i was wondering since i used to have a ls1 ta, i installed a 160 thermostat in it and a programmer and it helped it. I already have my edge on my f150 and i was wondering if a cooler thermostat would help my truck also, i know in this texas heat all the time it can get hott on the egt and cht. would a 160 thermostat help my truck? if not would a cooler one? also what degree are our stock thermostats?

 

Not sure about your model year but the 5.4 3vs come with a 195 and need at least that. The guys doing tuning have said that these engines are most efficient at about 205. If it were me, I would leave it alone.

 

thats warm..... always thought cooler more power... i really need electric fans bad, exhaust and change from these 3.55 open diff very badly..

 

what do you mean by help your truck? get it going better? run better/more efficient?

typically the cooler a vehicle runs the more power you can get out of it. if you start getting into tuning, maximum efficiencies, and all that these trucks just can't handle a thermostat too much cooler.

i've always wondered, what if i put a 205* tstat in knowing it will probably open around 195-200? will this help the truck run better?

 

Definitely do not need a 160 thermostat, especially if its N/A. I have a couple guys that I know that have Lightnings and they are running 170 thermostat.

stevenminix, If you have stock pulleys on a N/A engine then a stock 192 thermostat is good. If you have underdrive pulleys then i would suggest getting a 180 thermostat to off set the under driven water pump pulley. Ive got the failsafe thermostat installed in mine.

I agree with BlueJay that these modular engines perform good with decent gas mileage in the 202-210 temp range

Electric fans(DIY or pre-made sets)...Exhaust(choose you your own)....And if upgrading rear end get a Detroit Tru Trac(set it and forget it) wont hurt either...

just my .02 cents

 

thanx forgedf150, u nailed me right on the head, good info.. im just out to get the cheapest electric fan set i can.. exhaust i already know what i got in mind there, and yeah the detroit looks like my fav diff. i been looking for efans though and just think like 550 to 600 bucks is way too much.. like i said anyone got any cheaper ideas.. i thought about trying to piece a kit together but id like to hear what u guys think about most cost effective efans?

 

PM this guy for info on electric fans. He has installed several kits he put together. Knows a lot about them.

some people have been going to their local "You-Pull-It" yards or other junk yards and pulling electric fans from... i believe 96+ V8 Thunderbird... then going and buying a controller..

Here is one that I've seen recommended a lot... Delta Current Control -- Using the, well its been upgraded now but I believe it is the "FK-50P"

You might PM Patman03SprCrw... I think that is the setup he used, but he can confirm or change that...

That should get you somewhere in the price range of $160-$200 total... hope it helps

 

steven look at troyers fans, most of the guy hear run them, and they are only $425.

 

I bought ebay fans and a hayden adjustable controller and it works great.

 

thanx ill check it out
