I would talk to JKM about circa 500bhp in a fwd. Their Octavia is running 520 currently and they run an ECU from these people:
http://www.syvecs.co.ukI've ridden in it and the delivery is devastating and beautifully controlled. I'd say it's too fast for the road in all honesty but they have it as a technical showcase and a forthcoming 200mph fwd record attempt.
Within this ECU are some very well engineered traction control systems, amongst other's that are non existent in standard ECU's. It will protect your drive train in a way that a standard one simply can't. It will let you do a foot flat launch without any loss in traction. No spin or wheel hop...just grip. It's a mind boggling experience and I would say it re-writes the rule book for fwd, but it's not cheap.
Done properly this will cost many many £'s.
