I have a local customer running an X-Ray buggy. He's running the GX7R with the 2072 pipe and has all the bottom end he needs. Our local track is a relatively fast, open track with jumps right after turns. He never fails to clear the doubles and triples with the short run-ups. Gearing, clutching, tuning, and even chassis set-up have MAJOR influences on how a vehicle pulls coming out of corners.

The GX7R has plenty of bottom end for a buggy. I haven't seen an engine that can out-rev it on top end.
