just wondering :
540 cu.in with dart heads + 10 lbs boost on top of it with optimum cam and carbs. how many hp it has to generate?!?
can it produce around 850hp?

Hey Timicun,
What kind of cam and what compression ratio are you running ? If I can broom my boat this spring I will start on another 540 for whatever new boat I end up with. I plan on supercharging and also want to make around 850hp.

planning to build engines : just an idea for the moment. dont have the chargers or cam but perhaps will be around:
comp. around 8:1
cam around: @.050....240 , 632 lifts in/ex.
superchiller
msd boost retarder box for safety
our octane around :90 ( dunno if there are different standarts for this.but our gas is not very cool)
what boost would you use with pump gas ?

Your like 13.5 to 1 CR with those numbers. Alltitude can change this but that is way to much CR for pump gas. I think I would build as big a cubic inch motor you can and then keep the boost low. Thats how engine builders make the big HP numbers and advertize running on 87 octane. What everyou do I would invest in some pyrometer gauges and knock sensors. Might save you some broken parts down the road. 850hp from a 540 does not need that much boost as the other posts have stated. As long as you have a set of good flowing heads.
Back4more what heads are you running?
