This Should get your car from Room Temp to 180 in about 4.5 mins no need to block rad off helps keep engine up to temp under caution and burns less fuel to keep engine warm. In staging I do not run engine at all. Start car with 1 lap to go then pull out to track up to temp Less fuel burn off Less time on engine running
