Proven gains: aem v2 intake, DC header, grams exhaust

Here's a old link from 2004 from the superstreet magazine. They show a ap1 on the dyno and did before and after pulls with no tuning. Now,from 90% of the things I read on here, everyone says the DC header loses power. Its a proven gain all across the power band. The intake is the v2, which have been proven to gain power on this link AND mighty car mods. The exhaust is probably a old rare piece since I've never seen one for sale on here or hear about anyone having it.

But overall, I kinda get tired of everyone saying "the DC header loses power" and my favorite, "mods on the s2000 actually lose power". Theres no proof that any of these are true. Only seen proof that there's only to gain with these. Opinions welcome

In most cases, I don't ever recall people saying most mods lose power. Maybe once or twice.
I think it's that most mods don't give you much gain for the dollar.

Lets make up numbers here:
On another car, spending $300 on an intake might get you 8hp. $38/hp
On the S it gets you 1-2. $150/hp at best.

Not a very efficient way to spend money.

Yea true. The cost to power isn't so good. But I've read countless threads of DC losing or not gaining power. If I see a DC header for dirt cheap, ill scoop it up.

I think the problem is, 10 years ago that statement was true, and a lot of people just keep saying it rather blindly. There wasn't enough R&D going on in the aftermarket performance industry to really be producing bolt-on parts that increased the S2000's power. The S hasn't even been made in the last 8 years though, and companies have had a lot more time now to perfect designs and structures to where just a header, test pipe, and intake on an S2000 can get you at least a 20WHP gain and a lot more response in the midrange.

The only way to make SIGNIFICANTLY more power on an F2*C engine would be to go forced induction, but that in itself is costly and can be a huge investment in time and headaches if not executed perfectly. Going with a reputable supercharger kit would probably be the best bet, but you start running into other weak links in the car after that as well.

Every route has pros and cons. It's really just up to the owner/builder where their priorities are. N/A mods for the S2000, if you just want a bit more kick in the throttle while still having OEM reliability is entirely worth it IMO.

I was specifically referring to OP's reference to mods losing power. Nothing else.
