Default generator operated blower

Just thinking, because I am kind of wired that way, but if I have a diesel with severe intake restriction and no turbo, how about running a big squirrel cage blower off the generator and force feeding the air when a litle extra power is needed for a long pull? 636 cubic inches times 2600 rpm equals 1653600 cubic inches per minute, or 957 cfm. You could run a 1200 cfm blower with a 5 hp electric motor running off the generator.
Just pondering.

or just hook up a two - stroke powered yard blower and attach to the intake. I've that done to an 80s corvette in hot rod magazine. It gained 100HP.

What you are proposing is quite inefficient, but entirely possible if properly engineered.

How would you plumb it into the CAT and where would you locate the blower and the motor? I just added an extra 4 inch air intake to my CAT 3208NA and it made a difference and I'm always pulling my enclosed trailer too.



Even with the CAT 3208T 225 and 250 horsepower engines it can sometimes still be slow going in the long hills, the 300 horsepower models are better. Learning how to drive one using the sweet spot helps considerably too. Wanderlodge Owners Group > Mechanic's Corner > FC (Forward Control Unique Issues) > Throttle Sweet Spot

Hey, I am just the idea man. Its up to you smart guys to put my plan into high gear and actually make it work.....
But on sort of the same subject I was thinking (just thinking remember. I have no plan to attempt any of this) that you could stuff a marine 3208 in there and put a massive rad laying down on the roof. Then the air to air could go where the rad should be since that has to be close to the turbo.
