Wrong thread cowboy. Reason why it's so annoying to see a thread like that is because if you go to the search option and type in de vs. hr, your going to see more de vs hr threads than charlie sheen has done 8 ***** and they always turn into a **** fighting contest.

You completely lost me. What?

" Reportedly over 80% of the internal components were redesigned or strengthened to handle an increased RPM range sporting a lofty 7,500 rpm redline. A new dual-path intake (two air cleaners, throttle bodies, etc.) lowers intake tract restriction by 18 percent and new equal-length exhaust manifolds lead into mufflers that are 25 percent more free-flowing for all around better airflow. The electrically actuated variable valve timing on the exhaust cams to broaden the torque curve is new over the "DE" engine. The new engine block retained the same bore and stroke, but the connecting rods were lengthened and the block deck was raised by 8.4 mm to reduce piston side-loads. This modification, along with the use of larger crank bearings with main bearing caps reinforced by a rigid ladder-type main cap girdle to allow the engine reliably rev to 7500 rpm. With an increase in compression ratio from 10.3:1 to 10.6:1 these changes add 6 more horsepower (306 total + 3 hp ram air effect not measured by SAE testing = 309 hp). Peak torque is up 8 pound-feet from the older "DE" engine (260 vs. 268) and the torque curve is higher and flatter across most of the rpm range, and especially in the lower rpm range."
