I had cars leak coolant before and the oem sensor saved my butt a few times, thats why I have to ask. BTW loving that you guys fighting for our dollars with these awesome sales!! Keep up these sales!!
Answer time!
Fluid levels can be checked by opening the res lid, correct. Correct about the engine coolant point, as well. If by some far out, crazy chance the ColdFront™ System lost all of its coolant the factory safeties would step in. The car will see elevated IATs and start to pull boost and timing and start dumping fuel to keep the motor safe.
In another scenario -- if you went with the heat exchanger alone (remember all of the components are available à la carte) the stock coolant level sensor would remain vigilant over the supercharger cooling loop.
Side note sparked from your great question, and I recall noticing some individuals expressing concern in other areas regarding the divorce in the system -- and I'd like to mention that a divorce has a significant, positive impact on the cooling.
We found the engine and supercharger were fighting over coolant, so a divorce was granted at the factory coolant reservoir.
The CNC machined 6061 billet aluminum ColdFront™ Coolant Reservoir is plumbed directly into the heat exchanger coolant system to increase supercharger coolant levels by 2.175L. Decoupling the supercharger coolant supply and increasing the thermal capacity softens temperature spikes, lowers coolant temperatures, and decreases air intake temperatures.
Some cool data below from our torture testing:
Coolant Temps:
The ColdFront™ Heat Exchanger produced a maximum temperature drop of 13.7°F @ 6960 RPM when ran alone , and 14.5°F @ 7100 RPM when adding the ColdFront™ Reservoir. As a result the system achieved a maximum temperature drop of 24°F when compared to the stock unit.
IATs:
Eight pulls on the dyno - during the eighth pull the intake air temperatures had climbed upward of 180°F at redline on the stock configuration. With the larger ColdFront™ Heat Exchanger in place, a maximum air intake temperature of slightly over 165°F after eight pulls was produced. With the (optional) ColdFront™ Reservoir added, a maximum air intake temperature of just under 165°F after the eighth pull was produced while achieving lower temperatures throughout the first seven pulls as well.
Power Retention:
The stock configuration gave a power loss of 12 WHP @ 6900 RPM by the fourth dyno pull. With the ColdFront™ Heat Exchanger the loss of power was reduced to just 4 WHP @6900 RPM, and with the ColdFront™ Reservoir paired to the ColdFront™ Heat Exchanger, there was no power loss at all after the back-to-back dyno pulls.
Results are even more significant with the ColdFront™ Coolant Pump equipped in conjunction to the other components, which can be seen below:
