One of the problems with an aftercooled supercharger, is after your track session, when you stop the car, the aftercooler coolant starts absorbing heat from the engine bay. When you go out for your next session, the AIT (air intake temperature) can easily be up by 15-20 degrees, and it can take 5 minutes or so for them to come back down once air starts passing over the heat exchanger, which is about half your session.

How do people get around this problem? I'm running the AEM series 2, is there a way to trigger one of the fans to come on based on AIT, so that while waiting for your session, intake temps will be coming down. I thought about blasting the heat exchanger with a C02 fire extinguisher, yes, no maybe?? F1 style pit crew with leaf blowers?

Any ideas appreciated, thanks.

 

Connect your aftercooler waterpump to a constant 12V supply and install a toggle switch. When you pull in the pits, you can keep circulating the water in the heatexhanger/aftercooler.

 

I would run the AEM Meth injection kit, but just spray straight distilled water on the smallest nozzle. It works wonders

 

Interesting. My SOS setup with the upgraded heat exchanger would drop my IAT's by 20-30 degrees as soon as I hit 45mph or above. That's on the street - sit in Hotlanta traffic going nowhere for 10-15 minutes, then finally get moving and temps immediately drop. What setup are you running? 5 minutes sounds like a really long time for a heat exchanger to do its job, especially at high speeds on a track.

 

I'm running the newer Vortech with the larger heat exchanger. It is currently filled with 100% coolant which would be impeding it's heat transfer capability, the guy who installed it decided more is better and ignored the manual's 50/50 water/coolant instruction. I plan to try water and redline water wetter at some stage.

 

Can't you put ice in the aftercooler to lower iat?!

 

I've seen guys buy bags of ice from the snack shop, then lay it on the intake manifold. They push their car in the staging lanes until its time for the burnout. Could do the same on your aftercooler or the toggle switch on the coolant pump sounds good too, except I wonder how good the cooling would be because you are sitting still and not moving. Has to help somewhat I would guess.
