- Today Was fun I went back to my roots of testing FREE POWER MODS For the Ford CROWN VIC LX SPORT known as Project UNDERCOVER!
I began by making a baseline pass using my #dragy then I went to work on the air box. once completed the density altitude had went from 1905ft to 26xxft. Did it gain HP?
for the last mod I did the famous TH-cam Crown Vic muffler delete while keeping the mufflers and tail pipes in place as the stock mufflers are heavy and I wanted the test to be as accurate as I could do .. The results of this test was a Surprise to me!!! Check out @latemodelrestoration Dyno test video comparing the Dorman vs Ford PI intake!

Good video Andy. I dyno'd plenty of cars that had exhaust upgrades done on them. Never saw a decent gain unless it was the last of many modifications. The thing that I learnt from that was until an exhaust becomes restrictive, it's not. You can't solve a problem that isn't there. The only gains you can get in an unrestricted exhaust, is from improving the cylinder scavenging, which is all dictated by what is happening in the front section of the exhaust. But you already know all of that. Looking forward to your future videos. Regards Greg
Yeah man! That's the best secret trick. Cutting the airbox gives the best breathing improvement for free. Definitely worth it. Screwing around with the exhaust is a waste of time and you won't like it.
My testing with removing the silencer on the air boxes I get better throttle response with it on there
Needs tuned.
Great stuff Andy! Looking forward to this series of videos and applying more mods to our 2011 P71 👍
I'm glad you enjoyed it! Im looking forward into turning this into a beast!
Andy
I enjoyed the testing and I will stay tuned sir

I've got a 2000 Grand Marquis. So far I've snagged and installed a Trick Flow upper plenum and ADTR ziptube. Throttle response is amazing! Next is installing the 2009 CVPI airbox I picked up for $35, a 90mm MAF sensor and a dual exhaust when I can afford it all with a SCT tuner from Marty's Spped Shop. Next year I'll be, rebuilding the bottom end the Manley way (crank, rods and 18cc Street Masters) and adding Trick Flow heads. Bad news is, as a mechanic, I'm a decent woodworker.
Good news is, I've got a friend with a 2000 Crown Vic who's teachinng me as we work on each other's cars..
I’m gonna start doing sorta the same thing on my 97 Vic within the next month.
Open up the exhaust and throw a Marty tune and get a explore rear end would move like a 96 impala
I would think having David in the car would be good for 40 horse at least! lol! thanks Andy...
I have an 03 mustang GT and the snorkel gets wider towards the air box but is restrictive at the end.. I cut it back a few inches doubling the size of the opening but retaining the reach out of the engine bay into the fender well.. With that small modification and a K&N filter is better than any hot air intake on the market and retains factory look.. I definitely felt a difference but it’s probably still under 5hp.
When I look at the pictures on E-Bay, I can see the difference. The one has tall intake runners like the original. The other one has the runners that are kind of flat on the top like the Dorman intake. The one with the tall runners ran just like the original Ford P71 intake. But they don't last as long as the factory intake
Look at the plenum lower side. Massive difference.
Andy I would try a KAM reset and see what it runs for a number. Throw a can of BG 44K in the tank as well.
I didn't think about that but I will give it a shot! Will be interesting to see what it does
Andy
Andy I could sit around ALL DAY with you and DV. The man that got me started use to race against Bill Grumpy Jenkins. Anyway my question is where do I put a balance pipe when tuning my exhaust
You may want to try the J MOD. TH-cam has a killer video.
The J mod is coming!

Another good mod is the nitrous mod 🤣 Jk jk
Oh don't worry... I'm going to hose it down!!!!

