a borla exhaust was dynoed to add 8 hp to the front wheels.
both mods together were dynoed to only add a total of 20 hp.
adding a ported intake manifold added only 2-3 more on top of that.
it's all about engine flow, as you open more things up certain mods give you deminishing returns, as it's already flowing way better than before.

This guy has it right. At this point, his header probably needed to be upgraded as it was restricting his engine's CFM.
To the poster, the N52 can produce a ton of HP with the right parts; it has the right base for sure, just not enough after-market support yet, which means parts are expensive. If a k
24 (2.4 litre) can push out 295 whp (dynojet) without a turbo, certainly the N52 can do better. Mind you, this guy's build is full racing and probably quite expensive, but it gets the point across. Besides the fact that an 300 WHP NA car will have incredible throttle response and no lagged/surging power delivery, unlike a turbo.
To the guy who told the poster to sell his car and go buy a car with a turbo, shame on you. If you're looking for a ton of power nice and easy from the N52; find/install a small turbo setup (running at 6 or 7 psi) for your machine and call it a day; why buy a whole new car? In general, getting a ton of HP from a turbo is easy and relatively cheap 3-5k, vs NA which can get very expensive but generally nets a faster car (aside from drag racing).
It's up to you how you want to go, but don't ditch the car because it's not giving you want you want, just decide the direction you want to go (turbo/na) and stick with it; both will be rewarding.
