Summers here --today will be the first 100 day ---Im running the Vortech and seeing a push on the 3/4 mark on my gage in traffic and higher if stopped. I got the Greddy Rad Cover, Ordered an oversize finned oil pan, Running lite antifreeze and Purple Ice---Thinking bout str8 distilled and a couple bots of water wetter only .... Any Input?? Cap ? Therm ? Whats the Best Water Wetter? Prefer not to go radiater route as yet. $$$$$ !!!!! Fixin to get water and oil temp Gages. Hot motors with no margin for error make me nervous !!!

Well --I tossed the stat,Flushed the system,added bout half Gal of antifreeze,a bottle of Purple Ice and distilled water. Its still pushing one half plus when Im driving in town and Im sure more if I get into rush hour.If Im wide open hyway its slightly over 1/4.---Input ????

 

i have always used redline water wetter with no problems.btw dont use a couple bottles,1 is all you should use.

 

i'm not convinced the radiator cover is a good idea

at high speeds the opening allows some air to escape and blow over the engine bay

it also makes taking those plastic fasteners off a total pain in the butt and if you gotta get into where the intercooler is, you gotta take it all off

I haven't seen anyone report cooler coolant temps with it

water wetter or the other knock off brands are good

a higher pressure radiator cap is cheap and helps. They're all the same. Don't pay more than $20 for one - like the ARC or nismo ones for instance are way overpriced

 

Sounds like a tstat. Thats what happened to me...

 

Mia --I'll replace it just cuz ---Should I go After Market--????And how do u feel bout the str8 distilled and water Wetter only ( No Anti Freeze )--After Market Cap ?
Sentry ---- Im running a ram air hood--Iso Motordyne and no engine cover and in all due respect Seems to me the Air Diverter Plate does just that --Diverts more air thru the Radiator. Correct me if Im missing something. Now for the sake of discussion---Antifreeze is a great heat sink but also a great heat retainer---Hence ---No Anti F just distilled and WW?????

 

I have had the stock and Nismo one fail on me. I just removed mine all together. But if you have to have one just go stock. Stock is $15 Nismo $150. For a 30 degree difference in valve opening its not worth it.

 

Interesting --Left it out. There again -just for the sake of discussion. Iv found that Higher temp therms tend to cool better and lower temp therms tend to cause more heat. Reasoning ???? ---- A higher temp therm (like 195) allows the coolent more time in the radiator where as a lower (like 160) allows for less coolent time in the radiator. And no therm allows no time to let the radiator do its job. Im just throwin ideas around here and covering all aspects. Nothings engraved in stone --Just food for thought. Its going to 2b a hot MF here this summer!!!

 

I heard all this theory before. I pulled mine completely one year ago this July. Since pulling it my standard operating temps went DOWN 15 degrees F to 180-185. (195-200 with the t stat). My on boost hard driving temps are 190-195. My track day temps are 195-205 never going above 205.

 

yeah when my nismo goes bad, I'm pulling it out. I garage my car and phoenix doesn't get below 35 much ever.

You'd have to let the car warm up a little longer though before driving it though right?

 

An oil cooler would help you out! The first thing that heats up is the oil, so if you can keep that from getting hot, it will help your water coolant temps.

Also - a oil spacer does nothing to keep the engine from getting hotter, it just takes longer!!

 

Yup. To date that has been my only drawback of doing this. It takes about 2-3 minutes longer in the summer and about 5 minutes longer in the winter to warm up the car then before. But at the rate my thermostats were failing, the pain in the @ss it was to swap them with the Turbonetics kit, and the improvement in operating temps it was more then worth the hassle of starting my car in the garage and going back inside for a few.

 

So you guys recommend stock t-stat over nismo low temp t-stat in summer?

 

Mood ---as above u see Im getting the bigger pan Fri --Finned and ur right --Im def going oil cooler --But working on Fabing my own ---Cool Mia ---Im going to do that ---Anytime I can simplify and eliminate headaches Im all for it !!!!!----Now --Any input bout the STR8 distilled and a couple bots Water Wetter instead of antifreeze ???? Maybe add some system lube ?

 

Well Nat ----recommending NO therm at all ---Nismo or otherwise---Less u live in Alaska

 

I've never personally run with no antifreeze at all. I don't think a little will hurt you. I certain put very little into mine. Most of mine was distilled and Watter Wetter.

 

Wow is the Nismo thermo that much of a POS? Are they all failing at some point? I'll have to keep a eye on mine.

Eazzzzzzy u might want to take a look at that new mod Sharif posted, the rear cylinder coolant post. Looks intretesting. Just an idea

 

Im on thermostat #4, 1 of which was Nismo, why don't know. But i had them go and now im getting air in the system. Im gonna switch out to Distilled and water wetter or black ice purple ice whatever its called.

 

Unless you have a damaged thermostat, a larger rad is your only solution. A lower temp thermo has no effect on a car overheating. An oil cooler and or better pan will have no effect either because you are having problems when stopped or in slow traffic. That means there's no air to hit the oil cooler, so it won't help in those situations. A higher pressure cap simply raises the boiling point, its not goint to help temps.

 

I'd like to find a way to mount a fan to an oil cooler for things like hot days or rush hour

 

Do not run straight water. The antifreeze is there to keep the liquid from evaporating. You should run no less than 80/20 for a street car.
