Yes that is the web address.

I never seen that offered before. If I were you I would call them first to ask in person. Sometimes people will have items listed on their site as offered for a vehicle when in actuality it is not.

I understand staying basic. Throwing tons of words around can get some people confused. Just make sure when you do try to keep things basic that you explain them correctly.

well, so far ive gotten the same message by both phone, and Email for that supercharger. it comes with everything needed to install and mount, and is only for the 4.6...sounds legit, but maybe this warrents further investigation.

 

[zerodevil]

well procharger makes a supercharger for the 4.6L f150...but im not sure how extensive of a modification to an explorer it would be. Ive begun saving up to buy the supercharger, ill do what i can after i buy it to make it work...might have to move some things around under the hood, and might take a new throttle body and or radiator....still tryin to figure out what to do with that cat....im not sure if that big cat under the driver door has an O sensor in it or not, so my car might be running too rich or lean if the cat is malfunctioning...but if it wont...i might just cut that whole cat out and get a pipe...still have two cats welded onto the down Y pipe....any thoughts people?

The Explorer's share the same front engine cover as the F-150's so that Procharger will probably not have to be extremely modified to be fit onto your truck. Probably just a few simple relocations or items and you should be in business. Nothing insurmountable.

The only cats you need to retain are the front one on each pipe from each cylinder bank and the length of pipe far enough back to keep the rear O2 sensors in there to read for emissions. Eliminating all the other crap behind that will not throw any codes.

awesome

im having the cat cut out and a pipe welded in this friday, and im now saving for my procharger. one more thing, are these spark enhacers ive head of worth doing? ive heard of gains of 15 hp. what about the ones that james has at hensonperformance?

I've looked into the same things and if you are going to spend the money on a set of COP's, I'd go with the granatelli's or the MSD blasters. You can pick off the MSD's on ebay for $384, and the Grantelli Pro series are about $480, and the Hot street model runs $260....One has a blue coil the other a red. Both can be seen on their site. From what I've heard, they are worth the money.

I can tell you one thing, I just installed a custom ported and polished trick flow upper plenum and have been nothing but smiles. I got a lot more throttle response and a lot better pull up top. Definately a good inexpensive mod, I think a stock out the box is dyno proven to gain around 7-9rwhp, where you might get a few more with a custom port and polish. I'm selling a custom ported and polished throttle body if you're interested....check the for sale section, I posted pics also to give you a better perspective of the difference between stock and custom.

Focus on the supercharger and its costs first before heading towards other upgrades. The more you keep your mind on one single track for now the quicker you will reach your goal; and do so with the least amount of headache and rework.

Upgraded COP's do have their advantage but I would suggest that you hold off on them for now.

Hey rocket, is there anyone else doing what allenengine.com as they seem to be out of business??

I just stumbled upon that fact about a week or two ago when linking someone else to their site. That is too bad. I do not know of any company making specific roots supercharger kits for the 4.6 Explorers at this time. There are others that can be adapted with some effort but they will not be drop in kits.

 

[zerodevil]

lol

well just an update,

I had the bad cat cut out and a REALY high flow cat droped in, and im still searching for a feasible supercharger. Id like to go with one that offers a PT warantee as well. I have been looking for one of these used Allen superchargers and im having absolutely NO luck what so ever. Id like to go with a roots style, any good recomendations?

 

[ktford]

Being here in Australia, I'd of love one of you stateside fella's to track down the allenengine dude and see if he's got any stock left, otherwise whipple offer a kit for the 4.6 stangs's.
One question is, do we know how many valves we have in our cylinder heads, some of the stang's sent to Oz have 32, some 24 and then I believe there are the older 16 types about as well, so me wonders how many the Xplorers have, as elsewhere I've read that X's run a alloy block unlike the cast ones in the musty's

I only get on peoples cases when they say really stupid things.

