I've been curious about the water temps of the aftercooler while on the track. Starting at 70F, after a 20 minute session it hits 95F. This is with a very large cooling area (think of a bumper with a lot of 3" holes - racecar), so it would be much higher without. It was 65F out today.

8psi on AP1 FWIW

Not as bad as I thought it could be, but certainly not great.

check out this site for info with aftercooler water temps

Im bascially making a custom version of this

Anyone using the aftercool from Ultimate-Racing?

 

Time for some testing, because those numbers seem too good to be true.

 

Heres another thread related to the topic that anwsers some questions https://www.s2ki.com/forums/index.ph...pic=522829&hl=

 

Independent test is the only way to know for sure.

 

Nice set-up but $950 I don't know, seems kinda high to me.

 

not really, when you think the Comptech aftercooler is like $1200, isn't it?

 

Bill,

I was thinking about this. This may sound silly, but I was thinking that I am going to take a cooler with lots of ice and a couple gallons of distilled water to my next track day. I bought a siphon for $3 from a local parts store and I was thinking that I would siphon the old water (& a bit of water wetter) out of the aftercooler and add the cold stuff just before I head out to the track. That should help in the short term for 20 minute sessions.

In the long term, maybe an aftercooler sprayer using methanol might be a good setup?

Just a thought...

i agree here...seems fishy. i cant imagine the comptech unit being so inefficient. my budy has a jackson charger on his crx with a gsr, boosting about 15psi and that thing unintercooled hits 200intake temps. so your telling me the comptech aftercooler only does around 20% efficiency? sounds bogus. the air to water setup for the jackson is near 90% effcient. i would imagine the comptech is somewhere near there.
