Do I need to start with a low boots # to get the fdr, and then add more boots, to get the motor up to temp?
The boost has to match the FDR. Low boost numbers (2-4) will require you to gear higher (5.6 to 6.0). Higher boost numbers (5+) will require lower gearing (6.0 to 7.2). It's a balance that you'll have to play with between how much of an RPM range suits your track conditions and driving style.

Temp is more of a maximum number that you're comfortable with for the engine brand you have. I'd recommend a motor fan to keep the temp in check. The smaller 3Racing style fans work ok, but the large LRP fan is best if you want to push it more.
