Okay, i just installed my cone filter after the air flow meter, but there was a hose that hooked on to the air box, and went to the air pump, the hose is now loose, what do i do with it? thanks.

Whatever you want, lol. Thats just the feed for the air pump. You can buy a little breather for it at Discount Auto Parts(if they have those where you live) for like $5-10. Do you still have your cats?

nope, well i have them, but i gutted them

Well you can get rid of the airpump altogether then. Just do a search. Basically you'll need a dual alternator pulley to prevent the water pump from cavitating.

oh, i see, well, let me ask you another question, what is the little tube that comes out of the stock cats (gutted) and goes somewhere in the motor, im not sure what it is or how it works, but that's one of the reasons why i gutted my cat instead of just straightpiping it

It goes to the air pump. It feeds fresh air in so you burn up your cat. Thats why you can now remove the air pump, because you don't have a cat.

thanks bro, tommorrow im putting in the little breather until i stop being so lazy and actually take out the air pump. BTW any other tips on making a quicker na, got tires bigger tires, got intake, got exhaust, checked my sixports and they're ok. What else can I do.

There aren't too many inexpensive options to make NAs faster. You can free up horsepower by removing p/s, a/c and getting an electric fan. Also removing weight will help some. If you want to be alot faster you'll need forced induction, I suggest a small shot of N2O.

what would be the best nitrous to get me up in the 200's? what company would it be from, and is it safe?

The dual-belt alternator pulley is required to stop the alternator/waterpump belt from slipping, because the water pump used to drive by the air pump belt as well. It has nothing to do with cavitation; that's caused by spinning the water pump too fast for too long (i.e. contant high rpm). Just clearing that up.
