the meth train nowadays is more of a novelty thing, i suspect.
a turbo setup is cool and all, but some of us just want to stick with the m90 and see where it takes us. big power, no doubt go turbo. but if you wanted to run a heads/cam m90 setup to make a good amount of power and just run it as is then that's always a good route as well.
meth will help with dropping pulleys and being able to raise timing. chemical intercoolers have been proven in the right application all over the place. now, it takes the right person to make it work correctly and the tune will constantly need to be tweaked because of environmental reasons, but it does what it's supposed to do when installed and used correctly. you can't drown the cylinders in meth and it's best used as a fine mist to help cover up random detonation spikes. i previously used meth as a 'secondary fuel' and more of an octane booster and it worked for what i was doing, but the car always felt very doggy because i was most likely spraying too much. it's best used in minute amounts to cover up problem areas rather than how i used it.
