Re: o-480 rpm question

I believe the 480's will turn more RPM than 3000 but what prop are you wanting to run ? most all the direct drive props say no more than 3000. Yes you can turn the s/c motors harder and get more HP because of added boost pressure at higher RMP's but even at 3600 engine RPM with the gear box you are ...

Gauge package suggestions

After a long drawn out process I'm about to start my part of my new boat build. I know the basic gauges will be in the gauge package( tach, oil pressure and temp plus voltmeter ) just curious as to what others thought should be included to keep up with all functions of the engine.

Diggin if you call the Autometer tech line they will most likely be able to give you the info you need. More than likely it is a sensor mismatch that is causing the problem

Keebo from what I understand Norman can do just about anything you want. I had a set built with cones up in the collectors and slightly longer collectors with O2 sensor bungs welded in each side. Not sure what you are wanting done but bet he can do it and his work is top notch
