anyone know where i can find a simple place that tells you approx how much power each power adder is supposed to give you.such asEldelbrock heads give you x amount of HP and so on.
im trying to google some of the parts i have to see what they are claimed to make but theres so much bull**** and nothing with what im looking foR!!

 

It'd be tough to find a site that gave "honest" horsepower gain charts, maybe one of the online car magazines that dyno tests stuff? Yea the product manufacturers do tend to overestimate power gains.. I'm really doubtful just adding a K&N filter into my car is gonna give me 25 extra HP

Another problem though is if you're adding a couple of bolt ons the combined increase is tough to estimate. Adding just an intake will give you XXX more horsepower, adding a cam would give you YYY more horsepower. Adding both won't necessarily give you XXX + YYY
