400 SS with Merc 600 -How fast ?

In this article, they procharged a 400ss w/ 502 mags, and it went 66mph.

I'm guessing that the Merc 600's would be in the same ballpark.

Make sure you get an extra drive with it !!!

The Procharged 502 s were rated at 700 PHP (Procharger Horsepower)

With Bravos, the appropriate question is "how far?"

A 400SS with 525's runs up to 59-60 mph on smooth water with the wind and 5 people. With these 600's, the xtra 7-8 mph costs almost 5K per each MPH over the 525's. I am not sure if the leap is worth it??

I guess if you have the cash........

I thought I read somewhere 62 m.p.h.

RedDog, you are correct. we just sold a 06' 400ss with 525s, with an arch, but no hardtop the boat ran 63mph gps first time out. 1 person and 100gal of fuel.

Formula website says "to over 60 m.p.h." with 600's.

based on the number "Juked" mentioned - The 525's seem to be the value then at 63mph- Just don't take a party out with you at speed and the twin 525s will keep within eye sight of the twin 600's until both are out fuel. Sounds like a 5-7mph difference.
