What is the advantage of the intercooled version from Comptech? Is it best suited for really hot climates?

 

Its best suited to lower your intake charge temp thus preventing detonation.

 

There is a Intercooled version or do you mean aftercooled... ( I am not being a wise ass I am actually asking )

 

It is aftercooled.

 

Lower charge temps (regardless of method; i.e. water injection, intercooling, aftercooling, etc.) In turn produce lower combustion temperatures. Lower combustion temperatures allow you one of two benefits.

You can either take advantage of them with the same tune and an added level of safety, or use the lower temps as a buffer zone to change your tune, either with added timing, slightly higher boost levels, etc. However that all depends on your current tune and setup.

Colder charge air is also more dense, and more power will be produced.

In conclusion; colder = better

 

Originally Intercooler and Aftercooler were two terms derived to explain the same thing. Cooling of charge air 'after' the compressor or 'in' between the compressor and head. I think there may have been a difference in carburettor days with regards to where the carby was but it is irrelevant with fuel injection. Today it is common (although not necessarily correct) to describe air-air cooling systems as 'intercooler' and air-water systems as 'aftercooler'.

I believe the reason Comptech introduced the aftercooler is because of a 'perceived' need from a marketing perspective. When Comptech originally produced their kit they didn't feel charge cooling was required with the low boost and rich fuel fix. And the advantage was a very short undisturbed charge path. The Vortech came out with their Air-Water cooled SC and the public started saying 'Vortech comes with an AC, Comptech doesn't'. So Comptech introduced the AC to level the playing field.

I ran a nice Comptech system with 8lb pulley for over a year with no AC. I recently added it and can't percieve a difference. That said, I expect it would give me more safety margin or scope for aggressive tuning should I wish to put it on the dyno again.

 

I think a intercooler is for cooling the supercharger case. as in a two stage supercharger. it cools between the impeller housing. a good example being a roll-royce V-1650 "merlin" aircraft engine. acorrding to the info I have read on the subject. however this may apply to any supercharger with a cooling stage, as aus2000 has stated.

 

It appears you are correct. I did a Google on Aftercooler and Intercooler and the difference is that an intercooler is for cooling charge between stages of compression.

I guess you could argue that the first stage of compression is the supercharger or turbo and the second stage is the piston compressing the charge before combustion (certainly makes sense in diesels) and hence 'intercooler' is applicable (and by the same argument 'aftercooler' is not) but otherwise it is a misnomer.

 

how about an aftercooler AND an intercooler
