the new powerdyne has gone to a "tapped oil system". If you refuse to tap the pan, then the ATI is a great blower, with the intercooler you loose CFM, so you will need to get more boost to compinsate, say 12 psi instead of 8~10 required by a S-trim. Another problem with the ATI is that you will have to relocate your battery, which i would think is probably a bigger problem then tapping the oil pan (which was easy!) The Novi blower is supposed to be the hottest ticket right now, with alot of potential to upgrade.
