I've got 2x 15lbs under mine, I use the existing tire bracket. If the cops look under there they see a aluminium box... You'll find You'll have issues with your nos going around right hand corners... With a small bottle it's better to have the bottle facing the normal angle with the bottom of the bottle facing the rear of the car.
Also don't do what I did and run dual 0.60 jets. The drive shaft and gearbox can't take it. A single wet fogger is fine on a 0.60 jet for an extra 140hp to the wheels... You won't get any more power out of a single fogger. I'm getting a custom made 4 speed and custom driveshaft for mine to handle the power as I still have my electric powered vortech v3-hb to add to the mix...
