I am an ex-silver Rose (944 Turbo S) owner. I never raced a 300 TT but I have in my 350 BHP 928 GTS (5.4 V8, 32v, 4 cam). It was one of the car modified by 'Fairlady' with a race bodykit, suspension and tarted engine. It matched my car for acceleration better than an Audi S8 or one of the new baby Ferrari's and the handling was top notch. According some Nissan club guys at the NEC a fairlady is 400+ Bhp. Very good car but the 944 Turbo is a true supercar.
