Wile the engine is out of the SE350, I'm making a few other
"refinements". One of these refinements is the addition of a 10" cooling
fan for the engine bay. Horsepower makes heat and it get's HOT under
there . I'll set up a low temp coolant sensor system duplicating the
rad fan system to activate it.

This is the adaptor ring that the fan will mate up to.

get some side scoupes and a mustang scoupe for the deck lid too, i have my rustang scoupe, but havent installed it yet, , what kind of fan are you using,
your plan is to blow in cool outside air, but you need one somwhere else to blow OUT the hot air

Hmmm ...looks pretty close clearance wise...
are you sure your going to be good in that department?

BTW I mounted my fan that way.

(passenger side)

With the 383 and 350 in Raptor, I didnt really have any cooling problems. I drove it around in traffic all summer. Stayed at about 175* all the time except up to 220 in bumper to bumper traffic. I just used some louvers in the lower quarters, used belt water pump.

I'll be using the same fan as Tina showed in her sewer grate mounted one (great minds think alike) . It's from Summit, part # PRM-19010. I don't recall exactly at the moment, but it puts out something like 700+ CFM. It was the highest volume of it's size I could find. Actually I concidered mounting it like Tina, but concluded that there was too much restriction blowing against the back of the wide louvers, and I generally do things the hard way anyway ;-). The way mine is mounted, the cool air comes up from in front of the inner wheel tub, which would work great as is, but eventually I want to build some side inlets anyway, just for looks. they will be much like the ones on Madcurls silver chop top. simple but distinctive.
BTW: engine overheating isn't an issue here, except for the melted plastic wire looms, and fried alternators etc, that die from heat stroke . the car runs 180 even on 100 degree days.

Ditto
The reason I installed mine is airflow ...
sitting at idle for long times with short spurts at high rpm's tends to heat things up after a while.
Fan cured that problem.

this is a 10" opening? looks smaller. i've been wondering how big an opening could be cut there. it would make my irm rocker scoops much more practical.

i just recently finished wiring up 2-10" fans under the side vents. this was for a 4cyl though, more or less playing with a solution to a different problem, (check "convertible comfort" in the tech archives). i found that they're not needed but finished wiring them up in case i want them later (say if i change to a larger engine).

ceramic coating the entire exhaust system will also help reduce under hood temps as well.

Tina,Is the fan to blow in or out?From the shape of the blade,it should be blowing in.

The vent mounted on my engine vent grill is wired to vent(blow) hot air out.
Since this thing is so easily reversable I tried both.
Pulling the hot air out drops engine bay temps a lot quicker than trying to introduce cold air to drop temps.
BTW Due to the angle of the vents the air flow is almost horizontal, but not quite.
Which is a good thing, last thing I want is "small scratchy particles" blowing right past the new paint on the decklid.

Not an issue. You're just removing light guage sheetmetal. There's already a couple of factory placed holes in that area, so you can feel around behind the wall and tell how much you can cut out without hitting structure. The front 1/4 of the opening will be blocked by a heavy structure piece, so don't cut that .

Tina,If you have the fan blowing out the vent the blade is facing the wrong way to be as efficient as it can be.If it is reverseable(the blade)you will mave alot more air if you turn the blade over.
Picture your hand cupped when you are swimming.If you cup the water you move a lot more of it than if you turned your hand over and tried to swim.

Got it
(In my best saturday night show voice)
You Sir, ARE correct.
The way you decribed would move more air.
I was pondering the thought a while back too.
Thing is, the only way due to the way the fan is mounted on its own little housing,, is to flip the whole thing over on the grill.
Opted against that though, cause those 2 small brackets you see the fan bolted on to was just what I needed to push and hold my cooling tubes out of harms way.

i get a little noise and can feel a bit of vibration, or at least i can feel that they're on. but mine are on a convertible so it may not be as much of an issue on a hard top. also you have yours going further down in the engine compartment so that may help you too (and do you have fans on both sides planned? guess that would be an issue too).

mine are not quite hard mounted. i used some threaded pieces that look something like a cross bettween a washer and a spacer made of rubber with a nut in the end of the spacer looking part. you drill a hole for it and it expands in the hole as you tighten it down. wish i could do a pic. if you get desperate for something like it i can go by a hardware store and get a proper name for it. however, because of the scoops i put over my fans, i couldn't get them in all 4 positions so it's mounted harder at two points. if next summer, when the fans are on more often, it bothers me enough i'll try to get the rubber mounts in the other spots.

also as you know the side vents just slide into position at their front edge, so that might give them a bit of vibration freedom. it's not like i hear them rattling though, just something to think about. i'm also just remembering that i only have one finger screw holding them on from when i was building and experimenting with them so bolting the other side down might help too.

like i said earlier, i haven't had it wired up for very long so it could be tweeked more (i'm not compleatly happy with the thermostat controling it), and with your position for it and being a hardtop also this may all be moot, but that's my bit of experience with it for now.

Yup. I know what you're talking about. like used on the Fiero luggage rack. That's a great idea actually. I own a saw shop in my real life, so I have lots of little rubber mounts to chose from, but haven't picked one out yet. I'll post a photo, with fan installed, next weekend in chapter II .
Thanks for the feedback on the noise issue, As I was concerned about that. these small fans really zing, and do make lots of wind noise wile testing on the bench.

Thanks,

That shroud is right where the plumbing for my elec water pump is located.

I'm sorry........ I didn't notice your plumbing while I was cutting out the hole
