I use a WoLo bad boy on my Ryca, but space might be a problem on a stock machine. They need a rely and also draw 20 to 30 amps depending on what model you choose. I used the 20 amp circuit that was freed up when I did away with the compression solenoid. Only drawback, it's active with the key off (don't tell the kid next door). I don't know what people expect to see when I blast 'em with it, but it sure gets their heads up.
