I like this idea blowpopracer! I had a OS .21 VG and it will last a season and then throw it away. I think the a RB S3 might work for what you want and throw in a smaller venturi insert.

If you're trying to soften the low-end, you can use light clutch springs, composite clutch shoes, a larger pinion gear, and richening the low-end needle. Also, if your radio has exponental, you can flatten out the low-end throttle curve. The best way to control low-end punch though is of course concentration and throttle control and practice practice practice, but you knew that.

Will running a restrictor take away some of the low end? I know limiting throttle travel only takes away the top and what I want is a engine that has very little punch off the line.
