Hello all been awhile since I have been around but I am back in the Charger world. I got an 07 SubLime Daytona. It came with the Mopar CAI and nothing else. I am gonna put the 93 CAI performance tune on from a Diablo tuner. Do I need to put a colder thermostat in it or can I just put the tune on and be ok with out killing cooling fans or anything else?

Thanks

The stock fan settings for the Charger are 217 deg (Low speed engage) and 226 (High speed engage) with a 203 deg T-stat. The Predator performance tunes tighten up the fan settings to 210 (Low) and 219 (High) so you can still get a slightly cooler upper limit without doing anything but adding the tune.

I agree with rodneyiii here! Since the tune will increase heat with extra fuel and timing, it is advisable to turn on the fans sooner. Another thing to do is add some ACES IV to the gasoline. This will utilize more of the fuel as power/work and leave lubricity to cool the cylinders down much more. Results in 6 times less ring and bore wear and 4 times less stem/guide wear!:beerchug:

No stat is necessary or really advisable.

So The fans are good with the tune lowering the temp for them to come on or should I lower them with the tuner more? And if so what temps should I do?

Actually the 210 and 219 is good. Remember that cooling is accomplished with 3 distinct functions in the engine.

1) Engine coolant
2) Engine Oil
3) Radiant Heat loss.

Once you have the tune and the fans are at the 210 and 219, then ACES IV will help with the reduction of heat due to better combustion of the fuel in the tune with less friction in piston rings, stems and guides.

QuantumBlue HP Gold Coolant we manufacture reduces heat faster because it doesn't have any sodium or sulfates that hold heat. 3 to 4 times faster evaporation!

We could make you a QuantumBlue HP Custom Blend that evaporates heat and yet maintains integrity for 10,000 + miles at the same time. Remember that 30% of your heat in the engine is taken away by our oil! Most people don't realize this!

We can't help on the radiant heat portion however.

These simple pour in mods will greatly assist in heat reduction, increased performance, more power and cooler running.:rocker:
