Not yet!!!! But it’s going in my ‘74 W200 with a slow shifting NP435 :/.

Engine was on the dyno today, 510HP /508 FT LBS TQ using a 3.48” diameter upper pulley. That’s 72% overdriven. Apparently the blower wasn’t making any boost at all, the rotors were in the way, holding the engine back.
Next try is with the 2.5” pulley. Brian thinks that should make some boost, good for around 40 HP.
Stay tuned, maybe Friday I’ll have the updated numbers.
