Umm... Dodge Viper RT-10??...
I'm not very impressed. I think an 8k redline is impossible as well. I don't think an engine can be very reliable, unless they seriosuly did tons of research. But I am still doubtful..
0-60 improvement of 0.5 s? I'd stick to the E39 then.
Did you realize that the RT-10 is 8.3 L, not 5L?
Easy to make 500 lbs. torque with that displacement.
8K redline is not out of BMW's tech pool.
They have done it successfully with the M3's S54, and have been proven reliable, other than some manuf. problems in a few build months early in its production.
Another thing you will find is that torque in a N/A engine is closely tied into it's displacement. This is why even with an extra pair of cylinders; the torque is similar with the same displacement.
All the V10 has allowed the engine to do is to make the pistons smaller. This has helped the engine reliably rev higher, thusly the 8500 RPM. That extra ~2000 rpm is what is producing the extra 100 HP.
