When the car is tuned well, the engine will be capable. When I did a 1/2 mile event (from a dig) on my stock block (mid-high 130s via datalog, best of 161 according to their trap :/) we ran the car for 3.5 days... Started on Friday evening with E30, 27-28psi making around 350whp and ended Monday morning on MS109, 34-36psi at an estimated 430-450whp (guesstimate via datalog) In total I did about 18 runs throughout those days in 80°+ weather. On Monday morning it took several kill tunes to put the engine down at 34-36psi. Keep in mind my car had been tuned since about 700 miles and was at 30k at that event. Stock turbo tuned, two versions of Cyborg, and then the 450r kit. Several hundred log pulls on that engine, mountain carving, other 1/2 mile races, road trips...
The Fiesta block is very capable.
