Low-Temp Cooling Loop

This brings us to the Hellcat's knock-out punch—the supercharger's low-temperature coolant loop. Here's a little known secret: In the boosted powerplants of most manufacturers, the rated horsepower is only valid under normal highway use for a limited period of full-throttle time. For safety's sake, once the air charge temperature elevates to levels where detonation and knock begin (such as at a race track) the engine controller limits ignition and boost to save the engine. This is called de-rating. When you see guys at the dragstrip packing their manifolds with ice before a run, they're trying to avoid de-rating the power of their engine.

With the Hellcat, the air-to-liquid intercooler operates on a low-temperature cooling circuit that is independent of the engine's cooling system. Competing powertrains operate on the same high-temp cooling loop as the rest of the engine, limiting their intercooler efficiency. By running a low-temp loop, the Hellcat's two heat exchangers—one in each bank of cylinders—can produce a much greater temperature differential. This system is so effective that the Hellcat can be driven for 20 laps on a 3.1-mile road course in 100-degree ambient heat without the engine power de-rating. (Among one of the torture tests Dodge engineers conducted was a grueling 24-hour endurance test at Nelson Ledges road course in Ohio.)

Quick question folks: Is this supercharger set up a possible swap for the ZL1? Has anybody considered anything similar. This low temp independet loop sounds like it could be the future of FI. It definitely makes more sense to run a supercharger that temps are regulated inedependent of the engine. What do you real deal car gurus think? I've seen videos and the hellcat is eating cars alive from a roll...demolished a C7 Z06 by the way. Its not too shabby from a dig either...if they can get traction.

They make a twin screw for the SS and ZL1....just sayin..

It's not just the twin screw supercharger I was discussing...did you read my post in its entirety? Does that twin screw operate with a similar cooling system? And more importantly....has that twin screw proven to be a far better setup than what we currently have?

Seems to be working good for these guys...

How is the supercharger cooling system (intercooler) different then the LSA besides having 2 heat exchangers in the SC and 2 front mount radiators?

Hellcat supercharger is clutched and will make a retro fit somewhat more difficult. (It's also Korean I believe)

The most comparable thing I know of available to us is the Heartbeat blower. (Put that is still a roots blower).

The Hellcat has higher boost, more compression, better flowing heads and a more agressive cam. The LSA boost, cam and heads are very mild in comparison.

OP, I get your point, and it is a good one. I do not have the answer, but if I owned a ZL1, you can bet I would be finding a way to do this.

LSA intercooler temps are independent of the engine, the 2 systems do not mix coolant. Our intercooler system is the same other than we have 1 intercooler brick in the super charger where as the hellcat has 2 bricks over the intake ports. This is very similar to the magnuson heartbeat supercharger that also has 2 bricks.

Basically you just want larger intercoolers in the supercharger to have a larger contact surface area with the hot air.

Both the hellcats blower and the magnuson heartbeat blowers intercoolers will be very similar in size....the heartbeat may actually be bigger fromt he pictures i have seen of both blowers.

The other thing the hellcat has going for it is the blower is 2.4L compared to the LSA which is 1.9 and the LS9 is 2.3 and the heartbeat is also 2.3L
