Winter Warm Up - Oil Cooler Rad Blocking
Been a while since I posted anything, my rx8 has been running great i just love this car its so amazing, but its time for another winter.
From my experience last winter I find the rotary engine takes longer then I like to warm up and I remember reading that some people like to block their oil cooler rads with something like cardboard to help the engine warm up faster
Does anybody see a problem in doing this?

Takes a good 8 minutes for it to get to operating temp and make any heat, I just want to speed the process up a little. Our average winter day here in london ontario is -15C, cant stand it

The warm air coming out of the vents is a result of heat exchanged from the coolant. From my experience, the water temps increases at a rate comparable to that of any other car I've owned. However, the oil temp does take a significant amount of additional time to reach normal operating temperature (180 F) - but this doesn't impede my ability to get hot air out of the vents.
Perhaps a closer inspection of the heater core is warranted?

our heater core / expander / multiplier / whatever is pure cr@p. Many of us suffer from cold winters. I have to get my water temp in the 180+ range to produce any reasonable heat out my vents and then that's only through one side.
In spring / summer 180F water temp is no problem at all... but in the winter when it's cold out it gives me a good excuse to run her hard.

In my experience the oil temps on the RX-8 drop significantly with low ambient temps when cruising on the highway.
For example, on a 5 degree Celsius day at 100km/hr my car holds 72 Celsius oil temp with 85C water temp.
The thermostats in the oil coolers do not have any impact in this realm because they are already fully in bypass but the airflow is still cooling the rads and the hoses enough to impact the oil temp.
Get an oil temperature gauge and block enough airflow to achieve oil temps over 80 Celsius till the weather warms up.
