More BS in post # 174 from Rat Bastid about comp ratio & alum heads. Must have an unlimited supply of BS.....
The engine masters episode said nothing of the sort about CR limits with alum heads, as claimed by RB. They tested an alum & iron head with the same 10.88 CR, & the alum head might have made 2-3 hp more, which is within the limits of dyno error. What is important is that they did NOT test CR limits for each head, by increasing CR until detonation occurred.
