[QUOTE="BlackNDecker, post: 12409599, member: 131894"] I haven't seen anyone increase compression yet either....but this is where we will see the biggest gains with this motor NA. E85 would help keep cylinder temps down...Sunoco is also a viable alternative since you can have this delivered directly to your house. We probably won't see many more extreme NA builds like yours (with high compression pistons) until these coyote powered cars start to outlive their powertrain warranties and become 2nd and 3rd owner cars. Re: overcammed... In my experience, "overcammed" occurs when the power curve is shifted rightward giving up significant midrange power. Likewise, an undercammed power curve would be shifted leftward and would top out too early. Here is an example of an overly cammed motor (red line): [IMG]http://image.hotrod.com/f/pitstop/hrdp_0912_cadillac_electronic_ignition/28264060+w794/hrdp_0912_03_+tech_q_and_a+dyno_test_chart.jpg[/IMG] Whereas a properly selected cam will yield gains throughout the powerband: [IMG]http://sphotos-a.xx.fbcdn.net/hphotos-ash3/556585_405109586219475_2118391414_n.jpg[/IMG] [/QUOTE]
