GGB mufflers on N/A motors
I put a pair of mufflers on my naturally aspirated 600cu in. 750/hp motors and it wiped 15mph off my top speed ! Is the fact that these motors are N/A and need to breath the issue? I figured i'd lose a few mph but nowhere near this much. As you can figure the mufflers are coming OUT tomorrow. Anybody else have any experience with this? BTW they are Stellings dry exhaust.

Wow ,I had exactly the opposite experience. My boat goes no faster or slower with them on (5" tails on stainless marine 3's with water added right at tip as it enters the muffler),Smitty

I have GGB extremes on my NA 540, 680 hp, running full dry CMI's. I noticed no speed loss at all. Unfortunetly, as far as I know, GGB is out of business.
