i'm wondering if i should be running my eng. temp a bit higher. what do you run yours at?
I run mine a t 180 I used too run alot hotter and somebody thought that maybe the higher temp was ruining my transmission . I went thru 2 bfore I switched
why would engine temp affect tranny temp? what temp were you running it at. mine is about 180* right now, i'm thinking maybe 210 will burn fuel more efficiently?
I think stock is a 185 or 195 Thermostat.
210 Burn up your engine efficiently is more likely
why would 210 burn up your engine efficiency?
He said efficiently, that was sarcasm
Actually if you seperate the tranny cooler from the engine and you can guarantee you keep the engine temp at 210 to no more than 220, you should be OK and yes get more efficiency, but down here in the summer that would be a chalenge.
The newer cars actually do run closer to the 200 mark for that reason.
And to do more, you need to understand more of the thermodynamics:
The bigger the difference in temp between the combuston chamber and the outlet at the tip of your exhaust, the better the efficiency, so if you can also reduce the temp of your exhaust gasses, you will be in better shape.
I always thought about making some water cooling mufflers, the water would definitely muffle vibrations and would cool the exhaust gas.
I used to run it at 200 and then sometimes it would hit 210 . Somebody told me he thought that was heating the tranny fluid up also and maybe thats why I lost a few transmissions ? Go figure
Mine has a 195* thermostat. Most cars runs that ove here since the temperatures can get pretty low in the wintertime.
maybe i'll try a 195* thermostat, and keep the 185* stat on hand. altho, i can't imagine 10* could make that much of a difference... could it?
