Default EVO 28 - Merc 496 HO w/ CMI and Procharger?

HI!

We seriously consider to buy a new Laveycraft EVO 28. Unfortunately the Merc 525 EFI is not approved by EU, and the budget does not allow us to buy the Merc 600 Sci.

A reasonable solution is to buy the Merc 496 HO and add CMI Sport Tubes. This will add approx. 50 hp to a total 474 HP. When the warranty is over (2 years), a Procharger / Whipple charger can be bought to increase the HP further.

My doing so we save approx. USD 35.000 due to certain tax rules in Norway.

Is it possible to combine the CMI Sport Tubes and the Procharger / Whipple chargers? What kind of gain can be expected with this combination?

We will buy the Bravo XR drive from the start, to allow the upgrades later.

Laveycraft states expected speed with a Merc 496 HO to be 78 mph. Seems a little high? How fast should another 50 hp and CMI Sport Tubes give us?

Cheeeers! Toffen G

A buddy purchased a 28ft Conquest deck boat last fall, with a 496ho and CMI headers.The boat ran 70. He promptly installed a Whipple Charger with intercooler, and larger heat exchanger, and gained a solid 12MPH.

Toffen, I have a Lavey 29 Nuera for sale with a Keith Eickert blown 540 motor 850hp and IMCO Extreme drive with full hydraulic dual ram. 40hrs on it. All top of the line parts used throughout and boat was custom rigged as a show boat for dealer. Triple Axel trailer and to many options to list. New would be 175K and I am selling for 115K if interested...

Default Evo 28

Hi!

Thanks. I have been in contact with KCooper and are awaiting some info.

According to Nortech agent in Norway it is possible to import Merc 525 EFI if I have a Bravo driver due to noise regulations. So I will double check to be sure.

The reason we are so exited about the EVO 28 is the cockpit. And she is a Outerlimits fan...

Cheeers, Toffen G
