the skyline team were claiming 600bhp so if that was true then the sierra would need 600+ to pull past them on the straights as waight wasnt much different and didnt Dave Brodie claim a 600bhp motor aswell?? though he got penalised for illegal fuel which gave him extra umph
The advantage trackstar had over AR was their yokahama tyres, they just didnt wear out like AR's dunlops, in 1990 trackstar were proper on it. shame they lost there sponsers, prob cause mike couldnt keep his sieera on the track without bending something lol
