if this is for racing and you have great car handling abilities, look into something like a 10 - 12 turn motor.
I run a 12 turn double Peak Vantage ( V2 technology ) and its great. Runs a long time before rebuilds.
Personally, if you could get a 19T class going I would look into that. 19 turn buggy racing is quite fun.
Don't be put off by running the 19 turn motor till you get a mod motor or feel more comfortable with the speed.
