im bad with the Race Gas prices. i cant remember from the top of my head. I'll check when I get to the shop tomorrow.

we stock VP103, C14+, C16 and Methanol. Price range is about $35-60 for 5 gal pails. i think there was a post i did awhile back with the prices.

LOL, 13.5:1 is pretty high bro. I think anything over 103 octane should be fine with no pinging. I'm running 13:1 CR with 100 octane and my car runs smooth, so check experiment with different octanes.

Depends on how much advanced ignition timing your running.
