I believe the Paxton Novi 2000 is a Draw Thru System but when adding the air to air cooler this changes to a Blow Thru system...this is something I need to know so I can select the MAF for my friends setup..
You can still have it draw thru with an air to air. The MAF will still be before the blower. If you want you can make it a blow thru tho. I'm making my set up a blow thru. I'm using a blow thru MAF and placing it between the TB n intercooler.
