I was considering switching from Buggy to Truggy and would like feedback on the Go 5 Port and 7 Port for the truggy.

Which engine would be better overall for the truggy? I would be running a stock engine. I am thinking the 5 Port would be better, because it has very good low end power.

I am also hearing good things about the '08 version 7 Port with the 0801 pipe. Would the 7 Port have enough low end power for a truggy, especially on an indoor track?
