    Does methanol effect AFR?

    Adding a meth system to my car to lower intake temps. Hot summer and I customized my air filter system to be less restrictive but its getting hot air off the engine now and intake temps have risen a lot. Not getting knock retard or anything but I would like to keep the engine safe.

    99 Camaro SS.. there isn't a whole lot of options when you go above 4" on the intake. 102mm is 4.375 inches and the stock Camaro SS intake system is restrictive. Surface area and feeding a big cubic inch engine is the issue.

    I've found a filter with an orifice that is 4.375 but I have to clamp it direct to the TB. SO I get heat off the engine now.
