Re: Pinging after 40-45 mins of driving?

Yea you definately need to run 4 to 5 gallons of race fuel per tank. According to the chart I looked at 11:1 compression needs atleast 96 octane and 12:1 needs
atleast 100 octane, so you should try to get between them.

How much does it cost there? Costs me $10 a gallon at the pump. Trying to get it wholesale though.
