I also find it funny that with a peak displacement of 7.0l they could only muster 30 more hp than my hemi......could you imagine what a 7.0l hemi would lay down for numbers?? Just saying......
Like I said before, people think that just because it has an effective displacement of 7.0L at full boost(2,500 rpm) then it has it has it throughout its entire engine speed. That is not the case as it looses effective displacement as the rpms rise. An effective displacement of 7.0L basically means at 2,500 rpm the turbos is cramming 7.0L worth of air into the 3.5L cylinders making 420 lb-ft which can only be done with a big N/A 7.0L motor at this rpm. If you do the math, that means the 3.5L EB is making 199 hp at 2,500 rpm. By the time it reaches peak horsepower of 365 hp at 5,600 rpm, it has lost some of its effective displacement essentially making it smaller than a 7.0L. Doing the math here, the 3.5L EB is making 342 lb-ft of torque at 5,600 rpm.
