Muscle Mustangs and Fast Fords actually did a Non-PI build-up running a centrifigal super and worked non-PI heads that put down around 600 RWHP.
2V-PI engines are capible, if built correctly of numbers near 800HP and still semi street-able.
Yep, there are turbocharged 2v's pushing past 900rwhp and possibly onto 1,000+, though VERY few as of now (look for travers a customer of Steen Racing). There have already been centrifugally supercharged ones pushing damn near 800rwhp (maybe above by now). Kenne Bell and Whipple supercharged 2v's have easily surpassed 600rwhp and are quite common within the Mustang world. Now by "common" I do not mean that everyone has one, but they are not shrouded in any kind of mystery. Some off those KB supercharged ones has topped well over 700rwhp with a small shot of nitrous. I myself will be shooting for well over 600rwhp on the Kenne Bell next season and 700+ with a small shot of nitrous if I do not end up swapping to a pair of turbo's first. If I do the turbos then I will shoot for 800+ rwhp. All these numbers mentioned are of course with FULL supporting mods such as worked heads, cams, built bottom ends, big fuel systems yadda yadda yadda.
And yes I can personally vouch for making this kind of power as being extremely extremely expensive. Take the amount of cash I dropped into my fuel system (for parts alone) and multiply it by 2 and you damn near have as much as I am doing the turbo system on my LS for. Not cheap.
