tune for meth and have a leakdown, run out because your failsafes didnt work and you could pop a 36,000 $ engine. this is a non forgiving way to advance timing and it only takes 1 issue to give you a huge paperweight
Yes and mostly no. Factory intakes on most cars suck in warmer air and also heatsoak so whenever the car warms up, you never have the horsepower that you potentially could. Cold air intakes do provide gains due to better flow but mostly due to much lower AITs which would not be there with a factory intake in the first place so yes you gain horsepower because the horsepower that the car is rated at takes into consideration the factory 'hot air intake'. You can also have a huge paperweight due to increased boost so why do we bother adding pullies? It's always about horsepower gain versus longevity and stress on the engine. Methanol systems are extremely reliable and have been around for so long, if it's done correctly there will be no issues. Look at Mitsubishi Evos, so many of those guys run meth with great results and no issues whatsoever. A conservative tune on meth will actually be easier on the engine, fuel burn is greatly improved without having have to resort to race gas. Why knock on something that so many people run in their cars with absolutely no problems.. in much more expensive cars than SRT or SLK for that matter.
