When they are talking about clipping they are strictly talking about the turbine wheel, they clip them on angles, 5*, 10*, 15* etc, Although this does hurt spool slightly it does increase top end, with a 14B being such a quick spooling turbo clipping the turbine wheel a few degrees should yield a negligible increase in lag, but also keep in mind this is for drag racing applications were every little bit of top end power counts, especially when dealing with a turbo that probably flows 35 lbs/min, thus lag is really a non issue.
Carver we should both put 14Bs on our cars and have a little Meth VS pump gas run for fun :P But in all seriousness I have had multiple 14Bs spin the compressor nut off during 23+ psi blasts