2001+ are improved so they don't require all of Jerry's original mods.
@@optimumperformance6998They can still benefit from the jmod. The jmod is more for longevity than performance.
I replaced that silencer with a piece of pvc & definitely felt the difference
That head liner is boss what model panther is that
I did the air cleaner trip to my 93 Lincoln it was worth it just to have the intake sound
They actually filter out 99% of dust and particles from 0-20 microns
@@randoboggsdeepin8803
What's that have to do with sawing off the snorkel?
I thought Ford fixed the intake manifold issue on 2002 and up 4.6 engines?
Never had an issue on the 94/95/ or 2002...
200k+
I thought those Factory mufflers what special mufflers made by a muffler manufacturer for quietness and horsepower Andorra maximum flow
I changed the box with a bigger opening and got a engine light on. I put it back to stock the light went out
You need a tune with these for many of even the simplest mods. Swapping a cvpi box on a civvy and/or a CVPI throttlebody will throw a code because it's reading more air than programmed. Even changing the axle ratio requires a tune, the electronic speed governor is set with the axle ratio and so is the speedo.
So little things are still little things. 😊 they can add up though!
They are small but they add up!
I knew I wasn’t crazy, I replaced the intake on my marquis and I swore it felt like it had less power afterwards, I knew I wasn’t imagining things
It's a very noticeable difference in power!
Thanks for watching

The resondator delete makes the car sound way better, I'm replacing these with FlowMaster FX... Us Panther Guys know this car will never really be fast with a 4.6... But the 'Cool' factor of caarruising in this big arse car is where its at :) BTW, I'll have the cold air mod done by next weekend!
When I'm done with this combo it will run 10's in the 1/4 with the 2V! It's going to be fun working on a 4.6 again

love live stream with Mr. Cope and plan on buying his valve body when its available
All right Andy :>)
Can you clock the TPS on these like the old 5.0s?
You can slightly.. I take a Dremel tool and elongate the hole! When you put a set of cams in a 4.6 I've found I can get it to idle clean by tweaking the TPS and drilling a small hole in the Throttle body.

Looking at 60ft times, the last was best, in worse air than 1st. So maybe picked up lower rpm power and lost up top?
Long tubes are about the only exhaust improvement at this point I'd assume.
Hi Andy, will you be installing the better intake manifold?
Most definitely!
Andy
So all you really gained was it sounds better? Love how everyone applies old school carburetor tricks to modern fuel injection. The fuel management system adjusts for maximum power based on available air.
Hiya Andy, I just ot a 03 Grand Marquis, practically the same car. Do you remember the under valance discreet ram air from the late 80's early 90's? It'll be a meatball job but I think I can make it happen. Also will be going with dual exhaust on mine, to reduce resistance from this single pipe one (was yours in this video single or dual factory exhaust?)
Lots of dirt down there
And sounds great
I've, never bought anything Dorman, that was any good. Especially, electronic! For goodness sake, don't buy Dorman cam phasers, for Ford 5.4, 3 V!
Oh I couldn't imagine putting Dorman Phasers in a 3V that doesn't sound good at all!
Andy
Let the people that make cars and rockets do what they do because that made no sense whatsoever. It's a small air intake. It's like a rocket that's small. At the end of it pulls air into one Pacific spot. If you crack it, break it now. Hot air from your engines pouring into it where it was no hot air from the engine getting into it. The tube was inside of the bottom of the headlight bringing cold air directly into the intake and this is the problem with the world. They believe whatever they do it's better. We'll break what we got and it's going to be better. You can't break nothing and make it better
I got a 100 send me a locker 😅
Nice seats, normally I see light gray or light camel?
I used to dislike those cars but they have grown on me. I'd like a black one with a coyote
I used to dislike them too but I look at them like a 4 door Mustang GT from those years

Andy
I'm confused, how can removing a restriction (stock muffler) in the exhaust system result in loosing HP? It doesn't make sense, replacing a muffler with a piece of pipe will result in less back pressure, and less back pressure should result in a HP gain or at least keeping the same HP it had with the muffler. There has got to be some other variable that caused the drop in HP.
But cutting the pipe before the muffler you are changing the length of the reflective wave. I do believe if it had a true 2.5" exhaust it would uncork it. These pipes are less than 2" in some spots!!
Andy
@@UnityMotorSportsGarageI was wondering what replacing the mufflers with straight pipe, to keep the full length ,would have done.
Four strokes don't need back pressure. What you're looking for is exhaust velocity. There are still four catalytic convertors to deal with. The only other answer I can come up with is lack of muffler has affected the ECU somehow.
Straight piping it will just make it sound like ass.
@@UnityMotorSportsGarage
Uncorking ? 281 cubes = 140 cubes per side 🤔🤔🤔
Not exactly restricted...
Try tube headers.
Under car turbulence increased major and slowed it down.
Great video Andy, I did that on my Lincoln town car the air snorkel was so small in diameter it be like us trying to breath through a straw. Tho on the Lincoln they pull air from in front of the wheel well. So I opened up the bottom area more. You could go one step better on your air box and get some of the self stick sealing foam from one of those home improvement stores and completely isolate the air intake from the engine bay.
I like that idea! Thanks for the tip..
Andy
K&N made a cold air system that boxed in the air filter and made it draw thru the headlight...actually works...ask the man who owns one...most important mod for the vic/marquis is at least a 3.73 gear...with a posi...and a free flowing dual exhaust...if you check the size of the tailpipes in the stock ford exhaust it's choked down to like 1 1/2 in the bends over the rear axle...
I agree real exhaust would help.
And uh...the only place with a tune for the computer THAT ACTUALLY WORKS is Mo's speed shop in Dallas GA...mustang guys just told me to get a mustang locally...I told them that the marquis had something a muttstang would never have...a backseat I could schtupp their moms on...

