Hyper 7 Pinion? - 07.14.2008, 10:13 AM

Ok i have a hyper 7 and a MM and 8xl running 4s. What pinion will keep things cool enough to run you think? I tried Brian's calc but it is down right now. Looking for a good track buggy speed wise. So around 35-40mph but keeping electronics cool. Placing an order today so need to know what pinion to get.
Thanks guys.
