RE: GST 7.7 Gasser finnished..
the pipe still will not deliver the power of a tuned expansion chamber...it'll give performance similar to a can or x-can which is about 50% less than the engines full potential. here's a good explanation of how it works [link]http://en.wikipedia.org/wiki/Expansion_chamber[/link]
99% of us here have run nitros in the past so know the difference in part beefiness between 1/8th and 5th..it's pretty substantial, so not being negative just informing you,from our experience with such things, that the drivetrain will be an issue if you expect to bash it like you would a true 1/5 rig. I have seen one of these up close (my buddy has one sit on his shelf, where it's been since he converted it) and had a good inspection...if you're going to just pootle around it'll be fine, give it the beans though and you may have some issues.
