why before the turbo inlet??
im going to tap and install both on my intake manifold. a straight shot to the heads
alright got my trunk meth kit. here are my duals...

no they cant. drill and tap under the manifold and run the lines underneath that ****. pretty easy. use your windshield washer take as the reservoir. i ran mine like that, hid the pump too.i will find the link...

The stock Continentals aren't as terrible as many make them out to be. Too many people expect more than can realistically be provided by a three season tire. While they ContiSportContact2 doesn't offer class leading grip in the dry, they do very well in the rain, provide reasonable tread life, are a very predictable tire at the limits. There's a reason they are an OEM tire on cars like M3, AMG models, and other high-end imports.
Also for the LNF owners in the thread, remember why you'd want to add meth/alky to the car. The primary uses are for extra fueling and for preventing knock. It your car isn't running lean and you aren't getting knock then there will be minimal, if any, power gains (inject too much and you could hurt power). You'd want to watch the factory wideband and see if the engine is knocking and pulling ignition timing before just dumping fuel.
It would also be good to monitor intake charge temps going into the engine. The water or alcohol can be used to an extent for evaporative cooling. This can cool the charge which helps with detonation/knock control and increase the density entering the engine, but the water vapor is also taking the place of fuel and air that can be burnt. If the intercooler is working affectively you shouldn't have excessive charge temps.
If your charge temps aren't high, you aren't lean, and you aren't getting knock you don't need alky injection. If you'd like to install a kit anyways you'll need to tune specifically for the blend you want to use. For example, if you're going to use a water/methanol mix the methanol will raise the effective octane of the air/fuel charge (since it is a fuel that happens to have a higher knock threshold) and allow you to run more ignition timing and also lean the car out.
The risk is that if you push it to the ragged edge and have a pump or line failure, run out of fluid, or something like a nozzle gets clogged while under heavy load it could have catastrophic consequences depending on how aggressive you were on the tune (and to make significantly more power you'd have to push it pretty far).
For those with experience and coming from the LSJ it is very effective on those cars because of the massive amount of heat that occurs when you over spin the M62 and the stock fueling system reaching limitations. These are not the case with the K04 turbo and direct injection system on the LNF. I always say to make sure it will work with your car and is what you need before slapping parts on.

Just making sure everyone knows what it can and can't do. In some other threads I've seen people wanting to install it on cars without changing the engine calibration/tune thinking it will provide magical benefits. Then if you tune for it and push the car to get the most power there are also risks.
The power from methanol comes from increasing the density of the charge and allowing more ignition timing. You wouldn't want to pull timing. That's assuming you're knock limited and haven't already reached MBT (minimum timing for best torque). Peak power is always made at MBT and it is possible that in certain engines under certain parts of the power band that knock isn't an issue and if you ran more timing you'd get a drop in power. More timing is not always better for power.

Cole, the reason you want to add meth at the turbo intake is because it will lower the the charge temp at the source...cooler ait's = power....and then your second nozzle at the TB functions the same way as the lsj.
