I believe racecougar has one. From what I've read, everyone seems to be quite impressed with them. I don't have any specifications on it though.

Stuff goes here.

I run a Moroso pump on my 5.8l.
I know this doesn't help you much, but I'm glad I have my pump....you can cool the car in the staging lanes.

Nick......................I'm back!!!
May you fly low and fast
rest in peace JL

Yep, I'm running the Meziere pump on my XR7. As far as I know, that is the only one available for a 4.6L DOHC. I'm completely happy with mine.

I haven't had a good dyno pull with the car since I installed it, but the Meziere pump alone has dropped my E.T.'s by a SAE corrected average of two tenths. That would equate to 15-20 rwhp, though it is only advertised to produce a 11 rwhp gain.

I have the same on my Mark VIII.

I don't think I gained 2 tenths but there was a gain in the butt dyno. By the time I got to the track with it I had a converter too, so the actual gains due to the pump itself were unknown.

I noticed they also advertise one without a pulley. Would that work on a DOHC as well with a smaller belt, or is the idler needed?

The idler is required to do the proper belt wrap in the crank, which is what turns the belt driven accessories like power steering, AC and alternator.

Is the electric pump something that I could install with the engine in the car? I will probably get one, but I don't want to kill myself intalling it

looking at mine (its on an engine stand) i can't see any reason why not but somebody correct me if i'm wrong. while we're on the subject of pulleys and belts, has anybody done an a/c delete on their car? if you were gonna do this you would need a differant belt anyone so you ought to be able to run a water pump that does not have the idler. thinking about it you could do a simple set up with the crank pulley, alternator, power steering pump and then a single custom idler, just a thought. a buddy of mine did that with a 3.8 he built. even went so far as to relocate the alternator.

The 4.6L modular water pump has got to be one of the easiest ever to change - in or out of the car.

Look at the belt wrap on the DOHC 4.6L and you will see what I mean as far as crank pulley contact. Without the water pump or dummy pulley on the electric pump, you will not be turning any belt driven accessory. Deleting the AC will not help. Most AC delete kits have a bracket and idler pulley in place of the AC.

The shrouded Cobra pump is a gain of about 5 RWHP over a stocker, so how much a gain you see with the electric one is really up in the air. After switching to the Cobra pump, I'm a little worried that next summer's temps may cause some cooling issues for me. For that reason, I would like more info on the electric pumps, but I can't find anybody who has had problems with them. I think they are good, but I need something rock solid since the Cougar is my only car.

Anybody have any issues with reliability on these?

Pete,

I have the Cobra pump from the get-go on the 5.0L. I think you will be ok with the Cobra pump. My car actually ran cooler home, than it did on the way down to Texas. I am considering the Electric pump down the road but right now I don't really see the need for it.

Usually, the big bore does run cooler than the old engine did, but I think that's common of the aluminum block. I'm not so sure though, since I haven't talked to others about it, but it makes sense. The aluminum will move more heat faster than the iron block will.

Here's another $.02...
The link on the Meziere site is here.
The install was VERY easy, as was the wiring. Just have everything you need BEFORE you start.
I've found my temps to be lower, and more consistant now, too. On little note, if you have underdrive pullies, you WILL need a shorter belt than stock, but this is mentioned in the Meziere instructions.
