85-95mm Throttle body that will plug and play with Merc PCM555 ??
 

Is there a larger throttle body with the same electrics/features as the stock Merc 75mm TB on the 496HO that will work with the Merc PCM555 ECU right out of the box? Something in the 85mm-95mm range.

If not there a TB of this size that will accept the stock Merc TB electrics?

I wonldn't go to big, it's as much about air velociity as volume!

I should have mentioned that the larger TB would be inconcert with other changes that would result in ~525hp including high flow heads, hotter cam, ECU reprogram, etc.

I found an 80mm BBK1709, soon to be released as 85mm BBK17090 and comes with a smooth flow spacer to transition from the larger TB to the existing intake manifold opening ID. which BBK says will bolt up and accept the electrics from the stock unit. But the unit has the automotive version linkage lever on the throttle plate shaft which would have to be coverted.

Has anyone done this?