But the cars came with 235 horsepower. I'm assuming the aftermarket intake is killing the numbers. Before you do anything else that our car buy an intake. To see if the other mods you made help with the new intake
The factory rating is rated at the Flywheel.
Thanks for watching
Andy
The civy cars excluding LX Sport came with 235. The cvpi came with 250 04/05½+ due to certain engine parts and tune.
Son's 97 f150, shaped a piece of 3 in PVC pipe thru fenderwell , picked-up and swapped out intake elbow for PVC, this also helped.
PVC gray industrial conduit has sweeping turns!!
You can use HVAC ARMOR FLEX to seal the air box to the radiator support
Or a pool noodle will do the same.
The armor flex was a better idea its way more durable, Still thanks for idea!
Tossing that engine cover is a free mod that’ll keep it from holding heat over the intake.
Right In the trash can... 😆
Andy
Yes
The intake manifold comparison could be a red herring. There were several versions of the intake manifold. There was a recall for coolant leaks and some other issues. The various intake mods that use Mustang parts will improve the performance in small steps. An extrude honed Ford Perfomance/Motorsport version of the Police Interceptor intake historically makes a huge improvement after the air intake tract upgrades. Gets closer to a Marauder
I am on the lookout for a good Bullitt intake off because once the Trickflow heads and all of the stuff I have planned for the car it will need it. The Factory PI intake becomes a restriction around 320 rwhp from all of my testing
Thanks for watching
Andy
No there isn't several intakes. There's the NPI intake and the PI intake for the 2v. The FRPP intake is a PI intake.
Why spend $500 to extrude hone anything?
It's still 281 cubes.
@@hotrodray6802 to improve performance and have factory fit and finish.
II thought the K and N filter will spit oil on the mass air meter.
If you over oil them they most definitely will!
Andy
I had a new one that screwed up my Fox and got dirt all through my intake. Have detailed pictures to prove it. I'll stick with Fram. Less power but less dirt.
JMO
Regarding your Ford Crown Victoria, If I were you, I would try to imitate the Crown Vic Police interceptor calibration. You already have the dual exhaust. The next step would be to change your axle ratio to 3.27 or 3,55 . Then, substitute the powertrain control module from a Crown Vic police interceptor. This may require the installation of matching fuel injectors. Replace the MAF sensor and air cleaner assy with one from the police interceptor. The Crown Victoria police interceptor also uses a lhigher stall speed torque convertor, so you may want to change that as well. I spent more than 40 years working at Ford Dealers. Would like to talk to you about this sometime.
Lmao 😂
Kia forte's have a very restricted intake tract and he made a 4 inch inlet out of drier duct to the airbox from a opening in the bumper. He said that the fuel economy went way up. Performance stayed similar. He kept the mod because it was cheaper to drive.
I put that same tube without the resonator boxes on my Lincoln and a high flow filter and it definitely has a lot more roar under load
My GM is sure not quiet like my Signature.
Im really loving this, i have a stock 98 npi mustang gt, i want to get some more performance out of it. So keep it coming, great job Andy!
Get PI heads, cams n intake manifold n you'll be making close to if not more than 300hp.. On your npi block your pi top end will bump up your compression..
Yes same here. This content is perfect for me. Gotta 98 gt and 03 grand marquis. Keep it coming.
If you do the PI intake and cam swap you will get most of the gains of the swap. The PI heads themselves offer little power. You do get a nice bump in compression though on a NPI shortblock.

