On a daily driver on a 98 degree day... what AIT would be considered too hot? What AIT would be desired realisticly if you could maintain that temp?

 

Do you mean IAT (Intake Air Temp)?? Usually it's best to have it around ambient or lower if you can... The best way to get them the lowest is with meth injection or an air to water intercooler... The only bad thing about the a2w is that you have to have really cold water in there and if you're making it a dd it's going to heat up fairly quick... Just a thought...

 

a good efficient Intercooler will usually keep temps about 10* over ambient. if you can get it to ambient temp or below than your doin well. id say anything more than that and your hurtin yourself.
+1 on the W2A cooler. not a good choice for something thats gonna be daily driven.
