I’m now in a 2018 Gen II Raptor. I previously had two 2013 Raptors, one was stock, one was a Roush Stage II with a smaller blower pulley. The Gen I Roush was likely making around 625hp (was 590, but I was running a 72mm blower pulley making 9.5-10psi at near sea level). My Gen II 3.5 TT with a tuner (E85 and 91), front mount race intercooler, ID1050cc injectors and Ford GT spec spark plugs is making right around 625 hp @20.7psi.
The Gen II is considerably quicker and faster than the Roush. It weighs nearly 800 less lbs and has significant mechanical advantage with the 10-speed. If I had my druthers, I’d have a Gen II (looks over time have grown on me, but still love the Gen I aesthetically too) with a 7.3 Godzilla or 5.0 Coyote. The TT 3.5 is surprisingly quick and powerful, but the sound it makes…ugh. Also, pushing 600+hp and 20+psi on a 3.5 V6, stress per cylinder is considerably higher than on a larger displacement V8. It’s held up great so far and no significant mechanical issues, though my timing cover is leaking oil, albeit not a lot, and I have some coolant leaking from inside of the valley between the intake runners and head.
I will say this. In the 15 months I have owned the Gen II, 13 of which have been modded, I have spent at least 20x more time at WOT than on my Gen I Roush, and I owned it nearly five years. Part of me was hesitant to drive it too hard knowing the 6.2 wasn’t designed for FI from Ford. Part of it also was due to being stranded three times when my serpentine belt would get shredded and/or my belt tensioner arm would completely shear off due some poor design and tuning from Roush. I can get into that more if needed, but I didn’t have the utmost peace of mind with the Roush. It sure did sound mean though. I miss that, greatly.
