Detonation/ p r e ignition
Anyone out there who has had problems with pinging while using an Edelbrock
sp2p intake?
Has this happened to you? As in; pinging after the installation of the SP2P but not before, and with no other changes?
Detonation is usually preceded by pre-ignition, which is precipitated by the temperature in the chamber, or a part of the chamber, or a part IN the chamber; being TOO hot for the fuel being used, which then cannot resist the tendency to self-ignite.
Your
possible solutions, in no particular order are;
a higher-octane fresh fuel or a reduction in
loading
reduced ignition timing or reduced cylinder pressure
colder sparkplugs
a richer AFR or, fresh cold air
a lower maximum coolant temperature
reduction of sharp edges in the combustion chambers, or
a better shaped/sized, smoother, cleaner, combustion chamber
The goal of these changes is to eliminate hotspots or to reduce the temperature; in the chamber, just prior to the ignition event.
If the SP2P replaced a 2bbl, then yes it is possible; this speaks to loading, and possibly to AFR
