I just had a good conversation with a Procharger tech. Typically in a marine application they don't run the BOV due to the lower rpm's we're running. I'm at mid 5k on the rpm's. If I change my set up to get closer to 6500 rpm's then he suggested a BOV would be a necessary addition. If I were to install a BOV now he explained I would be a little sluggish to start and it would take longer to take off. When I have another $10k to buy the heads I want and completely change out and set back the intake, suction housing, shaft, inducer, impeller and oh yea this would be the time for a new gel coat then I'll take a close look at the BOV again.
I love the instant hit I get when I go WOT. The only time I cruise is the first 10 minutes to get the oil temp up. Then it's really slow, wide open for as long as I dare, about 6 to 10 seconds or so. I looked at the time on some video I did and I'm pretty much at max speed in 6 seconds. Then do it all over again and again and again and ...
I'll be at the river for the 21' jet boat extravaganza & race on the weekend of Oct 20. I'm going to break out my Cobra for the afternoon full up jet-o-vator run of about 8 to 10 boats. 5150 Whiteboy knows more about who will be there.
