Red Hot Turbos

Rode hard, put away wet

I mean....I’m surprised someone hasn’t asked this, but how hard were you running it?
Like 100+ mph. Just curious cause I know we all have spirited runs in our raptors.

Was running back home the other night from Pulmo area south of Los Barriles back to Cabo and pulled over to grab some food. Anyways when I got out I noticed the Turbos were glowing red hot. I was running the truck hard but not any harder then I normally do down here. Wondering if anyone else has noticed this? Truck was running perfect and running perfect after I ate.

Since you are in a pretty warm climate have you looked into adding a coolant additive that helps dissipate the heat better. I know I did this on my white Raptor and it made a little difference. not a huge effect but noticeable. Also changed out my coolant tank since my stock one started to show signs of breakdown due to the higher temps.

Wetter water is amazing. I know a lot of Ferrari and Lamborghini guys use it.

That is where the idea came from. We use it in our race cars, our crew chief is the one that suggested I run it in my truck. Great product, decreased my coolant temps by about 15-20 deg. in the hotter months.

Does anyone remember when the Nissan's used to cook oil in the turbo's really, really bad? Then they put an electric pump on them to keep running oil after the car was shut off, then they had trouble with the pumps running so long the batteries went dead? What a cluster that used to be. These modern designs are SO much better.

Are you running a colder t-stat? I swapped mine for a 170 degree and I rarely see my temps go above 190-195 even on the hottest 100+ degree days in Texas.

I did that after I already treated my coolant. South and West Texas summers were killing my coolant. Even with the treated coolant and the 170 T-stat I still ran about 180-190 in the summer.

Either of you guys have the fans programed to come on at the lower temps, or just swapped out the mechanical Tstat and called it done?

Excellent question.

Attached is the stock cooling fan table based on engine coolant and ambient air temps. The stock coolant target temp is 210 degF, so the cooling fans really don't get going until the coolant temp is 220 degF.

The Grill shutter tables are terrible as well if you don't have an aftermarket tune. I personally don't know what values the business tuners set these to because I set my own values. The Cobb OTS maps reflect all stock values for the cooling fans, but the IC shutters are set to 100% open in the Stage 2 maps.
