I am planning to SS normalize my Renesis. I am looking at two Eaton
units. The M45 and the M62. The M45 is advertised for 2-3L engines and
the M62 is advertised for 2.5-4L engines. Will the smaller / lighter M45
be sufficient for this application. Altitude normalization to 8000ft
will require 3.78 psi of boost+ inter cooler loss etc. I am planning for
4.75#'s at 6800 rpms.

Thanks,

Bobby Hughes

I think you will need the bigger unit. The high power RX8 engine is
the equivalent as far as pumping air and HP at 6800 RPM are
concerned to about a 3 L engine. My guess. About 200 HP climb power.
Stoichiometric ratio = 14.9. At a .55 BSFC = 110 pounds of fuel per hour or
18 gallons per hour. That means you will need about 1600 pounds of air per
hour or 27 pounds per minute or .45 pounds per second.

BTW here is a picture of a Limo EZ with an 13B and an Eaton blower. It is
very strong to say the least :)
