But this unit is rated to 350bhp and it's more than twice the size of the TX Autosport cooler I was running, which is basically rebadged, cheap Chinese eBay crap and that allegedly can run up to 400bhp. Even if the Airtec figures for it's own cooler are at the maximum side of things, it still suits me fine, as I probably won't up the power any more than that anyway. Stage 3.5 in a Corsa shell is nuts enough as it is.
