CMI or not to CMI
 

The mills are out so the heads can be cleaned up on my 98 38 with Hp500's. Now would be the time to bolt up some CMI's . . . any of you Fountain kids made this leap? If so, do you think it was worth the dosh? They are super shinetastic!!!! Thanks for the input.

Did the "E" tubes on my Velocity on the 525 SCs years back and they were worth the change just for the look, and were good for a little as well. The current one has the 525s and the CMI tubes, just love to polish them up, and just take in the shine!!! We spend a lot of stupid money on these toys, just do it!!! Flitz metal polish is the ticket to a "Shinestastic" smile that just won't go away. :D

cmi or not
 

hi ive got a 27 fever 496 mag ho ive just fitted cmi sport tubes yes they look and sound great massive mid range improvement but dont seem any better wfo th e boat would run 70 both ways before not much fuel and only me on board now with 2 people 125 lts fuel still 70 maybe it needs more pitch at present l/h b1 26 at 5300 on tach the way tey go on about them i expected to se more improvement

cmi's look great, love em on my boat.

Go for it! Call Bill at Ateco for the best deal.

I would try a larger prop. From what I've heard the 496s work better if you load them and turn them closer to 5000 rpm, might see the speed come up a few then.

Pull the trigger on the CMI's..... the looks alone, at the docks, are worth it. :drink: not to mention the mid-range performance.

Just give yor props a little more cup to the leaing edges It might work better that stepping up to next size. The rev limiter is around 5250 rpms on the 496 HO if I remember right.

Good luck!!!

btw if your removing somthing like stainless marine exhaust manifolds I may be interested in them.

I doubt you will pick up any speed, but they sure do look nice. Get the 525 long tube headers if you have the $$$. The tuned length will help some. I would also recommend dry tails for a few extra HP if noise is not an issue in your area.
