Dude! Seriously, do you know what you're saying?!! Okay, if you're so sure the intake will give you a 10-12 WHP gain, please go and have your car dynoed before and after. And you're talking about WHP gains. I guarantee you will not even see half of that!! You'll probably only see those type of gains with a header and cat-back exhaust. What in the world are you talking about?!Ormand wrote:That's pretty much BS. The gain from an intake will depend on two things- one, how good was the intake you replaced, and two, how much power is the engine making.The stock intake on the Altim is pretty restrictive, and the 3.5 makes substantial power, so the 10 or 12 hp gain that is shown by most dyno tests seems to be reasonable. Bigger gains than that have been shown on cars making more power, like Corvettes. And the gains show up on the track, too, so they are NOT just bench racing claims. Exhaust gains may not be as much, since you can't do anything about the cats. On the other hand, of you could replace the ENTIRE exhaust, including the headers and cats, a gain of 30 hp would not be out of reach.
And 30HP through the exhaust?!! Please go and do those mods so you'll have the first 300HP on here.
I did notice a slight increase in throttle response, but definitely not 12WHP worth
