Controversial question - I hope! Is there a better type of cylinder head than an Ally 9E to use on my Mag engined trials car. Phoenix crank, Pigsty trials cam and indeed built by them about 12 years ago. I get about 125 psi and 30 bhp now,not sure how that calculates as a compression ratio?
I was thinking of changing to a new Ricardo one, will there be any more power for my money?
