Just tried a 7 port Go with around 1.5G on it.
Not much power down low and good top end.
I personally wouldn't use it in a buggy or truggy.I'm used to V-spec power and on the 7 port it just isn't enough.
I used it with 1.1 clutch springs and JP-1 exhaust and didn't like the bottom end at all.
I don't know how the 5 port will perform but i will try it out soon.
