Yes ... Mine are BK800 engines ... "Key Power" 800hp 12V71TI. It took a while to figure this out ... I was thinking mine were J&T or Covington versions of the 12V71TI ... finally figured it out. Stock 12V71TI power was 650hp. I believe that Florida Detroit Diesel Allison Jupiter FL now occupies that space of the old Key Power company. None of the old spec info on turbos, injectors is readily available and the original injectors aren't made anymore anyways. Mine has the 9215P injectors Part# R5229715P and the R5101513 Turbos ... I think the combination results in around 800hp. Heavy and slow compared to a pair of C18 CATS but of course much much less expensive.
