I agree that you can get those small blower to perform quiet well but you really have to work them very very hard. This sets them up for fialure. I would rather go with the f1 over the d1. It can easily make 9sec power and leaves enough capacity to go faster down the road. Also it iwll last longer then a tottaly cranked S-trim.
Nice part is that the f1 vs the d1 is not a huge price increase during kit purchase time.
