He already has a 2nd gen. '86 I believe but I might be wrong. That's what he's working on apparently, although I hadn't heard anything about it.
I just can't respect those electric blowers. They're tiny, inneficient blowers to start with, and they're turned by a starter motor, powered by a BANK (not one, but a bank) of batteries. The weight of those items has to very nearly cancel out any gains you get from the supercharger itself, for all 15 seconds of it's operating life before it has to recharge for a few minutes.
To give you an idea of how little these are, the maximum safe flow rate of the Powerdyne bd-11a in the WOMP kit flows 975 cfm. Like Jamie said, the TK units flow under 400 cfm. It's just not a good use of money.
