WTB: Cobra Heat Exchanger
Hey guys, long time no see.
Looks like I'm in need of an OEM Cobra or Shelby Heat Exchanger.
Based on the last one I bought, looking for around $50 to $100 shipped to 85303 (Glendale, AZ).
If anybody has one for sale or can direct me towards one, I'd greatly appreciate it.
Thank you guys,
Jay

Edit: Not sure what's up with that angry smiley, lol.
I used to have a ZZP S3 H/E, but oddly enough I noticed an increase in IATs. This is using the Dual Pass Endplate as well. When I switched back to the Cobra H/E, the IATs dropped back down.
My best guess was that the ZZP S3 was too large in surface area and volume, which caused the flow of water to slow, or the Dual Pass Endplate allowed the water to flow too freely, resulting in poor heat transfer.
On top of that the car began to overheat on the freeway with the ZZP S3. I live in AZ so I use the A/C for 11 months out of the year. What I found out was that when running the A/C the PCM shuts down the fan at speeds over 65 MPH in order to prevent the air flow for over running the fan motor and also assuming that the air flow at those speeds is sufficient to cool the condenser and radiator without assistance. When I put the Cobra H/E the problem resolved itself.
My best guess is that the larger spacing between the fins on the Cobra H/E allowed more air to flow through to the condenser/radiator, and vice versa, the tighter spacing between the fins on the ZZP S3 reduced the air flow going to the condenser/radiator significantly.
Of course this is all speculation.
My new plan is to use a pair of Cobra H/E on the 2/3 of the condenser/radiator area that are not exposed to direct air flow with their own dedicated Spal cooling fan. Each H/E would be dedicated to it's own pass from the Dual Pass Endplate. This way the lower 1/3 is exposed to direct air flow without any obstructions, therefore maximizing condenser/radiator cooling.
Something to try out.