Andy your videos are great.
You speak very well on camera

I did always want to wrap my intake tubing in heat reflective tape like Ford boss did
That works! Also pulling the intake off and putting on both the valley of the engine block and bottom of the intake helps prevent heat soak!

The most effective basic mods for any Panther car are gears and a tune. Specifically 3.73's or 4.10's and a custom Tune by Marty Ochs of Mo's Speed Shop in Dallas, GA. Neither really increases power output BUT combined those two things really wake the car up and make it much more fun to drive. Anything, and I do mean anything, other than those two things would be a waste of your time and money. The only exception MIGHT be a 03+ P71 airbox and zip tube as well as a P71-style dual exhaust (for cars that don't already have those), but even that is probably negligible.
my 2001 merc grand marquis runs good, but not much acceleration with 2:73 gears. on the highway, it runs pretty good. thanks for the video Andy!
Yeah my first Vic had 2.73 gears... Horrible 😞 so I put a set of 4.10's in it lol

Port the throttle body elbow for a solid 10 hp gain. Might as well port the throttle body too.
Okay so as far as the airbox goes; the Maurader and 05½+ CVPI airbox supports just over 500 horsepower. There's no need for any of those trash aftermarket intakes, unless you just want more whooshy noises. Last I checked; ADTRs Rocket Couch is still using it. The best and basically only worth while mods, other than opening the box up, is a straighter zip tube and heat protection. All factory air boxes are cold air intakes, aftermarket ones aren't magic and make the air colder.
The problem with the Doorman intake is; it's a NPI that's poorly cast. The FRPP intake is just a PI intake. The main failure point of either is the coolant crossover tube.
You can get an 80mm throttlebody from Mustangs and Econolines, possibly Mark VIIIs and Continentals, too. If you have DBW, I believe it's Econolines and Expeditions- I forget.
At some point you might as well get a CVPI computer because enough of these mods will require a tune to work right. Quite a few things will need a tune, like changing the axle ratio.
Also Civvys, exc the LX Sport have single exhaust. The LX Sport has resonators, the CVPI does not. Neither does the Maurader. The CVPI also has stainless steel exhaust.
A Civvy might, MIGHT be able to use a CVPI aluminum or metal matrix driveshaft. If I recall; only the CVPI, Town Car and Maurader use the long tailshaft 4R, so it is shorter- as far as Panthers go. I do know the F150 also used the long tailshaft 4R.
TC are longer wheelbase. 3" and 9" depending on model.
@@hotrodray6802 I don't know what that has to do with anything I was saying. Yes the Executive Series and P72(Taxi) have an extended wheelbase that makes the back doors three inches longer.
Casper is also a work bench!!! Great stuff and FUN stuff Andy !!!
That is right! CASPER the Multi-tool 😆

I noticed the intake as well. I bought an e-bay intake for my P71 and it worked great. I bought another E-bay intake and put it on my other P71 and I lost power above. It fell on its face above about 4 grand. I noticed the runners were flatter on the second one I had bought. The first one I bought had taller runners similar to the original Ford intake. They were both $135.00. I went and bought a factory Ford P71 intake and haven't had a prob since. But it was $315.00 lol. Big difference. The E-Bay intakes seem to last me about 2 years before they have to be replaced. It evens out in the long run. When I replace the E-bay intake on my first P71 I will just go to Ford and get an original. Longevity is also a concern.
It's weird you are right it feels like it hits a brick wall at 4000rpm! I'm already on the search for a Ford PI intake
Thanks for watching
Andy
If you look on e-bay and see the high runners it will run right. I don't know how to pist a link to it. I've bought a few now and they are $135. Type in 4.6L 2v I take and it pops up in the first spot with the tall runners for $98. It will not last but about 2 years before it leaks tho.
It runs just like the P71 intake. They have gotten cheaper.
I think I would have put some chicken wire mesh over that hole to stop large objects from entering the air box!!
Always do my friend I usually get hooked up to the end everytime.
Great video, can't wait to see what the Crown Vic will do!
I just ordered a bunch of suspension parts for my 09, P71. I'm sure you already know that the tune makes all the difference with one of these engines.

