I just read this on the Spoon website:
" If water temperature exceeds 85 (185F) degrees, Honda engines will loose power abruptly. By making water temperature low, engine power will subsequently be increased. "

My car usually sits at around 180-190 F, right where are thermostats are at. Do you think I should look into a lower thermostat, like the spoon one, which opens at 149 and is fully open at 158?

If what spoon says is true..maybe this is a worth while mod?

 

That really doesn't seem to make a whole lot of sense. Why would honda make the thermostat open where the engine begins to lose power? Plus I don't think it is that simple, saying the engine will loose power abruptly at a certain temp.

Just my .02

 

yeah thats some stupid bullshit.

 

man, if you lose power then my engine must suck at 210 degrees, damn.

motor runs strong though, explain this bs theory.

 

guys dont have to get angry...just quoting it off spoons website..maybe its bs then.

 

ive seen a few stock cars reach really high water temperatures on the
dyno, i guess there is a power loss associated with higher temps,
but nothing like ""If water temperature exceeds 85 (185F) degrees, Honda engines will loose power abruptly""

 

maybe its just me but my car definitely feels more sluggish after its warmed up. FWIW its a stock 96 Civic EX. when i first start the car, it feels more peppy, but after the car warms up, throttle response goes out the door. dont tell me there is no throttle response on a SOHC VTEC because its there when the motor is still warming up.

can i just put in an aftermarket low temp thermostat from say...pep boys? i know im in the wrong forum [my car is NA] but the search function led me here.

 

How is a stock 96 Civic EX peppy?

Im beginning to get bored of my cars power and think its starting to feel sluggish Oh yeah, guess that's why Im rebuilding for lots of hp.

 

when you are use to driving your parents cars or say a slocus, any thing is peppy

 

whatever, im just saying the car feels noticably slower when it reaches normal operating temperature.

 

well its not really bs cause when the cooling temp does raise that means the motors getting hotter. the hotter the motor the less powere its going to produce. that s why when you get a dyno after each run they need to let the car sit so the motor temp lowers. at high temp comes lower hp. if its bs then why does it mater on the dyno. the spoon sports thermostat really work by keeping the motor cooler. the factory one is meant to keep it at normal temp. if you think drag racing or road racing counts as normal driving then the stock works but if not the spoon is meant to lower the car cooler cause its meant for hard driving.

 

Actually it is true. The computer strategy is to pull timing out as coolant temp reaches a predetermined value. This is a function of safety, to make the car less prone to detonation/preignition. While I was dyno tuning a GSR, I could look at the scan tool and see as the temps hit around 200F ish, the car would not reach total timing advance. This directly correlated with a drop (signifigant) in power on the dyno. Yep, it is true.

 

for lightning and W.ZeroB18C1T

 

to add to this, optimum power is made when water temps are around 160-175 degrees.

 

This is some weak *** bullshit. Its old school technology...a hot motor with cold gas is where its at. You want the motor to be hot, but have the air intake temp and gas to be cool. I know plenty of guys, in full race cars that wont even turn the dyno on until they make 4 or 5 passes because the motors not hot yet. I dont even turn my race car off once to let it cool down. As long as the air temp is cool and the motor is not totaly running hot (well over 180) then your good to go. If anyone has any. Just because a thermostat opens earlier, doesnt mean its not going to get to the same temp. Its all in the flow of it...hince thats why some people drill them out bigger. Most of what I am saying is on full blown race cars as I realise a lot of you cant do the stuff we can on a race car on the street to acheive this. I have also seen when cars are to cold they mis....esp turbo cars.......Mike
