How Fast Should I be going?
 

How fast should my 1994 Cigarette TOP GUN be going with twin Supercharged 600hp engines at 5500rpm? I'm currently at 71 with full fuel and 2 people in the boat. Anyone with a similar setup?

A buddy has a 1994 that Lipship redid in 2004. 500EFI's and bravos. Runs 68 any day and 72 under the right conditions.

Is the Lipship addition carbon fiber?

I hit 71 with Full Tanks....suppose to be 220 gallons.
1 - 1 1/2 foot chop in freshwater.

Anyone else?

Lipship did a complete restoration, but I don't think it was originally a Lipship boat. Not carbon fiber that he's aware of. 68 is in flat fresh water, he claims he's seen 75-76 in 2+ ft "chop" in salt water but without a GPS I find that hard to believe. I had a Formula 382 that was way faster at 3,500 (58) so we rarely ran together except on a few poker runs.

Remember, 220 gallons is heavy, I'm sure his boat is slower when full too.

What size props are you running?

Cafe - 502's with Wieand 177 blowers. I think they put out about 575.

Will run upper 60's in small water but will run about 75 in rough water. You HAVE to be in 3 footers to see speed out of the flat bottoms - honestly there is a tangible difference.

I run bravo 4 blades 26P.

I'm running labbed 26 pitch Maximus. I'm hitting my Rev limiter at 5500rpm. Also, I have them spinning out. I think I am going to add a little more cup, as it does not take very long to get to 5500rpm. I hope to see an increase when I spin them in. If all goes well, I am going to test them spinning in Saturday.

Urban you need 28p 4 blades. My buddy has a 1994 Top Gun with 600SC boat ran 80.6 gps last month when I was on it with 4 people 1/2 tank of fuel in 2' chop. You are definately over revving and will pull more mph when you lower rpm by going up in pitch. Your cruise speed will improve quite a bit as well!

5500 rpm is my max HP according to the dyno. They are roller motors. Does your buddy have labbed Bravo 1 props or Hydromotive? What RPM is running at WOT. This information will be very helpful.

The props are not labbed he is runnig 5100-5200. So for you I would get the 4 blade Bravos 28p and have BBlades lab them per your specs, it will feel like a new boat!!!!!
