V Specs are Great, Easy to tune, Have 4
WS7 II _ great for buggy, tune well, Have 2
Any SH engine, great price, tune well, and budget freindly, Have 4
I am currently running a GRP in Buggy an V spec in Truggy
GRP makes good power, But I have had some issues with It, I have ran about every engine out there, and depending on your budget I would reccomend the top three to start with.
