Like I said before, 8000 RPM is not safe on any 4G64 IMO. The stock rev limiter is set low for a reason. It's a shame really, but rod ratio is a bitch.Quote:

How long did I spend explaining to you why this is a stupid idea? When will you learn to listen? :roll:Quote:

AMS and a few others recommends a rev limit of 8500 for their 2.4l kits this is do to the rod ratio being changed i think they use a 156mm rod vs the 150mm stock...Quote:

bore: 86.5mm (stock)
stroke: 100mm (stroke is dictated by crank)
deck height: 6mm
cross sectional area of piston: ~5877mm^2
overall displacement: ~2.35L
rod length: 150mm (most of the time)
rod/stroke ratio: 1.5:1
piston speed:
100mm stroke at 7200rpm is 24.0 m/s
100mm stroke at 7500rpm is 25.0 m/s
100mm stroke at 7800rpm is 26.0 m/s
you most likely dont want to go over 26m/s without some custom hardware
when you start adding 200 hp to a car that was only meant to handle 100 hp, you start breaking other things like axles, trannys, etc.
lol im fing with you lol i knew you were going to say somethingQuote:

i'm at 87.5mm on my build
thast becasue you honed your engine
what kind of pistons?
wiseco high compression 11.5:1
Overbore != hone :roll:Quote:

Come on, now you just sound like an asshole.... :roll:Quote:

LOL, have fun making a square piston "ring." :lol:Quote:

lol yeah how am i gona figure that math out 0.0 to great for my mind!! :shock:
To get the greatest efficiency out of a combustion such as what happens to make your engine run, it has been proven time and time again that round is the most efficient.
