    Default New Daycruiser purchase

    Hello,
    I am fairly new to boating and purchased a 1985 22 Nordic Daycruiser. I wanted something to handle the parker chop, my friend already has a pretty insane alcohol flat for go fast fun. However, I gps'd it on Mojave and it ran 55.6 mph. I am not expecting much more out of it with the pretty stock 454 BBC and dominator w/ a droop. I would like to get the most out of it without throwing good money after bad. I am planning on freshening up the jet and adding a place diverter before the start of the season and a friend of mine might have some thru transom headers at a good price, is there anything else you recommend to make it the best it could be while still staying true to the cruiser purpose it has. 65 mph is my lofty goal.
    Regards,
    Tom

    You'd need another 120-150hp.

    A small blower (B&M or Whipple) will do the trick with modest boost (stock short block).

    Almost three decades ago - a guy came to me with a Tahiti 21' open-bow. Berk jet with a stock 454. He was getting beat by his buddies and wanted another 10mph or so. We never touched the jet and added a 177 blower with an 850DP on top. Upgraded the valvesprings and added roller rockers for durability - as well as the added RPM it would be swinging.

    He gained 14 mph at 6psi of boost, for a very modest amount of $.

    Tom The pump is a good place to start and a Place Diverter is a must. These two mods should get you close to 60mph. If you go with exhaust I would not advise water injected headers and go with a completely water cooled exhaust system. I your engine is running log manifolds at this time you will be pleasntly surprised by the gains you will receive with a good exhaust system.
    A small blower could be an option. What engine do you have? 454 330 hp version or a 454 mag. I would not put a small blower on the 330hp version. This engine has cast pistons, cast crankshaft, small pinch port cylinder heads, plastic cam gear , small rods just not a blower friendly engine. If you have the 454 mag a blower could be in your future .Forged pistons, steel crankshaft, large retangular port heads, 7/16 rods good timing chain and gears ,just an engine that is more receptive to a small blower. However if you do have the 330 hp version intake manifold, good inginition, cam and lifters,upgrade the push rods to 3/8 ,a set of roller rockers, with a good tune up and you will get a whole lot closer to you 65 mph goal!

    Thank you for the reply Greg. I will have to investigate my motor further, I know the previous owner had whatever it started life as rebuilt about 5 years ago out in Vegas, unfortunately he did not have any of the corresponding paperwork. The last thing I will touch will probably be the motor as it is very nice to have something you just tap the key and starts right up every time. I have a chevelle that I have been racing for 14 years with a pretty radical big small block in it and I don't wanna start something else like that. The water jacketed thru transom headers are what I have a line on right now, seeing if I can get them from a friend to replace the logs and snails I have right now, hoping that will give me a bit of performance and the place diverter I am really excited about not for the speed pickup, but the general manners of it at cruising speeds. Looking forward to keeping the nose down at 35 and keeping it on plane easier. Thank you again for the feedback.
