Possible?
Maybe if you're measuring at the crank. A couple of guys here are putting down enough power that at the crank they just might be making over 1K (and at least one that IS) but this guy?!
Umm, no way. T66s are for small 4cyls?! Oh, and he's running two turbos - some HKS turbo I didn't recognize (someone look it up) that he claims no one else has? I seem to recall Suprastore had a set of one off (in the States) HKS twins but I'd bet the numbers don't match. $5 says he picked up a copy of Sport Compact, got a woody, and like a few twits who post here occasionally, decided to yank some chains. Gee, it worked too didn't it?
Lol, reading that guy's comments is like watching F&F to pick out the bloopers. 850CFM injectors? um 850CC maybe. The T66 thing. "Special" Carillo rods

Lowering the compression to stock levels (lol). I got lot's to learn yet - what all did I miss? We could start a contest to find the errors - too bad they closed the thread
Hrm, and to the VW guy who claimed you can't idle with 850CFM injectors (lol) because there's no computer that can do it (cough). That's not true obviously. Besides, it's not the computer that would probably be having the problem if there was an idle issue - it would be the hysteresis in the injector causing it to dribble due to it not opening properly. So far as I know though Supras have no issue with 850CC injectors.
