CENTRI GUYS? what electric fans are you running?

I have had and have both setups and air flow using the Mustang shroud or the inverted stock setup the condition you've stated has never happened. I don't know of any location that is hotter than it get here in south Florida, so unless the MM is in Cuba , Mexico, or the SUN the stock fan or Mustang setup would be OK!

WRONG! IT has happened to several. Probably many more they just don't know it because they do not have a scan guage.

Thanks for all the replies . I'll try to give some more info on what was happening then and now .
First , the RPM's at 70 are approx. 2150 . I still have the factory 3:25's in the rear .
Dennis installed the Novi 1500 , 3000 stall convertor , etc. .
Remember the car just came back from Florida ( Dennis Reinhart's shop that did the install ) . He checked out the program and dyno'd it , said everything was fine , does not know why the poor gas mileage , or how to remedy it) .

I also just got the car back from Bruce Tucker at JBA Performance in San Diego . He is a guru with supercharged motors ( Mustangs , Marauders , etc. ) . By the way , a AWESOME person to work with wth supercharged motors. He data logged the car for quite a long time , and suggested the aluminum radiator which I bought from Dennis Reinhart . The overheating problem we believe was lack of air flow . On a 105 degree day with only 5 percent humidity out here in Nevada , if the car sat at idle , in gear , A/C on , for any more than 15 minutes , it got up to 260 to 270 degrees . At that point , if you took the car on the road and did over 25 MPH , the temp would come right down to 210 .
Now with the aluminum radiator , it "seems" to have corrected the overheating . Car runs about 190 on the interstate , and when it was 108 in air temp out here , car in traffic was at about 215 . That would be about normal for this climate in the hot summer .
Gas mileage has not changed since I got it back from Dennis's shop . City t highway only lends me another 2 or 3 miles to the gallon . Tops out at 11 or 12 at best on the highway at a steady 65 to 70 MPH .
Excatly what the specs are on all items installed along with the SC , Dennis would have a spec sheet . He did a great job on the install , car runs out great , not a problem there .
Hope I have not bored too many of you with all the info .

Mike M, thebeeper & sailsmen are just making up stuff. Even Ford made up stuff, that's why they spent all that money on the MM Fan Shroud when the could of just used the Mustang saving a lot of money.

The 1996 Cobras in certain areas also experienced this problem and a TSB was issued to improve air flow over the rad. http://www.svtperformance.com/forums/sn95-cobras-24/384925-1996-cooling-tsb.html

Trader Rating: (1) One of the big indicators that the TSB has been performed is the fan shroud. The honey comb grill was often deleted as well, but I believe it was possible to still leave the honey comb grill on. Every stock/factory original 96 Cobra has the same cooling system. The cooling system is only a real problem for states with hotter climates, such as California, Nevada, Arizona, etc. My temp shoots way up on my Mystic if I drive the car hard on a hot summer afternoon. For others where climates are typically cooler, it's not a big deal. The TSB will replace the a/c condensor to one that has less fins per inch so that more airflow can get to the radiator. The radiator and fan will also get replaced to the newer 97/98 style radiator and fan. The TSB is expensive. It'll cost over 1400 dollars to have it done. I'm considering getting all the parts and doing it myself.

I have the mustang fan on my DR Novi NOIC setup in Orlando and get 13-14 MPG city and low 20's highway. So I don't think I'm overheating.
 
What Sailsmen is saying is 100% correct in super hot temps the Mustang Fan which was the setup used on the Vortech kits quite a few had overheat problems due to this. I can speak from 1st hand experience on this.
 
I have the mustang fan with 170* tstat and fan fan setting 185* then 200* if I remember correctly.
I have only seen the temps at 220 * when i was in heavy traffic with A/C in the middle of the city with outside around 100*.

Similar to when I had noticed the problem on my 03 w/ Vortech almost stand still traffic-10mph tops speed & 100 plus outside.
 
Im leaning torwards this setup! becool 11" fans 2800 cfm puller

Tried to put the factory air dam under car but no go with my intercooler mouth.

