    It’s e-CVT gears, the lower ones during city driving, anything over 2200 RPM is redlining.

    This mod will make no difference to performance or mpg. As stated earlier...and it's well documented...cleaning out the intake because of the egr would better suit your efforts.

    o_Oo_Oo_Oo_O How much is the price of rice in china??????

    Air from OUTSIDE the engine bay is drawn in by the wipers(front), NOT the engine bay?
    Since the compressor is ELECTRIC, the engine is not effected if the engine is not effected
    whether the compressor is on or off.
    Clearly you have no idea how the ac system works. Or how air flow in the engine bay works.
    It flow down and under the car.

    Air for the engine is drawn in from the FRONT of the car, before it gets into the engine bay.
    The duct work is also in the front, then into the intake manifold. Cooler outside air hits this
    above the condenser and radiator.

    Guess you don't understand thermo dynamics either.

    It's kinda scary to think of where you are getting these ideas! :eek::eek::barefoot::barefoot:(n)(n)

    If you want to devote some time to the car, reduce the risk of overheating, I'd look into EGR cleaning, and water pump replacement. Oil catch cans are a nice rabbit-hole too.

    Not this soon in the cars life, also I’d remove that insulation you put on the sides of your bonnets during summer months, it increases heat soak when the ICE is not running at a stop light.

    Don’t care, high RPM is high RPM. The engine does best when kept in the 1800-2200 RPM range.

    No clue what you’re rambling about, my scan gauge shows huge differences in coolant temp when my cabin air is set to HI (hottest), no AC, no recirc before turning the fan to OFF compared to setting it to LO, AC on, recirc on before setting the fan to OFF.

    You don’t understand how to exhaust engine bay heat through cabin air settings. Keep driving with the recirc on like a dumbass.

    It sounds like you're jumping through a lot of hoops to make a thermometer read one number instead of another, all while the engine can operate fine-for-life at either number and all the ones between them.

    Test it yourself if you have a scan gauge that shows the water coolant temp, notice the coolant runs hotter 190-197 degrees during “higher rpm” accelerations when any of these settings are on:

    AC
    Recirc
    LO temp (cold setting)

    compared to having them all off and setting the cabin air to feet and windshield.

    If I can keep temps slightly lower, then there is no harm, the material for both the tinfoil bubble wrap and heat resistant wrap is $50 and enough to wrap two intakes.

    While I don't know how your using cabin air to exhaust engine bay heat - I do know that installing a hood scoop and intake snorkel will cool your engine bay and get cold air into your intake system.:censored::whistle:

    Now if someone would crack the ecu so we could eliminate the egr all together...I would be very interested.

    This thread is pretty amusing. I needed a good laugh today, and this thread has delivered.

    Yes where do I get an intake scoop for the gen 3 Prius? That was in the OP.

    I’ve tested it with my scan gauge, leaving the cabin air settings to HI (hottest temp), AC off, recirculate off and feet and windshield position air flow before pressing off on the fan button helps exhaust engine bay heat as you can still literally feel the engine bay heat exhausting through the windshield and feet vents with the fan off through your feet if you don’t mind driving with windows open. Compared to all of those settings to ON and “LO” (coldest temp setting) the coolant reads a lot higher in temp compared to having all those settings to off and “HI”. I get an average of 188 degrees in coolant temp when all settings are off during stop light to stop light driving. When all are on and coldest setting is on I get 191 degrees average coolant temp and reaches 197 degrees on redline acceleration because it sits in a heat soak at a stop light with the engine off at 191 degrees already.

    I’m looking to decrease heat soaking, nothing for performance.
