Any of you who have switched from a 52 to a 58mm BBk TB notice much difference?? probably just better throttle response is what im guessing. My buddy parted his motor off and gave me the 58mm BBK TB off it.

Useful for feeding a stroker with a decent cam assuming the intake is ported to accept it.

When I converted from 52mm to 58mm I noticed 1-2 KPA less drop in the MAP at WOT while logging with Datamaster. If you use the internet rule for KPA loss to HP loss, I may have gained around 4HP. In other words practically nothing.

I swapped on one only because it was a good deal and polished. Probably more trouble than it's worth honestly and basically no gain except in an engine making over 500hp.
