    Here is the only ZR1 kit that I shipped. ZR1 is not ready yet so wiring and water lines did not ship and not pictured but you can get good idea what is included.

    The Active InterChiller works as advertised, so far. 78* ambient cruised 20 miles at 70MPH -IC water temp was 127*. Turned chiller on same trip, same speed - IC water temp 44*. Can't wait to start adding timing back in!

    Re: The ultimate intercooler upgrade!

    Ok that sounds great but 70mph is far off of wot at 100+mph at 19psi. What I want to know is what is the iat2 temps at speed and wot. when I dynoed my car last week iat2 was 10* higher than outside air temps. And at wot it went up to 155* max. So it was 68* when I dynoed so I want to know what your temps go to under close temps at wot.

    What is your intercooler water temp during above conditions? That’s what will tell you how efficient intercooler is working. If water is hot intercooler is working if water stays near the same then there is no heat transfer. GizmoQ will have more info for you soon. I believe refrigerated water will cool IAT2 better than hot water even on a Northstar.

    Re: The ultimate intercooler upgrade!

    Did some data logging on the 1100mile trip home. Without the chiller cruising at 84 the modified pump and intercooler surprised me. With no chiller, IC water temp stayed right around 114* (lots of air coming in at that speed). Interestingly, the Active Interchiller at that speed only got the IC water temp down to around 69*. Hmmm. Maybe that was because it wasn't in competition mode (forgot to flip the switch).

    Re: The ultimate intercooler upgrade!

    I do not know what my ic water temp is. Never checked it only iat2 before big fount mount heat exchanger. Iat2 would go to 180-190* in 45* weather now only 155* in 65* weather.

    I would say if AC was good and cold that the blower was making a lot more heat at that speed and intercooler was working well transferring heat to water. We knew going in this would not be as efficient as a Maggie on a LS3 thatís why I increased chiller size 30%. Thatís still around 45deg improvement. We still have the option to try adjusting the Super Chiller Valve. We just plain ran out of time or I would have made 1 more adjustment. Your Freon charge is now 1lb 5oz btw. What about ICWT when youíre stopped and chiller is off how fast does it climb? Your new water tank helps with or without chiller too.

    IMHO youíre big fount mount heat exchanger does not help much when youíre going slow or stopped. Donít forget when AC/Chiller is on heat exchanger is not used. Chiller will keep water cold when stopped going slow or fast air flow is not needed at all.

    Re: The ultimate intercooler upgrade!

    As soon as I slow down under 50MPH, ICW drops to 41-47* in traffic. When chiller has run for 30 minutes or so and turned off, temps rise back to normal about 30 minutes later. The extra tank makes a big difference. The water in it is cold, the tank is cold, the line to the SC is cold - so the all take a while to warm up. Works great, Dave. Good job on the storage tank.
