As soon as the MSD rolling road is in an working we will know how well they operate and what the recovery time is.

I'd put good money on these coolers in question being close regardless to the Garrett core as it was exactly the same last time they were tested but Pete's recovering slightly quicker, thats my guess.
But for the money i payed for my cooler i could have bought 4 to Pete's 1 Spec R 100mm so £ for performance the Airtec wins hands down.
