I'm running a permacool one on mine, with their sandwich plate and inline thermostat. It's their 250hp rated one, partly cause the shape fitted better than the 150hp one, but mainly for headroom in case of future mods and i just figure better safe than sorry. It's sees the track fairly regularly so i went a bit bigger and got the thermostat, which means it's perfectly happy cruising at 80 on a wet 10 degree night or seeing 8k rpm round wakefield in 30-odd degrees.
