Yes.
Eurocharged recommended not to exceed 6200 with these engines back in 2008. I haven't heard anything different from them since.
My 6 spd hits 6200 RPM and a touch over 90MPH in third gear. I swagged my estimate of the autostick from driving Crumpy's SRT(
don't tell her).
Both have had their RPM limiters removed from factory settings...about 5800 rpms.
