We had some free time at the end of the day at the shop, so we decided to bolt on a K&N FIPK kit and the SLP bellows on my car to see what all the hype was about. We made all the passes through the Hooker catback, no shortbelt, etc.

(best of 3 runs for each mod)
Whisper lid: 380rwhp/373rwtq
added SLP "high-flow" bellows: 381rwhp/375rwtq
added K&N FIPK: 384rwhp/376rwtq

We then let the car cool for about 15 minutes and made 2 back to back pulls and it pulled 387rwhp/377rwtq. We attribute the few extra hp/tq to the car cooling off.

I didn't both printing the graphs since there was nearly 0 difference in any of them. Looks as if the FIPK doesn't show too much gain over a lid/filter setup. The gains could have been dyno variance as well. I think I'll stick with my lid and filter. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> At least the SLP high-flow bellows looks better than stock for the $50 bucks. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Just out of curiosity, we opened the cutout and did the shortbelt mod with the FIPK still in place. The car pulled 391rwhp/378rwtq! Looks as if the hooker catback flows VERY well. We then bolted the Whisper lid back on w/ stock bellows and pulled 390rwhp/377rwtq. Again, hardly any difference between the two setups on the dyno.

Just count this one up as a learning experience. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Jason,
good dyno info there! I think those dyno #'s really put that K&N FIPK hype to an end <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> When you dynoed the Car with the FIPK and witout it, was the hood open or closed outa curiosity?

thanks

Jack, the hood was up on all the pulls with a fan pointed toward the airbox/lid.

That's interesting results. Are you going to track test it also?

Damn dyno *****. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

Justin, I don't really plan on track testing it as I put it back in the box. LOL <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> I think Paul is going to try it w/ his SLP Ultra-Z hood.

Yep, I think I'm up to almost 60 pulls now. You still have me beat by a few. LOL Time to come test your 3" y-pipe and NAWWWWWWWWSSSSSSS so you can hit 70 dyno pulls. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Well just my $.02 cents worth here,to be fair to the FIPK, dyno numbers don't lie but they are static numbers and should not be compared to ram air effect. A fan will not direct as much air at the same velocity and tempature as will be present when the vehicle is in motion. Also to be taken into consideration is the total area of the FIPK filter vs the air box filter i.e, more area = more air. The FIPK has more SQ" filter area add to that the FRA and Ram hood = air velocity increase with accompanied air tempature decrease theoretically speaking more air, more fuel= more power. Dyno numbers are one thing track numbers are another. A lid alone can't compare.

I dynoed with the K&N FIPK today too.

Stock
299 hp & 314 tq

K&N FIPK
314 hp & 325 tq

I'll try and get some track times this Friday.

FUTURESTRADER

What am I missing here?

You state that the FIPK gains 4HP over lid on first test runs.

Then 7HP over lid on 2nd runs (you attribute this to cooler temps. Maybe, maybe not???

When you calculate Lid $120, Filter $50, SLP Bellows $50 = $220 Total

The FIPK is $279 ($259 on GP)but on every run it outperforms Lid, Filter, Bellows every time.

For $50 more, I gain at least 4HP more ($12 per HP) Cheap, and possibly 7HP more ($7 per HP) and the FIPK is CARB certified and superior quality.

Most lids have fitment issues, gasket problems, and bellows has cracking issues.

I will admit that I like the look of the lid better, but in terms of performance is the FIPK not superior to everyone that has tested it. I have never seen anyone test it and not get good results???

In terms of HP per dollar, is the FIPK not the better deal???

Thanks.

I just noticed in your last paragraph that you pulled 390rwhp/377twtq with Whisper Lid and stock bellows, is this a typo???

Your previous runs with Whisper was 380rwhp/373rwtq.

A difference of 10rwhp with same setup???

Please clarify.

FUTURESTRADER: As I said in an above post, the car has close to 60 dyno pulls on it. A 15 minute cooldown with the fan sitting on top of the motor 99% of the time is worth 3-4hp, especially if the motor was up to operating temp for quite awhile like it was making the previous 9 pulls. That is why I attributed the gain to the cooler engine temp.

I'm not bashing the FIPK kit. The fit and finish was excellent. For my current setup, I do not think I would see a gain with it at the track. This is all I care about. If there was a way to TOTALLY seal the FIPK to an outside air source (FTRA, FRA, ram air hood), I think it would show a slight gain at the track due to the increased surface area as Elite Hot Rod pointed out. I have no doubt the FIPK has the ability to suck in more air, but will it be cooler, denser air or will it be hot engine bay air once the hood is shut? I think the FIPK setup would work well on a car with a WS6 or SLP Ultra Z style hood where teh filter would be seeing cool, outside air constantly. I have a WS6 hood going on my car in the next few weeks, so I might try the setup again at the track when this is installed. But, for my current setup, the lid/FTRA combo would be better at the track IMHO.

The difference between the 380rwhp pass and 390rwhp pass was the cutout being open and the power steering bypassed.

