How much are you talking for the DP kit Nick?
To be honest I was going to do it. The two days we were on track in Almeria were 20 degree's and sunny (ahhh,
) and we were running half hour sessions. The track is quite big with a 1km straight so the little thing was working. It was hot after every session. As in flashing hot!
But as I say, the advice I got on it was to keep changing the oil regularly, and filters and you should be fine.
