Re: Hi compression SBC
I am running a progressive kit with a 12gph nozzel on a NA small block with 49cc dart ground to 46-47 cc iron heads (13:1) stock 87 tpi cam with sucesses with 87 octane fuel. The trick is I am running -15% in the fuel enrichment table opossed to the stock +20%
I have chosen 100% methanol as the mixture and roughly 1/2 the total fuel is methanol under load.
Power difference is little if any over the 9.3 :1 engine that it replaced so far. It pinged on 94 octane in the summer. But it was the fith season and it was dialed. This is the secound season on this engine still debugging.
