SC intercooler fluid temp range?

[cougar9150]

Just wondering what the intercooler coolant temp range was for a Trilogy or Eaton SCd cars. I'm looking into making a flow switch setup for a buddy of mines car (Dave w/the Trilogy-the other MM owner in NPR) and need to know the upper temp range to properly spec a flow switch.

Just looking at a switch to activate a LED when there is/isn't flow from the IC pump. I have also looked at a couple that register temp, flow rate, etc... but those can get expensive.

Usually 30-40 degrees above ambient.

[Loco1234]

wow 30-40 really... I kinda always thought it was 20 or 25+ degrees but 30-40...

i run a Vortec JT-trim & a custom froozen boost setup w/ two 10" pusher fans...
I find 10-11 degree increase while at highway speeds & RPM...

Thats the difference between a massive heat pump and a small heat pump.....combined with said heat pump/intercooler physically bolted to the 200 degree engine.

mine was getting up there on Saturday, my IATs were reading 145 at their peak. ambient couldnt ove been more then 80*

Not GOOD. :(

Hmmmmm. Very interesting. Keep us posted.
Please.

What type of set up do you have for your heat exchanger, and where is it mounted?

[Zack]

On a 90 degree day with the air on, An eaton/Trilogy is completely USELESS

This is the only saving grace to an Air/Air Kit...never more than 10-12 above ambient.

I was so pissed off yesterday when driving the car I damn near parked it and removed all the blower stuff.

Uh-oh, don't know if I like the sound of that. If you're not happy about it, not a good thing.

Its fine if you drive normal.

Got it. Was concerned that you were referring to overall driveability. :sweat:

Those high temps can really through off a tune that is setup with very close tolerances... such as if u dyno tuned it in the winter & now driving it in the summer with High air temps...

[Marauderman]

I have the led light to tell me the inter-cooler pump is working and have verified it in the pass---as to the temps.....my gauge never seems to go above 120 no matter what ----and BTW....I have replaced my inter-cooler with an additive of wet-water---about a 65-70% water to 30% ww..has worked well in keeping the temps down in very hot weather.......

Ya, I use Royal Purple water wetter too. The royal purple one is nice because the purple additive glows in UV light so it is easier to find leaks in the system. fyi

Any good Base SCT SC tune will yank 6 degrees of timing at 140 IAT..totally safe.

[Zack]

When I get time, Im gonna swap a 170 stat in the car, Add Water Wetter to the IC circuit, Block off the air filter from engine air and possibly add another heat exchanger between the IC and reservior.

Im getting sick of all this, honestly.

That's a great idea---I will try that brand next time--would not have known that--thanks for the tip---gotta love this site....

KILLER CHILLER.

Come on Zack, I'm pretty sure you could hook it up in a couple hours.

lol he called me up yesterday all pissed and mentioned one of these.

The royal purple one is nice because the purple additive glows in UV light so it is easier to find leaks in the system. fyiIs RP water wetter compatible with antifreeze? I don't drive The Blackbird a lot in the winter, but I don't want to have to drain the whole system every season, either.

*EDIT* - Nevermind, I just answered my own question.

From the RP web site:

"Purple Ice should always be used in conjunction with antifreeze in regions where freezing temperatures occur. Purple Ice is recommended for any water / glycol pressurized cooling system, including those using the traditional green silicate based glycols or the newer OAT or HOAT based glycols."

Now I just need to find some....

[FordNut]

NO. It says so right on the label. The Redline water wetter is claimed to be compatible on the label, but some people on the forums claim to have problems with it. I've always used it and never had a problem.

[RF Overlord]

OK, now I'm confused...the label on the bottle says NO, but their website says YES...

I'm-a send them an e-mail....

Maybe they have changed their formula, it's been several years since I checked. That's why I chose Redline.

[RF Overlord]

I sent them an email and I'll post it here when (if) they reply.

Agree 100%. My car SUCKS right now! It's great for helping out pushing the car under normal load with the air on, but forget all about performance! Weak sauce...:mad2:

mine really dosent seem that much weaker in the heat? maybe cuz my car is already weak? lol

[RF Overlord]

We just came back from a mini-meet in New Hampshire where it was in the mid-high 80s and I didn't notice any difference in performance, even on a couple of laps around NH Motor Speedway at 90+ MPH (with the Bunny-lady driving :eek: ).

I will admit that we had Lidio keep the tune conservative as The Blackbird was our only car at the time and I wanted it ultra-safe, so maybe it doesn't make as big a difference.

[Dennis Reinhart]

This is why I like Vortech on the Marauder, it does not become heat soaked as easy as the Roots type super charger, now if you are running a Roots the only thing you can do, to keep heat soak down is increase the reservoir add a higher volume watter pump for the heat exchange, put the huge Cobra cooler on it with triple fans on it. And run 50/50 AF and watter and use watter wetter or some thing similar, this is my opinion I respect yours.

[justbob]

This morning it was 73* and the car felt like a rocket ship! Mid 80's now and definately weaker but WAY better than the other day where I was stuck in traffic for 4 HOURS. I really wish I could have know my IATS that day. They won't go above 120 sitting or 116 moving for the little 25 minute drive I took with no traffic. Car felt pretty good and tolerable but not as good as this morning. Also NO slippage taking off, It only will do this feathering the gas when in the mid-high 90's with air on.

[Marauderman]

This is why I like Vortech on the Marauder, it does not become heat soaked as easy .............

This is why I like the one I got from you---what --7 years ago---one of the first 7 I believe water to air------

My MM since has never starved for power from heat so far.........

[justbob]

Sorry, I've read about too many issues with centri's in 15* and under temps. Here in the big windy it is not uncommon to dip into the negatives. The vortec was damn near in hands before I backed out because of that, along with the good price I paid for the Trilogy, there was no way that I was gonna take that chance seeing as though my car gets daily driven or is at minimal a third car on stand by incase another were to break.

[LANDY]

mine on traffic in Miami the most i saw was 132* at 96* outside temp, and today i decided to take the car to work becuse it asked me to drive it, i was cruising at 80mph and it kept itself around the high 90's and it was 88* outside.
i love my air to air.
no disrespect to the trilogy/eaton guys, you guys are kings of torque.

[RF Overlord]

Here's what RP has to say:

Purple Ice will mix and is compatible with this antifreeze coolant.

In a 50/50 mix of coolant to water - we recommend adding one ounce of the Purple Ice per quart of cooling system capacity.

Thanks for choosing to use RP.

Wow this thread went in another direction rather quickly.

Can anyone tell me what the stated flow rate on a standard Trilogy/Eaton IC pump is? I think read somewhere that the OE Cobra pump flows 317gph/5.28gpm but wanted to make sure before I ordered a switch.

I am probably going to spec a SPST switch that will close the N/O contact at a flow of approx 3-5 GPM depending on actual IC pump flow and the cost of the unit (need a brass or SS body probably to withstand the engine bay heat). This will then power a relay that will light up an LED showing that there is flow in the IC cooling circuit not just that the pump is on/drawing power.
