yeah I was kidding...everything I put into this was ultimately just for the revs...ARP bolts are basically holding every spinning part of the engine down...and nearly every bottom end journal has a sharper tolerance for lubrication to stay as good as possible...
TDC @ exhaust stroke is truely the only thing to worry about at high revs...as long as you have high real compression (by real I mean not the mathematical constant being "static"...overlap bleeds off compression into the exhaust system at some speeds due to scavaging...you can have very high "static" compression, but low "real" compression if your overlap settings are big...)...high compression allows a strong negative force to help with the TDC directional changes...the piston travels towards the head, and with high compression, the precombusted mixture will cause a retarding force that can actually put less stress on the internals even with very high rpm...but obviously only during TDC @ intake stroke...exhaust stroke there is nothing pushing back on the pistons when they hit TDC....and the calculations needed to determine how strong the rods, wrist pins, etc. need to be are directly based on the forces at this point of the engine cycle...as far as revs are concerned, this is the most stressful part of a 4 stroke engine's operation...
as far as SWC cars, I never knew...I was told they could not mess with bottom end dimensions...so rods had to be the same length, as well as stroke/bore...but compression could be increased...I do know though that they were also up around 8k rpm...with some wildly modified intake manifolds...
The proteges were pretty competetive too until RealTime was running the RSXs...I simply assumed they had to be above 220whp, not at bhp...but I could be off...
either way though...there is plenty of room to improve...if I ever get a real job, I will just tear everything apart again and put a 88mm destroke'd crank in it or something...and shoot for 9k...as far as I can tell more power will be tough to get without piston speed...at this point...
