This air intake was released a few weeks ago, but they didn't have the horsepower gain listed yet. Well evidently they did a dyno and the information is now up. See below:<p><A HREF="http://www.knfilters.com/search/product.aspx?Prod=69-9000TP" TARGET="_blank">http://www.knfilters.com/searc...000TP</A><p>Click on dyno results link and check out the estimated horsepower gain.<br>14.61 HP @ 3900 RPM. Now that seems like very useable horsepower. Factor in a chip and exhaust and that number would probably increase as much as 5 HP. This looks good to me.<p>Let's hear from some of you dyno gurus as to whether this dyno was a good real life indicator.<br>

Re: K&N Cold Air Intake Horspower Gains and Dyno (jclaib)

more then I would think. I have my doubts, but I love to be proven wrong and get more HP, one good thing about the K&N setup is that it clears up the packed engine compartment, toss the battery in the truck and you'd be all set for a BIG turbo....

I just can't see how a filter on a stick can net that much increase. I suppose if they took the absolute worst run out of a bunch of runs and then the absolute best out of a bunch with the filter it might be possible.

Re: (TFS)

sorry but I do not belive that for a second. Hopefully someone here can install it and dyno.

Re: (TFS)

I mean....thats a little misleading. Yes as one point you do get an additional 14HP but overall it looks to be about 10 (even at the peak). Using K&N's methods, when I blew nitrous on my FMIC I got an additional 22HP at one point, but overall it was about 15HP across the board.<p>I like that we have some data to back it up though, thats always nice. Maybe Ill get one to (if they come down in price a bit) and compare it to my base Dyno that I got to see what the difference is. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Thanks for the link. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"><p>Questions:<br>Can you hear the turbo spool more easily now? <p>What type of dyno was this measured on? <p>Is the tube coated? If not it will transfer heat much worse than the stocker... resulting in less power the longer you run the engine hot.

Re: K&N Cold Air Intake Horspower Gains and Dyno (jclaib)

I'm impressed with the build, and the instructions. I'm not so impressed with the claims.<p>- 14.6 HP is relatively meaningless, a single point in time. The average is much closer to 10 even if you believe that.<p>- this is a single pair of Dynojet runs, and they don't show enough data to verify what gear it was in. The comment, in fact says "second", which is a bad choice even for the Automatic transmission as indicated.<p>- the date in the comments is November of 2005. Did they really have this pipe to test then? What <I>did </I>they test?<p>I buy that the pipe improves throttle response, and raises HP somewhat (maybe 5hp). I also buy that it opens up the front of the engine compartment.<p>In fact, I think these are good reasons to consider it. I'm just a little put off by the hype. Price is on the high side too but it's a new piece and one of a kind.<p>One bad thing - it's something of a hot air intake. The baffle opens into the space behind the radiator. I wish they had hooked up the existing snorkel somehow.<p>BTW, I am not too concerned any longer about exposing the ECM, since if you look at the stock piece it's completely open beneath that plastic cover now. I bet you could place that cover over it after installing, in fact.<p>Tom.

Somewhat of a side note. I noticed they're the first company to note the new design of S40 as 2004. I have a 2004.5, so i figured it would just be 2005, like on tirerack and every other parts site, but my registration is for a 2004 Volvo S40 T5, just interesting how most sites don't have it like this.<p>Anyway about the intake itself, if it comes down in price I'll pick one up in the early summer, I don't have a base dyno so that's the only problem, and now that I have the magnaflow muffler no true base readings.

Take something that's an effective insulator and turn it into a conductor and storage mechanism of heat... there is a difference. And a corresponding effect on the system.

Re: K&N Cold Air Intake Horspower Gains and Dyno (taintedintuition)

common sense says the increased breathing would show up mainly on the top end and not thru the range. Improving the air in front of the turbo does not make much more HP on a proper sized intake and this intake has more then double the surface area as a 1.8T VW. I've had both setups apart many times. Especially if we are talking a stock car, the turbo should have no problem putting out stock boost, so how can an air filter 'add" power. The only way to do that is making the turbo work slightly less harder (it is as stated able to easily make its designed boost) so at best you save a little on pumping losses and a little on the temp of the air (turbo doing less work to the charge)... comes out a few HP most of which is on the top end, but you will feel a slightly faster spool too.<p>should be easy to test just unbolt the maf / mas from the air box and see what it shows on the dyno

Re: K&N Cold Air Intake Horspower Gains and Dyno (V50_T5)

the curves IMO are too even, more like same car run in different gears.<BR><BR>
