anyone try this stuff?

my friend put it in his SRT-8 and it seems to run about 10* colder

anyone else try it

ive used redline water wetter before in my GTP and i saw a slight drop in temps.....i dont see why ud need it for the civic tho

 

[Ron Vogel]

snake oil....

Downy works better as an additive actually!

 

[Mook]

i thought the same but the water wetter did drop it like 3 or so degrees after that i just decided to run a 160tstat

.....i dont see why ud need it for the civic tho

friend told me to try 2 runs without it
and then try 2 runs with it

he said it might make a diffrence

 

[Mook]

difference in what tho?

 

[DanJ]

HP, Duh.

 

[EmersonHart13]

TQ!

I think additives are something to stay away from in general. Fuel additives, oil additives, etc. If it works that good then why doesnt it come in the car from the factory?

 

[Stink Star]

all that stuff does is drop the surface tension of the liquid... so it actually not only cools off daster but warms up faster too.... but anyways, id stay away from that! do what i did on my 07 SI and bypass the water line through the throttle body.... you will see a bigger improvement with that, than the coolant additive

SRT8's run hot stock (usually a little past the center)

BECAUSE ITS A RACE CAR! DUH!

That stuff isn't meant to add to coolant, it's for people who run straight water in their cooling systems but want to keep a lubricant additive to not destroy the bearings in the water pump as well as prevent corrosion. (coolant has lubricants in it already). So, naturally you're going to run cooler using just water as water has a greater natural ability to dissipate heat than does coolant/antifreeze.

Why don't they use this from the factory? Because your block would freeze in the winter time and you'd be SOL with a pile of scrap under your hood.

used to CREEEP up to 200*

now it stays at 180*


redline that is..

tell me a little more about that

It's pretty simple/straight forward. Just undo the coolant hoses that go to and from your throttle body (probably directly underneath the inlet) and clamp a tube inline with them or get a new piece of hose and run it to/from where each of the original hoses start from.

This will decrease intake air temps, but it's also going to make your car run like shit for the first 20-30 minutes of driving when it gets cold outside and you may lose a bit of mpg due to the cooler, more dense air charge requiring more fuel.

You also may notice a high idle for longer than normal on cold starts depending on how the IAC works on those motors. I know mitsu's use coolant through the TB to determine IAC motor position. I don't think Honda's are the same, but you may want to look into that.

thats how you do it... but to be honest i havent noticed any problems with cold sarts in the winter, maybe its brcause our civics are drive by wire? but i have noticed a big improvement in reducing heat soak after driving for awhile... apparently K20's love cold intake temps- even hondata sells a phenolic intake gasket that reduce heat transfer into the manifold, and they are a very respectible company.
