All these performance parts claim to increase HP and such...
When I research these parts on the manuf. web sites, I can never find any numbers to back up their claims...exhaust for instance...
Tell me what the stock pressure drop(Pd) is at a certain flow compared to what the new stuff is. Heads are a different story, I know..they have all the numbers in the world.
What I am saying is that if they claim to add X amount of HP, back it up with some numbers that I can use to compare.
