Re: Merc 525 S/C Blowers
 

The 525SC blowers are way too small for 540ci engines. They'll fit, but they are too small.

Griff..even with a 1050CFM carb ???!!!

Re: Merc 525 S/C Blowers
 

Yes, too small. Carb size really has nothing to do with it. Besides that, a 1050 is stock on a 525sc which is 454ci. You would have spin the 177 at its max rpm--about 13000, just to make maybe 5lbs of boost on a 540ci engine. Spinning it that fast creates a ton of heat, reduces the density of the intake charge and can cause detonation.

your not helping me sell these ..!!!LOL :cool:

Re: Merc 525 S/C Blowers
 

How about changing the intake and bolting on a small block, and lowering the speed?

Re: Merc 525 S/C Blowers
 

The blowers would work great for small blocks. Probably too much carb.
