Php Airbox Dyno Results

[Smokie]

I visited Dennis Reinhart today at his new facility, talk about upgrading !!!! Those of you that plan to visit for the Grand Opening will not be dissapointed.

To get to the point, I drove 3 hours to shop and about one hour after arrival we did the base line run with my stock airbox.

Baseline: 283.0 HP -- 295.9 ft/tq

Steve (from Reinhart Automotive) installed PHP airbox, install was uneventful except for cross-threaded side set screw, Steve quickly ran a tap thru it and completed install.

First run PHP box: 280.1 HP -- 302.5 ft/tq

When I saw this I was not a happy camper, after further review Steve mentions my A/F ratio is pig-rich in the 11's and calls Dennis over, Dennis calls out instructions for a correction...and we run again.

2nd run PHP box: 291.0 HP -- 307.3 ft/tq

At this point I am starting to smile and I thought ...this is more like it...but upon further review my A/F ratio is now too close to 14, Dennis told me that we needed to add a little fuel to increase safety margin.

3rd run PHP box: 289.1 HP -- 304.6 ft/tq

After this we all agreed that those were the best safe numbers so we left it there, my final A/F ratio is about 13.2 average across the board. Below is a scan of the final result, caution the A/F results you see there are from the sensor at bung right before the x-pipe, highly sensitive and very spiky, the one at the tail pipe looks like a flat line right across 13 thru the rpm range.

Peak Results: OEM box 283.0 hp / 295.9 tq
.......................PHP box 289.1 hp / 304.5 tq

Net Results: +6.1 hp -- +8.6 tq

I would sincerely like to thank Dennis for his help, courtesy and excellent service...everything he told me; turned out exactly as he said it would. Also Steve thank you for the caring way in which you worked on my car !!!

PS: Pay close attention to what lies before the peak numbers and you will see some serious torque and hp gains, much more than peak numbers.

What air filter is that? :D

Hope they are better on you then they were on me.:cool4:

How they are better on you then they were on me.:cool4:I don't know the brand of the filter, it came with box with a very nice pre-filter wrap cover. I am unable to say why your results were not satisfactory, I did my best to produce results that can be considered stable and real world.

I can ask you this, did you have your A/F ratio corrected after install ??? Without this tweak, I lost HP.

[DEFYANT]

I'm just J/Kn, looks good to me.

Way to go Smokie!

I have one of those things but never knew if it mattered. And now we know.

Hope they are better on you then they were on me.:cool4:But of course....:P

Smokie did an entire intake kit replacement, NOT a drop in filter.

Anyway, Mr X., I am glad you have a good trip. I told you this would be a good looking and gainable kit. Don't fret those numbers. That's what we expect from these kits in the REAL world. I'm glad you actually saw results!

Here is where you're gonna notice the benefit.....BMS....take that headlight out as we discussed, and run that baby hard. I can't wait to see your new ET's.

Here's my guess: .2 tenths off your 1/4 mile et's. :up:

BTW: My homemade tube is almost ready. Guess you're gonna want one of those too.:D

I have one of those things but never knew if it mattered. And now we know.Thanks, I got out my reading glasses and a couple of rulers and found that at about 3500 RPM'S the Hp gain is about 15 hp and the torque gain is about 16 ft/lbs, this may help to explain the exagerated claims about increases in power made by some vendors that are upsetting to most people.

I could take the same results and claim 6hp/8tq increase or 15hp/16tq increase....sort of like pick what you like, they are both true.

Thanks for that very informative post. :bows: Too bad though, if i could respectfully add, that you didn't had the chance to test, afterward, the suggested spacer from that very same PHP arsenal. :confused: I would had been curious to see the combined result. :burnout:

I tested the PHP spacer alone and I am pleased to say that even in a supercharged application...It looks great!

Nice work Javier, I am pleased with your results, and your careful attention to detail. Thank you, and congrats on your real world gains. I all adds up.

I have the spacer, won it at Indy and it is part of my dyno results from Team Ford when I did new exhaust and pullies. I documented those combined gains in another thread back in October '04.:)

I all adds up.Thanks Mac, I am doing the best I can within budget to document what I do, also I could have bought the air box and installed at home and probably would have been dissapointed with results. For reasons that I can only speculate at, the air box changed my A/F ratio enough to lose horsepower and I suspect my gas mileage would have suffered also...the tweaking that Dennis did not only won me some ponies but maybe kept my fuel economy where it should be.

Some additional information on the PHP airbox. The air intake box (white plastic rectangle with rubber hose attached) for the suspension air compressor is mounted directly in front of air filter and interferes with the removal of the air filter.

I rerouted to fender well, drilled small hole for push-fastener and secured with blue tie to prevent rotation, I also added a rubber washer under the two air box mounts 1/8" thick; and finished the rear mount with a stainless steel washer.

These small changes improve filter access and removal greatly, to the point were cover removal takes about 30 seconds and filter removal about another 10 seconds, a wide blade stubby screwdiver and a 3/8 wrench is all that is needed.

At this point after some cool weather and cold starts there are no negatives to report, rest assured that if I have any problems....you will hear about it. So far everything is a plus, there is noticeable improvement in performance after install and A/F corection by Dennis.

Two items that I wish to address, my thanks to Barry for his advise and input in this matter, also to Petrograde.

Also to Dennis Reinhart for making sure that I got the maximum benefit from airbox. :)

Smokie....I just got a new PHP from Dennis as well on Saturday.....GOOD STUFF. The car runs great....I am going to get back up there to tweak my tune a bit...but I am very happy....and it looks cool too! :cool4:

Check out my post above about relocating the little plastic intake box for suspension compressor, filter will hit it making removal a PITA.:D

For those of us without access to any dyno tune facilities at all, I wonder if it's possible to install the Pauls cold air box ourselves, and then get a tweak from Dennis via email for the SCT 9100? Of course, with only a seat of the pants meter there is no sure way to tell if you are running too rich or lean or getting maximum output from the thing.

Guess I'll have to hold off, just as I've done with other mods, as my choices are either drive 6000 miles round trip or move to Florida. Did I say California sucks? :mad:

Regards,

Norm

Is the new air filter oiled? I have been thinking about changing the intake but don't really want to deal with an oiled filter. I would rather just replace the paper regularly.

Looks good :)

NormI am not sure that the airbox will change the A/F ratio in every case, it may have been a result of my exhaust and intake spacer. I would strongly recommend calling Dennis and posing the question directly to him, he sells the PHP box and knows the MM. quite well. Best of luck.

jtaYes is oiled, mine fortunetely was very lightly oiled, I used a K&N in the past for about 10k without problems.

Mine arrived so oiled it left a stain in the bottom of the box.....on the OUTSIDE!

It's been in nearly a year, and the last time I pulled the cover off, the oil was still seaping and had left a puddle in the lower box, and the cover was wet on the bottom.

It felt slippery like it was oiled but it left no actual residue on my hand. Have removed and checked twice since purchase. No oil at all in box or on the pre-cleaner cover that it came with.
