Power Gains for the HPF carbon fiber air intake are in (11.5rwhp gain!)

[HPF Chris]

We've finalized our testing on the carbon fiber intake air pipe for HPF turbo stages 1 and 2 and the results are in.... As you would expect the gains are greater when the turbo kits intake pipe and filter start to become more restrictive.

Dyno Tested Peak Power Gains for Stg 1:

Pump Gas = 3 rwhp gain
Race Gas = 11.5 rwhp gain


Dyno Tested Peak Power Gains for Stg 2:

Pump Gas = 3 rwhp gain
Pump Gas and Alcohol = 5 rwhp gain
Race Gas = 11.5 rwhp gain
Race Gas and Alcohol = 9.5 rwhp gain


Here are the specifics....

"The HorsepowerFreaks 4 inch carbon fiber intake system allows more air into the engine with less restriction. The carbon fiber intake pipe is constructed from 2x2 Twill Carbon Fiber and the air filter inlet is increased from a 3" diameter to a 4.5" diameter. This intake pipe and filter alone result in power gains over the standard 3" intake on HPF stage 1, 2 and 2.5 turbo systems with no ECU programming required.

This intake pipe has been designed to be as efficient as possible with the constrained engine compartment. It has been molded to route perfectly through the small opening on the passenger side of the engine bay while maintaining it's 4" diameter all the way through to maximize air flow. Even though this is a beautiful piece, it wasn't designed with that in mind. The 1 Inch increase from the 3 Inch Air Intake is simple, yet extremely effective. If you're looking for a cost effective upgrade for your Stage 1 through Stage 2.5 Turbo Kit, check out the Horsepower Freaks 4 Inch Carbon Fiber Air Intake. "

ordered mine today along with the cf engine cover :bow:
now you guys need to get that filter cover induction piece fininshed!

Basically, reseller of K&N? Slap on a carbon fiber tube and rebrand it to HPF?

Are you an idiot? It's specific to their turbo kits.

Not quite, as you can see its not just a straight tube. :loco: This took more R&D then you would think.


Beautiful piece, its a shame you will not be able to see it when installed. :)

what a fruit loop :loco:

i guess you think they just took an ebay turbo kit and slapped an HPF logo on it too right? :facepalm:

[Evil Twin Rob]

I've seen this piece installed, and it's more than just a carbon fiber tube. The indentations up by the filter are to keep maximum airflow while being routed around all the crap between the filter and the turbo.

Chris!!!! What were my final numbers?:bow:

i love mine and it also looks really good :thumbsup:

Obviously a fluid dynamics engineer, right?

EDIT: Guess I was beaten to it.

Excuse me people. As with any innovation (in this case, nothing more of the carbon fiber tubing and design), there will always be people to review and critique. That's the reason we have forum to discuss. No offense to HPF but someone please prove to me that my statement is not true. I never said it was a bad intake in any way. Regardless, (to further reiterate my point) my concern was the difference between this intake and the hundreds that are out in the market. And I know it's made specifically for HPF turbos (as stated and branded with "HPF") so you don't have to remind me either (I wonder what K&N have to say about the direct competition now -- maybe it's with exclusivity rights).

BMW spent lots of $$$ in R&D designing the stock intake/box specifically for BMWs. Yet, we as consumers still critique about it. So why are so many people butt hurt about my opinion? Peace out!

I think the point was that it does utilize the k&n filter, but the tube itself has been redesigned. So now there is power gain over the intake the HPF kit utilized. I bet the old intake used k&n filter as well, but maybe different shape/size because of the different tube design, which was kinda "bottle neck".

Penn, I agree and the utilization concept is fully understood. Still, I think it's unfair business practice to tweak and rebrand a competitor's product in direct competition with them. That was my point in my bottom-line critique of the product regardless of the performance aspect.

[Penn]

What your saying is, that when Hamann (or who ever) tweaks BMW engines, they do not server the right to brand them as Hamann? ...just because it uses BMW engine as base?

k&n and HPF aren't competitors.As far as i know k&n doesn't sell kits for HPF systems. So that's the first aspect where you go wrong.
Nothing bad at criticism, but i don't see how HPF branded the product wrong. HPF built the turbo system from various details/parts. It's not like they will name the product after filter, BOV or turbo it utilizes.
Also I'm sure the clamps the intake kit uses aren't made by HPF as well, that doesn't make it less HPF intake kit for their turbo system.

Ok, then who makes this exact intake? This was designed by HPF to squeeze past the turbo exhaust manifold and their motor mount. How can this be rebranded when they are the ONLY ones with those two pieces?

[InDiGlOM3]

Gen247: In no way does this intake have anything to do with the K&N intake system for the M3. The K&N system is built to connect to the factory airbox on the driver side, where the intake and everything is on the driver side of the car. This HPF product routes from the top passenger side down to the turbo.... and then uses a K&N filter. Does this make since to you?

what a dick....:blah:

[AMG ETR]

Wow, that guy might be one of the dumbest people alive... K&N sells generic filters so that individuals and companies can make their own intake systems... Not only do they care, they encourage it... K&N cannot make an intake for every application, they welcome companies to do what they can't!
Wow...

[SeanC]

A filter != a cold air intake. What was that guy thinking?

[funkboy316]

guys....we've been had. both AA and VFE use filters by another manufacturer. How dare they sell REBRANDED S/C kits......lol:rofl:

That's exactly what I was thinking but I don't have an hpf kit an wasn't quite sure. This intake obviously has nothing to do with the k & n (for a stock m3). There's a difference between critiquing something on a public forum and just running your mouth

[Greg Ogden]

If anyone wants a K&N Intake you can buy my old one....;)

[gasser]

ordered mine today. don't know if my butt dyno will be able to tell the difference. but, at 22psi it has to help out more than at 13psi. :woot:

Gen247 you're one of the dumbest people to post on e46.

This tube is made to enhance the intake to the turbo, not to the manifold.

This is only made for HPF turbo kit, nothing else.

I'm thinking, you were thinking this is a normal CAI for NA motors like any other out there; but its used for another reason.

What's the whp gain for stage 2.5? :)

[2000_328CI]

They haven't had one to dyno yet. :shhh: But, mine is ordered and we will see. :yikes:

[hawkgoalie31]

Why use such a small filter? looks like it could be designed slightly better...

K&N has no exclusivity rights to the e46 m3 CAI market. But I do think that is a K&N filter. Despite the visual appearance and similarities to K&N, it is not comparable. This is exclusively for the HPF turbo, not just suggested use.

The only other competitor to HPF's intake is the one equipped with cars that don't have this, perhaps that really elaborate, and relatively stock looking HPF CF intake. So the only competitor racing against itself is HPF. So, if they did release that previous intake that Chris showed us a few months ago, they are doing an amazing job of redeveloping and "optimizing" their CAI.

What's the whp gain for stage 2.5? :)

hopefully mine will be up and running in the next few weeks...curious to know as well

[HPF Chris]

I'm guessing the stage 2.5 customers will see a similar range as the stage 2 customers. It is possible the gain could include another 5 rwhp but we'll find out shortly.

P.S. Your motor is now out of your car and is ready for tear down. :)
