Compression ratio vs engine speed?

Just stop feeding the troll wi50. Maybe he will go away....

 For those with curiosity a link to the results. As usual the facts came pretty straight from Marty and Pank is FOS for the most part.

Compression makes power up to 17.1 as general motors engineering studies show . makes peak torque at lower rpm and hp across entire curve . Taylor and Taylor says in their book that flame propagation and rpm are proportional . Timing one by ear and looking at ignition timing with light to see where it is gets this topic squashed nothing really to it that correct ignition timing doesn't cure . This is also as Taylor wrote why ignition timing can be all in and even locked at a low rpm and still be correct for higher rpm . Hudsonater was the one if WiFi goes back to his post and reads that said piston could out run flame propogation which is not right with correct ignition timing . Taylor also said in his book that to low a compression at a high rpm imparts severe inertia and kinetic energy on the rod as it is going from btdc to tdc resulting in lower half rod bearing damage from the lack of compression canceling out the inertia and allowing top halve of rod to move away from crank journal the amount of clearance it was originally built with and increasing clearance with each stroke as rod bolts stretch or rod halve eggs . In Taylors book there is a formula to figure the connecting rods inertia and correct this issue by knowing you have enough compression to cancel out the rods inertia . Great book but does shed light on who's fos as butch says .

I could swear you have less than a basic 5th grade education. Now go show us where I said that......you are making things up again. However, I did make the statement that you don't want the "bomb to outrun the piston" which if I dumb it down for you would mean.....well I can't dumb it down enough, you'll only get it backwards.

It's nice to know though that we can now build all engines at 17 to 1 and don't need any ignition advance or retard. Do it to prove us wrong and let us know how well it works for you.

Pankey 2010 engine shown no signs of detonation something I guess you've had problems with and are hung up on and why your guys can't seam to get a handle on ignition timing .
