Oil cooler and high volume pump gears

[scotty]

Once I get a new hose for mine, I am putting mine back on.
While I was in Florida, in November, no less, I got stuck in some pretty bad traffic.
Big surprise 8O 8O .yeah right
Sat and watched the needle keep rising.
Sprang a leak I have yet to fix.
I would definately go with the cooler 8)

Doug you and i run almost the same bike and i never saw the thing go over 250 in heavy traffic. --With the cooler, The stupid thing almost never warmed up. I would have to ride for an hour and barely get the thing over 200
I wonder why there are so many diferences. Could it be the way we all use the throttle. I drive like a pusseycat except when in a drag race.
BTW We have ridden in florida twice so far. ((who you calling a slowpoke??))

install the cooler. why do you need the high volume pump? i'm fairly sure that they are for low rpm engines or engines that idle a lot, just to insure proper oiling to the valve train. also apprantly they rob top end horsepower. i'd like to here more about this ,you know the pros and cons.

I don't know Scotty, last time I had to keep looking in the mirror for a Buell's headlight 8O 8O 8O 8O 8O 8O :x :x :P :P :P :P :P
let's see the bite on this one

p.s. ALWAYS TRUST SCOTTY.
unless it's about some cheese story

Tim, Don't I lose my pressure light when I use that adapter? That's no good.

Hey Jethro, you're hurting my feelings mate, I wouldn't make a substandard adapter that didn't incorporate your standard oil pressure switch! Hell, I even offer an optional oil temp sensor in mine, unlike the "professionals", much more expensive adapters, ha ha!

Have a look at the pics on my webpage of my 6061 T6 machined billet adapters, not crappy cast "pot metal" adapters that everyone else makes!
Cheers, Terry. :twisted: http://members.optusnet.com.au/~sher...k/gallery.html

The Buell handles well and is a match for most bikes in the twisties but not with me at the controls.
If you think I'm going to try and defend how fast the bike is. Well don't forget that i am a gs rider just like you are.
When i ride with someone((seriously)) I avoid doing anything that looks like a challenge--Well except when i ride with big daddy
One other thought is that you have been riding in that mountain twisty country. I would be frightened to death by it.
I remember caliornia and my Vello in the mountains--YEEEEH

I'm installing an 1150 cooler and stock lines on my son's '80 1100 now. I had to fab some brackets for it to fit as the frame mounts didn't match with the cooler. Now that it's mounted it looks to sit a bit low - behind the front fender. I would have liked it up a bit, but the stock lines won't allow it. So - I may fit some custom lines and fab new brackets.

[Jethro]

Yeah, mine is a little behind the fender, but I figure the air is gonna be whipping around there anyway. I'm more worried about my exhaust header not cooling right with a big oil cooler in front of it.

Heck with the high volume pump gears. I'm just running it as is and see what happens.

Steve when i made my oil cooler and brackets, I uses automatic transmission fluid flexible hoses and clamps. It worked OK. I mounted the cooler higher to get better air flow and more cooling The problem that i then faced was that the high volume oil pump gears Were pumping too fast and the oil needed more time to cool so I installed a valve.
I was about to just drop a short stud into the elbow of the return in place of the seeping valve line when i went back to a stock system. iT WAS FUN

Jethro,
No you will not loose the light. Terry's adaptor is absolutely perfect. It was tight to install the first one, but on the second one I did it was a breeze because I had the Carbs off to rejet.

AS FAR AS why the temps are so different, I would venture to guess that we all run at different levels of "Richness" (cooler) and "Leaness" (HOTTER)

Scotty, I thought about this a little when I put in the gears last year.......I figured the oil would make 30% more passes through the cooler (in a given time) with the hi-vol gears, compared to stock gears....so I thought it might be beneficial, no? I have yet to install the cooler .....hope to throw it on before this season. I did notice the bike seems to run a little cooler with just the hi-vol gear mod though (not sure if I am imagining this) :roll: .

I think it makes sense. The business of not alowing the oil enough time to be cooled off because it was flowing too fast through the cooler is basic thermodynamics i think.If you encounter this problem, just restrict the flow somehow. The best would be one of those in line thermostats. I think Hap has one on his bike

Even if the oil is moving faster through the cooler, it is also moving faster through the rest of the engine and not heating up as much.

[Mr. Jiggles]

But using this line of reasoning wouldn't you expect that the slower you're moving through the air the better your engine and oil cooler would be??

Not really. What he is saying is theoretically correct. The ratio of the amount of time the oil is in the cooler to the time the oil is in the engine is the same (we call that the duty cycle in electronics), the frequency has changed is all. Mathematically speaking - the average temperature will not change.

Now, if the dynamics of the cooler change (size, efficiency, air flow, etc.) then the temperature of the oil will change.
