Oh yeah. Fully built head port &polish with type r cams from a b16. Pauter rods, je pistons all arp studs and bolts , hondata s300 with eprom tuned greddy boost controlers tidal blowoff valve. It will be built very strong but i will probabaly break it in without turbo and slowly increase boost. That iws why i am gonna have laskey racing sleeve it so the sleeves will be good for 55psi which my final cr will be like 20 to 1 without turbo it will be like 9 to 1.

 

wtf? you have much reading ahead of you.

 

HAHAHA 20:1....get to studying

 

I have no idea what you are talking about a turbo ups your compression ratio and the way all the formulas come out the final compression ratio is like 20 to 1 at full boost but my math could be wrong i have screwed it up in the past lol. All a turbo does is force air into the engine upping the atmosphere pressure which in turn ups you finalcr at full boost depending on how much boost you plan to run for your horsepower desires.

 

Oh and i didnt mean i was gonna run 55psi that would be fuckin crazy. That is just what the sleeves are built to hold.

are you using that formula?

b= bore
s= stroke
v= volume of cylinder headgasket inclued...

where does the amount of air comming in affect that?

 

Oh i was using some other formula where you put your cr into it then you ad the boost into it. That would explain the odd faces.lol

 

no thats the correct one... turbos only shove more air into the cyllinder.... its compressed... causing a bigger explosion and a stronger downward force on the rod to the crank...

 

this one? http://www.zealautowerks.com/

 

seems like the static compression ratio stays the same and that is the one I believe to be the "true" ratio that is looked at... I think that the effective compression ratio is what it feels like or is relative to the power made... but don't quote me
