How much HP are you looking to add ? I don't think you'll find an 02 sensor on a stock motor. I think you would be best off using a plate under each throttle body and a stand alone fuel system for the n02.

GPM, I ran 100hp nozzles on the old boat but would like to jump up to 150 for the new engines; plan to use a wet system with fogger nozzles...

You can get fuel from either end of the rail. The end by the dist has a threaded plug and the front end has a schrader valve to release pressure manually.

hey i was just wondering thoughts on nitrous on my application. I have a fresh rebuilt 454 full roller engine was a 454 mag. I just wondered how anyone has done it in the past and how much it helped.

I had nos on my 89 challenger v24. At the time I had nos on it the engine was pretty much a stock 454/365 Mag with a 420 camshaft in it. I used nos for a couple of seasons and it was a grin. Those boats had a pretty slippery hull so the gains were pretty good at an instant 7 to 8 MPH. It was fun however I would never do it again. I drink way to much to use it without the concern of blowing an engine.
