Hey Brett, I have spoke with your shop a few times and am going to come over and do some testing on Big Green. I live in Fall River and have a 97 Crownline 225CCR with a 454 MAG with a Whipple, B1 spinning a 27P MP, spins to 5k and runs 65-67 average with 68.8 as a best. I know the slip is very high and I want to get quicker acceleration since most of the lake we use are short and I run out of lake quick. I have been looking at the REV4 and want to test what ever you think would help. My rev limiter will spin past 5400 and motor has upgraded valvtrain so it should spin it there no problem. I moved my stereo batteries to the very rear of the boat and so far has helped a ton with bow lift. looking to run low 70's and I think its doable with the power I have on tap. What is your thoughts on this setup??
