I was wondering what's the cheapest product out there that will add the most horse power?

 

N02!! nitrous is the best bang for your buck HP increase...

 

nitrous. hands down but in the end will add up to costly dollars filling the bottle.

 

lol, I don't have the 500 bucks to put into it though, I was thinking more along the lines of a CAI or Xpipes, stuff that isn't TOO much money.

 

Underdrive pulleys, and CAI...

 

K&n air filter....one of the first changes you should make....can add up to 10 hp and only cost you about $40-$50

a CAI isnt needed yet. stock airbox can stand up to 340hp or so. pulleys, headers, offroad pipe, cat back. youll be happy for now

 

yea but something like a bbk cai is better it auctly helps it breath better, ide say cai and exhaust

 

That is very inaccurate... A K&N in the box will yeild the same performance as a CAI... I have heard of many people accutally getting better performance out of the stock box... I would rather save the money and go with the K&N... I will try and find the article which actually states that the made better power on the dyno with the stock box... I will def. have to find it for you guys.. The HP rating is not going to determine how much air the engine needs.. The only thing that is going to determine the need for more air is the parts that you have such as heads, cam, intake..

 

i can think of a couple free mods: get rid of your smog pump and all the lines, and remove the air silencer. don't get a cai. put a K&N filter into the stock airbox. if you remove the box you can see that you can cut more of the fenderwell out to get more air into the airbox. another way to get more power is to bump up the timing to 14* and than run 91-93 octane.
