Endyne didnt make them smooth like I said above they simply radiused the edges around the valve recesses and roughed up the surface of the dome a bit. This was all in an effort to reduce hot spotting yes but these are HUGE edges we are talking about when compared to the bowl surface.
Also I think youve got detonation mixed up. Youre thinking of pre-ignition which is caused by the mixture being set of by something other than the plug.
But back to the argument what do you mean by what you say is true then why doesnt everybody run 13:1 and 14:1 compression?
I havent said anything about people running high compression ratios or that people ONLY need a colder plug and higher octane fuel this whole debate started when you said that in order to combat detonation you need to smooth the bowls. Sure itll help but but like I initially said it is much more beneficial to SHAPE the bowls since the bowls arent in such HORRIBLE shape as to cause hotspotting. Detonation is an uncontrolled burning of the mixture resulting from end gases in the mixture igniting before the flame front has a chance to. This can be minimized by changing the combustion chamber shape and piston floors to promote a complete burn and one that occurs quickly enough not to allow end gas ignition.
I think youve lost track with all this back and forth of what this argument was originally about.

 

Yup forgive us if were not were not just sitting back asking which motor will fit in which chassis etc.

 

since I am not going all out race and this is a daily driven car that must last me throughout college if I use a compression ratio of some where between 11.3 and 11.5:1 just to be safe would I need a forged piston or could I get away with a factory cast one?

 

factory cast piston would work nicely. JDM itr pistons would come really close to 11.5:1. I dont have a calculator around so I cant give you a definite #.

 

so do you guys think 12.5:1 is too high for a sohc with Honda parts?? i heard it will run fine...

 

Two words.....NO FAKEDYN

 

so you have first hand experience dealing with what compression works on these hondas?
sit down

 

What in the world does that have to do with debating engine theory? As for my views Ive fixed enough seen enough and read enough to have a good idea of what Im talking about.
Stand up??

 

loooooong story which basically boils down to Larry telling a lot of lies and now having lost a lot of the following he used to have.
