What is the easiest and cheapest way to get 400 horsepower out of a 5.9 liter dodge motor?

Answer 1

Nitrous Oxide N2O or commonly called (Nitrous) is the cheapest and easiest way. But it is also the easiest way to destroy your engine, which will not be cheap to repair. One of the major problems of using nitrous oxide in a reciprocating engine is that it can produce enough power to damage or destroy the engine. Very large power increases are possible, and if the mechanical structure of the engine is not properly reinforced, the engine may be severely damaged or destroyed during this kind of operation. It is very important with nitrous oxide augmentation of internal combustion engines to maintain proper operating temperatures and fuel levels to prevent "preignition", or "detonation" (sometimes referred to as "knocking" or "pinging"). Most problems that are associated with nitrous do not come from mechanical failure due to the power increases. Since nitrous allows a much denser charge into the cylinder it dramatically increases cylinder pressures. The increased pressure results in heat, and heat will cause many problems from melting the piston, cylinder head or valves, to predetonation. Read up on Nitrous and how it works and what power gain can be achieved before attempting to use it. There is really no other cheap way to gain lots of H.P.
