Want to add whipples on 33' Donzi w/502s

Right now running approx 73 mph. What kind of speed increase
do you think I'll see?

Depending on your final HP, I would say 85-90mph easy.

Figure w/replacing stock exhaust manifolds w/headers, etc....I'll expect approx
650hp per motor....up from 420 stock. It's probably about all the bravo 1 drives
can handle

That should be a 90mph boat. You will need full hydraulic steering if you don't already have it. And those bravos will not last long, better start thinking XR or imco.

Mjbtx,

I have a 33 baja with 502's.
I purchased two side mounted whipples last year from Oso and never
put them on.
Let me know if you are interested. They were used 1 season from previous owner.
