Top speed of a Sunsation
 

Hi,

Anyone know what top speed I can expect from a 2000Sunsation with stock 454 MPI's, 28P props? The owner claims 75MPH.

Should be just about there.

No more that 74.4

/Sorry couldn't resist

MAG's? If so that is pretty accurate.

Thanks. The reason I asked was because I was on a friend's 1999 32 with 454 mags but the speedo only bounced on 70 a few times at 5000 rpms. Could it be because he has his speedo hooked up to one of the plastic pick up tubes instead of through the outdrive? We did not have GPS and it seemed like his boat should have done better.
Will all the 454 mag Dominators do 75-78?

Only check speed's with a GPS. Even a handheld unit works good.

There is a droid GPS speedometer app.
I have it on my droid now, seems to work ok.

Are you looking at the one for sale near Windsor? If so, that is my brother in laws boat, 75 is about right, I had a '96 with 502mpi's & the best I ever seen was 78

I had a buddy with a 2000 Dominator with twin 454 MAG's turning 28" labbed props at LOTO. Boat was a 75 - 76 MPH GPS boat every day. I believe one morning he had the perfect combo of chop, air temp, humidity, fuel load, etc. and just tickled 80 MPH.

He is not talking about mags... read his posts closer, his buddy has mags and he wants to know how similar the 454 mpi's are. The boat should run about 70 with 454 mpi's.

75 sounds about right. The smallblock 32's run right around 71-72.

I thought all the fuel injected 454's were mags.

You are correct. A Mag 385 boat will go 75. MPI 310 boat will be lucky to hit 70.

No, where is it advertised, I am looking to buy a 32.

Check speedwake.com classifieds

non mag efi is only 310hp

I thought they 310 hp engine was a carburated 454.

The carbed 7.4's were rated 330hp the carbed MAGS were rated 365hp. When they went to fuel injection the 7.4 was rated 310hp and the MAGS 385hp.
