Whipple???

[rktman]

last summer I bought a 2004 18 classic with a 350 mag. It runs about 67mph. I would like to run around 75mph. I was thinking about installing a whipple supercharger.....am I nuts? The engine has about 90hrs on it. Alpha drive:confused:

[zelatore]

nuts? No. 90 hrs shouldn't be a problem assuming the engine's in good shape. As for the Alpha, it's life expectancy will be directly related to how you drive the boat - you'll have enough power to grenade it if you're ham handed, but I would expect it to survive if you're gentle. At least long enough for you build up the kitty for a bravo switch in a season or two.

Of course, the bravo will cost you a mph or two as it's a physically larger case.

How much would a whippel cost.How much hp does that give to a stock 350.

There's more than one 18 around here that's capable of 80 ish that are small block powered......lots of them are 383's and NA.
I think the 18 responds very well to a few more cubic inches.

Thats what i was wondering what is better.I just did a 383 with 400+hp running inthe high 70.with a alpha drive which is working great with a 25p m.I don't know which way is cheaper.:boggled:

[rktman]

It looks like the complete kit sells for about 7 grand...not cheap but by the time you have a new engine built with a fuel system its gotta be close. They claim all you have to do is send out the ecm and they map it for the blower.

[craigdskilling]

Well thats pretty close to changing your motor to a383.If you change just think you will have a brand new strong motor to play with.:popcorn:.craig

I know where a balanced/blue printed 383 400HP is with a one year guarantee for $3,700, "PM" me if interested it won't last long long now that the cat is out of the bag!

It's worth talking to Mercruiser. they have a trade in program, and a couple different 383 engines you may like.

whipples are nice but annoying after a whyle,,do you have a 555 ecm??????

non programable..

sell your engine as a complete package and buy this http://www.youtube.com/watch?v=bbCVXPoIeCA&feature=related

they say bravo application but u can make it work with a alpha..

[rktman]

yes I have the 555 ecm....I guess they will work up till' '08 with the whipple. They are actually liscenced at whipple to work on them. That 383/400hp Merk is impressive.

Wow, he says that motor idles at 700 horsepower. :bonk: Crazy that they let that slip through.

Whipple.. :wink: :cool:

Whipple is a great way to go if you want to add boost. Bad idea tho wanting to put it on a boat with an alpha drive.. That is a lot to throw at that drive. A bravo would be better candidate to up the power on.

While I am a big cheereader for superchargers, you may be better off repowering & converting to a bravo at the same time. At least if you plan on 2 things.. Keeping the boat & Using it frequently.