I agree, the dude said something SO far from fact, that it's not funny.
The last thing you need is some idiot spreading faulty information....someone's gotta set him straight,



Bolt-ons.....? Dont even waste you're time, the gains are SO minimal, its usually not even worth it. You'll REALISTICALLY see 2-5hp from a CAI, and about the same from Headers and Exhaust seperately.
(i HATE when people use ricer math)

If you get a nice custom flowing exhaust, lose the cats, you might gain 10hp or so, but theres TONS of variables that can affect HP, theres really NO WAY to tell how much you'll gain, unless you run YOUR TRUCK on a dyno, because you can have 10 people with the same car, and you'll get 10 different dyno numbers everytime.


If you go with a Turbo, its gonna be a completely custom project, you might be able to find a turbo kit for a Mustang GT, and just swap it over to your truck, but im not possitive.

Your best bet for HP, is to ditch the bolt ons, and just get a supercharger, and custom tune, and custom exhaust system.

These people make a IC'd supercharger kit for your truck i believe.
http://www.aaxel.com/Merchant2/merc...&Category_Code=al_supercharger_explorer_02-04


It only puts out around 6 PSI stock, and you'll still need a custom tune BEFORE you run it, but you can always get a different pulley or upgrade the injectors even more.
(im not sure what this kit makes for sure, but they do make it!)

There may be different supercharged kits you can put on your truck, im not possitive, but this one appears to be a bolt on kit specifically for your truck.



And if you REALLY wanna save money and make big power, you can always go on juice!
Nitrous is a tricky one......if you've never installed or operated it before, you need to find someone that HAS!
And when I say find someone who has used it, I dont mean joe blow the idiot ricer that lives down the street that THINKS he knows everything about everything....
If you cant find anyone, just make sure the kit is installed PROPERLY, not just ghetto rigged on there, because thats a surefire way to have a blown engine.
Also with nitrous, you need to inspect the system everytime before you use it! Cause if your throwing a 150shot, and you get an uneven mixture, you're about to lose an engine.
I probably wouldnt risk nitrous without having forged internals......but you can safely run nitrous on any engine, you just cant exceed what the engine can tolerate, other wise, youre gonna have way shorter engine life at BEST!

I see...

a centrifugal charger (sometimes referred to as a "procharger") is shaped like a turbo but is still operated thru a belt (thus, being a supercharger)

a roots or twinscrew is mounted ontop of the engine block and bolts rite above the intake... they have two huge screws (thus, twinscrew) and can push much more boost than a centrifugal because of the changable pulley and simply the volume of the piece

Procharger is just a brand of centrifugal supercharger. Other brands of centri's are Vortech, Powerdyne, Paxton, as well as some others.

The roots and twin screws do fall into the positive displacement type of supercharger arena but are different from one another. The twin screws have actual screws that pull air in from the rear of the blower case and compress it while projecting the air out of the bottom. A roots has lobes on rotors that accomplish a somewhat similar method of compressing (moving) the aircharge. The roots compress the aircharge in a similar way but different manner than the twin screws which makes the TS's more efficient due to this difference.

You all are in different states also... I think we had a discussion at one point about "Engine" v. "Motor" I see these are small issues that are so blown out of proportion that the point of the thread gets buried. What is a product name in one state may be a product type in another...

And everyone says things that are incorrect from time to time. A correction is fine, but "idiot" "setting straight", again the thread gets tangled.

1_v8, there are people here that can "correct" everything you've said, that doesn't take away from you. For peeps like me that don't know about what you all are talking about, it's very interesting to read. But the name calling is :thumbdwn:

And for all that Bigapple has contributed to this board, a little more respect is due.

i appreesh the backup... ive given up on talking in this one... my facts may be misconstrued at times but rather than saying im an idiot, i think calling me out and supplying me with the correct information without all the insults would be more suitable... but whatever at least i was corrected

From reading, it seems that you both helped the poster tremendously. Personal attacks on you, not even necessary - It wasn't Rocket, just for the record. This thread could use a little cleaning up.

It's a public forum, this is the results. Doesn't matter if its a cell phone forum, computer forum, explorer forum, mustang forum, LS1 forum, you will always run into these problems. The task is to FIX these problems by not being rude, but being factual and helpful.

It's a private forum... members only. But you are correct, being rude is tasteless and we can't address issues by mocking other members. BA and Rocket are like top-tier members, they contribute too much to have either say they will sit out of a discussion -
