high ambient temps and pinging

[ff6849]

Will outside air temp affect/cause pinging under heavy acceleration? 

I recently got the car running this January, it has been running quite well. But the other day while driving its pinging  under acceleration, it seemed worst when with the A/C on too. The outside temp was well over 100'  (welcomed  to the desert southwest, but I will be cursing all winter long  just trying to survive June-August).  Will the high ambient temps cause this situation, I am running premium fuel 91-92 octane.

yes, particularly if the coolant temp is way up there

using a cold air inlet to the carb can help reduce temps inside the engine .

yep, forgot to specify that hot air, while less dense which makes the engine richer, is easier to ignite so a cool air system helps a lot

what options are available for cold air systems for a 73 'Cuda

[Chryco Psycho]

Build you own , dryer tubing hood scoops opened , any airflow possible through the engine compartment helps

[msbaugh]

Has anyone on here ever made the scoops on their e-body functional for that purpose? Seems like a cool project! I would love to see it

[msbaugh]

this is the most effective way to get cold air 

[Chryco Psycho]

Sure Cardboard should be effective 
 The most efficient place is a front air dam AAR/TA style or the base of the windshield / Nascar style , using dams around the car helps as well creating a vacuum under the which helps both aerodynamically & pulling heat out of the engine compartment from below .

if pinging, use high octane gas, dial back timing a few degrees, aluminum radiator
will keep engine cooler, lower thermostat.
