Thinking about adding meth

Hello...If I add meth (looking at BMS System) under CPO (43K right now), what will be involved in removing if I need servicing? Is it intricate or pretty straight forward? Hoping Calwaterboy might give me his insight as well. I already have a JB4 I installed myself so was also planning on doing this myself as well.

Thanks

I don't recommend installing meth w/charge pipe, tubing, etc., if you're anticipating removing it for dealer service. First, touch shady. Second, PITA!

I do recommend it for that youthful, s**t eatin' grin and confidence of knowing that kick a**, leave-'em-dumbfounded performance is a couple o'button pushes away.

Risks. Your ride has sintered connecting rods - the out of spec, add'l stress at the apex of a down stroke can throw a rod! Think: Beyond Economical Repair. Yup, just ask SneekyDeeky. Also if manual trans, all too easy to over-rev. Can be major. In general you're operating beyond the design envelope of the engine from time to time, but on the upside, you're burnin' twice as bright!

Hey, according to Ian Fleming, Mr. Bond was warned in sobering tones that supercharging his Bentley carried great risk they would not be responsible for. The name was Bond....James Bond.

Just to add, meth itself is dangerous & needs to be respected. Even a 50/50 mix can burn. Always use first level components & fittings. DO NOT try to cheap out & use the window washer bottle as your meth reservoir. All the cheap kits do this but you should buy a trunk mounted meth specific tank & pump. In other words treat it like you would any fuel (gasoline) & you will be good to go with an abundance of additional power.

I'd do the flex fuel wires instead if you haven't already. Everything I've read says that with E85 there is no need for meth. Only concern would be the corrosive nature of E85, but it would still be much easier.

I think about doing meth all the time, then I watch one of those meth baby videos on youtube and have a change of heart. Like they say once you go meth... meth
