Nismo Thermostat For Drift?

[FAST-GT-R]

OK!

Now, for the pro's.

I have a RB26 powerd R32 GTS4, its setup for drift with my dancer grid controller ( rwd etc) works a treat.

car is setup for some dori. I was thinking> I have a thick arc cooler the car now never overheats.... seeing never past 85C in temps even if i sit on rev limiter pretty hard with my hks metal headgasket i got here also.

since the nismo thermostat opens up about 12C earlier, will that mean my temps will be floating in the mid70's? is this bad as the stock one opens up about 72C meaning its just going to run very cool? what will the side efects be of running lower temps...

cheers

Out of interest how much was your nismo thermosat?

[FAST-GT-R]

i paid 75$

it wont make bugger all difference. also a thick intercooler will often make your engine (water temp/oil temp) run hotter, not cooler. A really thick core pre-heats the air before it passes through the rad. if you want to control engine temp you need a nice big oil cooler properly mounted in a duct.

cooler? :lol: im talking radiator here, i dont have a front mount

also got oil cooler with no thermostat

i just want to know the best operating temps for my car... to make the engine live aslong as possible.

i heard, just because the thermostat opens up early, doesnt mean temps will drop uptop, will get to the same heat

what they do is extend the time engine oil get into working temp, hence more engine wear

bigger radiator is what u really need if u want better cooling

Begs the question, what oil temp is ideal?

[Nebuchernezzer]

You need oil and water temp gauges to know these answers.

I wouldn't be game to run an engine oil cooler in a road car with no thermostat either.

Minimum gauges for drift IMHO are: oil pressure, oil temp, water temp, boost.

Not the stock water temp gauge either, it reads in a very rough range.

Its interesting to read why a thrmostat on a road car is essential...the way i see it in a road car you are often stationary, in which case oil cooler isnt working, and at best the speeds you travel on the street combined with the fact that you cant really give your car stick on the street so that to the temp differential between your oil temp and ambient air increases, well i dont see it as being that big a no no.

Also, is 80deg C oil any better or worse for your car then 75 or 85 deg C???

I suspect all the Nismo thermostat does is reduce the rate of heating of coolant rather then influence the peak temp, i doubt it will do any damage to an engine...but im happy to hear from soemone htat knows as opposed to guessing

Standard Thermostat is

Commence Open 76.5degC

Full Open 90degC

What is the full specs on the Nismo item, any idea?

Yeah, my question as well re Nismo thermostat. From the way my motor behaves with the stock thermo, the specs you mention above are spot on. I have Microtech so water and air inlet temps on display.

My motor does tend to spike in water temp too fast for my liking so if Nismo thermo helps then all the better. I have Nismo water pump and that also helped alot.

An interesting topic this one , I get the idea that good synthetic oils are less viscous at lower temperatures than mineral oils so oil drag is less of a problem .

There is one school of thought that says lower coolant temps can make more power because less chamber heat is conducted into the fuel/air mix before it is ignited by the spark . So if the detonation threshold is lower a little more full load advance can be used all else being equal .

It probably a case of std thermostat for road and lower for race , its hard to imagine the oil being too cool in a hard worked engine on the track .

In other motorsports (read motorbikes) they dont run thermostats at all. This is because they are revving the snot out of thier motors all the time, and dont have to worry about cruising temps.

Well in one of my old RB powered cars, when i purchased it, it would never go above the cold mark, used lots of fuel and generally ran average.

When i removed the thermostat it was an aftermarket job, that due to the poor designed actually got stuck open.

Even in traffic it would never really go above cold.

I don't advise no thermostat at all it will cause major wear and tear.

The other thing is as well, no thermostat generally means that the water can pass through the radiator too quickly and it can't remove the heat as it doesn't have time and it can overheat at the other end of the scale.

Too Cold or Too Hot.

Thermostat is a critical piece of the puzzle for sure....

My GTR has 1 of these Nismo thermo thingies.... i've driven 300km in it this afternoon; ambient temp = 26-31c, Intake Air Temp = 48-52c, Water Temp = 76-80c and those temps ranged from 110km/h highway driving to start stop start stop with it copping a hiding inbetween

I'll see tomorrow if I have any manuals with it etc.