My GM rides bad enough. It's no Signature, NVH.
The intake thing pissed me off too. Can you maybe help me figure why I can't powershift my 98gt after putting 4.30s in the rear? Lol. Now the belt tensioner shatters in a single pass.. with 3.27s it held up powershifts for years
Those gears you got will help a good bit paired with a sct x4 tuner would wake it up, it might not be fast but more fun to drive. I guess if you really wanted to get faster for cheap you would buy a eldelbrock victor jr and a nitrous kit and a stall converter. Or maybe a on 3 turbo kit for 2600.00 anyway nice video see ya in the next one.
Andy,
Go with the OEM intake manifold. Install a 04 and up CVPI air box, intake tube and a 80 mm (Mercury Marauder if you can find one) mass air flow sensor. You will need a tune to make it work. I did my 03 Sport LX 15 years ago and it made a big difference. On the Michigan State Police test, the 04 CVPI (250 hp) ran .6 seconds quicker to 100 mph over the 03 CVPI. The factory exhaust system is actually quite efficient since they redesigned the mufflers back in 1992. The higher numerical RAR will improve acceleration, but you will have vibration from the driveshaft at the end of the 1/4 mile if you are at 90 plus mph.
Some work and some just make noise, back pressure loss on the exhaust?
All back pressure is bad. Removing it usually requires a new tune on any engine.
K&N filters only filter cats and dogs. Fine for racing but bad for street unless engine life does not matter to you.
Not exactly, D.V. has a video on that. I have many thousands of miles off road. no complaints...
I had bad oil and dirt passage problems from a new KN. Went back to Fram paper.
@@hotrodray6802 so from no filter to plugged from the factory. Best bet is to used a OEM filter if your using the stock air box as they will fit and seal properly. If not use the filter that came with the CA kit your using and hope for the best.
off road in what environment? If in dusty or sandy conditions the engine is junk for sure @@wlogue
They actually filter out 99% of dust and particles. From 0-20 microns.
Wish the big ole Ctown Vic came with 351W
take off that steering wheel cover, they ruin steering wheels
The Crown Vic is ok... If you like that body style and want more HP stock, go with the Mercury Marauder! 4.6 DOHC....You can get plenty of power from them with the right "tweaks"
For me the Marauder is ok... But the price difference is a big deal. I picked this '03 LX SPORT up for $5500 and Im putting Trickflow heads and doing a 4.6 budget build that will make WAY more power than the 4V Marauder and be cheaper.

I have a 1996 Ford Thunderbird with the same motor and I bought a K&N air filter and I wish I would have just stayed with the factory. Now I got to figure out how not to pull hot air in the motor. I did see a little bit of throttle response but I got to figure out another setup to where I can get cold air coming into the actual cold air intake instead of just having my cold air intake suck in radiator Heat. However if I want to I can punch it and get 7.5 seconds 0 to 60 which is a whole lot better than when I bought it doing about 9 seconds
Nice! Objective testing. The gears will be a hit, hope those go next. Listening to that 1 - 2 shift was almost painful, that relatively small engine pushing that heavy car down the road with pretty tall gearing I suspect (2.75 or so?). I give that little cammer credit for pushing that barge around as well as it does. I remember the days of 400 inch smogger engines that were making 185 HP so this thing's doing alright.
It's horrible... Bad, thing is it has 3.27 gears. It takes FOREVER for the 1-2 shift!

