The ECO Boost car with a VERY mild tune sent a rod through the block at 6 months. Traded it for the V8 Coyote Roush we still have. Our V8 car Dyno'd recently at 803 HP at the wheels. So 450hp is a starting point with these Coyote engines and still have reliability.
The 24 Mustang is OK....ALL new chassis, related to the SUV line so Mustang can go AWD in 25, but I think we will keep our 2016. For the cost/HP ratio the new cars is costly!!!! Thanks
