    Turbos make all things equal - amazing difference.


    elevation does make a difference but I suggest if u lost that much power you never had anywhere street dragster power to begin with

    I checked on turbocharging my Bounder for just these reasons. A dealer repairman told me all the big block engines only had 2 bolt mains instead of 4 bolt. He said they wouldn't last long under that strain. So if you need more power, you would have to go with a new short block, or trade for diesel.


    I built race car engines for a living this is a fallacy as it depends on the V8 and size of the block webs where the mains bolt on;; rpm expected;; boost pressures used;; compression ratios etc
    rods need pinning etc etc

  • We love our BANKs Turbo charger we carry 30 pounds of boost any where. the old Newmar runs as great at 8k' as anywhere

    yes we were talking non turbo engines my 36 lb boost on my 425ISL works great at 8550 ft
    My banks turbo system on my ISC 350HP cummins worked great at 36-38lb boost
    If your only getting 30 lbs on the banks then its not working correctly because a stock isc will get 28-30 lbs

    I re-set the waist gate to 30 pounds.
    It acts like it is at sea level anywhere.
  • It might be noted that the horse power of normally aspirated gas engines is calculated at aprox 14.14 psi atmospheric pressure and 77 degrees F. Where as turbo charged diesel engines are certified to maintain horse power at 10.18 psi atmospheric pressure (10,000 ft).
