What are the main differences between these 2 blowers,I have read where the Magnum Power Blower is almost identical to our stock Eaton with a different casing making it flow to a 120 producing a estimated 70HP and the ported Eaton is just what it says it ported producing nearly 35HP with our stock Eaton. Dyno numbers are nice but real world track results is what i will be looking for! Both of these blowers look to be very promising for a affordable price and just trying to get as much info as possible on these 2 blowers.
