TX Water & Oil Temp, NA 12a bridge port

What should my average water & oil temp.be on a 12a bridge port be? Also, what should be a warning of the temps.?

I installed a 12a into a 65' bug. So I don't have factory gauges. Going to buy gauges when I figure out the ranges.

As far as I know, oil should never go above 250 F, and you probably wanna see it somewhere around 220 F. Water should be kept between 160 F to 190 F, with 205 F being your warning temp.

My builder said to keep oil below 220.
My temps run around 185 water and 170 oil when cruising when stopped I noticed oil climbing up to 190. I am going to install a small electric fan to move some more air through the oil cooler when stopped in traffic. Or possibly switch to a water cooled oil cooler. He (builder) really stressed I need to keep oil temps down.

I am still breaking in my motor so I havent really wound it up yet so I cant say what it will do under heavy load.

Thanks for the info. My temps are staying @ 180water and 185oil. So, it looks like everything should be fine. Just not wanting to fry my rotor.

Don't bother with a air-water-oil cooler. It much more efficient to use an air-oil cooler than to use hot coolant to cool hot oil. When you do that the coolant absorbs the heat of the oil then has to be cooled even furthur by the radiator. You've sort of solved one problem, but now you have another. A small fan will do more good than changing the cooler type. Switching to an air-oil cooler I noticed a good decrease in my coolant temps, so there's one improvement.
