[QUOTE="phantom240, post: 1579645, member: 562504"] Okay, heres my 2 cents on the proposed mod. The scuba tank has a higher oxygen content than normal atmostphere right? Well if it does, than it will work along the same lines as NOS, which is used to increase the oxygen in the combustion cycle through the combustion of its cehmical compund. It then, theoretically, SHOULD add more hp, but i will guarantee that unless you set it up to inject in the RIGHT SPOT, your motor wont make full use of it, if at all. My car, for instance, has a mass airflow sensor (MAFS) that sends a signal to the ECU to increase/decrease the fuel mixture in conjunction with the O2 sensor.
