http://www.preludeonline.com/showthread.php?s=&threadid=50452&highlight=mugen+thermastat

There is no point in doing this mod unless u get the low temp switch by mugen too (www.kingmotorsports.com/products/mugen/prelude/engine.html)

And all in all it cost about $65 or so for both the thermastat and temp switch. I highly recommend getting the and the hondata "heat shield"

So far i have not done this mod yet but will soon. I highly suggest u look at those links i gave u

anyone got it? u like? and performance diff?
performance gains? you wont get any at all.. its like saying mugen valve cover.. you wont get anything from it..

yup a big waste of money.. i recently saw a mugen "high performance" as they put it, radiator cap.. sheesh

This thermostat has the operating temperature set lower than normal. It prevents engine power loss by minimizing rapid water-temperature rises under harsh conditions such as during circuit driving. The use of a flow-control-type valve prevents hunting, thereby achieving rapid stabilization of the water temperature (the engine warms up within a short period).

Operating temperature: 68°C (STD.: 76~80°C)

Full-throttle acceleration temperature: 83°C (STD.: 90°C)




Activates cooling fan at 80°C instead of the stock 93°C. Requires use of Mugen low-temp thermostat.

looks like all it does is work to lower the engine temp, as well as heat it up faster. it might be worth it, depending on certain factors. but oh well...

lower engine temps = lower intake temp... we al know that lower intake temps = more power...

unless you live in cold climate, i dont see how the t-stat and the fan switch will keep the engine significantly cooler, to the point where anybody could tell a difference...

the mugen t-stat may open sooner than a stock t-stat, but once they are both open, they will behave the same... in other words, a motor that has a coolant temp of 190 degrees and a stock t-stat will cool off just as quick as the motor that has a coolant temp of 190 degrees and has a mugen t-stat... it makes no difference if the t-stat opens up a few degrees earlier...

as far as the fan switch goes, i believe the money would better spent somewhere else... the fan's purpose is to draw air through the radiator when the vehicle is not moving fast enough to provide enough air circulation... they only turn on when the car is in idle, low speeds, and at times, when the car is off... during racing conditions, the fans do not turn on, as they are speed sensitive... look at it this way, if you were going down the dragstrip, would you want your fans to turn on in the middle of your run???

so imo, take your 65 dollars and spend it on something worthwhile...

If u read the post i posted earlier it isn't:rolleyes: It would be pointless if u just got the thermastat but u would c good gains w/ the hondata heat shield, and mugen thermastat switch. I highly recommend that u read the post before u say there is no gains:eek:

Despite what you typed, a lower temp thermostat does change the temp in which the engine runs. The fans and the thermostat are what regulate the engine temp. If your cooling system is in good condition then your car should run cooler. As far as performance gains I am not sure but I'd say it is definitly a worthwhile investment in that it would be beneficial to the engine. Definitly look into this if you are turboed because engine temp is a main concern.
Honestly I doubt you will "feel" anything as far as power wise but I am spending my money on it. Sometimes the little hp things add up.

yes lower engine temps means more power cuase of the lower intake temp.. but see the thing is, is just because it opens up earlier doesnt mean it keeps your engine cooler overall.. it just keeps it cooler in the beginning but will eventually get just as hot as it normally would

how does the t-stat change the temperature in which the engine runs? how is a t-stat and a fan switch going to help your engine cool once your coolant reaches 200 degrees??? if i driving down the dragstrip how is the switch and the thermostat going to help? if im wrong explain...

it sounds like you are just regurgitating what people are saying on other boards... it "should run cooler", but will it???

as far as the hondata spacer goes, i can see how it can help... by keeping hot coolant away from the tb (i dont know how you 5th genners are going to do it without tripping a code), and by insulating some of the heat radiated by the engine away from the intake manifold, intake temps will be cooler...

for once, i agree with what you are saying... ;)

With a lower thermostat and fan switch then your engine SHOULDN"T reach the say 200*F or whatever.

No I am not regurgitating what other people have said I am talking from personal experience on other vehicles with changing out the thermostat and such.

Why would they sell all those different thermostat temps on chevy 350's and such if they don't matter? Why would say Jet Performance Products say to put in a lower temp thermostat with some of the computer chips they sell? I am NOT saying that you are gonna get like 50hp or anything from a thermostat. I seriously doubt you will be able to even feel a difference. I am saying that your engine should run a little cooler, which is a good thing IMO.

For the coolant flow into the throttle body, you can just bypass the coolant hoses going into the throttle body.

i can see why you believe what you believe, but you have not answered any of the questions i previously posted... all you are saying is "should, should, should..."

all im saying is that all t-stats behave the same once coolant reaches a certain temperature... fans do not turn on once the car is moving any faster than 20 mph, and if they did, it wouldnt do the car any good...

its your money i guess...

the point of a lower thermostat is that it keeps your coolant from reaching those higher temperatures. Obviously both thermostats are gonna work the same if the coolant temperatures are high enough to have both fully open.

theysay its 20 degrees cooler even after racing for a while
and they say placing the "tornado" in your intake will give you 20 hp... :rolleyes:

here's a direct quote from a book i dug up, its one of many you would have to go through to get an ase certification...

--------------------------
automotive service: inspection, maintenance, and repair
tim gilles
delmar publishers, 1999

chapter 20, cooling system theory, pg 257

...no matter how hot the coolant is, a properly operating thermostat remains closed until its predetermined opening point. a common misconception is that installing a lower temperature rating thermostat will result in a cooler running engine. this practice will simply result in the engine operating temperature being lower during cooler weather...
---------------------------

enjoy your mugen t-stat and fan switch... while you're at it, dont forget that radiator cap...
