Forget the electric superchargers. They do not put out enough volume or boost to do any good. In fact they restrict air flow and can cause a loss of HP in mid to upper RPM ranges.

Ditto cold air intakes. They do produce some gain at wide open throttle, but little difference otherwise.

ECU re-flash seems to be the best bet, but mostly that is a HP vs RPM change.

If it were me, I would replace the air filter with a clean one, be sure I've got 0-40 oil in it and just enjoy the car.

 

That thread is five years old, much of it was in jest.
Read the thread date before answering them.
One of the posters rose from the dead around Easter time, makes you think don't it.

 

no the srt version of this engine has different things in it ,,lower compression,, oil inserts for cooling of the pistons and a lot more. the best thing is to buy a srt6 motor, ecu, tcu, heat exchanger , icu pump,and all the hoses,brackets and all the other things needed with making the new ecu(computer) work wiit the new engine will cost lots.
or you could buy my graphite srt6 , or i could install a V8 in it then sell it to you. or i could install a V8 in your car. jim
