Couple of BOSS motors on the dyno this week.
BF XR8 260 with a Spoolinboost turbo kit, basic motor with rods, v/springs, h/studs and billet oil pump. 465kw@12psi on e85 limited by single 525 pump.
BA GT 290 with a set of GTHO cams in for a retune. Arrived on a towtruck with fouled plugs and no start. Tune was a complete s**t show with idle/cruise afrs in the 9s-10s! Tuned up nicely with 243kw through the 4k slippy converter and btr.
