Yes the extinguisher mount is Scott Drake. Got this one from CJ Pony Parts.
Bob it’s a good question, not sure of the extent that people are racing ecos without balance shafts. That said the more notable eco engine builders basically will not put balance shafts in their built blocks so hoping that they’ve tested it. Also Ford Performance sells a balance shaft delete block-off plate so I’m expecting they also tested it sufficiently. The block is basically a duratec from Mazda apparently and lots of guys there have been doing this for ~15yrs with good results. Fingers crossed!
The balance of the Ecoboost is good in my opinion. The engine is tuned for low end torque so it’s fun around town but not what I’d call a drivers motor. That said, my two main qualms are both fixable and then it should be good. One as mentioned is engine rotating mass. The other is power fall off between 5500-6500. A tune helped a good bit, but the turbo runs out of breath up top. A Borg Warner EFR turbo fixes that. They make around 400-425wtq at 3500rpm and hold it till redline.
