I agree. I also find a simpler pattern with my deep sump. When I shoot the gun at the oil temp guage I get a similar reading as the gauge. Then I'll shoot the bottom of the sump and it will be up to 20* cooler.
I have no basis for this but I also feel that heat exchangers act the same way. Just another way to remove heat and make your engine run at the proper temputure.

Also, thanks for the HD temp gun suggestion. I was looking for one that goes 800+ for exhaust component readings this summer. Couldn't find one that high for under $80 until I checked their website!

When I got home tonight I tested my transaxle temps. It was 180* at the engine joint, 140* at the axles and 110* at the nose cone.
My drive was 10 miles with a 7 mile 1200' climb from 6500' to 7700'. I took the climb at 65 to get the oil temp up to 200*. I will randomly check the temp to see if I find any differences. Hope this helps.

I heard somewhere else that WildCats had a problem, I thought it was handling. I will keep a close eye on them.
I want to get one of those infrared thermometers to measure Tire temps, and engine temps. I think there is a keychain model but the Fluke-62 Max Infrared Thermometer looks like it might be the best quality for an inexpensive hand held gun. But something like this would probably work Extech-IR100-Mini-Ir-Thermometer!

I think Wildcats might be the tires that shredded on someone Vanagon a few years back. Keep in eye on the for potential failures. |

After running those RPMs for a while pull over and use on inferred temp gun and you should get a pretty good idea. I'll try to remember to do that and get back.

I have not measured temps is but I would guess it stays below 150 or 160 degrees except for long hauls on a hot day at highway speeds then they probably hit 200'!
As far as the Hankooks go I just put them on the front, just the 185's and what a nice ride! love them. May go to 195's for the back but my Wildcats in the back are 27" in diameter and that helps the gearing a lot.

Does anyone in the San Francisco bay area know where I can get my hands on a transmission oil seal before Monday? Its the donut shaped one behind the CV joint on a 3 rib 002 transmission.
Thanks

+/- 24.5" with the tire installed, from ground to top of tire, with 32 psi. I can see 25"+ with an unmounted tire.
My ultimate goal is to stay 1 mph ahead of the long haul truckers, without turning more than 3400 rpm. Not sure what speed that is yet, maybe 67 mph?

What do you mean you tire is 24.5" under load? The load on a tire doesn't change its rolling diameter much at all. If under inflated you will get additional tread squirm with will make the tires spin a tiny bit faster at any given speed but this is corrected by running the correct air pressure for the load you are carrying.
A typical 205/70R14 has a diameter of 25.4".

I ran 205/75/R14 on my bus for a while. There is a major difference in the handling in the bus with C rated tires vs. The P rated tires you are running now. Not only the handling but I think you would be happy with the rpm drop and closer speed to your speedo. I would buy a set of 195R14 Hankook RAO8 tires, it will be a lot cheaper then a new transaxle. Our engines are similar and We have the same transaxles. I can tell you it was a major improvement in my bus when I went with the Hankooks.
I did run the P rated tires with my 2109 and my engine sounds a lot happier now.

Those are short tires, what size are you running? Are the C rated? My 195R14C Hankooks measure out to 26.3. At 70 on my speedo gps says 68. I bet a larger diameter tire will bring down your RPMs and make your speedo more accurate. Maybe randy in Manie will chime in, He seems to be the tire expert.

No tach just a oil temp gauge. I know my 195s are a larger diameter then the 185s that should be on my bus and lowers the RPMs a little but not as much as if I was running 27X8.5.
I had my builder install the oil temp gauge where the clock would go in the dash. He did such a nice clean job installing it that I felt bad asking him to remove it and put a tach there. One of my pet peeves is I don't like the look of the gauges hanging under the dash, I think it's ugly and they would block my parcel shelf. I'm thinking maybe the oil gauge under the radio like sicroccocrazy did on his bay/Acura build.
