Look At This Picture The CTR pistons are 10:1 ratio and the type S is a 11:1 ratio.....if the CTR is higher shouldnt the ratio be higher?????.....if there si an explanation will you please educate me.........[IMG][/IMG]

 

first of all, there is no ratio. second of all, if the releifs dive much deeper, it is possible to have a higher dome but lower compression. and why are you comparing a pct to a type s, when they're a completely different bore, with a completely different wrist pin placement?

Bore and stroke of the engine is also an important part of what determines the compression ratio of the engine, along with head cc, gasket thickness, piston dome and piston to deck height.

Shorter stroke, smaller bore (CTR) will need a bigger piston dome to make compression than a longer stroke, bigger bore (Type-S)
