400Hp

If the unibody minivan can handle this well then shurley......

Is there a recommended aftermarket E fan kit or do people bolt on junk yard fans from other cars? Which application would work for people who tow?

Well, you have 292 crank now, Intake, Exhaust, E-fan,T.B, underdrive,Syn fluids and a flasher tune might get you to 335/340.
NA I would think thats about it.

Try the Flexalite 188 fan I believe, the one with no controller.

Or How about a volkswagon beetle with a jet engine http://ronpatrickstuff.com/ But serious this is pretty sweet!

The least expensive way to make 400hp on these vehicles is going to be a supercharger. I'd recommend a Saleen VI.5 or the less expensive and more inferior M90. Either will get you there. The Saleen is a better unit. It can do the same power at half the boost of the M90. The M90 will cost way less and I love the sound of the M90. To me it sounds like a Lightning M112 but it reaches the "scream level" quicker because it's smaller.

The M90 will not do it, that is way too small for a 302. The OEM M90 Saleen Explorers only made 285hp, maybe 260rwhp IIRC. That's low 6psi or so, but with no ability to cool the mixture much, it's bad. You might fight it to make 300rwhp, but that's too much money and effort.

These trucks are all needing new engines soon. Why not budget the typical cost to build the stock engine, and add to that what you can for power gains. Invest money into a really nice set of heads, intake, and custom camshaft designed for the vehicle.

You can get those for about $2500 if you don't waste money or go cheap with an OTS cam. Those can gain you 100rwhp if done right, which will beat the awful M90 Eaton blower. If you step up and build a 347 to go with the special H/C/I, expect 400rwhp if it's built properly.

Maybe I am mistaken but I thought that the OP had a 3rd or 4th Gen X with the 4.6 V8? Though the M90 would be on the small side it would max out right around 400rwhp on the 4.6.

Also didn't the Powerdyne BD-11A centrifugal supercharger come on the supercharged Saleen XP8's, not the M90.

Psyc has a decent point with the Saleen TVS based blower for the 4.6 X if you want something that is a good kit, doesn't need much to adapt, and the blower itself is pretty efficient let alone having an AWIC to keep IAT's in check. If I were shooting for right around the 400rwhp mark in a 4.6 X that is probably the series of blower I would go with. No need to get into the bigger Kenne Bell or Whipple blowers at that power level.

I'm sorry I didn't go back to the beginning to see what engine the OP had.

The Saleen XP8(98-01 302 Explorer) had the Eaton blower kits as an option. I'm not sure if the Powerdyne blowers were an option for the XP8, but yes I've seen a few of those too. I'd say the Powerdyne would have a better chance at making 400rwhp than the small M90 Eaton.

For the 4.6 there are more options because there were more kits available to be able to adapt something to the Explorer. An M90 is still too small for those, it will do better I'd guess, given the limited success Alex had.

Alex had a blower similar to the M90 on his 2002 4.6 Explorer. He didn't quite make 400rwhp IIRC, but he had added additional air inlet cooling, and several other support items. He had a bunch of money tied up in that engine combination, plus the actual engine wasn't stock. He got about as much as could be expected from the smaller blower design.

In the end, it seems much wiser to begin with a blower sized better for the intended engine and power levels.

Alex was starting over with a different larger blower kit, plus different(TFS) heads and cams.

Don I am almost 100% positive that the XP8's that came supercharged had the Powerdyne BD-11 centri blowers and not the Eaton M90 blowers. I know that there was one of two people who swapped from the BD-11 blowers to the Eaton M90's but they didn't come that way from the dealer.

While an M90 is small for the 4.6 2v engine it still will make just shy of 400rwhp which is what most people want. The AED kits became a bit more popular with the 99-04 Mustang GT crowd and there were many that were making right around 400rwhp on stock engines or near stock.

Alex's issue was that his combo was really mismatched. He was running a big bore engine displacing roughly 302-304 cubes ported heads and cams, from what I remember, and an M90S feeding it. Of course the choking point will be the blower at that point. You are only as strong as your weakest link. That is still not to say that the blower itself is not capable of producing right around or just shy of 400rwhp in a near stock 4.6 2v combo.

Whether it is wise to go with a bigger or smaller blower in the beginning completely depends on the goals associated with the project, and the timeframe for said goals. If the total power that the person wants to make is only 350-400rwhp in the end then there isn't need to go with a blower that is capable of supporting 600 + rwhp. Chances are likely the bigger blower will cost more and if you aren't using the extra potential then you are wasting money. I see this same mistake occur with the 03-04 Cobra guys and the 07+ GT500 guys who go with a huge Kenne Bell or Whipple blower and don't end up pushing it even remotely into the efficiency range for the compressor. Wasted money and less power per psi boost than if the owner had went with a better matched system to their combo. As I said before, the M90S based kits will support right around 400rwhp so they are a viable option if a person see's a used AED M90S kit for the 4.6 2v for sale. However, if you are buying new and still want to stick with the 400rwhp area then the Saleen Series of TVS blowers would be the better choice.

We have a guy on the www.mysporttac.com forum. He has a stock 4.6L 3v. He makes 433rwhp with an Roush M90 Gen 4 blower.

Oh, and his sport trac is an AWD.

His blower is maxed at like 8 or 10 pounds of boost. I forget what he posted.

Yep, stock for stock the 3v's will make more hp per psi boost than a 2v will. I am not too surprised to see an auto 3v putting down a little over 400rwhp with an M90. It's a nice comfortable amount of hp that is nothing insane but also provides enough oomph to get the truck moving pretty well too.

The more I learn about these 3v 4.6L the more I love them. They can do some amazing stuff! I'm hopng for 430 RWHP (front shaft disconnected) but i'm considering omitting the Cams and BAP from my setup. That would put me between 370-400RWHP.

The problem with the cam upgrade is that it brings be beyond the threshold that my fuel system can handle. I'd the BAP and the install labor on all that brings the total price for the Cam upgrade to over $1700 with tax. So is 20-30hp worth it for $1700?

If I were you I would take things one step at a time. Enjoy it with just the blower on it once it is installed. Then maybe later if you feel the need for more power then upgrade your fuel system and cam it.
