Not really that extreme, CEN truggy on 5s with mmm, 1515/2.5d geared 46/15. I don't know that I need the extra cooling I just wanted to have all the bases covered before my first race with it coming up and unfortunately due to the weather around here I doubt that I will be able to test it on anything resembling a track. If you guys think its a waste then I wont even worry about it. What do you think?
