ZT 260 GPS speeds with 496Mag ho

[Liquid Missle]

Hi, I am looking at a 2003 ZT260 and am interested in what are the confirmed GPS speeds that this boat is producing with the 496mag HO in her.....stock. I am also what she is doing with a mild Procharger set up. http://www.checkmate-boats.com/6/ws/,s,8626072361/Graemlins/thumb.gif
Thank you for your responses.

There was a rwrite up in Procharger's brochure on a 25 foot check with a 454 mag (365) horse. The boat ran 58 on gps without the charger and with a stage 3 procharger set up with 5lb boost ran 74 on gps. So in your condition, a 496 HO Mag (425) horse stock which is suppose to run alittle faster, Maybe 65 mph. then you should see around 75 or 76 with the procharger set up that is specially designed for the 496. Call procharger they will tell you what to expect. Bill why don't you add your $.02 to this question.

I own a ZT 260 with the 425 Mag HO motor... GPS indicates 67.5 as I recall. Speedo shows 74mph

Overboard: is your supercharger a "Pro-charger"? How long ago did you install it and how has the reliability been? Interested to know. Thanks.