Gotta love it.. the FIPK makes 4+ rwhp over a lid and its declared "the hype is over!!" lol.. Im with Futuretrader on this one.. For about same cost as a lid/filter setup you can get the FIPK.. which is CARB certified and such.. and EVERY time somebody dynos the car it provides a gain over their aftermarket lid setup.. Why do the tests if your not going to believe them "dyno varience".. lol

I will say i think the system benefits the SS more than the WS6 due to the fact that the SS ram air is not very effective (if hardley any) over the TA RA..

As far as the cold air deal ive posted the Autotap data.. the FIPK has PLEANTY of fresh COLD outside air.. IAT was about the same as outside ambient air temp.. Your never going to get air COLDER than outside air.. At idel IAT started to rise since there is no longer outside air being directed to the filter area.. Without the car moving the warm engine air flows foward and starts to be drawn into the engine.. As soon as the car starts moving IAT drops down to outside ambient.. the longer you idle the longer it takes to cool back down.. This is the same as a lid.. Warm air flows forward around the lid and warms it causing IAT to rise.. this take a little longer due to the insulating properties of the lid compared to the FIPK but it also takes longer to cool down..

FIPK phobia ~ it only gained 4rwhp over my current set-up.. and it costs about the same.. and its smog legal.. and it fits great = WHAT A PIECE OF HYPED UP JUNK.. lol

SSBoy

I think if a New ls1 owner was in the market for a intake system, then yeah he should consider the FIPK as an option.

For An ls1 owner who already has his FTRA with his Whisper/DirectFlo/MTI lid already on there, i dont think the gains will justify the cost, especially if were only talking 3 horsepower here.

If anyone still believes in "Factory Ram Air", then you have bigger issues than deciding which intake system to buy. There is nothing ram about, ram air on our cars.

Well in California one major difference is that the FIPK has a CARB # and the lid does not, all other thing being equal (which they are not.)

And that's my 2 cents used having both (see website in sig)

</font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">On my car it made +3rwhp from 5500-6000rpm, lol. The FIPK isn't a bad way to go as far as a dyno mod, but we all doubt anyone will see a gain at the track, and that is all that counts. Remember most of us already have lids, so we're talking about upgrading the lids to the FIPK, not starting from scratch. If you don't already have a lid, give the FIPK a shot.

If you spent the money on the lid system then stick with it.. but its good to have options and maybe this will drive down the price of lids (which are overpriced IMO)..

People keep saying they doubt it will show a gain at the track.. What is 5rwhp worth in the 1/4 mile??? Is ANYONE consitent enough to know for sure?? This is also a "your results may vary" type of mod.. when we dyno tested it (replacing the aftermarket SLP lid with the FIPK) we picked up 6hp across the entire band.. and 4rwtq across the same...

While the FTRA is a good air induction system I dont buy into it creating any sort of "pressurized effect".. you also have the radiator blocking and water issues.. plus a lid system with a FTRA costs WAY more than a FIPK.. But like I said it all comes down to having options..

FUTURESTRADER RESPONSE:

I appreciate the fact that you ran a dyno on the FIPK, the more the better. I purchased a New 2001 M6 Trans Am (Not WS6) in Nov 01, it is currrently in storage. I am about to start modding, and my first choice was air induction, so I have "NO" lid. If I had a lid I probably would not upgrade to FIPK unless I sold my lid, filter, bellows, FTRA, for a good price.

I have seen at least 6 Dynos on FIPK from LS1.com, LS1tech.com, CamaroZ28.com, and MFBA.org. No one has dynoed less than a 6HP increase over lid/filter, except your 4HP# which was done when the engine was at its hottest, one guy in fact claimed 12HP over Lid???

Just because an engine is cooled down does not necessarily mean higher HP on the dyno, In fact your first run with Whisper Lid was when the car was cool, and your best run was 380HP. So using that theory the FIPK gained 7HP over Lid. There will always be variances on a dyno, sometimes I have seen cars dyno the highest HP when they are extremely hot. I will agree that most cars dyno higher when cool.

I am not trying to start a flame war here, I just want facts? My only concern is HP and TQ. When it comes to looks in my engine bay I really don't care, Yes I would prefer a Carbon Fibre Lid, but when I am racing someone and I need every HP available, I don't care whats under my hood, "I Hate to Lose".

Since I am starting Fresh, I am going to order the FIPK, I think that Lid, Filter, Bellows, and FTRA will probably perform about the same, but I do not like the FTRA install and potential problems? Also, if I need to bring my car in for any warranty work I won't need to deal with uninstalling FTRA.

I called PACE today and they have the FIPK for $279 (GP just ended $259), they are backordered on FIPK but expecting a shipment this week, my name is on the list.

Aside from looks, I cannot find (1) One reason "NOT" to order FIPK. This Mod looks like the best "Bang for the Buck" that anyone can do on an LS1 engine, I wish all HP was this Cheap!!!

Thanks for your input.

I just bought my LS1 a few weeks ago...you can bet your @ss Im going with the FIPK. Where did you guys see a price lower than $300? I havent seen any GP's either. If you know of any, please let me know.

Needless to say I didn't upgrade.
