This is the last mod you should do to a turbo car.
How ridiculous is it that a 300whp car can only run with alky while there are plenty 900WHP+ cars running on pump gas all day long.
This is not only far from the only way to safely make more power it is one of the worst ways to do it imo... You have a giant band aid on your car & if it ever failed your motor is toast.
Plain & simple.

Meth is great for boosted cars when it is used correctly. It is a safety net, especially if you are trying to run pump gas. The proper way to do it is to tune the car on whatever fuel it will be running with the proper timing+boost and everything to prevent detonation without using Meth. You act as if it isn't there. Then, after that tune is completed, you spray a small amount with either a progressive box or just a WOT switch. Since your tune is not taking that meth into account, it richens the mixture, cools the IAT (Intake air temperature), and increases the effective octane of the fuel. Since you are spraying meth "on top" of the tune so to speak it makes running pump gas much safer. If you get a bad tank of gas that is say, 89 oct instead of 93, you won't have any detonation and your motor will stay together. Conversely if you are spraying "on top" of the tune and the meth fails to inject, the car doesn't NEED it to keep from detonating. That happens more often that most people think. Those pumps aren't the most reliable and all it takes is a clogged nozzle.
Now, if you do it like Eric is doing it you are asking for trouble. People do it all the time but it is the wrong way to do it. You shouldn't spray retarded amounts of meth and tune for it. That makes the car dependent on it. If for some reason it stops spraying you are completely and utterly boned. The motor is going to grenade itself in the matter of 100-200 revolutions. That is when it is being used for a bandaid to cover up an inefficient combo.
Call any shop that builds REAL high dollar street cars that are running Meth injection and ask them how they use it and how they tune for it. They will tell you off the bat that doing what he is doing is extremely risky and usually scrubs desperate/poor people are the only ones that do it.
It seems like the first mod. Seriously, call EFI Logics and ask them how to run an sti with meth/water and if it should be one of the first modifications done on an upgraded turbo, injectors, etc. It helps cools the car dramatically. I don't understand what you people don't understand about this.
