Would be awesome to see some before/after cooling data for the various systems of the WPX system on a stock LT4. Also, any information on the warranty for these guys for leaks/etc? Also assuming you need to bleed the system of course after install, which would require an aftermarket expansion tank on the OEM blower, or a trip to the dealership for the pressure bleed procedure.

For what its worth.. I didnt have any losses on repeat pulls for my bone stock 19 A10 ZL1 in 69 degree heat (high humidity and warm dyno bay). Dyno attached stock (ignore the lower curve, thats my previous car for comparison).

Also, the OEM coolers are thinner by design to allow more flow at low speeds for non-dedicated track cars. Obv thicker is better for track dedicated cars but if you daily it a lot, may not be best to have the bigger cores unless you have lots of mods.