I wish Ford would atleast have preserved the Town Car and built it past 2011. I know there were structural upgrades were necessary to meet NHTSA and DOT standards. While they were at it, shove in a 5.0 Mustang engine, a new 6 speed automatic and Stability Control
Regarding the Dorman intake, when I was researching it to replace my OE 2005 intake (cracked heater nipple, of course) I read that the issue is that they used their older 4.6 design, which was actually an improvement on those engines, mated to the later intake port design, but of course Ford had also improved the entire intake along with the ports. The video you included really shows the difference - the older intake design is more optimized for hood clearance, so tighter, smaller, shorter runners, and a smaller plenum makes for less flow. I ended up getting a Motorcraft OEM replacement intake, in light of all that.
Thanks for sharing, My take away: Ford Pays A dozen Engineers $300k a year to design Great cars. Some 18 yr old kid making $12 dollars an hour, thinks he knows better and ruins it.
I OWN A MINT 03 4.6 EXPLORER, ENGINE WAS REPLACED WITH A NEW ONE BY THE PREVIOUS OWNER, AND HAD A FEW 1000 MILES ON IT WHEN I BOUGHT IT. FIRST MOD I DID WAS REMOVING THE MAIN MUFFLER, IT IS HUGE AND HEAVY, DON'T THINK IT MADE MUCH OF A DIFFERENCE POWER WISE, BUT NOW IT SOUNDS BETTER THAN ANY V8 IN TOWN, AND MANY PEOPLE ASK ME ABOUT IT. BEST MOD I DID WAS FITTING A BIG MOUTH HOOD SCOOP THAT RUNS 2 AIR HOSES TO THE FACTORY AIR BOX, TO THE FACTORY AIR INTAKE, AND MADE THE ENGINE MORE RESPONSIVE AND YOU CAN HEAR IT BREATH WAY BETTER WHEN YOU FLOOR IT, LOOKS GREAT AS WELL, AND YEAH PEOPLE ASK ME ABOUT THE SCOOP AS WELL, JUST BY LOOKS IT IS AN IMPROVEMENT. IT IS STILL SLOW, BUT THAN AGAIN IT IS A SUV AND HEAVY. I HAVE BEEN THINKING ABOUT FORCED INDUCTION, AS IT IS STILL THE BEST BANG FOR YOUR BUCK, A SMALL TURBO AT LOW PSI (NO MORE THAN 6PSI) IS STILL THE BEST WAY TO GET POWER OUT OF ANY V8, SURE YOU WILL HAVE TO MAKE UP YOUR OWN KIT, BUT THERE ARE VIDS ON HERE ON SIMILAR FORD ENGINES HOW TO DO IT. THE BEST MOD I DID FOR MY EXPLORER WAS THE BROWN WIRE MOD, AT LEAST NOW MY EXPLORER IS REAR WHEEL DRIVE ON THE STREETS, PUSH THE 4X4 BUTTON FOR OFF ROAD USE. I WISH THERE WAS A BOLT ON SUPER CHARGER KIT FOR MY EXPLORER, ALTHOUGH COST VS TURBO IS WAY MORE.
Did you get an enginr light after the alteration. I know if you seap a civilian airbox with a police interceptor airbox and tube you can gain 5-10 hp but you need a tune after wards adding duaks to a civilian vic will also gain hp both police airbox and tube and duals will get you to the 250 hp that police crown victoria gets.
Andy I just got this video here and let me tell you it was very interesting and informative for me, thank you for your time. And I got a question. I got an 07 town car signature limited, I got a set of mufflers from a 15 mustang GT that I've been wanting to install, I don't want it to be loud and annoying, I just want to be able to hear some when I get on the freeway , do you think it'll be to loud or should I just delete the rear cats. Thanks again brother.
I'm at 800 sea level and my bone stock p71 crown viic runs 10.56 @ 69mph on draggy
when you did these tests, did you take account of using same road and checkpoints, wind conditions, and temp?
One suggestion would've been to do 3-5 runs at each setup and take the average of the runs.
Hint: Any air filter you can see through lets dirt through. 4:14
Right on
Thanks for watching
Andy
Great cars. I was a cab driver for ten years. All the cabs were old cop cars
I have the thunder bird 95
Andy, you think a stock CV is slow?? I had an 87 CV wagon with a stock 150 hp 302. THAT was slow! But my 76 LTD wagon, all 5000 lbs of it, with a 400 2V, was even SLOWER! And my 81 Fairmont wagon, with a 200-6, was worse yet! School buses were eating my lunch!
I had a 77 Squire 460 that was barely better than my 73 400.
Ran 0-60 in ten flat with just me in it... But was super comfy and quiet even with the horse trailer.
Comen sense
The engine Should have responded with More HP after these 2 mods.....Maybe the Baseline should have Included reading the WOT A/F ratio.....it's Possible the Ecu changed the A/F ratio & Reduced engine Hp.....
Don't these newer ones run closed loop at full throttle too?
It takes more than that to get real noticable gains with a 2v, especially a Panther with its ECU. I can't remember how the ECUs work, but they don't use the MAF as the main factor, if I recall, I think they're based off speed density.
