The density altitude was high that day (around 80 degrees at Big Willow which is 2,300 ft above sea level) so the turbos certainly helped me on this run.
I was really close to pulling the trigger on a 5.0/BOSS but upon reading on their Chinese made manual transmission with lots of horrible stories I looked elsewhere. Lots of owners complain of broken transmissions and AFAIK there isn't a solution from Ford yet, hopefully somebody can prove me wrong.
It really is too bad as at the time I was massively itching for a v8 RWD manual coupe that is affordable and can be easily modified. The Coyote engine is awesome but without a reliable transmission to put that power to the ground (and auto wasn't an option for me) it was a major deal breaker.
