93 octaine in n/a
#12
they are similar, both are problems of the fuel igniting earlier than desired. dieselling happens during the compression stroke, and the other one happens during the intake. The different configurations of the engines determine how they will react

Dont ask me why, but the few people I know that REALLY know these cars all say that they make more power on 87 octane. One guy dynoed with 87 and then with 93 and lost 12hp. Granted he may not have lost any power if the timing was advanced more but i cant see that you would gain much either.

changing the timing will make the motor run like ****, i've tried it a million times on a dynojet. I got about 3hp out of a few degrees more advance, but the motor was soft and peaky above 7k rpm.
use 89 octane and stock timing at the drag strip, and 87 when cruising around