One of my guys also just installed 2 air dams on either side of the IC mouth but even without this it seems temps are well in spec now.


Ambient temps have been about 115 out here but now cooled down to about 105, where is my jacket?

Do you have your intercooler in the "stock" FIT position?

HighwayCruiser tucked up the intercooler on my FIT Maruader and the factory air dam fits:

I too have the OEM fan flipped 180 degrees and have not had any overheating issues here in the hot, humid, and steamy Ohio Valley.
 
I found this on yellowbullet.com and thought it might be of some use in this thread....

Well i had some fun yesterday

I needed some toys at my local pro hardware store, and there was a demo all day long of a company selling paint booths aerators, the guy was showing off their new fan designs and comparing them to the competition with some meters and other gizmos, anyhow, he had a box where he would put the fan cases and it would calculate the cfm produced by each fans that was attached to the air box

guess what i did ? ;-)

I brought all the rad fans i had in my possession

LS1 kit
LT1 Kit
A 1999 Dodge stratus Kit
1996 Ford Taurus Fan

Well the guy looked at me funny, but he agreed, after a 50$ in his pocket. but you know what...i just wanted to put my mind to rest so here are the numbers

First off they were ALL tested at Battery voltage (12.5v)
first and then with my truck running with a 30ft 4 gauge wire from my battery 14.5v

Not the exact numbers they fluctuate from 150 to 250 cfm this is an average

Battery operated

LS1 FAN SHROUD
1 fan turned on - 4800 cfm
2 fans on - 9500cfm

LT1 FAN SHROUD
1 fan turned on - 5000 cfm
2 fans on - 8700 cfm

Dodge Fan (both fans are always on - 2 speed)
Slow speed - 3700 cfm
High Speed 9000 cfm

Ford Taurus (1 fan two speed)
Slow speed - 2800 CFM
High speed - 5600 CFM



Alternator Powered

LS1 FAN SHROUD
1 fan turned on - 5100 cfm
2 fans on - 10500cfm

LT1 FAN SHROUD
1 fan turned on - 5200 cfm
2 fans on - 9500 cfm

Dodge Fan (both fans are always on - 2 speed)
Slow speed - 4200 cfm
High Speed 10400 cfm

Ford Taurus (1 fan two speed)
Slow speed - 3200 CFM
High speed - 6000 CFM



So keep in mind not all fan are made the same, you can have different numbers if you have a motor that is more used than the other

so the conclusion here is that ls1/lt1 fans produce around 10000 cfm when both motors are on

they pull the same numbers compared to the stock fan that produce 10000 cfm at 3000rpm from what i have read


So I must wonder now

i did not have a clutch fan to test out the cfm of it operating, but i do see the numbers he posted earlier, and the electric fans are about the same to his...

BTW the way the guy selling the booth fans was not nuch impressed...

his electric fans 13.5" diameter (operating on 120v) actually pushed out 17000 cfms... and could slice a celery , his way fo showing that the blades were slicing air or something...the ls1/lt1 fans were not able to slice a celery but mostly just crush it or just stop the blades....lol

Mine is in the stock location.
When you move it up like that, do you think you are covering the radiator and maybe effecting it's efficiency?
 
Keep in mind the idiot guage does not move until the 230-240* mark, too high for an s/c.

Unless you have a scan guage you could be running hot and never know it.

I am just starting to look into low profile fans and came across this old thread/post. Sounds like a Mustang fan would be a low budget option, but not as reliable in hot weather. A twin fan like the one quoted above seems to be the way to go. Any better suggestions out there?

Thanks!
 
Made my own shroud.

Used 2 12" mishimoto race fans with the stock controller. This setup has not been fully tested by me. I gave a fellow in Bahrain the info and he said it's working great for him.....
 
I forgot about this thread! I have since upgraded to a Aluminum Dubz radiator, and Spal Exteme 12" dual fans pushing over 4K cfm with a 170* thermostat , staying nice and cool so far.
