I got around to installing the IC right after Christmas and have had it in the car for about two weeks now. After lots and lots of highway pulls, I've noted lots of improvement although it's mixed bag. Nothing bad, it's just that this upgrade will really go hand in hand with supercooler as the stock heat exchanger won't let you realize the full potential this thing has to offer. It really takes the heat out of the air charge and by really, I mean you can saturate the coolant in the IC circuit with heat very quickly if you're flogging the car. I'm running a relatively small heat exchanger and when the coolant is cool, the IATs stay cooler for longer than they would with the factory IC for about half a highway pull. After that, they're at the same temps as they would be with the factory IC. If I had more capacity in the cooling circuit, this would be extended as there would be more coolant to heat up and if I had a more efficient heat exchanger, it would keep it cooler, longer regardless of the volume.

The other benefit is the motor is no longer ingesting coolant. A factory core would have fixed this problem but only for a while and the longevity with them just isn't there. My second factory IC only had 35k on it when it wet the bed (no pun intended) so it's just a matter of time before I'd have to replace it a third time due to it cracking and leaking cooling. Those problems that plagued the factory core aren't an issue with these due to the difference in core design and manufacturing and these cores are capable of 500HP and 2.5bar (~36PSI) so pretty much anything these cars can throw at it, it will easily handle.

Price is $1000 and there is a 2-week lead time on them from the time the order is placed as they are being manufactured on an as-ordered basis.

Please email me at rcompart@gmail.com for more information or to place an order.

serious shopcam recomendation....



BTW nice visiting the whiplle website, copper i/c cores? BA

No - I mean all respects - great work!
Did you try to source a copper cooler but had to settle for aluminium?
My calcs are showing copper maybe significantly better.

To put 50-80% into perspective, Waldig's doubling the flow rate from 2-4gpm (series CAC) yielded a 10% increase in heat transfer to the air (assume similar in reverse).
Rcompart - Have you any leads as to a source for such a suitably sized unit in copper?

As for the inlet and outlet heads - yes machined copper would be tedious for a single unit.
There isnt any significant loads on the unit as it sits and hangs under the charger so I wonder if it would be more economical to do them in cast brass, rather than machined copper (if production was stepped up to >5units).

Preaching to the converted.....but it still comes down to the weakest link - the CAC maybe able to "do da bidness", but the IC may not.

Building an intercooler with a copper core will cost north of 3 grand and unless you're running an ice tank, you're not going to remove enough heat from the coolant with the aluminum core intercoolers we're building now so a copper core wouldn't do any better.

CAC = charge air cooler - the one under the supercharger....
IC = the intercooler behind the front bumper....

"Cool"....
.....but can someone shed any light on the question....
"Have you any leads as to a source for such a suitably sized unit in copper?"
names, links, info? I understand this might be considered IP - and I'm fine with that if you dont want to divulge.
Eg: .......Allied Heat Transfer

or with fear of possibly really over stretching the friendship .....maybe some dims A,B,C as per image attach....PM me if you like.

Thanks Rudy for all the great work you do for us. jim
