Can anyone direct me to a artical/turorial descussing the inner-cooler design. The type of materials, structure, flow rate and an internal view etc. John

 

How Stuff Works ???

and it's intercooler that you're looking for... not inner

 

lol "inner"-cooler

 

My guess is there isn't information out there other than the usual basic stuff, so we just plunk out a grand for a funny radiator. Nope build it and learn a lot in the process.

 

There's a LOT more to it than that....you can ask Kevin (ASP). He doesn't make much money off of his $1500 kits....

Most of the SMIC kits have had a lot of engineering put into the design and fitment. If you have access to a metal shop, I suppose you could save money but you'll also waste a hell of a lot of time. I remember several people buying cores with the intent to make their own intercooler setup over the last few years. Almost all of them gave up, sold the core, and bought a kit.

 

Thanks for the input, no one says it's a easy build. You mentioned buying cores? Would you have more info as to where you can purchase them? John

 

you can buy cores on the internet for real cheap..

Not worth it though, buy a sparco front mount off ebay. Its not the real thing but its an identical unit. They take a sparco core and make custom endtanks. Its a good size front mount for about 400, and yes they are good quality. Read the guys reviews. Anyway, for 400 you couldnt touch any other intercooler of that quality let alone build one yourself. You must consider your oppertunity cost of making and intercooler, guarantee it aint worth it. Your time is better spent doing what you do best.

Specialization my friend.

O.C = (what you give up / what you gain)

O.C > 1 your wasting time and money.
O.C < 1 proceed.

 

Several companies make IC cores. Just use Google and search for "intercooler core buy" or add in "Spearco".

 

I see the benefit of ebay, I use it often. I see gaining a skill as the benefit. I am not saying a pro skill level here just having the ability to expand to other mods which would be your custom design. Maybe todays racers are bread to think this way. Don't get me wrong, there are some things left to others. I spent 20 years doing tune-up and drive-ability and had to adapt to changing designs, thus was always open to new often frowned upon ideas. I have seen the units on Ebay and thanks to your input in this case you make a good case. John

 

The main problem is that most people just end up copying another design. Once they have a core, they need to figure out the end tanks, so they look at other IC's and copying one of their designs. After that, they need piping, so they look at other IC's and end up copying that as as well. In reality, they didn't do any "research" only copying and spent the same amount of money as one of the kits would have costs in the first place.

If you are really interested in IC design, search for posts here by "Kevin T. Wyum". He has posted a wealth of knowledge about IC design on the forum.

 

You basically need a decent core, decent end-tanks, appropriate piping, and a good duct.

The key is to find a core without a high level of pressure loss for the level of cooling it provides - which will mainly be in how aerodynamically efficient it is.

Thanks for the link the articles are great!
