happened while caught in a traffic jam. Normally it would run all day long at 230, this is with the HD in dash temp gauge with sender in oil pan.

mine runs 225-240 closed loop 14.3 cruise. when I ran open loop and set cruise to 14.0 it hit 215. Put in Vrod plugs.

My 2006 117" will hit 220 on a 100 degree day with no oil cooler and my 1996 FXDWG stroker 96 never gets too hot.

275 is fine.....

if you run too cold (and some do) you wear metal faster (pistons, cylinder walls, bushings)

Sitting a lot in traffic I will spike 300 and as much as 316.

Oil temp I have no idea.

Mine is an '07 96" with 255 cams, and my oil temps will hit 230° 2-3 times every summer, usually staying around 205-210° on the fairing-mounted OTG when moving >45mph in the present 95° weather we've been having.  In the same conditions, CHT stays around 225-235° >45mph, moving around town 240-250°, and it rarely exceeds 280° even in summer traffic.  I have seen it spike to 300° or a bit higher a few times in two summers, but only in gridlock traffic.  I'm also running stoich (14.6:1) in the cruise range, but when switching between this and a richer map on the fly with the PCV-AT the CHT would decrease little, maybe 5-7°.  I now have the Power Vision, so I can no longer toggle between maps while riding.  I also have lowers installed but I saw no difference before and after.

If you are reading temperature with the HD information it is not CHT, it is engine temperature. While the sensor is mounted in the front head on a Big Twin it is way out by the cooling fins and will typically read 30 - 50 degrees cooler than CHT.

95-100 degree heat. 75 miles at 75-80. Oil temp never got above 200.. It's got a 6 row jag (hd version) oil cooler on it.. Downtown Palm springs, oil not higher than 210.. Traffic was light tho..

I wonder if I should pull the Harley oil cooler cover off the oil cooler and see if my temps drop a bit. Of course my cylinder head temp could be because I'm running a 103 with slightly bumped compression.

I should add that this is a 103, 10 to 1 cr, Syke heads, Trapped Road rage, Tmax, and 30 t front pulley,, 2007 EGC with the pizza box removed.. Oil temp taken with the HD sensor on the pan. From what I see, the oil temps track about 80 deg less than the head temps.. Head temps were measured with a thermocouple at the compression release next to the sparkplug and compared to oil at the filter..  I've not had a chance to thermocouple the EGC yet tho..
