My supercharged ST170 was around 300bhp last year and i pedalled that around with no wheelspin/torquesteer issues at all...
I'm going for around another 100bhp this year and suspect i'll only be traction limited with the nitrous in 1st and 2nd...
I think a lot of people overlook the chassis/suspension/geometry and tyres when building fast FWD cars and then moan that "they're all over the road"...
